detailed description

In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present specification, the technical solutions in the embodiments of the present specification will be described in detail in conjunction with the drawings in the embodiments of the present specification. Obviously, the described implementation Examples are only a part of the embodiments of this specification, but not all the embodiments. Based on the embodiments in this specification, all other embodiments obtained by those of ordinary skill in the art should fall within the scope of protection.

In the current technology, in order to protect user privacy and facilitate management, the user's biometrics are generally called through the operating system to record and save the corresponding hardware module, and the application program does not have permission to directly call the user's biometrics. That is, the user's biometric information and the application are isolated. The biological features include fingerprints, irises, voice prints, facial features, and so on. The operating system can be an Android system or an IOS system.

When any local application needs to use the user's biometrics for authentication, it can request biometric information about the user by requesting the operating system. As shown in FIG. 1, FIG. 1 is a schematic diagram of the architecture of an application program, an operating system, and device hardware when biometrics are involved in the current technology. The user equipment in the schematic diagram may be a device such as a smart phone, a tablet computer, etc., and the collection hardware therein may include hardware such as a fingerprint collection module, a camera, a microphone, and so on.

Therefore, when it is necessary to use the user's biometrics to verify a function in the application, for example, to enable fingerprint payment or face login, if the user's biometrics have not been entered in the operating system in advance, then the application It is impossible to call to the operating system. In this case, the user first needs to leave the current application interface and switch to the corresponding entry interface of the operating system, enter the biometrics, and then switch back to the application to enable fingerprint payment or face login.

Based on this, the embodiments of the present specification provide a solution for enabling biometric application functions. By directly embedding the relevant functions of the operating system in the application, the user does not need to switch out the application interface when the user has not entered the biometrics. Can open the biometric application function in the application.

The technical solutions provided by the embodiments of this specification will be described in detail below in conjunction with the drawings. As shown in FIG. 2, FIG. 2 is a schematic flowchart of a method for enabling a biometric application function provided by an embodiment of the present specification. The process specifically includes the following steps:

S201. The application program receives a confirmation instruction input by the user to start the biometric application function.

The biometric application function may be login, unlock, or payment. In the application program interface, corresponding setting items can be displayed to provide users with a choice of whether to turn on or off a certain biometric application function.

S203. The application program initiates whether the operating system has previously recorded the user's biometrics.

As mentioned earlier, since the user's biometrics are entered and managed by the operating system, the application does not have the right to directly touch the user's biometrics.

Therefore, in one embodiment, the application program may initiate the detection, and the method for performing the detection may be that the application program initiates a query request to the operating system. In the operating system, the flag bit can be preset to mark whether the operating system has registered the specified biometrics. The value of the flag bit indicates "yes" or "no". For example, the default value of the flag bit is set to "0", which is used to indicate that there is no fingerprint. After the user has entered the fingerprint, the value of the flag bit is modified to "1". After the user deletes the fingerprint, Change the value of the flag to "0" again. Therefore, the operating system can directly query the value of the flag bit to determine whether the operating system has recorded user biometrics.

After receiving the query request, the operating system can directly query the value of the flag bit, so as to determine whether the operating system has previously recorded the user's biometrics and obtain the detection result.

In another embodiment, the application may also query some files related to the user's biometrics that can be accessed. For example, in the case where the user's biometrics have been entered in the operating system in advance, at this time, if the application needs it, the operating system can send some files or information related to the user's biometrics to the application, for example, send a The irreversible key file (for example, hash value) generated by the biometrics is sent to the application program, and the application program receives the irreversible key file and stores it to the specified path.

The irreversible key file means that the file is generated using an irreversible encryption algorithm for the user's biometrics, and the user's biometrics cannot be reversed based on the irreversible key file to ensure that the user's privacy will not be revealed. The irreversible encryption algorithm may be the MD5 (Message-Digest Algorithm 5) algorithm or the irreversible encryption standard (Secure Hash Standard, SHS), etc. Due to the uniqueness of the user's biological characteristics, the irreversible key file is also generally unique.

In this embodiment, the application can directly query whether there is a corresponding irreversible key file in the specified path. If so, it means that the system has already entered the user's biometrics. Otherwise, it has not been entered yet.

S205. In the case of a negative detection result, the operating system calls the biometric input function, and keeps the interface of the application displayed on the front end, and displays a prompt interface related to the biometric input function to obtain the user Biological characteristics.

As mentioned earlier, the operating system can directly obtain the detection result, or the application program can notify the operating system of the detection result. In the case that the detection result is negative, the operating system calls the biometric input function, and while keeping the interface of the application displayed on the front end, the operating system displays a prompt interface related to the biometric input function to obtain the user's Biological characteristics. The prompt interface generally displays only some prompt information related to the entry process. The entry process can be implemented by the operating system calling the corresponding fingerprint collection module, camera, microphone, etc. hardware.

The specific display method may be to embed the above prompt interface in the interface of the application, or to suspend the above prompt interface in the interface of the application, or to display the above prompt interface and the interface of the application in split screens. As shown in FIG. 3, FIG. 3 is a schematic diagram of a prompt interface displayed in an application program interface provided by an embodiment of the present specification. In this diagram, the prompt interface is embedded at the bottom of the interface of the application.

It should be noted that, in this process, although the interface of the application is still displayed on the front end, the application itself will not participate in the process of biometric input. Enter the biometrics

It is also saved by the operating system, and corresponding access permissions are set, for example, only the operating system has read and delete permissions.

In addition, in this process, the entered biometrics may also be part of the user feature information, as long as the part of the user feature information can be used to uniquely identify the user. For example, a fingerprint refers to a line formed by unevenness on the skin on the front of the end of a human finger. The lines are regularly arranged to form different patterns. The start point, end point, junction point and bifurcation point of the line are called the characteristic points of the fingerprint. During the process of entering the fingerprint, the full picture of the fingerprint is not entered, but only the above characteristic points. This can also play the role of identifying the user, and even if other people or applications obtain the feature point, there is no way to reverse the fingerprint image, further protecting user privacy.

S207: After the application program confirms that the biometric function of the operating system is successfully entered, the user's biometric application function is enabled.

After the biometric function is successfully entered, the operating system can send a confirmation message to the application. After receiving the confirmation message, the application can know that it has been successfully entered, and open the biometric application function specified in the confirmation instruction in the application program. .

In one embodiment, after the biometric function is successfully entered, the operating system may directly generate an irreversible key file using an irreversible encryption algorithm according to the user's biometrics. And send the message of successful entry and the irreversible key file to the application, or just send the irreversible key file to the application. The application can know that it has been successfully entered. And save the irreversible key file, the next time you log in, unlock or pay according to the user's biological characteristics, you can perform user identity verification according to the irreversible key file, while also ensuring that the application will not leak user privacy.
