Description

Technical Field

[0001] This invention relates to the field of access control technology, specifically to an offline elevator or access control system and method. Background Technology

[0002] Currently, most offline card issuance methods for elevator or access control IC card systems involve equipping a card-issuing computer and software, and a card issuer. The card issuer writes the resident's elevator floor permissions into the IC card. This method increases the system hardware cost and requires card issuers to be familiar with the data configuration and operation of the card-issuing software, which invisibly increases the learning cost of the IC card system.

[0003] Some elevators use an IC card system that comes with an authorized card before the product leaves the factory. After the user swipes the authorized card, the IC card controller displays the current floor via voice or digital display. If the user then swipes a blank card, the current floor is written to the blank card or saved in the controller. If a different floor needs to be issued, the authorized card must be swiped multiple times to switch floors, which is quite cumbersome, especially for elevators with many floors.

[0004] In addition, for access control systems or elevators that use biometric identification, this method is highly susceptible to leakage of personal privacy information, posing a certain risk to the security of users' property and other assets. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, the purpose of this invention is to provide an offline elevator or access control system and method that can protect user privacy.

[0006] To address the aforementioned problems, a first aspect of this invention discloses an offline elevator or access control system, comprising a mobile terminal and an authentication terminal. The authentication terminal receives an access request and sends the access request to the mobile terminal, which then authenticates the access request and sends the authentication result to the authentication terminal. This enables the authentication terminal to control whether the elevator or access control system is activated based on the authentication result.

[0007] In a preferred embodiment of the present invention, in the first aspect of the present invention, the system further includes a cloud platform, the mobile terminal is used to obtain an authorization code and send a registration request to the cloud platform based on the authorization code, and after the registration request is approved, the cloud platform sends an authentication terminal device code to the mobile terminal and uses the mobile terminal to complete the information entry;

[0008] The authentication of the access request by the mobile terminal includes:

[0009] The verification information in the access request is compared with the authentication terminal device code sent by the cloud platform to the mobile terminal and the information entered by the mobile terminal. After the comparison is successful, the authentication terminal controls the elevator or access control system to start.

[0010] In a preferred embodiment, in the first aspect of the present invention, after the registration request is approved, information is entered using the mobile terminal, followed by:

[0011] The mobile terminal generates a verification code based on the entered information and sends the verification code to the cloud platform.

[0012] In a preferred embodiment, in the first aspect of the present invention, the access request is issued based on an IC card, and the information entered using a mobile terminal is the IC card identifier.

[0013] The authentication terminal receives the access request and extracts the unique identification code of the IC card, and sends the unique identification code and the authentication terminal device code to the mobile terminal;

[0014] The mobile terminal verifies whether the authentication terminal device code exists in its stored information. If it exists, it compares whether the IC card identifier it entered corresponds to the unique identification code sent by the authentication terminal. If they correspond, the comparison is successful.

[0015] If the mobile terminal does not store the authentication terminal device code in its storage information, or if the IC card identifier entered by the mobile terminal does not correspond to the unique identification code sent by the authentication terminal, the comparison will fail, and the authentication terminal will not start the elevator or access control system.

[0016] In a preferred embodiment, in the first aspect of the present invention, the passage request is issued based on liveness detection, and the information entered using the mobile terminal is liveness information.

[0017] The authentication terminal receives the access request, obtains liveness detection information, and sends the liveness detection information and the authentication terminal device code to the mobile terminal;

[0018] The mobile terminal verifies whether the authentication terminal device code exists in its stored information. If it exists, it compares whether the liveness information it entered corresponds to the liveness detection information. If they correspond, the comparison passes.

[0019] If the authentication terminal device code is not stored in the storage information of the mobile terminal, or if the liveness information entered by the mobile terminal does not correspond to the liveness detection information, the comparison will fail, and the authentication terminal will control the elevator or access control system to not start.

[0020] As a preferred implementation, in the first aspect of the present invention, comparing whether the entered liveness information corresponds to the liveness detection information includes:

[0021] Calculate the similarity between the liveness information and the liveness detection information. If the similarity is greater than or equal to a preset threshold, the comparison passes; otherwise, if the similarity is less than the preset threshold, the comparison fails.

[0022] A second aspect of this invention discloses an offline elevator or access control method, comprising:

[0023] The authentication terminal receives the access request and sends the access request to the mobile terminal;

[0024] The mobile terminal authenticates the access request and sends the authentication result to the authentication terminal, so that the authentication terminal can control whether the elevator or access control is started or not based on the authentication result.

[0025] In a preferred embodiment, in a second aspect of the present invention, the method further includes:

[0026] The mobile terminal sends a registration request to the cloud platform based on the authorization code;

[0027] The cloud platform reviews the registration request. Once the cloud platform approves the registration request, it sends an authentication terminal device code to the mobile terminal.

