Description

Technical Field

[0001] This application relates to the field of equipment control, and more particularly to an equipment control method, central equipment, and device. Background Technology

[0002] With the development of technology, more and more electronic devices have entered households, improving people's quality of life.

[0003] Among these electronic devices, some may record users' private information, such as smart speakers recording users' music preferences and smart screens recording messages users leave for other family members; some electronic devices may involve users' personal and property safety, such as cameras that can monitor whether someone is illegally intruding.

[0004] However, these electronic devices are usually unprotected by visitors. Therefore, when there are unfamiliar visitors in the home, they can freely view the user's private information, leading to the disclosure of the user's private information; moreover, unfamiliar visitors can also operate security equipment without authorization, posing a serious threat to the user's privacy, personal safety, and property security. Summary of the Invention

[0005] This application provides a device control method, central device, and apparatus that can solve the problems of existing whole-house smart control solutions being unprotected by visitors, easily leaking user privacy, and causing unauthorized operations.

[0006] In a first aspect, embodiments of this application provide a device control method applied to a central device, comprising:

[0007] When a user is present in the home area, obtain the user's identity; the user identity includes family members and / or visitors.

[0008] When the user identity includes the visitor, enter visitor mode and instruct the controllable device to enter visitor mode, and / or assist the silent device in protecting privacy information and / or restricting sensitive operations;

[0009] The controllable device is an electronic device that supports guest mode, which is used to protect privacy information and / or restrict sensitive operations. The silent device is an electronic device that does not support guest mode.

[0010] It should be noted that when a user is present in the home area, the central device can obtain the user's identity. The user's identity can include family members and / or visitors.

[0011] Among them, the central device can receive user characteristics sent by the detection device, process the central device characteristics, and obtain the user's identity;

[0012] And / or, the central device can also receive the detection results sent by the detection device and determine the user's identity based on the detection results.

[0013] The aforementioned user characteristics may include one or more types of characteristic data such as facial information, fingerprint data, access control passwords, sensor data, and voiceprint data.

[0014] After obtaining the user's identity, the central device can identify whether there are any visitors among the aforementioned user identities.

[0015] If the user identity mentioned above includes "visitor," it indicates that a visitor has entered the home area. In this case, to prevent the visitor from viewing family members' private information or performing sensitive operations without authorization, the central device can enter visitor mode, and instruct controllable devices to enter visitor mode as well.

[0016] Controllable devices refer to electronic devices that support guest mode. Guest mode is used to protect privacy information and / or restrict sensitive operations.

[0017] Furthermore, for silent devices that do not support guest mode, the central device can assist silent devices in protecting privacy information and / or restricting sensitive operations.

[0018] By employing the methods described above, the central device can prevent visitors from arbitrarily viewing family members' private information or performing sensitive operations without authorization. This effectively reduces the possibility of privacy leaks and unauthorized operations, protecting users' privacy, personal safety, and property security. It is highly practical and easy to use.

[0019] In one possible implementation of the first aspect, the visitor mode includes one or more of the following operations:

[0020] The privacy information is anonymized, the privacy information is hidden, the access point to the privacy information is hidden, the execution of the sensitive operation is prohibited, the access point to the sensitive operation is hidden, and identity verification is performed when the sensitive operation is detected.

[0021] It should be noted that in guest mode, electronic devices can protect privacy information and restrict sensitive operations through one or more of the following protection strategies: anonymizing privacy information, hiding privacy information, hiding access points to privacy information, blocking sensitive operations, hiding access points to sensitive operations, and performing authentication when sensitive operations are detected.

[0022] For example, in some cases, when an electronic device receives a voice message in guest mode, the device can anonymize the voice message and announce, "You have a new voice message. Please view it on your personal device," thereby hiding the details of the private information and prompting family members to check the voice message on their personal devices.

[0023] In other examples, when an electronic device enters guest mode, it can directly hide private information such as photo albums and contacts, or hide access points to this private information, thereby preventing users from arbitrarily viewing the private information of family members.

[0024] In other examples, when an electronic device enters guest mode, if the electronic device detects a sensitive operation, it can block that sensitive operation and not respond to it.

[0025] In other examples, when an electronic device enters guest mode, it can directly hide the access point for sensitive operations, thus preventing users from accessing the interface for sensitive operations and performing sensitive actions.

[0026] In other examples, when an electronic device enters guest mode, it can authenticate the user if it detects a sensitive action.

[0027] If authentication is successful, it indicates that the user performing the sensitive operation is a family member, and the electronic device can respond to the sensitive operation; if authentication fails, it indicates that the user performing the sensitive operation is not a family member, and the electronic device may not respond to the sensitive operation.

[0028] In other examples, electronic devices may employ other protection strategies to protect privacy information and restrict sensitive operations. This application does not limit the protection strategies adopted by electronic devices.

[0029] In one possible implementation of the first aspect, the auxiliary silence device protects privacy information and / or restricts sensitive operations by one or more of the following operations:

[0030] When a sensitive message is received destined for the silent device, the sensitive message is anonymized to obtain an anonymous message, and the anonymous message is forwarded to the silent device. The sensitive message includes the privacy information.

[0031] When a sensitive message is received destined for the silent device, the sensitive message is intercepted;

[0032] When a device control command is received from the silent device, the device control command is intercepted, and / or the operation corresponding to the device control command is prohibited from being executed.

[0033] It should be noted that when the central device assists the silent device in protecting privacy information and / or restricting sensitive operations, it can select an appropriate assistance method based on the actual scenario.

[0034] For example, in some cases, when the central device receives a sensitive message destined for a silent device, because the sensitive message contains private information, the central device can anonymize the message, hiding the private information within it, thus obtaining an anonymous message. The central device then forwards the anonymous message to the silent device, reducing the likelihood of the silent device leaking the private information of family members.

[0035] In other examples, when the central device receives a sensitive message destined for a silent device, the central device can also directly intercept the sensitive message and forward it to the personal device of a family member, thereby protecting the privacy information of the family member.

[0036] In other examples, when the central device receives a device control command from the silent device, if the command is intended to control other electronic devices, the central device can directly intercept it; if the command is intended to control the central device, the central device can choose not to respond. By intercepting and / or disabling the execution of device control commands, the central device can reduce the likelihood of visitors performing sensitive operations through the silent device.

[0037] In other examples, the central device may also assist the silent device in protecting privacy information and / or restricting sensitive operations through other auxiliary methods. This application does not limit the specific form of the aforementioned auxiliary methods.

[0038] In one possible implementation of the first aspect, after entering guest mode when the user identity includes the guest, and instructing the controllable device to enter guest mode, and / or assisting the silent device in protecting privacy information and / or restricting sensitive operations, the method includes:

[0039] When the preset exit conditions are met, exit the guest mode and instruct the controllable device to exit the guest mode, and / or, no longer assist the silent device in protecting privacy information and / or restricting sensitive operations.

[0040] It should be noted that when the preset exit conditions are met, the central device can control the central device and each controllable device to automatically exit the guest mode, and stop assisting the silent device in protecting privacy information and / or restricting sensitive operations. This eliminates the need for the user to operate each electronic device individually, reducing the user's workload and improving the user experience.

[0041] In one possible implementation of the first aspect, the preset exit condition includes one or more of the following conditions:

[0042] A family member's logout was detected; no users are present in the family area; no visitors are present in the family area.

[0043] It should be noted that the preset exit conditions can be set according to actual needs. For example, in some examples, the preset exit condition can be the detection of a family member's exit operation. In this case, if the central device detects the exit operation, it can authenticate the user. If authentication is successful, the central device can respond to the exit operation; if authentication fails, the central device will not respond to the exit operation.

[0044] In other examples, the preset exit condition can be the absence of users in the home area. In this case, if the central device determines that all users have left the home area, the central device can control the central device and each controllable device to automatically exit guest mode, and to stop assisting the silent devices in protecting privacy information and / or restricting sensitive operations.

[0045] In other examples, the preset exit condition can be the absence of visitors in the home area. In this case, if the central device determines that all visitors have left the home area, the central device can control the central device and each controllable device to automatically exit visitor mode, and stop assisting the silent device in protecting privacy information and / or restricting sensitive operations.

[0046] In other examples, the preset exit condition may be other than what is specified. This application does not limit the specific content of the preset exit condition in its embodiments.

[0047] In one possible implementation of the first aspect, the visitors include a first type of visitor and a second type of visitor, wherein the operation permissions of the first type of visitor are higher than those of the second type of visitor.

