[0079] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present application.

[0080] As the process of home intelligence continues to advance, the issue of privacy and security protection has become particularly prominent and urgently needs to be addressed. The core support for the interconnection and interoperability between home intelligent devices and home systems lies in the cloud service system. However, there are many potential risks in the complex process of data transmission between the device side and the cloud and data processing in the cloud. Data is at risk of being maliciously stolen and illegally leaked. Key information such as video recordings of daily family activities and personalized preference setting data of family members, once obtained by lawbreakers, is very likely to cause serious and immeasurable damage to the personal and property safety of the family and the privacy rights of individuals. Therefore, the embodiments of this application provide a security protection method, device, equipment, and storage medium.

[0081] The embodiments of this application provide a security protection method that can be applied to a control device, such as: a home host, as Figure 1 shown, including:

[0082] Step S101, obtain a distribution and positioning map including multiple surrounding electronic devices;

[0083] In the embodiments of this application, multiple millimeter-wave radars with different orientations are set in the control device. The surrounding area can refer to the detection range of the millimeter-wave radar. An electronic device can refer to an intelligent device that can collect sound, pictures, or videos and has an Internet connection function, such as: a surveillance camera, an intelligent voice interaction device, a TV, an air conditioner, a floor cleaning robot, etc. Multiple electronic devices can respectively establish a communication connection with the control device and receive control instructions from the control device.

[0084] The distribution and positioning map takes the control device as the origin and constructs a three-dimensional coordinate system, in which the three-dimensional coordinates corresponding to each electronic device are marked.

[0085] Since the placement position of the electronic device may change according to the user's usage habits, the distribution and positioning map can generate a new distribution and positioning map at preset time intervals (such as: 10 minutes, 1 hour, 12 hours, etc.) and record the generation time to update the position of the electronic device in real time. In this step, the distribution and positioning map with the most recent generation time can be obtained to ensure that the obtained position of the electronic device is more in line with the actual situation.

[0086] Step S102, determine whether there is an abnormal fluctuation in the surrounding electromagnetic wave signal;

[0087] Since an electronic device emits an electromagnetic wave signal when it is enabled and causes network fluctuations when transmitting data through the network, both of which will cause fluctuations in the electromagnetic wave signal. This kind of fluctuation is different from the fluctuation when the electronic device is not enabled or not transmitting data through the network. Therefore, it can be considered that an abnormal fluctuation in the electromagnetic wave signal will occur when the electronic device is enabled or transmitting data through the network.

[0088] Step S103: If the surrounding electromagnetic wave signals show abnormal fluctuations, determine the target electronic device in the area where the abnormal fluctuations of the electromagnetic wave signals occur according to the distribution positioning map.

[0089] In this step, when the surrounding electromagnetic wave signals show abnormal fluctuations, the area where the abnormal fluctuations of the electromagnetic wave signals occur can be determined, and the electronic devices within the area of the abnormal fluctuations of the electromagnetic wave signals in the distribution positioning map are determined as the target electronic devices. That is to say, it is considered that the abnormal fluctuations of the electromagnetic wave signals are caused by the activation of the target electronic device or the transmission of data through the network.

[0090] Step S104: Initiate the security protection operation for the target electronic device.

[0091] In the embodiment of the present application, the security protection operation includes: cutting off the network connection of the target electronic device, shielding the data collection function (such as audio, video, pictures, etc.) of the target electronic device through high-intensity electromagnetic waves, and controlling the target electronic device to stop collecting data and transmitting the collected data through the network, etc.

[0092] In an implementation manner of the present application, initiating the security protection operation for the target electronic device includes: sending a network disconnection instruction to the target electronic device to enable the target electronic device to cut off the network connection; and / or, sending high-intensity electromagnetic waves to the target electronic device.

[0093] The control device can pre-define the format of the network disconnection instruction with the electronic device to ensure that the electronic device can correctly parse the network disconnection instruction.

[0094] In the embodiment of the present application, when it is determined that the electromagnetic wave signals around the control device show abnormal fluctuations, the target electronic device that causes the abnormal fluctuations of the electromagnetic wave signals can be automatically determined according to the distribution positioning map, and then the security protection operation for the target electronic device is initiated, avoiding possible user privacy leakage behaviors of the target electronic device, such as collecting privacy data and transmitting privacy data, etc., ensuring the security of user privacy data, and preventing the leakage of user privacy data.