[0028] Use the mobile terminal to complete the information entry;

[0029] The mobile terminal authenticates the access request, including:

[0030] The mobile terminal compares the verification information in the access request with the authentication terminal device code sent by the cloud platform and the information entered by the mobile terminal. After the comparison is successful, the authentication terminal controls the elevator or access control system to start.

[0031] In a preferred embodiment, in a second aspect of the present invention, the method further includes:

[0032] The mobile terminal generates a verification code based on the entered information and sends the verification code to the cloud platform.

[0033] In a preferred embodiment, in the second aspect of the present invention, the access request is issued based on an IC card, and the information entered using a mobile terminal is the IC card identifier.

[0034] The authentication terminal receives the access request and extracts the unique identification code of the IC card, and sends the unique identification code and the authentication terminal device code to the mobile terminal;

[0035] The mobile terminal authenticates the access request, including:

[0036] The mobile terminal verifies whether the authentication terminal device code exists in its stored information. If it exists, it compares whether the IC card identifier it entered corresponds to the unique identification code sent by the authentication terminal. If they correspond, the comparison is successful.

[0037] If the mobile terminal does not store the authentication terminal device code in its storage information, or if the IC card identifier entered by the mobile terminal does not correspond to the unique identification code sent by the authentication terminal, the comparison will fail, and the authentication terminal will not start the elevator or access control system.

[0038] or,

[0039] The passage request is issued based on liveness detection, and the information entered using the mobile terminal is liveness information.

[0040] The authentication terminal receives the access request, obtains liveness detection information, and sends the liveness detection information and the authentication terminal device code to the mobile terminal;

[0041] The mobile terminal authenticates the access request, including:

[0042] The mobile terminal verifies whether the authentication terminal device code exists in its stored information. If it exists, it compares whether the liveness information it entered corresponds to the liveness detection information. If they correspond, the comparison passes.

[0043] If the authentication terminal device code is not stored in the storage information of the mobile terminal, or if the liveness information entered by the mobile terminal does not correspond to the liveness detection information, the comparison will fail, and the authentication terminal will control the elevator or access control system to not start.

[0044] In this embodiment of the invention, the user completes registration independently on the mobile terminal using an authorization code. After registration, the user-entered permission data is stored on the mobile terminal, and the authentication terminal does not store any user data. When the user requests access, the authentication terminal sends the received data to the mobile terminal, which then performs information comparison. If the comparison is successful, the authentication result is returned to the authentication terminal, which then performs the corresponding operation.

[0045] Compared with the prior art, the beneficial effects of the embodiments of the present invention are as follows:

[0051] This specific embodiment is merely an explanation of the embodiments of the present invention and is not intended to limit the embodiments of the present invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the embodiments of the present invention, they are protected by patent law.

[0052] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the embodiments of the present invention.

[0053] The term "comprising" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product or device.

[0054] In embodiments of the present invention, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design described as "exemplary" or "for example" in embodiments of the present invention should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0055] In this embodiment of the invention, users independently complete registration on a mobile terminal using an authorization code. After registration, the user-entered permission data is stored on the mobile terminal, while the authentication terminal does not store any user data. When a user requests access, the authentication terminal sends the received data to the mobile terminal, which then performs information comparison. If the comparison is successful, the authentication result is returned to the authentication terminal, which then performs the corresponding operations. The following is a detailed description in conjunction with the accompanying drawings.

[0056] Example 1

[0057] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of an offline elevator or access control system disclosed in one embodiment of the present invention. Figure 1 As shown, the offline elevator or access control system includes: an authentication terminal, a cloud platform, and a mobile terminal.

[0058] The authentication terminal is installed on the corresponding elevator or access control system. Access control is a broad concept, which includes not only physical doors in the narrow sense, but also access control devices such as turnstiles.

[0059] The authentication terminal can communicate with the mobile terminal wirelessly. In a preferred embodiment of the present invention, since card swiping or liveness detection is required for access management, the wireless communication method used here is mainly a short-range wireless communication method such as Bluetooth or NFC.

[0060] The authentication terminal is also connected to the elevator or access control controller via wired or wireless means. After a pass request is approved, the authentication terminal sends a control command to the elevator or access control controller to start the elevator or access control system. For example, the authentication terminal can communicate with the elevator or access control controller via a serial line or wirelessly via a wireless communication network such as the Internet.

[0061] "Starting" here refers to executing the corresponding operation. For example, for an elevator, if a user makes a passage request outside the elevator, the corresponding operation could include opening the door or calling the elevator. If a user makes a passage request inside the elevator, the corresponding operation could be starting the elevator and controlling it to run to the specified floor. The specific information of the specified floor is sent to the mobile terminal by the cloud platform when the user registers.

