For convenience of description, the above-mentioned devices are collectively referred to as a mobile terminal. The following describes embodiments of the present invention in detail.
Referring to fig. 1, fig. 1 is a schematic flowchart of a fingerprint template synchronization method provided in an embodiment of the present invention, and is applied to a mobile terminal equipped with an android system, where the mobile terminal includes a fingerprint security system and a fingerprint template database, and as shown in the figure, the fingerprint template synchronization method includes:
s101, the mobile terminal calls a fingerprint service of an android system to acquire fingerprint synchronization data, wherein the fingerprint synchronization data comprise N fingerprint Identifications (ID) corresponding to N fingerprint templates in a fingerprint security system (Trust Zone, TZ), and N is a positive integer.
In one possible example, the acquiring fingerprint synchronization data includes: fingerprint synchronous data sent by a fingerprint Trusted Application (TA) is acquired.
When the fingerprint is applied in a trusted manner, the fingerprint is applied in a trusted manner in applications supported by a secure operating system corresponding to a Trusted Execution Environment (TEE) of the mobile terminal. The TEE provides a secure execution environment for the trusted application TA while also protecting the TA's resources and data confidentiality, integrity and access rights. To guarantee the root of trust of the TEE itself, the TEE is authenticated and isolated from the android operating system during secure boot. In TEE, each TA is independent of each other and cannot access each other without authorization.

In one possible example, a specific implementation manner of synchronizing the fingerprint template in the fingerprint template database according to the comparison result between the M fingerprint IDs and the N fingerprint IDs by the FingerprintService of the mobile terminal is as follows:
when the M fingerprint IDs do not comprise a first fingerprint ID in the N fingerprint IDs, the first fingerprint ID is created in the fingerprint template database, and a first fingerprint template corresponding to the first fingerprint ID is stored; and/or
And when a second fingerprint ID in the M fingerprint IDs does not belong to the N fingerprint IDs, deleting the second fingerprint ID in the fingerprint template database and a second fingerprint template corresponding to the second fingerprint ID.

In this possible example, a specific implementation manner of the mobile terminal entering the third fingerprint template in the fingerprint security system may be:
when a fingerprint is input, the application of the mobile terminal firstly sends an instruction to the fingerprint TA to acquire a challenge factor, the fingerprint TA transmits the generated challenge factor back to the FingerprintService, and the FingerprintService further transmits the challenge factor back to the application; the application uses the challenge factor to send an instruction to the fingerprint TA to obtain a first check identifier token, the fingerprint TA checks the challenge factor transmitted by the application, and if the check result is correct, a second check identifier token is generated and transmitted back to the application; after the application acquires the first check identifier token, the first check identifier token is used as a parameter to send an entry instruction to the fingerprint TA, and the fingerprint TA starts an entry process after detecting that the first check identifier token and the second check identifier token are successfully matched; when the L-th entry (assuming that L entries are required for the fingerprint), the fingerprint TA saves a third fingerprint template in the fingerprint security system and generates a third fingerprint ID.
In one possible example, before the acquiring the fingerprint synchronization data, the method further comprises:
receiving a fingerprint template deleting request sent by a fingerprint TA, wherein the fingerprint template adding request carries a fourth fingerprint ID, and the fingerprint security system does not comprise a fourth fingerprint template corresponding to the fourth fingerprint ID;
and deleting the fourth fingerprint ID and a fourth fingerprint template corresponding to the fourth fingerprint template in the fingerprint template database.
In this possible example, the specific implementation manner of the mobile terminal deleting the fourth fingerprint template in the fingerprint security system may be: and the application of the mobile terminal sends an instruction for deleting the fourth fingerprint ID to the fingerprint TA, and the fingerprint TA deletes the fourth fingerprint template corresponding to the fourth fingerprint ID in the fingerprint security system after receiving the instruction.

s202, the mobile terminal calls a fingerprint service to compare M fingerprint IDs corresponding to M fingerprint templates in a fingerprint template database with the N fingerprint IDs, wherein M is a positive integer;
s203, the mobile terminal calls the fingerprint service to create the first fingerprint ID in the fingerprint template database when the first fingerprint ID in the N fingerprint IDs is not included in the M fingerprint IDs, and stores the first fingerprint template corresponding to the first fingerprint ID.
It can be seen that, in the embodiment of the present invention, the mobile terminal first acquires the fingerprint synchronization data, where the fingerprint template synchronization data includes N fingerprint identifiers ID corresponding to N fingerprint templates in the fingerprint security system, secondly, comparing M fingerprint IDs corresponding to M fingerprint templates in the fingerprint template database with N fingerprint IDs, and finally, when the first fingerprint ID in the N fingerprint IDs is not included in the M fingerprint IDs, a first fingerprint ID is created in the fingerprint template database, and a first fingerprint template corresponding to the first fingerprint ID is stored, thereby saving the third fingerprint template stored in the missing fingerprint security system in the fingerprint template database to the fingerprint template database, the fingerprint security system of the mobile terminal and the fingerprint template in the fingerprint template database are synchronized, and the application accuracy of the fingerprint template is improved.
Referring to fig. 3, fig. 3 is a schematic flowchart of another fingerprint template synchronization method provided by the embodiment of the present invention, and is applied to a mobile terminal equipped with an android system, where the mobile terminal includes a fingerprint security system and a fingerprint template database, and as shown in the figure, the fingerprint template synchronization method includes:

s302, the mobile terminal calls the fingerprint service to compare M fingerprint IDs corresponding to M fingerprint templates in a fingerprint template database with the N fingerprint IDs, wherein M is a positive integer;
s303, the mobile terminal calls a fingerprint service, and when the second fingerprint ID in the M fingerprint IDs does not belong to the N fingerprint IDs, the mobile terminal deletes the second fingerprint ID in the fingerprint template database and a second fingerprint template corresponding to the second fingerprint ID.
It can be seen that, in the embodiment of the present invention, the mobile terminal first acquires fingerprint synchronization data, where the fingerprint synchronization data includes N fingerprint identification IDs corresponding to N fingerprint templates in the fingerprint security system, then compares M fingerprint IDs corresponding to M fingerprint templates in the fingerprint template database with the N fingerprint IDs, and finally deletes the second fingerprint ID in the fingerprint template database and the second fingerprint template corresponding to the second fingerprint ID when it is determined that the second fingerprint ID in the M fingerprint IDs does not belong to the N fingerprint IDs, so as to delete the fourth fingerprint template which is redundant in the fingerprint template database and not stored in the fingerprint security system, thereby implementing synchronization between the fingerprint security system of the mobile terminal and the fingerprint template in the fingerprint template database, and facilitating improvement of accuracy of application of the fingerprint template.