[0048] It should be noted that the visitor types mentioned above can be set according to actual needs. For example, in some embodiments, the administrator (equipment manufacturer or holder of the central device) can define users other than family members as visitors; in other embodiments, the administrator can divide visitors into first-class visitors and second-class visitors. First-class visitors may refer to close relatives, acquaintances, and other visitors with relatively close relationships, while second-class visitors may refer to unfamiliar friends, on-site repair personnel, property management personnel, and other temporary visitors. First-class visitors have higher operation permissions than second-class visitors; in other embodiments, the administrator can also divide visitors into first-level visitors, second-level visitors, and third-level visitors, and set corresponding operation permissions for each level of visitors; in other embodiments, the administrator can also divide visitor types in other ways. This application does not limit the specific method by which the administrator divides visitor types.

[0049] In one possible implementation of the first aspect, the visitor mode includes a first visitor mode and a second visitor mode;

[0050] The step of entering visitor mode when the user identity includes the visitor, and instructing the controllable device to enter visitor mode, includes:

[0051] When the user identity includes the first type of visitor but does not include the second type of visitor, the system enters the first visitor mode and instructs the controllable device to enter the first visitor mode.

[0052] When the user identity includes the second type of visitor, the system enters the second visitor mode and instructs the controllable device to enter the second visitor mode.

[0053] It should be noted that when the above visitors include both the first type of visitors and the second type of visitors, the above visitor patterns can include both the first visitor pattern and the second visitor pattern.

[0054] When a user's identity includes the first type of visitor but excludes the second type of visitor, the central device can control the central device and controllable devices to enter the first visitor mode with higher operating privileges.

[0055] When the user identity includes a second type of visitor, regardless of whether there is a first type of visitor in the home area, the central device can control the central device and the visitor device to enter the second visitor mode with lower operating permissions.

[0056] Using the above methods, the central device can manage different types of visitors more flexibly, provide different permissions to different types of visitors, prevent low-privilege visitors from stealing the operation permissions of high-privilege visitors, and protect the privacy, safety and property of family members.

[0057] In one possible implementation of the first aspect, after entering the second guest mode and instructing the controllable device to enter the second guest mode, the method further includes:

[0058] When a family member's exit operation is detected, the system enters family member mode and instructs the controllable device to enter family member mode.

[0059] Alternatively, when a family member's logout operation is detected, the system enters the first guest mode and instructs the controllable device to enter the first guest mode.

[0060] It should be noted that when the central device is in second visitor mode and the central device detects a family member's exit operation, the central device can control the central device and controllable devices to directly enter home mode.

[0061] However, if the central device directly controls the central device and controllable devices to enter the family member mode, the visitor may steal the family member's permissions, and unauthorizedly view the family member's private information and / or perform sensitive operations.

[0062] Therefore, when the central device is in the second visitor mode and the central device detects a family member's exit operation, the central device can also control the central device and controllable devices to enter the first visitor mode. This can satisfy the user's need to increase the visitor's privileges, and also prevent the visitor from using the family member's privileges without authorization in the family member mode, thereby protecting the privacy and personal and property safety of family members.

[0063] In one possible implementation of the first aspect, after entering visitor mode when the user includes the visitor, the method further includes:

[0064] Display the authorization code, which is used to request guest access from the target device, which is a family member's personal device.

[0065] It should be noted that in some scenarios, visitors may want to use their own personal devices to control electronic devices in the home area.

[0066] At this point, the central device can display an authorization code on the screen. This authorization code is used to request guest access from the target device, which is a family member's personal device.

[0067] After a visitor scans the authorization code using their visitor device (i.e., the visitor's personal device), the visitor device can send an authorization request to the target device.

[0068] When the target device agrees to the above authorization request, the guest device can obtain guest permissions.

[0069] When the target device rejects the above authorization request, the guest device cannot obtain guest permissions.

[0070] In one possible implementation of the first aspect, the sensitive operations include home management operations and / or control operations on electronic devices with security functions.

[0071] It should be noted that sensitive operations refer to operations that may affect the personal safety and property security of family members.

[0072] Specifically, sensitive operations may include any one or more of the following: home management operations, control operations of security equipment, etc.

[0073] Among these, family management operations refer to operations such as changing family information, sharing permissions, and changing permissions. Security equipment refers to electronic devices with security functions.

[0074] In one possible implementation of the first aspect, obtaining the user's identity includes:

[0075] The user's user characteristics are obtained, and the user characteristics are compared with pre-stored characteristics to determine the user's identity;

[0076] And / or, receive detection results sent by the detection device, and determine the user's identity based on the detection results, wherein the detection device is an electronic device with the function of detecting user identity.

[0077] It should be noted that after detecting user characteristics, the detection device can directly send those user characteristics to the central device.

[0078] After receiving user characteristics, the central device can compare the user characteristics with pre-stored characteristics to determine the user's identity.

[0079] Pre-stored features refer to pre-stored family information. This family information is used to distinguish between family members and visitors. This family information may include one or more of the following: administrator password, family member facial information, family member fingerprint data, family member voiceprint data, and the number of family members.

[0080] Alternatively, the detection device can process user characteristics locally to obtain detection results. Then, the detection device sends the detection results to the central device.

[0081] When the central device receives the detection results, it can determine the user's identity based on the detection results.

[0082] In one possible implementation of the first aspect, when the user characteristics include the number of users and the pre-stored characteristics include the number of household members, the step of obtaining the user characteristics of the user, comparing the user characteristics with the pre-stored characteristics, and determining the user's identity includes:

[0083] Compare the number of users with the number of family members;

[0084] If the number of users is greater than the number of family members, then the user's identity is determined to include a visitor.

[0085] It should be noted that the above user characteristics may include the number of users, and the above pre-stored characteristics may include the number of family members.

[0086] When the central device obtains the number of users, it can compare the number of users with the number of household members.

[0087] If the number of users is less than or equal to the number of household members, it means there may be no visitors in the household area.

[0088] If the number of users is greater than the number of people in the household, it means that there are visitors in the household area, and the central device can determine that the users mentioned above include visitors.

[0089] In one possible implementation of the first aspect, the number of family members is determined based on the number of people staying overnight in the family area each day during a historical period.

[0090] It should be noted that the above-mentioned number of family members can be determined by the central equipment based on the number of people staying overnight in the family area each day during a historical period.

[0091] For example, assuming the historical time period is the most recent week, if the central device detects that the mode of the number of people staying overnight each day during the most recent week is 3, then the central device can determine the number of family members as 3.

[0092] Secondly, embodiments of this application provide a device control apparatus applied to a central device, comprising:

[0093] The identity acquisition module is used to acquire the user's identity when a user is present in the home area; the user identity includes family members and / or visitors;

[0094] The visitor protection module is used to enter visitor mode when the user identity includes the visitor, and to instruct the controllable device to enter the visitor mode, and / or to assist the silent device in protecting privacy information and / or restricting sensitive operations;

[0095] The controllable device is an electronic device that supports guest mode, which is used to protect privacy information and / or restrict sensitive operations. The silent device is an electronic device that does not support guest mode.

[0098] In one possible implementation of the second aspect, the auxiliary silence device protects privacy information and / or restricts sensitive operations by including one or more of the following operations:

[0099] When a sensitive message is received destined for the silent device, the sensitive message is anonymized to obtain an anonymous message, and the anonymous message is forwarded to the silent device. The sensitive message includes the privacy information.

[0100] When a sensitive message is received destined for the silent device, the sensitive message is intercepted;

[0101] When a device control command is received from the silent device, the device control command is intercepted, and / or the operation corresponding to the device control command is prohibited from being executed.

[0102] In one possible implementation of the second aspect, the apparatus further includes:

[0106] In one possible implementation of the second aspect, the visitors include a first type of visitor and a second type of visitor, wherein the operation permissions of the first type of visitor are higher than those of the second type of visitor.

[0107] In one possible implementation of the second aspect, the visitor mode includes a first visitor mode and a second visitor mode;

[0108] The visitor protection module includes:

[0109] The first submodule is used to enter the first visitor mode when the user identity includes the first type of visitor and does not include the second type of visitor, and to instruct the controllable device to enter the first visitor mode;

[0110] The second submodule is used to enter the second visitor mode when the user identity includes the second type of visitor, and to instruct the controllable device to enter the second visitor mode.

[0111] In one possible implementation of the second aspect, the apparatus further includes:

[0112] The mode switching module is used to enter the family member mode when a family member's exit operation is detected, and to instruct the controllable device to enter the family member mode.

[0113] Alternatively, the mode switching module is used to enter the first visitor mode when a family member's exit operation is detected, and to instruct the controllable device to enter the first visitor mode.

