In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

Under some specific situations, the multi-face collaborative encryption unlocking is a very practical technical scheme. For example, when important public equipment of an enterprise, common property of a couple, important confidentiality of a group, large-amount payment management and the like are protected, certain decisions can be made on the basis of consensus of multiple persons, and at the moment, the multiple-face collaborative encryption unlocking scheme can effectively and conveniently maintain the consensus protocol, so that the collective benefits are guaranteed. However, the prior art cannot meet the requirement of real-time remote multi-person cooperative unlocking, and the invention of the application provides the following specific modes for solving the problems in the prior art.

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

step 110, the server obtains an unlocking request sent by at least one terminal, wherein the unlocking request carries identification information of the lock. In this step, the server obtains the unlocking request sent by the terminal, and it can be understood that the multi-user cooperative unlocking includes at least two authority users, and it may be set that the unlocking can be completed only when all the authority users perform cooperation, or it may be set that all the authority users are not necessarily completed, for example, a certain proportion of people are preset to complete the cooperative unlocking, or the authority users are set with levels, and different unlocking weights are given to the authority users with different levels. This embodiment is not limited to this, and for convenience of description, in the embodiment of the present application, for example, the unlocking can be completed only by performing cooperation between all authorized users. The authorized user is a user with unlocking authorization, and in the embodiment of the application, the server confirms the authorized user through face image feature comparison. The specific methods 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 methods.

In the embodiment of the present application, it is understood that one server may manage several locks, and for each individual lock, the individual locks may be distinguished by, for example, a serial number, identification information, or the like. Taking one of the locks as an example, the server may store, in advance, the facial image feature of the authorized user corresponding to the lock and the association relationship between the lock and the authorized user, that is, the facial feature, for the lock, and the pre-storage process may be implemented by an encryption process, which may specifically refer to the specific embodiment corresponding to fig. 2. It is understood that in the description of the embodiment of the present application, the authorized user stored in the server, that is, the facial features or facial image features of the authorized user, sometimes several expressions are not distinguished.

However, in any way, 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 pre-stored association relationship between the lock and the authorized user.

And step 120, the server acquires at least two face images sent by the terminal. It can be understood that at least two users participating in the cooperative unlocking have at least two bits, that is, at least two rights users associated with one lock have at least two bits, but for the server side, it is not limited that the at least two users perform the cooperative unlocking through the same terminal or through different terminals. For example, each user may perform the cooperative unlocking through a respective terminal, or at least two users may perform the cooperative unlocking through the same terminal, which is not limited in this application.

Therefore, the server may receive at least two face images sent by at least one terminal, and the server may also obtain one face image from each of the two terminals in the cooperative unlocking process, or obtain one face image from each of two or more terminals in the cooperative unlocking process, obtain one face image sent by one terminal from some terminals, and obtain a plurality of face images sent by the terminals from some terminals. The server acquires several face images from several terminals respectively, which are determined by the operation of the terminal users participating in the cooperative unlocking, and the server does not limit the operation. However, in the cooperative unlocking process, the server receives at least two face images sent by the terminal, and in order to facilitate the server to identify which lock of the locks managed by the server is subjected to the cooperative unlocking operation by the acquired face images, the face images sent by the terminal received by the server can 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 the step, the server performs living body detection on the received at least two face images. The living body detection can specifically adopt various existing technologies, including various anti-attack technologies and the like. The server can perform living body detection when receiving a face image, and can also perform living body detection after receiving the face image with the number equal to that of authorized users.

After the live body detection passes, the subsequent steps may be performed. And when the acquired face image fails to successfully pass the living body detection, the server may make a decision to terminate the unlocking. Meanwhile, the server can send the information of terminating the unlocking to the users participating in the collaborative unlocking. Specifically, the server may select to send the information to the user through a plurality of methods, for example, the server may send the information to a reserved contact information of an authorized user of the lock, such as a mobile phone number and a mailbox number, or the server may send the information to a terminal participating in the cooperative unlocking. 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 or scheduled about the unlocking at any time, and can know possible abnormalities or risks.

It can be understood that the server may send the information to the terminals participating in the cooperative unlocking through various prior arts, which is not described in detail herein. The sending mode for sending various other information by the subsequent server may refer to various modes or combinations of the steps, and for brevity, the description is not repeated.

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

In this step, the server extracts the face image features of the face detected by the living body, and the adopted feature extraction method can also adopt any existing or future technology. And comparing the extracted face features with face features stored in advance. Because the authority users have at least two bits in the multi-person collaborative unlocking, at least two stored face features are realized. The server inquires the authority user associated with the lock of the identification number stored in the server in advance according to the identification number to be unlocked carried by the acquired face image, namely, the face characteristics of the authority user corresponding to the identification number are inquired. And comparing the acquired human face features with the human face features for realizing storage.