[0095] In practical applications, when the control device turns on the security protection mode, step S101 can be triggered to obtain the distribution positioning map including multiple surrounding electronic devices. Therefore, after the control device turns on the security protection mode, it is possible to prevent the target electronic device from collecting privacy data and transmitting privacy data through the network, prevent the theft and leakage of user privacy data, and effectively protect personal privacy security.

[0096] This application can achieve unified privacy and security management within a region based on a control device (such as a home host), and perform privacy and security shielding on other electronic devices in the surrounding area, including the capture of audio and video streams, the transmission of network data, etc., enabling various small and large smart devices of different brands in the home to enter the security mode for shielding and capture at any time within the coverage of the home host.

[0097] In another embodiment of this application, step S102 determines whether there is an abnormal fluctuation in the surrounding electromagnetic wave signals, including:

[0098] Step S201, send a first detection electromagnetic wave to the surrounding area;

[0099] In an embodiment of this application, the first detection electromagnetic wave can refer to an electromagnetic wave signal with a preset frequency, such as: 2.400 GHz, 5.15 GHz, etc.

[0100] In this step, the first detection electromagnetic wave can be broadcast to the surrounding area through a millimeter-wave radar.

[0101] Step S202, if the first reflected electromagnetic wave is received, obtain the first parameter data of the first reflected electromagnetic wave;

[0102] Due to factors such as the Doppler effect and distance change, the frequency of the reflected signal of the millimeter-wave radar and the frequency of the transmitted signal are usually not the same. Therefore, the first parameter data of the first reflected electromagnetic wave can be obtained. Exemplarily, the first parameter data can refer to the frequency.

[0103] Step S203, determine whether the first parameter data is outside the preset parameter range;

[0104] In an embodiment of this application, a preset parameter range can be set in advance. The preset parameter range can be determined according to the data range of the first parameter of the reflected electromagnetic wave received after the detection electromagnetic wave is sent by the millimeter-wave radar when there are no electronic devices enabled or data is transmitted through the network around the control device.

[0105] In this step, the first parameter data can be compared with the upper and lower limits of the preset parameter range. If the first parameter data is less than the lower limit or greater than the upper limit of the preset parameter range, it can be determined that the first parameter data is outside the preset parameter range.

[0106] Step S204, if the first parameter data is outside the preset parameter range, determine that there is an abnormal fluctuation in the surrounding electromagnetic wave signals.

[0107] In an embodiment of the present application, by comparing the first parameter data of the first reflected electromagnetic wave with a preset parameter range, when the first parameter data is outside the preset parameter range, it can be determined that the electromagnetic wave signal around has an abnormal fluctuation, quantifying the detection of whether the electromagnetic wave signal has an abnormal fluctuation, and obtaining the abnormal fluctuation detection result, so as to accurately detect the behavior of surrounding electronic devices leaking user privacy.

[0108] In another embodiment of the present application, step S101 of obtaining a distribution positioning map including multiple surrounding electronic devices includes:

[0109] Step S301, controlling the millimeter-wave radar sensor to send a second detection electromagnetic wave to the surroundings;

[0110] In an embodiment of the present application, the second detection electromagnetic wave may refer to millimeter waves.

[0111] In this step, millimeter waves can be broadcast to the surroundings through the millimeter-wave radar.

[0112] Step S302, if the second reflected electromagnetic wave is received, generating a three-dimensional mapping diagram of the surrounding objects according to the second reflected electromagnetic wave;

[0113] The distance data points between the millimeter-wave radar and the surrounding objects can be obtained according to the second reflected electromagnetic wave. Each distance data point represents the distance information between the millimeter-wave radar and a point on the surface of a certain object. The distance information and the angular data between the millimeter-wave radar and the object are represented in polar coordinates, and then the polar coordinates are converted into Cartesian coordinates to obtain point cloud data, and the three-dimensional mapping diagram is drawn according to the point cloud data.

[0114] Step S303, sending a communication request to each surrounding electronic device;

[0115] Exemplarily, the communication request may refer to a network authentication request, such as obtaining the mac address, device model, manufacturer information, etc.

[0116] Step S304, if a communication response is received, obtaining the fluctuation direction of the abnormal fluctuation of the electromagnetic wave signal around at the moment when the communication response is received;

[0117] After receiving the communication response, it can be encrypted by hash conversion according to the communication response, and then converted into base64 to form a unique device signature.

[0118] In an embodiment of the present application, the direction pointed by the millimeter-wave radar that receives the electromagnetic wave signal with an abnormal fluctuation (that is, the parameter data exceeds the preset parameter range) at the moment when the communication response is received can be determined as the fluctuation direction of the abnormal fluctuation.

[0119] Step S305, generating the distribution positioning map according to the fluctuation direction and the three-dimensional mapping diagram.