[0114] In one possible implementation of the second aspect, the apparatus further includes:

[0115] An authorization display module is used to display an authorization code, which is used to request visitor permissions from a target device, which is a family member's personal device.

[0116] In one possible implementation of the second aspect, the sensitive operations include home management operations and / or control operations on electronic devices with security functions.

[0117] In one possible implementation of the second aspect, the identity acquisition module is used to acquire the user's user characteristics, compare the user characteristics with pre-stored characteristics, and determine the user's user identity.

[0118] And / or, the identity acquisition module is used to receive the detection result sent by the detection device and determine the user's identity based on the detection result, wherein the detection device is an electronic device with the function of detecting user identity.

[0119] In one possible implementation of the second aspect, when the user characteristics include the number of users and the pre-stored characteristics include the number of household members, the identity acquisition module includes:

[0120] The comparison submodule is used to compare the number of users with the number of family members;

[0121] The determination submodule is used to determine whether the user's identity includes a visitor if the number of users is greater than the number of family members.

[0122] In one possible implementation of the second aspect, the number of family members is determined based on the number of people staying overnight in the family area each day during a historical period.

[0153] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of this application. However, those skilled in the art will understand that this application may also be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods have been omitted so as not to obscure the description of this application with unnecessary detail.

[0154] It should be understood that, when used in this application specification and the appended claims, the term "comprising" indicates the presence of the described features, integrals, steps, operations, elements and / or components, but does not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components and / or a collection thereof.

[0155] It should also be understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0156] As used in this application specification and the appended claims, the term "if" may be interpreted, depending on the context, as "when," "once," "in response to determination," or "in response to detection." Similarly, the phrase "if determined" or "if detected [the described condition or event]" may be interpreted, depending on the context, as meaning "once determined," "in response to determination," "once detected [the described condition or event]," or "in response to detection [the described condition or event]."

[0157] Furthermore, in the description of this application and the appended claims, the terms "first," "second," "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0158] References to "one embodiment" or "some embodiments" as described in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0159] With the development of technology, more and more electronic devices have entered households, improving people's quality of life.

[0160] Among these electronic devices, some may record users' private information, while others may involve users' personal safety and property security.

[0161] For example, smart speakers may record users' listening history, favorite artists, and favorite songs; smart screens may record users' messages, viewing history, and favorite actors; thus, smart speakers and smart screens can make personalized recommendations based on this information, suggesting songs or movies that match the user's preferences; security devices such as cameras, smart door locks, and video doorbells (i.e., electronic devices with security functions) can monitor for unauthorized intrusions.

[0162] However, the electronic devices described above are usually unprotected against visitors. Therefore, when there are unfamiliar visitors in the home, they can freely view the user's private information on these electronic devices and / or operate security equipment without authorization, posing a serious threat to the user's privacy, personal safety, and property security.

[0163] For example, in some scenarios, when unfamiliar friends visit a home and the user and friend watch on a smart screen, the smart screen may make personalized recommendations based on the user's viewing preferences, making the user feel embarrassed. In other scenarios, when repairmen come to repair a home, they may take advantage of the user's inattention to turn off security devices such as cameras and steal the user's belongings, causing the user to suffer financial losses.

[0164] In view of this, the present application provides a device control method in which the central device can control each smart home device in the local area network to enter visitor mode when a visitor is detected, thereby protecting the user's privacy and personal and property safety, and has strong ease of use and practicality.

Electronic device 200 can also calculate the touch position based on the detection signal from pressure sensor 280A. In some embodiments, touch operations applied to the same touch position but with different touch operation intensities can correspond to different operation commands. For example, when a touch operation with an intensity less than a first pressure threshold is applied to the SMS application icon, a command to view an SMS is executed. When a touch operation with an intensity greater than or equal to the first pressure threshold is applied to the SMS application icon, a command to create a new SMS is executed.

For example, such as... Figure 3 As shown, assuming that the user's mobile phone 31 and the central device 32 are logged into the same IoT account, after the user records the voiceprint data of a family member through the microphone on the mobile phone 31, the mobile phone 31 can synchronize the voiceprint data to the central device 32 under the same IoT account through the IoT server 33 in the cloud.

[0234] In other embodiments, the aforementioned family information may also be obtained by the central device based on historical data analysis. For example, the central device can determine the family size based on the number of people staying overnight each day within a historical time period. Taking a specific scenario as an example, assuming the historical time period is the most recent week, if the central device detects that the mode of the number of people staying overnight each day within the most recent week is 3, then the central device can determine the family size to be 3.

[0235] In other embodiments, the central device may also input family information through other means. This application does not limit the specific method by which the central device inputs family information.

[0236] 2. Identify user identity.

[0237] Among the aforementioned smart home devices and central control devices, some electronic devices possess the function of detecting user identity. In the following description, these electronic devices with detection capabilities can be defined as detection devices.

[0238] The aforementioned detection equipment may include one or more electronic devices such as cameras, video doorbells, smart door locks, millimeter-wave radar, motion sensors, presence sensors, and smart speakers.

[0239] During operation, the detection equipment can collect user characteristics of each user within a residential area.

[0240] The aforementioned user characteristics are used to identify users, and user identities may include family members and visitors. These user characteristics may include one or more types of feature data, such as facial information, fingerprint data, access control passwords, sensor data, and voiceprint data.

[0241] After collecting user characteristics, the detection device can process these characteristics locally to identify the user's identity. The detection device can then send the detection results to the central device. These results may include one or more pieces of information such as user identity and the presence of visitors in the home area. Upon receiving these results, the central device can determine whether visitors are present in the home area.

[0242] And / or, after collecting user characteristics, the detection device can also directly send the user characteristics to the central device. After receiving the user characteristics, the central device processes the user characteristics, identifies the user identity corresponding to the user characteristics, and determines whether there are visitors in the home area based on the user identity.

[0243] For example, suppose the central device is a control screen and the detection device is a camera. After the camera captures facial information, it can locally identify the user's identity corresponding to that facial information and send that user identity to the control screen.

[0244] Alternatively, after the camera captures facial information, it can directly send the facial information to the central control screen. After receiving the facial information, the central control screen can identify the user identity corresponding to the facial information.

[0245] The method by which central devices / detection devices identify users can be set according to user characteristics and actual scenarios.

[0246] For example, please refer to Table 1, which schematically lists four ways to identify a user:

[0247] Table 1

[0248]

[0249] As shown in Table 1, the central device / detection device can identify the user identity corresponding to the user characteristics through methods such as face recognition, voiceprint recognition, password recognition, and number recognition.

[0250] When the central device / detection device uses facial recognition, it can match the user's facial information with pre-recorded facial information of family members. If the user's facial information matches a family member's facial information, the user is considered a family member. If the match fails, the user is considered a visitor.

[0251] When the central device / detection device uses voiceprint recognition, it can match the voiceprint data in the user's characteristics with the pre-recorded voiceprint data of family members. If the voiceprint data in the user's characteristics matches successfully with the voiceprint data of a family member, it indicates that the user corresponding to that voiceprint data is a family member. If the voiceprint data in the user's characteristics fails to match with the voiceprint data of a family member, it indicates that the user corresponding to that voiceprint data is a visitor.

[0252] When the central / detection device uses password recognition, it compares the user-entered password with the administrator password and a temporary password. The temporary password is assigned to the visitor by the administrator and may have access limits and / or time restrictions. For example, in some scenarios, the administrator can set the access limit for a temporary password to one, meaning it can only be used once and expires automatically. In other scenarios, the administrator can set the validity period for a temporary password to 10 minutes, meaning the visitor can only use it within that time, after which it automatically expires. If the password to be verified is the administrator password, it indicates that the user may be a family member. If the password to be verified is a temporary password, it indicates that the user is a visitor, and a visitor is present in the home area.

[0253] When the central device / detection device uses people recognition, the aforementioned user characteristics include the number of users in the current household area. The central device / detection device can compare the number of users with the number of household members. If the number of users is less than or equal to the number of household members, it indicates that there may be no visitors in the household area. If the number of users is greater than the number of household members, it indicates that there are visitors in the household area.

[0254] The examples above illustrate four methods for identifying user identities. In practical applications, the central device / detection device may employ the identification methods described above, and / or other undescribed identification methods. This application does not limit the specific method used by the central device / detection device to identify user identities.