Specifically, each time a face image sent by one terminal is obtained, the image is compared with 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 comparison of the authorized user is successful or the verification passes to the authorized user or to the terminal participating in the collaborative unlocking. This may allow the user to learn about possible anomalies or risks by various means, such as by obtaining information about or the progress of the unlocking. For example, other non-authorized users perform unlocking operation, and the authorized user can know the information through the reserved information, so that the safety can be further improved.

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

Specifically, the server can set a progress bar according to the number of authorized users and the number of authenticated users, so that the unlocking progress can be visually displayed in the session. For example, when there are four authorized users, one of the facial image features is successfully compared, that is, when the verification passes, the current progress bar is displayed as a quarter progress bar.

Further, if the facial image features are compared with the preset stored N authorized users, the server considers that the face is not any authorized user according to the preset conditions, the authentication is considered to be failed, and the server can terminate unlocking at this moment. Accordingly, information can also be sent to authorized users or terminals participating in unlocking.

As for the preset condition that the server successfully or unsuccessfully compares the face features, the preset condition can be realized by a technology which is continuously updated 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, if the verification fails, the unlocking is stopped, and a message is sent. Of course, the server may compare the face image received each time with all the N authorized users. The invention is also not limited.

Step 150, when the comparison result indicates that all the face images acquired by the plurality of authorized users from the terminal by the server have consistent faces, the server sends an unlocking instruction.

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

According to the unlocking method, the facial image features sent by the terminal are extracted and compared with the stored facial features of the multiple authority users, and when all authority users have consistent faces in the facial images acquired from the terminal by the server, unlocking is performed, so that multi-user cooperative real-time remote unlocking is realized, the unlocking safety is guaranteed, and the requirements of on-line and real-time remote unlocking of various scenes are met.

In another specific embodiment, after acquiring the unlocking request, the server acquires the information of the associated right 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 information: unlocking progress, exception information, which may include one or more of: and living body detection failure information and face feature comparison failure information.

Further, in another specific embodiment, after the unlocking request is obtained, if the server does not send the unlocking instruction within the preset time, the unlocking is terminated, and the time limitation on the unlocking can reduce the risk and further improve the safety index.

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

step 210, a server acquires a registration request, wherein the registration request carries identification information of a lock to be encrypted; generally, when a user obtains a device lock, the user can download and install an application through a corresponding two-dimensional code, and when the user opens the application, the user can enter an initialization process of device configuration. After purchasing the lock, the settings the user has to make before decryption are the encryption settings. The lock device may be configured with a module or a port that accesses a network, for example, using WIFI as an example, the lock device may access a WIFI network or other networks in the present or future, and may specifically perform network configuration for the lock device through a terminal, for example, a mobile phone terminal or the like. The network configuration method and the hardware used in the method may adopt various prior arts, and the present application is not limited thereto.

After the network configuration of the lock device is successful, the terminal may 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 the lock devices managed by the server through the identified information, or the server itself may store the lock devices managed by the server, and may determine whether the lock belongs to the lock devices managed by the server according to the identified information.

Step 220, the server obtains at least two face images sent by at least one terminal, and the at least two face images are associated with the identifier of the to-be-encrypted lock; it can be understood that in a scenario where collaborative unlocking is required, at least two authority users can perform collaborative unlocking, that is, at least two authority users associated with one lock, so that in this step, the server obtains at least two face images sent by at least one terminal, and in order for the server to know which authority user is the received face image, the at least two face images may further carry an identifier of a lock to be encrypted, so that the at least two face images are associated with the identifier of the lock to be encrypted.

Step 230, the server performs living body detection on the at least two face images; in the step, the server performs living body detection on the received at least two face images. The living body detection can specifically adopt various existing technologies, including various anti-attack technologies and the like.

After the live body detection passes, the subsequent steps may be performed. When the acquired face image fails to pass the living body detection, the server may send a reminding message to the user or the terminal, and a specific reminding manner may refer to the embodiment corresponding to fig. 1. When the live detection fails, the server may terminate the encryption process and may further prompt the user to restart the encryption process.

Step 240, after the living body detection is passed, extracting the characteristics of the at least two face images; in this step, the server extracts the face image features of the face detected by the living body, and the adopted feature extraction method can also adopt any existing or future technology.

Step 250, establishing an association relationship between the identifier of the lock to be encrypted and the features of the at least two facial images, so that the users corresponding to the features of the at least two facial images are authorized users, and the authorized users can unlock the lock through the server;