[0062] When a user sends a pass request to the authentication terminal, the authentication terminal receives the pass request and sends it to the mobile terminal for authentication. The entire authentication process does not require the involvement of the cloud platform. That is, neither the cloud platform nor the authentication terminal stores the user's personal privacy information, such as mobile phone number, name, and biometric information, thus ensuring user privacy.

[0063] The mobile terminal completes authentication based on the authentication terminal device code sent to the mobile terminal by the cloud platform during registration and the user information entered on the mobile terminal (which can be IC card identification or biometric information, i.e., liveness detection information). This effectively eliminates the risk of credentials such as IC cards being copied, because even if the credentials are copied, other user terminals besides the user's own mobile terminal cannot complete the registration, and therefore cannot complete the authentication process.

[0064] Taking elevator operation management as an example, the administrator creates a new community, room number, and authentication terminal on the cloud platform. The cloud platform generates a device code for each authentication terminal. Entering the device code on the authentication terminal completes the device registration. This device code is used for subsequent communication authentication with the mobile terminal. Each room number is preset with floor and available authentication terminal permission information.

[0065] For access control systems, it is generally sufficient to associate the authentication terminal with the user's permissions. That is, once the authentication terminal device code and user information are authenticated, there is no permission issue, and the authentication terminal can control the access control system to start, allowing the user to pass through.

[0066] When a mobile device registers with the cloud platform, it needs to obtain an authorization code first. Taking elevator operation management as an example, the administrator generates a specified number of mobile registration authorization codes for each room number in the community on the cloud platform, and then provides the authorization codes to users according to the room number.

[0067] For access control management, similar to elevator operation management, a specified number of mobile phone registration authorization codes can be sent to a designated person in charge. This person in charge can then redistribute the specified number of mobile phone registration authorization codes to specific users, who can then complete the registration process using these codes.

[0068] Users can register through the corresponding app, web page, and mini-program. During registration, the cloud platform does not store any private data such as the user's name or phone number; in other words, users do not need to enter such private information.

[0069] For example, a user can enter an authorization code on the login page to register. After receiving the registration request, the cloud platform marks the authorization code as used. If the authorization code is used to register again in the future, the registration will fail.

[0070] After successful registration, the cloud platform sends the authorization code, valid authentication terminal device code, and permission information to the user's mobile terminal. The user can then enter information on the mobile terminal's credential entry interface. This information can be an IC card identifier, such as the IC card number, which must correspond one-to-one with the IC card; that is, this IC card identifier can only correspond to one IC card. The IC card identifier can be entered manually or by NFC reading.

[0071] The information entered can also be liveness detection information, i.e., biometric information, such as fingerprints and facial information. Fingerprint information can be entered using the fingerprint recognition mechanism on the mobile terminal itself, while facial information can be entered by taking a photo or uploading a picture.

[0072] All of this data (IC card identification and / or liveness detection information) is stored on the user's mobile device and is not uploaded to the cloud platform.

[0073] To prevent users from repeatedly entering the same IC card identifier and / or liveness detection information on different mobile phones, the application generates a unique verification code (such as MD5 checksum) based on the content of each IC card identifier and / or liveness detection information credential data, and sends the verification code to the cloud platform. If the cloud platform detects that the verification code already exists, it returns a registration failure to the user; otherwise, the registration is successful.

[0074] Understandably, when the entered information is liveness detection information, the authentication terminal needs to have the corresponding detection institution. For example, when the liveness detection information is a fingerprint, the authentication terminal needs to have a fingerprint sensor, and when the liveness detection information is a face, the authentication terminal needs to have a face recognition device, such as a camera.

[0075] When using an IC card for authentication, i.e., when a user swipes their card at the authentication terminal to issue a pass request, the IC card identifier information needs to be entered during registration. The authentication terminal receives the pass request and extracts the unique identifier of the IC card from it, and sends the unique identifier and the authentication terminal device code to the mobile terminal. The mobile terminal verifies whether the authentication terminal device code exists in its stored information. If it exists, it compares whether the IC card identifier entered by the mobile terminal corresponds to the unique identifier sent by the authentication terminal. If they correspond, the comparison is successful. The IC card identifier and the IC card unique identifier can have the same meaning; here, the only distinction is between the two. Therefore, during the comparison, it is only necessary to determine whether the IC card identifier stored on the mobile terminal at the time of entry matches the unique identifier.

