In order to make the person skilled in the art better understand the solution of the present application, the technical solution of the embodiment of the present application will be clearly and completely described below with reference to the accompanying drawings.

In some specific situations, the multi-face collaborative encryption unlocking is a very practical technical scheme. For example, in the protection of important public equipment of enterprises, common property of couples, important secrets of collective, large payment management and the like, certain decisions can be made on the basis of the consensus among multiple people, and the collaborative encryption unlocking scheme of the multiple faces can effectively and conveniently maintain the consensus protocol so as to ensure the collective benefit. However, the prior art cannot meet the real-time remote multi-user collaborative unlocking, and the present inventors propose the following specific ways to solve the above problems.

In a first aspect, an embodiment of the present invention provides an unlocking method, fig. 1 is a flowchart of a specific embodiment of the unlocking method of the present invention, and according to the method shown in fig. 1, the method of the present embodiment includes:

Step 110, the server obtains an unlocking request sent by at least one terminal, where the unlocking request carries identification information of a lock. In this step, the server obtains the unlocking request sent by the terminal, and it can be understood that the multi-user collaborative unlocking includes at least two authority users, and it can be set that only when all authority users perform collaboration, the unlocking can be completed, or it can also be set that all authority users are not required, for example, a certain proportion of people are preset to complete collaborative unlocking, or the authority users are set with levels, and different unlocking weights are given to authority users with different levels. The embodiment is not limited to this, and for convenience of description, the embodiment of the application takes the case that all right users cooperate to complete unlocking. The authority user is a user with unlocking authority, and in the embodiment of the application, the server confirms the authority user through facial image feature comparison. The specific method for extracting the facial image features and comparing the facial image features can be performed by adopting the existing and future technologies, and the embodiment of the application is not limited to the existing and future technologies.

In an embodiment of the present application, it is understood that a server may manage a plurality of locks, and for each individual lock, the locks may be distinguished by, for example, a serial number, or identification information. Taking one lock as an example, the server can store the face image feature of the authority user corresponding to the lock and the association relation between the lock and the authority user, namely the face feature, for the lock in advance, and the pre-storage process can be realized by an encryption process, and can be particularly seen in a specific embodiment corresponding to fig. 2. It will be appreciated that in describing embodiments of the present application, the rights user stored in the server, that is, the face features or face image features comprising the rights user, are sometimes not distinguished from each other.

However, in any mode, the unlocking request sent by the terminal can carry the identification information of the lock, so that the server can implement the subsequent unlocking step according to the association relationship between the pre-stored lock and the authorized user.

And 120, the server acquires at least two face images sent by the terminal. It can be understood that at least two users participating in collaborative unlocking, that is, at least two authorized users associated with one lock, are provided, but the server side is not limited to whether the at least two users are performed through the same terminal or different terminals when the collaborative unlocking is performed. For example, each user may perform cooperative unlocking through a respective terminal, or at least two users may perform cooperative unlocking through the same terminal, which is not limited by the present application.

Therefore, the server may receive at least two face images sent by at least one terminal, and the server may acquire one face image from each of the two terminals in the cooperative unlocking process, or acquire face images from two or more terminals respectively in the cooperative unlocking process, acquire one face image sent by the terminal from some of the terminals, and acquire a plurality of face images sent by the terminal from another of the terminals. The server acquires several face images from several terminals, respectively, which are determined by the operations of the terminal users participating in the cooperative unlocking, and the server is not limited thereto. However, in the collaborative unlocking process, the server receives at least two face images sent by the terminal, so that the server can conveniently identify which lock of the locks managed by the server is subjected to collaborative unlocking operation, and the face images sent by the terminal and received by the server can all carry the identification number of the lock to be unlocked.

Step 130, the server performs living body detection on the at least two face images; in this step, the server performs living body detection on at least two received face images. The living body detection can specifically employ various prior art techniques including various anti-attack techniques and the like. The server can perform living detection when a face image is obtained, or can perform living detection after the face image with the same number of authorized users is obtained.