[0255] Furthermore, the types of visitors mentioned above can be set according to actual needs. For example, in some embodiments, the administrator (equipment manufacturer or holder of the central device) can define users other than family members as visitors; in other embodiments, the administrator can divide visitors into trusted visitors and temporary visitors, where trusted visitors are relatives, acquaintances, or other close friends, and temporary visitors are unfamiliar friends, on-site repair personnel, property management personnel, or other visitors who come temporarily; in other embodiments, the administrator can also divide visitors into level one visitors, level two visitors, and level three visitors, and set corresponding permissions for each level of visitors; in other embodiments, the administrator can also divide visitor types in other ways. This application does not limit the specific method by which the administrator divides visitor types.

[0256] It should be noted that, given the various ways visitor types can be represented, the following descriptions will use "trusted visitors" and "temporary visitors" as illustrative examples. It is understood that, unless otherwise specified, the following descriptions also apply to other methods of visitor type classification.

[0257] 3. Enter guest mode.

[0258] When the central device determines that there is a visitor in the home area, the central device can enter visitor mode and send visitor mode notifications to various smart home devices in the local area network.

[0259] When a smart home device receives a guest mode notification, it can enter guest mode.

[0260] In guest mode, electronic devices can protect the privacy of family members and / or restrict sensitive operations. Sensitive operations refer to operations that involve the personal safety and property of family members, such as controlling security devices or changing family information.

[0261] Specifically, electronic devices can protect privacy information and restrict sensitive operations through one or more of the following protection strategies: anonymizing privacy information, hiding privacy information, hiding access points to privacy information, blocking sensitive operations, hiding access points to sensitive operations, and performing authentication when sensitive operations are detected.

[0262] For example, please refer to Table 2, which lists four protection strategies for protected objects.

[0263] Table 2

[0264]

[0265] As shown in Table 2, in Family Member Mode, electronic devices can display voice messages, text messages, and other communication content normally. In Guest Mode, electronic devices can anonymize this communication content, prompting the user to view it on their personal device. Personal devices can refer to non-shared electronic devices such as mobile phones and smart wearable devices.

[0266] For example, when a smart speaker is in guest mode, if it receives a voice message, it can announce, "You have a new voice message. Please view it on your phone." This prompts family members to listen to the voice message on their phones, avoiding the smart speaker directly broadcasting the voice message in front of guests and causing embarrassment to family members.

[0267] In Family Member Mode, electronic devices can play and recommend audio and video content to family members based on their playback history, favorite music / artists, and preferred video genres / actors. In Guest Mode, playback history can be hidden, and audio and video content will not be played or recommended based on playback history or personal preferences.

[0268] For example, suppose a family member enjoys watching cartoons on the smart screen. In family member mode, the smart screen can recommend cartoons to that family member based on their viewing history and personal preferences. In guest mode, the smart screen can hide the viewing history and randomly recommend videos to avoid letting guests know that a family member enjoys watching cartoons.

[0269] For sensitive operations such as operating security devices and changing family information, in Family Member Mode, the electronic device can display the access point for sensitive operations normally. Furthermore, in some scenarios, family members can directly perform sensitive operations without authentication. In Guest Mode, the electronic device can hide the access point for sensitive operations to prevent visitors from performing them. Alternatively, the electronic device can require user authentication when a sensitive operation is detected. Authentication can include one or more methods such as facial recognition, fingerprint verification, voiceprint verification, and password verification. If authentication is successful, it indicates that a family member is performing the sensitive operation, and the electronic device can execute the sensitive operation; if authentication fails, it indicates that a non-family member is performing the sensitive operation, and the electronic device can refuse to execute the sensitive operation.

[0270] For example, please refer to Figure 4 and Figure 5 Assume the central device is the central control screen 41, and the security equipment includes cameras 42.

[0271] like Figure 5As shown in scenario (a), the camera control interface 410 of the central control screen 41 includes a monitoring display interface 411, a pan-tilt left control 412, a pan-tilt right control 413, a pan-tilt up control 414, a pan-tilt down control 415, and a switch control 416. In family member mode, when the camera 42 is on, when the central control screen 41 detects a user's click on the switch control 416, the central control screen 41 can directly send a shutdown command to the camera 42.

[0272] like Figure 5 As shown in scenario (b) in the example, in guest mode, when camera 42 is on, and the central control screen 41 detects a user's click on switch control 416, the central control screen 41 can pop up an authentication box 417 and a virtual keyboard 418. Then, in response to the user's operation on the virtual keyboard 418, the central control screen 41 can obtain the password to be verified and compare it with the administrator password. If the password to be verified matches the administrator password, authentication is successful, and the central control screen 41 can send a shutdown command to camera 42. If the password to be verified does not match the administrator password, authentication fails, and the central control screen 41 may not respond to the user's click on switch control 416.

[0273] For private information such as family photo albums, delivery addresses, and phone numbers, in family member mode, the electronic device can display access to this information normally, and users can also edit this information. In guest mode, the electronic device can still display access to this information; however, when the device detects a user editing the information, it can require user authentication. If authentication is successful, the device allows the user to edit the information; if authentication fails, the device can refuse the user's editing. Alternatively, the electronic device can hide access to this information to prevent guests from viewing family members' private information.

[0274] For example, such as Figure 6 As shown in scenario (a), assume that the homepage of the smart screen includes channel program control 601, application software control 602, cloud space control 603, and system settings control 604.

[0275] In family member mode, the smart screen can normally display four controls: channel program control 601, application software control 602, cloud space control 603, and system settings control 604. When the smart screen detects a user's selection of the cloud space control 603, the smart screen can access the cloud space interface. Figure 6 As shown in scenario (b), the smart screen can display photos, documents, videos and other content in the cloud space to users in the cloud space access interface.

[0276] like Figure 7 As shown, in guest mode, the smart screen's homepage can directly hide the cloud space control 603. At this time, users cannot access the cloud space interface or view its content.

[0277] The above schematically illustrates the protection strategies of electronic devices for the four types of protected objects. In practical application scenarios, the aforementioned privacy information and sensitive operations may include the four types of protected objects, and / or may include other protected objects not shown. Furthermore, when protecting privacy information and restricting sensitive operations, electronic devices may employ the protection strategies shown above, and / or may employ other protection strategies not shown. This application embodiment does not limit the objects protected by the electronic device in guest mode or the protection strategies adopted.

[0278] Furthermore, when different types of visitors exist, different visitor types can correspond to different visitor modes. Different visitor modes can employ different protection strategies. In this case, the central device can control the central device and smart home devices to enter the corresponding visitor mode based on the identified visitor type.

[0279] For example, such as Figure 8 As shown, assuming the central device is the central control screen, visitor types include trusted visitors and temporary visitors.

[0280] When the central control screen determines that there are trusted visitors within the home area and no temporary visitors, the central control screen can enter trusted visitor mode. For example... Figure 8 As shown in scenario (a), in trusted visitor mode, the main interface 801 of the central control screen may include basic device controls 81, security device controls 82, scenario setting controls 83, and system setting controls 84. For example... Figure 8 As shown in scenario (b), when the central control screen detects a user's click on the security device control 82, the central control screen can pop up an authentication box 85 and a virtual keyboard 86. Then, in response to the user's operation on the virtual keyboard 86, the central control screen can obtain the password to be verified and compare it with the administrator password. Figure 9 As shown, if the password to be verified matches the administrator's password, authentication is successful, and the central control screen can access the security device control interface 802. At this time, the user can control the security devices displayed on the interface, such as cameras, smoke detectors, and biometric sensors. If the password to be verified does not match the administrator's password, authentication fails, and the central control screen may not respond to user clicks on the security device controls.

[0281] like Figure 10As shown, when the central control screen determines that there is a temporary visitor in the home area, the central control screen can enter the temporary visitor mode, and the central control screen can hide the security device control 82 on the main interface 801. At this time, the main interface 801 of the central control screen can include the basic device control 81, the scene setting control 83, and the system setting control 84, but does not include the security device control 82. The user cannot find the security device control 82 and cannot enter the security device control interface 802.

[0282] In the examples described above, different visitor types correspond to different visitor modes, and the central device can determine the corresponding visitor mode based on the identified visitor type. In this way, the central device can manage different types of visitors more flexibly and provide different permissions to different types of visitors.

[0283] Furthermore, when the central device detects visitors of different visitor types within the home area, it can determine the target visitor type with the lowest privileges from among these visitor types and enter the visitor mode corresponding to that target visitor type. For example, suppose a trusted visitor has higher privileges than a temporary visitor. When the central device recognizes the presence of both trusted and temporary visitors in the home area, it can enter the temporary visitor mode instead of the trusted visitor mode. In this way, the central device can prevent visitors with lower privileges from using the privileges of other visitors to view family members' private information and / or perform sensitive operations beyond their authority, thus protecting the privacy, safety, and property security of family members.