[0120] In this step, the fluctuation direction can be matched with the coordinates of the electronic device in the 3D mapping diagram, and a distribution positioning diagram is generated centered on the coordinates of the successfully matched electronic device. The distribution positioning diagram can include the area range where the electronic device is located and can also include the fluctuation direction.

[0121] After each regeneration of the distribution positioning diagram, the newly generated distribution positioning diagram can be compared with the previously generated one, a communication request is sent again to the electronic device whose position has changed, and the moment when the communication response is received and the direction pointed by the millimeter-wave radar that receives the electromagnetic wave signal with abnormal fluctuations are recorded as the latest fluctuation direction corresponding to the electronic device whose position has changed for subsequent use.

[0122] The embodiment of the present application can automatically generate a distribution positioning diagram according to the fluctuation direction of the electromagnetic wave signal with abnormal fluctuations and the 3D mapping diagram. The distribution positioning diagram is finally generated through two dimensions, namely the fluctuation direction and the 3D mapping diagram, so that the position of the electronic device in the generated distribution positioning diagram is more accurate.

[0123] In another embodiment of the present application, step S103 of determining the target electronic device in the area where the electromagnetic wave signal has abnormal fluctuations according to the distribution positioning diagram includes:

[0124] Step S401, obtaining one or more source directions of the first reflected electromagnetic wave corresponding to the first parameter data located outside the preset parameter range;

[0125] In the embodiment of the present application, the direction pointed by the millimeter-wave radar that receives the first reflected electromagnetic wave corresponding to the first parameter data located outside the preset parameter range can be determined as the source direction.

[0126] Step S402, determining the area where the electromagnetic wave signal has abnormal fluctuations according to one or more of the source directions;

[0127] The area formed by multiple source directions is determined as the area where the electromagnetic wave signal has abnormal fluctuations.

[0128] Step S403, if there is one electronic device in the area in the distribution positioning diagram, the electronic device in the area in the distribution positioning diagram is determined as the target electronic device.

[0129] In the embodiment of the present application, when there is one electronic device in the area with abnormal fluctuations, the only electronic device can be directly determined as the target electronic device, improving the determination efficiency of the target electronic device.

[0130] In yet another embodiment of the present application, step S103 for determining a target electronic device in the area where abnormal fluctuations of the electromagnetic wave signal occur according to the distribution positioning map further includes:

[0131] Step S501, if there are multiple electronic devices in the area in the distribution positioning map, obtain the operating state parameters of the multiple electronic devices;

[0132] In the embodiments of the present application, the operating state parameters may include: network state parameters (such as uplink and downlink transmission rates) and device enabled states, etc.

[0133] Step S502, if the operating state parameters of any one of the electronic devices meet the preset conditions, determine the electronic device as the target electronic device.

[0134] In the embodiments of the present application, when there are multiple electronic devices in the abnormal fluctuation area, the electronic device that is enabled or is transmitting data through the network can be directly determined through the operating state parameters of the electronic device, and it is determined as the target electronic device, determining the target electronic device from the root cause (transmitting data through the network), and improving the determination efficiency of the target electronic device.

[0135] In yet another embodiment of the present application, step S103 for determining a target electronic device in the area where abnormal fluctuations of the electromagnetic wave signal occur according to the distribution positioning map further includes:

[0136] Step S601, if there are multiple electronic devices in the area in the distribution positioning map, determine the electronic device closest to the center of the area according to the positions of the electronic devices in the distribution positioning map;

[0137] Step S602, determine the electronic device closest to the center of the area as the target electronic device.

[0138] In the embodiments of the present application, when there are multiple electronic devices in the abnormal fluctuation area, the electronic device closest to the center of the area can be determined as the target electronic device. Because there is a trend that the intensity of the electromagnetic wave signal gradually decreases towards the center, the electronic device with the maximum intensity, that is, the electronic device closest to the center of the area, can be determined as the target electronic device, improving the determination efficiency of the target electronic device.

[0139] In yet another embodiment of the present application, step S103 for determining a target electronic device in the area where abnormal fluctuations of the electromagnetic wave signal occur according to the distribution positioning map further includes:

[0140] Step S701, if there are multiple electronic devices in the area in the distribution positioning map, obtain the fluctuation direction of the abnormal fluctuation of the electromagnetic wave signal corresponding to each electronic device;

[0141] Step S702: Determine the electronic device that matches the fluctuation direction in the distribution positioning map as the target electronic device.