[0076] After the comparison is successful, the mobile terminal sends a confirmation message to the authentication terminal. In some cases, the authorization information sent by the cloud platform to the mobile terminal (e.g., in elevator operation management) will also be sent to the authentication terminal. After receiving the authorization information, the authentication terminal sends the authorization information to the elevator controller, and the elevator automatically or manually registers the floor button.

[0077] It is understood that if the mobile terminal does not store the authentication terminal device code in its storage information, or if the IC card identifier entered by the mobile terminal does not correspond to the unique identification code sent by the authentication terminal, the comparison will fail, and the authentication terminal will not start the elevator or access control system.

[0078] The above comparison process does not require the user to open the mobile phone application; the application can communicate with the authentication terminal in the background of the mobile phone.

[0079] Similarly, when a user verifies their identity using biometric information—that is, when the user issues a pass request via liveness detection at the authentication terminal—liveness information needs to be entered during registration. When a user undergoes liveness detection at the authentication terminal, the terminal receives the pass request, obtains the liveness detection information, and sends the liveness detection information and the authentication terminal device code to the mobile terminal. The mobile terminal verifies whether the authentication terminal device code exists in its stored information. If it does, it compares the entered liveness information with the liveness detection information. If they match, the comparison is successful.

[0080] Liveness detection information and liveness information can have the same meaning; they are used here only for distinction. Of course, in other embodiments, one or both of liveness detection information and liveness information can be biometric codes. For example, feature filtering can be performed through certain processing methods to retain the feature matrix corresponding to key features.

[0081] When the authentication terminal sends liveness detection information to the mobile terminal, it can first process the liveness detection information to generate a biometric code, or the mobile terminal can process the liveness detection information and liveness information to obtain a biometric code.

[0082] There are multiple ways to compare liveness information and liveness detection information. For example, the similarity between the two can be calculated by similarity calculation, such as by cosine similarity. When the similarity is greater than or equal to a preset threshold, the comparison is considered successful.

[0083] After the comparison is successful, the mobile terminal sends a confirmation message to the authentication terminal. In some cases, the authorization information sent by the cloud platform to the mobile terminal (e.g., in elevator operation management) will also be sent to the authentication terminal. After receiving the authorization information, the authentication terminal sends the authorization information to the elevator controller, and the elevator automatically or manually registers the floor button.

[0084] It is understood that if the authentication terminal device code is not stored in the storage information of the mobile terminal, or if the liveness information entered by the mobile terminal does not correspond to the liveness detection information, the comparison will fail, and the authentication terminal will control the elevator or access control system to not start.

[0085] Example 2

[0086] Please refer to Figure 2 As shown, an offline elevator or access control method may include the following steps:

[0087] S210. The mobile terminal sends a registration request to the cloud platform based on the authorization code; the cloud platform reviews the registration request, and when the cloud platform approves the registration request, the cloud platform sends an authentication terminal device code to the mobile terminal, and the mobile terminal completes the information entry.

[0088] S220. The authentication terminal receives the access request and sends the access request to the mobile terminal.

[0089] S230. The mobile terminal authenticates the access request and sends the authentication result to the authentication terminal, so that the authentication terminal controls whether the elevator or access control is started or not based on the authentication result.

[0090] The mobile terminal compares the verification information in the access request with the authentication terminal device code sent by the cloud platform and the information entered by the mobile terminal. After the comparison is successful, the authentication terminal controls the elevator or access control system to start.

[0091] The passage request is issued based on the IC card, and the information entered using the mobile terminal is the IC card identifier;

[0092] The authentication terminal receives the access request and extracts the unique identification code of the IC card, and sends the unique identification code and the authentication terminal device code to the mobile terminal;

[0093] The mobile terminal authenticates the access request, including:

[0094] The mobile terminal verifies whether the authentication terminal device code exists in its stored information. If it exists, it compares whether the IC card identifier it entered corresponds to the unique identification code sent by the authentication terminal. If they correspond, the comparison is successful.

[0095] If the mobile terminal does not store the authentication terminal device code in its storage information, or if the IC card identifier entered by the mobile terminal does not correspond to the unique identification code sent by the authentication terminal, the comparison will fail, and the authentication terminal will not start the elevator or access control system.

[0096] or,

[0097] The passage request is issued based on liveness detection, and the information entered using the mobile terminal is liveness information.

[0099] The mobile terminal authenticates the access request, including:

[0100] The mobile terminal verifies whether the authentication terminal device code exists in its stored information. If it exists, it compares whether the liveness information it entered corresponds to the liveness detection information. If they correspond, the comparison passes.

[0101] If the authentication terminal device code is not stored in the mobile terminal's storage information, or if the liveness information entered using the mobile terminal does not correspond to the liveness detection information, the comparison fails, and the authentication terminal will not control the elevator or access control system to start.