[0284] 4. Personal device licensing.

[0285] In real-world applications, visitors may want to use their personal devices to control central devices / smart home devices within their home area.

[0286] At this point, electronic devices with displays (such as central devices and / or smart home devices) can display the authorization code on the screen. This authorization code can be displayed using any one or more forms, such as barcodes, QR codes, or RFID tags. After a visitor scans the authorization code using their personal device, the visitor device can send an authorization request to the target device. The target device refers to a personal device logged into the same IoT account as the central device, or it can be understood as a family member's personal device.

[0287] When the target device agrees to the above authorization request, the guest device can obtain guest permissions.

[0288] When the target device rejects the above authorization request, the guest device cannot obtain guest permissions.

[0289] The type of visitor permission can be related to the visitor mode currently in which the central device / smart home device is located.

[0290] For example, when the central device and smart home devices in the home area are in trusted visitor mode, the visitor device can obtain trusted visitor permissions after being authorized by the target device; when the central device and smart home devices in the home area are in temporary visitor mode, the visitor device can obtain temporary visitor permissions after being authorized by the target device.

[0291] Alternatively, the type of visitor permission mentioned above can also be set by the target device.

[0292] For example, such as Figure 11 As shown, assuming the target device is a mobile phone, when the mobile phone receives an authorization request, it can display an authorization consultation box 111. The authorization consultation box includes the text "Guest device requests guest permissions" and provides an "Agree" control 1111 and a "Deny" control 1112. When the mobile phone detects that the user clicks on the "Agree" control 1111, as shown... Figure 12 As shown, the phone can display a permission selection box 112. Permission selection box 112 includes two options: "Trusted Guest Permission" and "Temporary Guest Permission". When the phone detects a user's click on "Trusted Guest Permission", it can send a trusted guest authorization notification to the guest device. This trusted guest authorization notification is used to grant trusted guest permissions to the guest device.

[0293] Furthermore, when a guest device is granted different guest permissions, the guest device can have different operational scopes.

[0294] For example, please refer to Table 3, which schematically lists the operation scope corresponding to different permissions:

[0295] Table 3

[0296] Security control operation Privacy viewing operation Family management operation Basic equipment operation Family member permissions Fully controllable Fully controllable Fully controllable Fully controllable Trusted visitor permissions Authorization controllable Authorization controllable Completely uncontrollable Fully controllable Temporary visitor permissions Completely uncontrollable Completely uncontrollable Completely uncontrollable Authorization controllable

[0297] Among them, security control operations can include controlling security devices; privacy viewing operations can include viewing the privacy information of family members; family management operations can include changing family information, sharing permissions, changing permissions, etc.; basic device operations can include controlling low-risk smart home devices other than security control operations, privacy viewing operations, and family management operations, such as turning on the smart screen, turning on the air conditioner, controlling the robot vacuum cleaner, turning on / off smart lights, etc.

[0298] Fully controllable means that the target device / guest device can directly perform such operations; authorized controllable means that the guest device needs to request operation permission from the target device before performing such operations, and the guest device can perform such operations if the target device grants operation permission; completely uncontrollable means that the guest device is prohibited from performing such operations.

[0299] For the target device, if the target device has family member permissions, as shown in Table 3, then the target device can directly perform security control operations, privacy viewing operations, family management operations, and basic device operations.

[0300] For guest devices, if the guest device has trusted guest permissions, as shown in Table 3, the guest device can directly perform basic device operations; and, if the target device grants operation permissions, the guest device can also perform security control operations and privacy viewing operations.

[0301] For guest devices, if the guest device has temporary guest permissions, as shown in Table 3, the guest device can perform basic device operations, but is prohibited from performing security control operations and privacy viewing operations, provided that the target device grants operation permissions.

[0302] Furthermore, to prevent guest devices from stealing family members' permissions, guest devices are prohibited from performing family management operations regardless of the type of guest permissions they possess.

[0303] In addition to differences in the scope of operation, different visitor permissions may also have different usage restrictions.

[0304] For example, in some embodiments, trusted visitor permissions have no time limit, while temporary visitor permissions can only be used for a limited period of time; in other embodiments, trusted visitor permissions have no limit on the number of uses, while temporary visitor permissions can only be used a limited number of times; in still other embodiments, trusted visitor permissions have no network restrictions, and a visitor device with trusted visitor permissions can use the trusted visitor permissions to control the aforementioned smart home devices through a home LAN or WAN, while temporary visitor permissions can only be used when the visitor device is connected to the corresponding home LAN. When a visitor device with temporary visitor permissions leaves the home LAN, the visitor device cannot use the temporary visitor permissions and cannot control the aforementioned smart home devices.

[0305] Furthermore, it should be noted that the aforementioned visitor types and visitor permissions can be changed.

[0306] In some embodiments, the management device can respond to changes made by family members, modifying the visitor type and visitor permissions. A management device refers to an electronic device capable of performing family management operations, such as a central device or a family member's personal device.

[0307] In other embodiments, visitor type and visitor permissions can also be automatically changed according to pre-set change rules. These change rules can be related to factors such as the number of visits and the duration of stay. For example, as the number of visits increases, the visitor type can be automatically changed from a temporary visitor to a trusted visitor. This application does not limit the specific content of the change rules.

[0308] 5. To assist in anonymity and control.

[0309] Among the aforementioned smart home devices, some may not support guest mode. Therefore, these devices cannot respond to guest mode notifications from the central device and enter guest mode. In this application, smart home devices that do not support guest mode are referred to as "silent devices." Because silent devices cannot enter guest mode, they may potentially leak family members' privacy information and / or perform sensitive operations under the control of a visitor. To reduce the likelihood of such incidents, the central device can assist silent devices in protecting privacy information and restricting sensitive operations.

[0310] In some embodiments, if the central device detects privacy information sent to the silent device and is in guest mode at the time, the central device can anonymize the privacy information to obtain anonymous information and send the anonymous information to the silent device.

[0311] For example, such as Figure 13 As shown, assume the central device is the control screen 131 and the silent device is the smart speaker 132. At a certain moment, the IoT server 130 sends a voice message to the control screen 131, instructing the control screen 131 to forward the voice message to the smart speaker 132. At this time, the control screen 131 detects that the smart speaker 132 is a silent device and is currently in guest mode. Therefore, the control screen 131 can anonymize the voice message to obtain an anonymous message. Then, the control screen 131 can forward the anonymous message to the smart speaker 132. After receiving the anonymous message, the smart speaker 132 can directly announce the anonymous message: "You have received a new voice message. Please check it on your mobile phone." This avoids the leakage of family members' privacy information in guest mode.

[0312] In other embodiments, when the central device detects privacy information being sent to the silent device, the central device can directly intercept the privacy information.

[0313] For example, such as Figure 14As shown, assume the central device is the central control screen 141, the silent device is the smart screen 142, and the family member's personal device is the mobile phone 143. At a certain moment, family members and friends are watching a program played on the smart screen 142 together at home. At this time, the IoT server 140 sends a text message to the central control screen 141, instructing the central control screen 141 to forward the text message to the smart screen 142. After receiving the text message, the central control screen 141 detects that the smart screen 142 is a silent device, so the central control screen 141 can directly intercept the text message and forward it to the mobile phone 143. At this time, the smart screen 142 cannot receive or display the text message, but family members can view the text message through the mobile phone 143.

[0314] In other embodiments, when the central device detects a device control command sent by a silent device, the central device can directly intercept the device control command and prevent its execution. The aforementioned device control command is used to control the central device and / or smart home devices.

[0315] For example, such as Figure 15 As shown, assume the central device is the control panel 151 and the silent device is the smart speaker 152. At a certain moment, a visitor says to the smart speaker 152, "Hey, Hey, open the door." In response, the smart speaker 152 sends an open command to the control panel 151, instructing it to forward the command to the smart lock. When the control panel 151 receives the open command, it detects that the smart speaker 152 is a silent device, so it directly intercepts the command, does not forward it to the smart lock, and returns an operation failure message to the smart speaker 152. When the smart speaker 152 receives the operation failure message, it announces, "Operation failed, please try again."

[0316] In other embodiments, the central device may also assist the silent device in protecting privacy information and restricting sensitive operations in other ways. This application does not limit the specific assistance methods provided by the central device.

[0317] Through the above methods, the central device can assist the silent device in protecting privacy information and restricting sensitive operations, reducing the possibility of the silent device leaking privacy information and performing sensitive operations without authorization, thereby effectively protecting the privacy and personal and property safety of family members.