[0142] Since the fluctuation direction corresponding to each electronic device has been recorded in the foregoing embodiments, in the embodiments of the present application, when there are multiple electronic devices in the abnormal fluctuation area, the electronic device that matches the fluctuation direction can be directly determined as the abnormal electronic device, improving the determination efficiency of the target electronic device.

[0143] For ease of understanding, the present application also provides an embodiment in practical applications, as Figure 2 shown.

[0144] First step: Initial configuration of the security mode of the home host;

[0145] When the home host is started for the first time, a user operation entry is provided for the user to perform authorization for the home host permissions, including authorization for advanced permissions such as the permission configuration of the home network, to ensure that sufficient permissions are obtained to enable the security mode service with the knowledge and consent of the user.

[0146] Second step: Scanning of the home and smart home devices;

[0147] The home host will officially carry out the control work in the home area. First, a home scan will be performed. By collocating with a high-precision electromagnetic wave module (such as a millimeter-wave radar), the whole house will be detected using electromagnetic waves. Since the propagation speed and attenuation degree of electromagnetic waves are different in different media, for example: the propagation speed of electromagnetic waves in the air is relatively fast, but they will be attenuated to varying degrees in materials such as walls and metals. By measuring the attenuation degree of electromagnetic waves, the positions of obstacles such as walls and metals (smart home devices) can be roughly identified. Because this 3D mapping does not require high precision, the attenuation and response rate of electromagnetic waves can be used to identify obstacles such as walls, and different wavelengths can penetrate different walls, combined with obtaining a 3D mapping of the home.

[0148] The network authentication requests are unilaterally sent directly or indirectly (through other protocol conversion devices) to all smart devices in the home through the network routing permissions obtained by authorization, (obtaining information such as the MAC address, device model, and manufacturer information) and performing hash conversion encryption, and then converting to base64 to form a unique device signature. Combining with the generated 3D mapping of the home, the shape and material of the device object are judged by millimeter-wave radar detection, and the distribution positioning and marking of all network devices in the home are realized through algorithm positioning by matching the currently connected devices.

[0149] Third step: Execution process of the security mode;

[0150] After the home host enables the security mode, the electromagnetic wave module in the home host will continue to be covered and enabled. If there are electronic devices such as cameras and recorders enabled in the home, the enabled electronic devices will release abnormal electromagnetic waves (when enabling the security mode, what the user needs is an absolutely safe state without any enabled electronic devices. Since it is impossible to ensure which electronic devices have potential recording and video functions, any device working behavior in the area is considered abnormal electromagnetic waves), which will form conflicting electromagnetic waves with the high-precision electromagnetic wave module in the home host (all electronic devices will release electromagnetic wave signals during operation. After using the detected electromagnetic waves of the home host as the source to release the electromagnetic wave coverage area, if there are other electromagnetic wave signals in the area, it means that there are electronic devices working. The convergence of the two electromagnetic waves is a conflict, just like the conflict when two ripples converge after throwing two stones into a quiet pool of water). If conflicting electromagnetic waves occur, an alarm will be issued for reminder. At the same time, the home host will combine the 3D mapping diagram with the distribution and positioning of the devices, distinguish some non-threatening devices according to the home device positioning map obtained from the above 3D mapping, and output high-precision strong electromagnetic waves to the threatening devices in a targeted manner, that is, disconnect the network connection at the physical layer. Under the coverage of high-precision strong electromagnetic waves, the audio and video device functions in the target electronic device can be accurately shielded (that is, the output of electromagnetic waves will physically interrupt the networking signal of the device, and due to the influence of electromagnetic waves, the recording and video functions will also cause signal interference and cannot record clearly, providing double protection), and it will not affect the normal use of the rest of the devices, achieving intelligent targeted shielding of abnormal devices and accurately interrupting the device's access to the network by identifying the device's location to ensure that the device cannot communicate with the external network.

[0151] Step 4: Diary recording of the security mode;

[0152] After exiting the security mode, the home host will stop the electromagnetic wave output, and all intelligent devices will resume normal functions, and record all operation logs during the security mode for the user to view and analyze afterwards.

[0153] Finally, through the above implementation plan, various intelligent devices in the home can enter the security mode at any time for shielding and capture within the coverage area of the home host, ensuring that the privacy of the home is not leaked.

[0154] Based on the home host, this application provides a security protection method through the security mode, which can flexibly start and stop the security mode through various triggering methods such as manual, automatic, and abnormal detection self-start. When the home host is starting up, it will automatically act as a scanning guard to authenticate the access of all devices in the coverage area to the home network, and scan and mark abnormal devices and sensitive devices.