After the biopsy has passed, subsequent steps may be performed. And when the acquired face image fails to pass through the living body detection, the server can make a decision to terminate unlocking. Meanwhile, the server can send the information of stopping unlocking to the users participating in collaborative unlocking. Specifically, the server may select a reserved contact address, such as a cell phone number, a mailbox number, or the server may send the information to a terminal participating in collaborative unlocking, where the information is sent to the user by a variety of methods, for example, the server may send the information to a reserved contact address of the authorized user of the lock. Further, the server may instruct the terminal to create a session through which information to be transmitted is displayed. This way, the user can be informed about the possible abnormality or risk by obtaining information or progress about the unlocking at any time.

It can be understood that the server may send the information to the terminal participating in the collaborative unlocking through various existing technologies, and the description of the present application is omitted. The transmission method of the subsequent server for transmitting various other information may refer to various methods or combinations of the methods using the present step, and for simplicity of description, repeated description will not be made.

And 140, extracting the characteristics of the face image detected by the living body, and comparing the extracted characteristics with a plurality of face characteristics stored in advance, wherein the plurality of face characteristics are the face characteristics of a plurality of authority users associated with the identification information of the lock.

In this step, the server extracts the facial image features of the face detected by the living body, and any existing or future technique may be adopted for the feature extraction method. And comparing the extracted face features with the face features stored in advance. At least two rights users are in the multi-person collaborative unlocking, so that at least two stored face features are realized. The server inquires authority users associated with the locks of the identification numbers stored in advance at the server side according to the identification numbers to be unlocked carried by the acquired face images, namely inquires face characteristics of the authority users corresponding to the identification numbers. And comparing the obtained face characteristics with the face characteristics stored in the implementation mode.

Specifically, each time a face image sent by a terminal is obtained, the image is compared with the face features of N (N is at least 2) authority users stored in advance, and if the comparison result is that the face image is a certain authority user, the comparison is considered to be successful.

At this time, the server may further send the information that the authority user is successfully compared or verified to the authority user or to the terminal participating in collaborative unlocking. This way, the user may be enabled to obtain information or progress regarding the unlocking, knowing what anomalies or risks may be present, in various ways. For example, other non-authorized users can perform unlocking operation, and the authorized users can know the unlocking operation through reserved information, so that the safety can be further improved.

Further, the server can use the information as the reminding information and display the reminding information through the session in a mode of instructing the terminal to create the session. The mode of the session can transmit and update the unlocking state in real time, and user experience is improved.

Specifically, the server may also set a progress bar according to the number of authorized users and the number of authenticated users, so as to intuitively display the unlocking progress in the session. For example, when there are four authorized users, one of the facial image features is successfully compared, i.e. the verification is passed, the current quarter progress bar is displayed.

Further, if the face image feature is compared with N preset stored authority users, the server considers that the face is not any authority user according to preset conditions, verification is considered to be failed, and at this time, the server can terminate unlocking. And correspondingly, the information can also be sent to the authorized user or the terminal participating in unlocking.

The preset condition of success or failure of the server to the facial feature comparison can be realized by a technology updated continuously in the field, and the application is not limited.

When the server confirms that the received first face image is one of N authority users through face feature comparison, when the server acquires one face image sent by the terminal again, the face image can be compared with the face features of the rest (N-1) authority users, if the comparison is successful, the unlocking progress is updated to be one half, and if the verification fails, the unlocking is stopped, and a message is sent. Of course, the server may also compare the face image received each time with all N authorized users. The invention is not limited either.

And 150, when the comparison result shows that the plurality of right users have identical faces in face images obtained from the terminal by the server, the server sends an unlocking instruction.

And (3) repeating the face feature comparison of the step 140, and considering that the unlocking is successful when the face image features acquired from the terminal are successfully compared and all authorized users are verified. The server can send an unlocking instruction to the terminal so that the terminal can communicate with the lock to be unlocked after receiving the unlocking instruction, and unlocking operation is achieved.