[0318] 6. Exit guest mode.

[0319] In addition to automatically controlling the entry of central devices and smart home devices into visitor mode, the central device can also control the exit of central devices and smart home devices from visitor mode. The conditions for the central device to control the exit of central devices and smart home devices from visitor mode can be set according to the actual scenario.

[0320] In some possible implementations, the central device can respond to a user's action by controlling both the central device and the smart home devices to exit guest mode after successful user authentication. For example, when the central device detects a user's exit action, it can authenticate the user. If authentication is successful (e.g., confirming the user performing the exit action is a family member), the central device can exit guest mode and send a guest mode exit notification to the smart home devices; upon receiving the notification, the smart home devices can exit guest mode. If authentication fails (e.g., confirming the user performing the exit action is a guest), the central device does not respond to the exit action.

[0321] In some embodiments, when it is determined that there are no visitors in the home area, the central device can respond to the user's operation and control the central device and smart home devices to directly exit the visitor mode and enter the family member mode.

[0322] For example, when a maintenance worker is in the home area, the central device and smart home devices are in visitor mode; after the maintenance worker leaves, the user logs out on the central device. At this time, the central device can determine whether a visitor is present in the home area through various detection devices.

[0323] When the central device determines that there are no visitors in the home area, it can respond to the above exit operation and control the central device and other smart home devices to directly exit the visitor mode and enter the family member mode.

[0324] In other embodiments, when there are still visitors in the home area, the central device can respond to the user's operation and control the central device and smart home devices to directly exit the visitor mode and enter the family member mode.

[0325] For example, suppose the central device sets the user's operation permissions to the highest priority.

[0326] At some point, the central device detects the user's logout action and determines that there are still visitors in the home area.

[0327] At this time, since the central device's operating authority is lower than the user's operating authority, even if there are visitors in the home area, the central device can respond to the user's operation and control the central device and smart home devices to directly exit the visitor mode and enter the family member mode.

[0328] In other embodiments, when there are still visitors in the home area, the central device can respond to the user's operation by controlling the central device and smart home devices to exit the current visitor mode and enter a higher-privilege visitor mode.

[0329] For example, as mentioned earlier, suppose visitor types are divided into trusted visitors and temporary visitors, where trusted visitors correspond to trusted visitor mode and temporary visitors correspond to temporary visitor mode, and the central device is currently in temporary visitor mode. At a certain moment, the central device detects a user's logout operation and determines that there are still two visitors residing in the home area, both of whom are temporary visitors. At this point, the central device can change the visitor type of these two visitors to trusted visitors, record their user characteristics in the trusted visitor feature database, exit temporary visitor mode, and enter trusted visitor mode.

[0330] It should be noted that when the central device detects an exit operation and determines that there is a visitor in the home area, if the central device directly enters the family member mode, the visitor may steal the family member's permissions and unauthorizedly view the family member's private information and / or perform sensitive operations.

[0331] Therefore, in this embodiment, when the central device detects an exit operation, if the central device determines that there is a visitor in the home area, the central device can control the central device and smart home devices to exit the current visitor mode and enter a higher-privilege visitor mode.

[0332] In this way, the central device can both meet the user's need to increase the permissions of guests and prevent guests from using the permissions of family members without authorization in the family member mode, thereby protecting the privacy and personal and property safety of family members.

[0333] In some other possible implementations, when the central device detects that every user in the home area is a family member, the central device can control the central device and smart home devices to exit guest mode.

[0334] For example, suppose at a certain moment, the central device detects that two visitors have left the home area, leaving only two users, both of whom are family members. In this case, the central device can control both the central device and the smart home devices to automatically exit visitor mode and enter family member mode.

[0335] In some other possible implementations, when the central device detects that all users have left the home area, the central device can control the central device and smart home devices to exit guest mode.

[0336] For example, suppose that at a certain moment, the central device detects that no user is present in the home area through the presence sensor. At this time, the central device can control the central device and smart home devices to automatically exit guest mode and enter family member mode.

[0337] In some other possible implementations, when the central device detects that all users have left the home area, the central device can remain in guest mode; thereafter, when the central device detects that a user has entered the home area and that user is a family member, the central device can control the central device and smart home devices to exit guest mode and enter family member mode.

[0338] For example, suppose that at a certain moment, the central device detects that no user is present in the home area using a presence sensor. At this time, the central device can remain in visitor mode. After a period of time, if the central device detects that a user has entered the home area using a camera, and the user's facial recognition results indicate that the user is a family member, then the central device can control the central device and smart home devices to automatically exit visitor mode and enter family member mode.

[0339] Using the above method, the central device can control the central device and each smart home device to exit guest mode, eliminating the need for users to operate each electronic device individually, reducing the amount of user work and improving the user experience.

[0340] To facilitate understanding, the above-mentioned device control methods will be explained in detail below in conjunction with specific application scenarios.

[0341] Please see Figure 16 Suppose that user A's home is equipped with a central control screen 161, a camera 162, a smart screen 163, and a smart speaker 164. Among them, the central control screen 161 is the central device, the camera 162, the smart screen 163, and the smart speaker 164 are smart home devices, and the smart speaker 164 is a silent device.

[0342] At the first moment, User A brings User B to his home as a guest. At this time, camera 162 captures User A's facial information 1 and User B's facial information 2, and sends facial information 1 and facial information 2 to the central control screen 161.

[0343] The central control screen 161 has pre-stored the facial information of family members and trusted visitors. Therefore, the central control screen 161 can compare facial information 1 and facial information 2 with the facial information of family members and trusted visitors to determine the user identities of user A and user B.

[0344] After determining that User A is a family member and User B is a temporary visitor, the central control screen 161 automatically enters temporary visitor mode and sends a first visitor mode notification to the camera 162 and the smart screen 163. In response to the first visitor mode notification, the camera 162 and the smart screen 163 automatically enter temporary visitor mode.

[0345] like Figure 17 As shown in scenario (a), suppose User B will be staying at User A's home for a few days. Therefore, to make it easier for User B to control various smart home devices, User A can operate the central control screen 161 and enter its settings interface 1611. The settings interface 1611 has four options: "Network Settings," "Desktop and Wallpaper," "Display and Brightness," and "Exit Current Mode." The user can click the "Exit Current Mode" option in the settings interface 1611.

[0346] At this time, as Figure 17 As shown in scenario (b), the central control screen 161 can respond to user A's operation by displaying an authentication box 1612 and a virtual keyboard 1613 on the settings interface 1611. Then, the central control screen 161 can respond to user A's operation on the virtual keyboard 1613, obtain the password to be verified, and compare the password to be verified with the administrator password.

[0347] Since the password entered by user A is the same as the administrator's password, the central control screen 161 exits the temporary visitor mode and enters the trusted visitor mode, sends a mode change notification to the camera 162 and the smart screen 163, and records user B's facial information in the trusted visitor feature database.

[0348] After receiving the mode change notification, camera 162 and smart screen 163 exit the temporary visitor mode and enter the trusted visitor mode.

[0349] And, as Figure 18 As shown in scenario (a), user A can also operate the central control screen 161 and enter the main interface 1614 of the central control screen. The main interface 1614 includes a "music" control 1615, a "device control" control 1616, a "weather" control 1617, an "authorization code" control 1618, a "building intercom" control 1619, and a "settings" control 1620.

[0350] User A can click the "Authorization Code" control 1618 on the main interface 1614.

[0351] At this time, as Figure 18 As shown in scenario (b), the central control screen 161 responds to the user's operation and enters the authorization code interface 1621, which includes authorization code 1622.

[0352] like Figure 19 As shown, after User B scans the authorization code using Mobile Phone 165 (User B's personal device), Mobile Phone 165 can send an authorization request to IoT Server 166. After receiving the authorization request, IoT Server 166 forwards the authorization request to User A's Mobile Phone 167 (User A's personal device).

[0353] like Figure 20 As shown in scenario (a), after receiving the authorization request, mobile phone 167 displays an authorization consultation box 1623 on its screen. The authorization consultation box 1623 includes the text "Mobile phone 165 requests guest permission" and provides an "Agree" control 1624 and a "Deny" control 1625. When user A clicks the "Agree" control 1624 on the screen of mobile phone 167, as shown in scenario (a),... Figure 20 As shown in scenario (b), mobile phone 167 can display a permission selection box 1626. The permission selection box 1626 includes two options: "Trusted Guest Permission" and "Temporary Guest Permission".

[0354] When user A clicks "Trusted Guest Permission" on the screen of mobile phone 167, mobile phone 167 sends a trusted guest authorization notification to IoT server 166. After receiving the trusted guest authorization notification, IoT server 166 forwards the trusted guest authorization notification to mobile phone 165 and records the device identifier of mobile phone 165 in the trusted guest permission device list.

[0355] After receiving the trusted visitor authorization notification, mobile phone 165 obtains trusted visitor permissions. At this time, user B can directly perform basic device operations on mobile phone 165. Furthermore, with authorization from mobile phone 167, user B can also perform security control operations and privacy viewing operations on mobile phone 165.

[0356] like Figure 21 As shown, at the second moment, the IoT server 166 sends a voice message to the central control screen 161, instructing the central control screen 161 to forward the voice message to the smart speaker 164. Since the central control screen 161 is in trusted guest mode and the smart speaker 164 is a silent device, the central control screen 161 intercepts the voice message and forwards it to the mobile phone 167. After receiving the voice message, the mobile phone 167 vibrates to notify user A that a voice message has been received. At this time, user A can listen to the voice message on the mobile phone 167.

[0357] At the third moment, User B left User A's home, and the central control screen 161 detected that the facial information sent by camera 162 only contained User A's facial information. Therefore, the central control screen 161 exited the trusted visitor mode, entered the family member mode, and sent a family mode notification to camera 162 and smart screen 163. After receiving the family mode notification, camera 162 and smart screen 163 exited the trusted visitor mode and entered the family member mode.

[0358] At the fourth moment, User B returned to User A's home. Camera 162 detected User B's facial information and sent it to the central control screen 161. Since the central control screen 161's trusted visitor feature database contains User B's facial information, it can determine that User B is a trusted visitor. At this point, the central control screen 161 enters trusted visitor mode and sends a second visitor mode notification to Camera 162 and the smart screen 163. Upon receiving the second visitor mode notification, Camera 162 and the smart screen 163 also enter trusted visitor mode.

[0359] As can be seen from the methods and examples described above, in the device control method provided in the embodiments of this application, the central device can automatically control the central device and smart home devices to enter visitor mode when it is confirmed that there are visitors in the home area, so as to protect the privacy information of family members and restrict sensitive operations, thereby protecting the user's privacy and personal and property safety.

[0360] Furthermore, when administrators set up multiple different visitor types, each visitor type can correspond to a different visitor mode, and each visitor mode can employ different protection strategies. The central device can flexibly manage different types of visitors and provide different permissions to different types of visitors by managing visitor modes.

[0361] Furthermore, when a visitor wishes to control the central device / smart home devices using a visitor device, the visitor device can send an authorization request by scanning an authorization code. When the target device agrees to the authorization request, the visitor device gains visitor permissions. Different visitor permissions have different operational scopes. Therefore, by managing visitor permissions, the management device can both meet the visitor's need to control the central device / smart home devices and prevent visitors from unauthorizedly viewing family members' private information or performing sensitive operations.

[0362] For silent devices that do not support guest mode, the central device can assist silent devices in protecting privacy information and restricting sensitive operations, thereby reducing the possibility of silent devices leaking privacy information and performing sensitive operations without authorization.

[0363] In addition to automatically controlling the central device and smart home devices to enter visitor mode, the central device can also control the central device and smart home devices to exit visitor mode when the conditions for exiting visitor mode are met. This eliminates the need for users to operate each electronic device individually, reducing the amount of user work and improving the user experience.

[0364] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.

[0365] The following will describe in detail another device control method provided in the embodiments of this application from the perspective of a central device. Please refer to... Figure 22 The device control method provided in this embodiment includes:

[0366] S221. When a user is present in the home area, obtain the user's identity; the user's identity includes family members and / or visitors.

[0367] It should be noted that when a user is present in the home area, the central device can obtain the user's identity. The user's identity can include family members and / or visitors.

[0368] In the process of identifying a user, the detection device can detect the user's characteristics. These user characteristics may include one or more types of feature data such as facial information, fingerprint data, access control passwords, sensor data, and voiceprint data.

[0369] After detecting user characteristics, the detection equipment can directly send the user characteristics to the central device.

[0370] After acquiring user characteristics, the central device can compare these characteristics with pre-stored characteristics to determine the user's device.

[0371] Pre-stored features refer to pre-stored family information. This family information is used to distinguish between family members and visitors. This family information may include one or more of the following: administrator password, family member facial information, family member fingerprint data, family member voiceprint data, and the number of family members.

[0372] Alternatively, the detection device can process user characteristics locally to obtain detection results. Then, the detection device can send the detection results to the central device.

[0373] When the central device receives the detection results, it can determine the user's identity based on the detection results.

[0374] S222. When the above user identity includes the above visitor, enter visitor mode and instruct the controllable device to enter the above visitor mode, and / or assist the silent device in protecting privacy information and / or restricting sensitive operations.

[0375] The aforementioned controllable devices are electronic devices that support guest mode. The guest mode is used to protect privacy information and / or restrict sensitive operations. The aforementioned silent devices are electronic devices that do not support guest mode.

[0376] It should be noted that after obtaining the user's identity, the central device can identify whether there are any visitors among the aforementioned user identities.

[0377] If the user identity mentioned above includes "visitor," it indicates that a visitor has entered the home area. In this case, to prevent the visitor from viewing family members' private information or performing sensitive operations without authorization, the central device can enter visitor mode, and instruct controllable devices to enter visitor mode as well.

[0378] Controllable devices refer to electronic devices that support guest mode. Guest mode is used to protect privacy information and / or restrict sensitive operations.

[0379] Furthermore, for silent devices that do not support guest mode, the central device can assist silent devices in protecting privacy information and / or restricting sensitive operations.

[0380] By employing the methods described above, the central device can prevent visitors from arbitrarily viewing family members' private information or performing sensitive operations without authorization. This effectively reduces the possibility of privacy leaks and unauthorized operations, protecting users' privacy, personal safety, and property security. It is highly practical and easy to use.

[0381] Optionally, the above visitor mode includes one or more of the following operations:

[0382] The above-mentioned privacy information is anonymized, hidden, and access points to the above-mentioned privacy information are hidden. The execution of the above-mentioned sensitive operations is prohibited, access points to the above-mentioned sensitive operations are hidden, and identity verification is performed when the above-mentioned sensitive operations are detected.

[0383] It should be noted that in guest mode, electronic devices can protect privacy information and restrict sensitive operations through one or more of the following protection strategies: anonymizing privacy information, hiding privacy information, hiding access points to privacy information, blocking sensitive operations, hiding access points to sensitive operations, and performing authentication when sensitive operations are detected.

[0384] For example, in some cases, when an electronic device receives a voice message in guest mode, the device can anonymize the voice message and announce, "You have a new voice message. Please view it on your personal device," thereby hiding the details of the private information and prompting family members to check the voice message on their personal devices.

[0385] In other examples, when an electronic device enters guest mode, it can directly hide private information such as photo albums and contacts, or hide access points to this private information.

[0386] In other examples, when an electronic device enters guest mode, if the electronic device detects a sensitive operation, it can block that sensitive operation and not respond to it.

[0387] In other examples, when an electronic device enters guest mode, it can directly hide the access point for sensitive operations, thus preventing users from accessing the interface for sensitive operations and performing sensitive actions.

[0388] In other examples, when an electronic device enters guest mode, it can authenticate the user if it detects a sensitive action.

[0389] If authentication is successful, it indicates that the user performing the sensitive operation is a family member, and the electronic device can respond to the sensitive operation; if authentication fails, it indicates that the user performing the sensitive operation is not a family member, and the electronic device may not respond to the sensitive operation.

[0390] In other examples, electronic devices may employ other protection strategies to protect privacy information and restrict sensitive operations. This application does not limit the protection strategies adopted by electronic devices.

[0391] Optionally, the aforementioned auxiliary silence device protects privacy information and / or restricts sensitive operations by including one or more of the following operations:

[0392] When a sensitive message is received that is sent to the aforementioned silent device, the sensitive message is anonymized to obtain an anonymous message, and the anonymous message is forwarded to the aforementioned silent device. The sensitive message includes the aforementioned privacy information.

[0393] When a sensitive message is received destined for the aforementioned silent device, the sensitive message is intercepted.

[0394] When a device control command is received from the aforementioned silent device, the device control command is intercepted, and / or the operation corresponding to the aforementioned device control command is prohibited.

[0395] It should be noted that when the central device assists the silent device in protecting privacy information and / or restricting sensitive operations, it can select an appropriate assistance method based on the actual scenario.