According to the unlocking method, the face image features sent by the terminal are extracted and compared with the face features of the plurality of stored authority users, and when all authority users have identical faces in the face images obtained by the server from the terminal, unlocking is carried out, so that the real-time remote unlocking of the cooperation of multiple persons is realized, on one hand, the unlocking safety is ensured, and on the other hand, the requirements of online and real-time remote unlocking of various scenes are met.

In another specific embodiment, after the unlocking request is obtained, the server obtains the information of the associated authority user according to the identification information of the lock; the server sends reminding information to the associated user according to the information of the associated authority user, wherein the reminding information comprises one or more of the following: unlocking progress, anomaly information, which may include one or more of: and the living body detection failure information and the face feature comparison failure information.

Further, in another embodiment, after the unlocking request is obtained, if the server does not send the unlocking instruction within a preset time, the unlocking is terminated, and the risk can be reduced by limiting the unlocking time, so that the security index is further improved.

In a second aspect, an embodiment of the present invention provides an encryption method, and fig. 2 is a flowchart of a specific embodiment of the encryption method of the present invention, where, according to the method shown in fig. 2, the method of the present embodiment includes:

Step 210, the server acquires a registration request, wherein the registration request carries identification information of a lock to be encrypted; in general, when a user obtains a lock device, an application can be downloaded and installed through a corresponding two-dimensional code, and when the user opens the application, an initialization flow of device configuration can be entered. After purchasing the lock, the settings that the user wants to make before decrypting are encryption settings. The lock device may be configured with a module or a port for accessing to a network, for example, WIFI may be accessed to a WIFI network or other networks in the present or future, and specifically, the lock device may also be configured with a terminal, for example, a mobile phone terminal, or the like. The network configuration method and the hardware used can adopt various prior art, and the application is not limited by the application.

After the network configuration of the lock device is successful, the terminal can send the acquired identification information of the lock device to the server to request registration. Correspondingly, the server acquires a registration request sent by the terminal, wherein the registration request carries identification information of the lock to be encrypted. The server may also establish a library of lock devices managed by the server through the identification information, or the server itself may store the lock devices managed by the server, and may determine whether the lock belongs to the lock device managed by the server itself according to the identification information.

Step 220, the server acquires at least two face images sent by at least one terminal, wherein the at least two face images are associated with the identification of the lock to be encrypted; it can be understood that under the condition of cooperative unlocking, at least two authority users can perform cooperative unlocking, namely, at least two authority users associated with one lock are provided, so that in this step, the server acquires at least two face images sent by at least one terminal, and in order to enable the server to know which authority user of the lock the received face image is, the at least two face images can also carry the identification of the lock to be encrypted, so that the at least two face images are associated with the identification of the lock to be encrypted.

Step 230, the server performs living body detection on the at least two face images; in this step, the server performs living body detection on at least two received face images. The living body detection can specifically employ various prior art techniques including various anti-attack techniques and the like.

After the biopsy has passed, subsequent steps may be performed. When the acquired face image fails to pass through the living body detection, the server can send reminding information to the user or the terminal, and the specific reminding mode can refer to the embodiment corresponding to fig. 1. When the user fails to pass the live detection, the server can terminate the encryption process, and can further remind the user to restart the encryption process.

Step 240, extracting features of the at least two face images after passing through the living body detection; in this step, the server extracts the facial image features of the face detected by the living body, and any existing or future technique may be adopted for the feature extraction method.

Step 250, establishing an association relationship between the identification of the lock to be encrypted and the features of the at least two face images, so that the user corresponding to the features of the at least two face images is a right user, and the right user can unlock the lock through the server;

As can be seen from step 220, the at least two face images acquired by the server may further carry the identification of the lock to be encrypted, so that the at least two face images are associated with the identification of the lock to be encrypted.