[0396] For example, in some cases, when the central device receives a sensitive message destined for a silent device, because the sensitive message contains private information, the central device can anonymize the message, hiding the private information within it, thus obtaining an anonymous message. The central device then forwards the anonymous message to the silent device, reducing the likelihood of the silent device leaking the private information of family members.

[0397] In other examples, when the central device receives a sensitive message destined for a silent device, the central device can also directly intercept the sensitive message and forward it to the personal device of a family member, thereby protecting the privacy information of the family member.

[0398] In other examples, when the central device receives a device control command from the silent device, if the command is intended to control other electronic devices, the central device can directly intercept it; if the command is intended to control the central device, the central device can choose not to respond. By intercepting and / or disabling the execution of device control commands, the central device can reduce the likelihood of visitors performing sensitive operations through the silent device.

[0399] In other examples, the central device may also assist the silent device in protecting privacy information and / or restricting sensitive operations through other auxiliary methods. This application does not limit the specific form of the aforementioned auxiliary methods.

[0400] Optionally, after entering guest mode when the user identity includes the visitor, and instructing the controllable device to enter guest mode, and / or assisting the silent device in protecting privacy information and / or restricting sensitive operations, the following steps are included:

[0401] When the preset exit conditions are met, exit the above guest mode and instruct the above controllable device to exit the above guest mode, and / or, no longer assist the above silent device in protecting privacy information and / or restricting sensitive operations.

[0402] It should be noted that when the preset exit conditions are met, the central device can control the central device and controllable devices to automatically exit the guest mode, and stop assisting the aforementioned silent devices in protecting privacy information and / or restricting sensitive operations. This eliminates the need for users to operate each electronic device individually, reducing the amount of user work and improving the user experience.

[0403] Optionally, the above-mentioned preset exit conditions include one or more of the following conditions:

[0404] A family member's logout was detected; no users are present in the family area; no visitors are present in the family area.

[0405] It should be noted that the preset exit conditions can be set according to actual needs. For example, in some examples, the preset exit condition can be the detection of a family member's exit operation. In this case, when the central device detects an exit operation, it can authenticate the user. If authentication is successful, the central device can respond to the exit operation; if authentication fails, the central device will not respond to the exit operation.

[0406] In other examples, the preset exit condition can be the absence of users in the home area. In this case, when the central device determines that all users have left the home area, the central device can control the central device and each controllable device to automatically exit guest mode, and to stop assisting the aforementioned silent devices in protecting privacy information and / or restricting sensitive operations.

[0407] In other examples, the preset exit condition can be the absence of visitors in the home area. In this case, when the central device determines that all visitors have left the home area, the central device can control the central device and each controllable device to automatically exit visitor mode, and stop assisting the aforementioned silent devices in protecting privacy information and / or restricting sensitive operations.

[0408] In other examples, the preset exit condition may be other than what is specified. This application does not limit the specific content of the preset exit condition in its embodiments.

[0409] Optionally, the aforementioned visitors include a first type of visitor and a second type of visitor, with the first type of visitor having higher operating permissions than the second type of visitor.

[0410] It should be noted that the visitor types mentioned above can be set according to actual needs. For example, in some embodiments, the administrator (equipment manufacturer or holder of the central device) can define users other than family members as visitors; in other embodiments, the administrator can divide visitors into first-class visitors and second-class visitors. First-class visitors may refer to close relatives, acquaintances, and other visitors with relatively close relationships, while second-class visitors may refer to unfamiliar friends, on-site repair personnel, property management personnel, and other temporary visitors. First-class visitors have higher operation permissions than second-class visitors; in other embodiments, the administrator can also divide visitors into first-level visitors, second-level visitors, and third-level visitors, and set corresponding permissions for each level of visitors; in other embodiments, the administrator can also divide visitor types in other ways. This application does not limit the specific method by which the administrator divides visitor types.

[0411] Optionally, the above visitor modes include a first visitor mode and a second visitor mode;

[0412] When the aforementioned user identity includes the aforementioned visitor, entering visitor mode and instructing the controllable device to enter the aforementioned visitor mode includes:

[0413] When the aforementioned user identity includes the first type of visitor but does not include the second type of visitor, the system enters the first visitor mode and instructs the aforementioned controllable device to enter the first visitor mode.

[0414] When the aforementioned user identity includes the aforementioned second type of visitor, the aforementioned second visitor mode is entered, and the aforementioned controllable device is instructed to enter the aforementioned second visitor mode.

[0415] It should be noted that when the above visitors include both the first type of visitors and the second type of visitors, the above visitor patterns can include both the first visitor pattern and the second visitor pattern.

[0416] When a user's identity includes the first type of visitor but excludes the second type of visitor, the central device can control the central device and controllable devices to enter the first visitor mode with higher operating privileges.

[0417] When the user identity includes a second type of visitor, regardless of whether there is a first type of visitor in the home area, the central device can control the central device and the visitor device to enter the second visitor mode with lower operating permissions.

[0418] Using the above methods, the central device can manage different types of visitors more flexibly, provide different permissions to different types of visitors, prevent low-privilege visitors from stealing the operation permissions of high-privilege visitors, and protect the privacy, safety and property of family members.

[0419] Optionally, after entering the second guest mode and instructing the controllable device to enter the second guest mode, the method further includes:

[0420] When a family member's exit operation is detected, the system enters family member mode and instructs the aforementioned controllable devices to enter family member mode.

[0421] Alternatively, when a family member's exit operation is detected, the system enters the first visitor mode and instructs the controllable device to enter the first visitor mode.

[0422] It should be noted that when the central device is in second visitor mode and the central device detects a family member's exit operation, the central device can control the central device and controllable devices to directly enter home mode.

[0423] However, if the central device directly controls the central device and controllable devices to enter the family member mode, the visitor may steal the family member's permissions, and unauthorizedly view the family member's private information and / or perform sensitive operations.

[0424] Therefore, when the central device is in the second visitor mode and the central device detects the exit operation of a family member, the central device can also control the central device and controllable devices to enter the first visitor mode. This can satisfy the user's need to improve the visitor's permissions, and also prevent the visitor from using the family member's permissions without authorization in the family member mode, thereby protecting the privacy and personal and property safety of family members.

[0425] Optionally, after entering guest mode when the user includes the visitor, the following further applies:

[0426] The authorization code is displayed. This authorization code is used to request guest access from the target device, which is a family member's personal device.

[0427] It should be noted that in some scenarios, visitors may want to use their own personal devices to control electronic devices in the home area.

[0428] At this point, the central device can display an authorization code on the screen. The authorization code is used to request guest access from the target device, which is a family member's personal device.

[0429] Once a visitor scans the authorization code using their personal device, the visitor device can send an authorization request to the target device.

[0430] When the target device agrees to the above authorization request, the guest device can obtain guest permissions.

[0431] When the target device rejects the above authorization request, the guest device cannot obtain guest permissions.

[0432] Optionally, the aforementioned sensitive operations include home management operations and / or control operations on electronic devices with security functions.

[0433] It should be noted that sensitive operations refer to operations that may affect the personal safety and property security of family members.

[0434] Specifically, sensitive operations may include any one or more of the following: home management operations, control operations of security equipment, etc.

[0435] Among these, family management operations refer to operations such as changing family information, sharing permissions, and changing permissions. Security equipment refers to electronic devices with security functions.

[0436] Optionally, when the aforementioned user characteristics include the number of users and the aforementioned pre-stored characteristics include the number of household members, the process of obtaining the user characteristics of the aforementioned users, comparing the aforementioned user characteristics with the pre-stored characteristics, and determining the user identity of the aforementioned users includes:

[0437] Compare the number of users mentioned above with the number of family members mentioned above;

[0438] If the number of users exceeds the number of family members, then the user identity of the users is determined to include visitors.

[0439] It should be noted that the above user characteristics may include the number of users, and the above pre-stored characteristics may include the number of family members.

[0440] When the central device obtains the number of users, it can compare the number of users with the number of household members.

[0441] If the number of users is less than or equal to the number of household members, it means there may be no visitors in the household area.

[0442] If the number of users is greater than the number of people in the household, it means that there are visitors in the household area, and the central device can determine that the users mentioned above include visitors.

[0443] Optionally, the above-mentioned household population figures are determined based on the number of people staying overnight in the household area each day during a historical period.

[0444] It should be noted that the above-mentioned number of family members can be determined by the central equipment based on the number of people staying overnight in the family area each day during a historical period.

[0445] For example, assuming the historical time period is the most recent week, if the central device detects that the mode of the number of people staying overnight each day during the most recent week is 3, then the central device can determine the number of family members as 3.
