Description

Technical Field

[0001] The present disclosure relates to the field of application development technologies, and in particular, to a fingerprint data processing method and apparatus. Background Art

[0002] Currently, fingerprint recognition is a relatively common recognition method in biometric recognition. Therefore, many clients support the fingerprint recognition function. Through fingerprint recognition, various functions such as boot verification, payment verification, and login verification can be completed. Fingerprint template data is essential data in the fingerprint recognition process. The fingerprint template data may include fingerprint data of multiple legitimate users stored. During the fingerprint recognition process, when the fingerprint data obtained by the client matches any of the fingerprint data in the fingerprint template data, it can be determined that the user corresponding to the obtained fingerprint data is one of the multiple legitimate users.

[0003] In the related art, the fingerprint template data is often stored at a preset location in the client. However, in some cases, during the fingerprint recognition process of the client, the preset location for storing the fingerprint template data is often inaccessible, resulting in difficulty in completing fingerprint recognition on the client.

[0004] Therefore, there is an urgent need for a fingerprint data processing method in the related art to enable the client to successfully obtain the fingerprint template data during the fingerprint recognition process. Summary of the Invention

[0005] To overcome the problems existing in the related art, the present disclosure provides a fingerprint data processing method and apparatus.

[0006] According to a first aspect of an embodiment of the present disclosure, there is provided a fingerprint data processing method, including:

[0007] Determine whether the operating system of the client has been upgraded to a specified version;

[0008] If the determination result is yes, copy the fingerprint template data from the first data partition to the second data partition, where the second data partition is a data storage area accessible during fingerprint recognition in the client.

[0009] According to a second aspect of an embodiment of the present disclosure, there is provided a fingerprint data processing apparatus, including:

[0010] A determination module, configured to determine whether the operating system of the client has been upgraded to a specified version;

[0011] A data copy module, configured to, if the determination result is yes, copy the fingerprint template data from the first data partition to the second data partition, where the second data partition is a data storage area accessible during fingerprint recognition in the client.

[0012] According to a third aspect of embodiments of the present disclosure, there is provided a fingerprint data processing device, including:

[0013] A processor;

[0016] According to a fourth aspect of embodiments of the present disclosure, there is provided a non-transitory computer-readable storage medium, which, when the instructions in the storage medium are executed by a processor, enables the processor to execute the fingerprint data processing method.

[0017] The technical solutions provided by the embodiments of the present disclosure may include the following beneficial effects: For the fingerprint data processing methods provided by various embodiments of the present disclosure, when the fingerprint template data in the first data partition cannot be accessed after the client operating system is upgraded to a specified version, when it is detected that the operating system of the client is upgraded to the specified version, the fingerprint template data is copied from the first data partition to the second data partition, and the second data partition is a data storage area accessible during fingerprint recognition in the client. In this way, not only can the fingerprint recognition function of the client be unaffected by the client operating system, but even if the client operating system is downgraded to a previous version, the normal access to the fingerprint template data can still be ensured.

[0025] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all the implementation manners consistent with the present disclosure. On the contrary, they are only examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0026] To facilitate the understanding of the technical solutions provided in the embodiments of the present application by those skilled in the art, the technical environment for implementing the technical solutions will be described first below.

[0027] For versions before Android 8.0 (referred to as Android 8.0 for short), the upgrade of the operating system (such as upgrading from Android 6.0 to Android 7.0) often takes a long time. Usually, after Google releases a new version of the Android Open-Source Project (AOSP), the SoC manufacturer needs to upgrade the Hardware Abstraction Layer (HAL), and the OEM manufacturer needs to upgrade the HAL and the system framework before the user can receive the push of the Over-the-Air Technology (OTA) upgrade package on the client. Even lower-end products will not be upgraded with the operating system after leaving the factory. To solve the above problems, Google proposed the Project Treble project in Android 8.0. In the Project Treble project, the system framework and the HAL can be separated and designed. In Android 8.0, based on the Hardware Interface Definition Language (HIDL), the system framework can be updated without rebuilding the HAL. Through the separated design of the system framework and the HAL, it also enables the Android system after Android 8.0 to directly upgrade the system framework without considering the changes in the HAL layer when upgrading, thereby shortening the time for the user device to receive the OTA push for system upgrade.

[0028] In Android 8.0 and later versions, the HAL can be built by the vendor or the SOC manufacturer and stored in the vendor data partition of the client. In this way, the system framework can be updated and replaced through OTA in the vendor data partition without recompiling the HAL. However, the separation of the system framework and the HAL may lead to restrictions on data access permissions. For example, for the fingerprint template data required during the fingerprint recognition process, in versions before Android 8.0, the fingerprint template data was stored in the system data partition, while in Android 8.0 and later versions, the storage path of the fingerprint template data was modified to the vendor data partition. As a result, in Android 8.0 and later versions, the fingerprint template data in the system data partition cannot be accessed, and thus, after the client operating system is upgraded, the user cannot complete the fingerprint verification.

[0029] Based on the above technical requirements, the fingerprint data processing method provided by the present disclosure can copy the fingerprint template data source from the system data partition to the vendor data partition when it is detected that the operating system of the client is upgraded to a specified version. In this way, the fingerprint template data can be accessed in Android 8.0 and later versions.

[0030] The fingerprint data processing method described in the present disclosure will be described in detail below with reference to the accompanying drawings. Figure 1 It is a flowchart of a method of an embodiment of the fingerprint data processing method provided by the present disclosure. Although the present disclosure provides method operation steps as shown in the following embodiments or drawings, more or fewer operation steps may be included in the method based on routine or non-creative labor. In steps where there is no necessary causal relationship logically, the execution order of these steps is not limited to the execution order provided in the embodiments of the present disclosure.

[0031] Specifically, an embodiment of the fingerprint data processing method provided by the present disclosure is as Figure 1 shown and may include:

[0032] In step 101, it is determined whether the operating system of the client is upgraded to a specified version;

[0033] In step 103, if the determination result is yes, the fingerprint template data is copied from the first data partition to the second data partition, where the second data partition is the data storage area accessible during fingerprint recognition in the client.

[0034] The fingerprint data processing method provided by the present disclosure can be applied to any client with an operating system, and the operating system includes but is not limited to Android operating system, iOS, Windows, etc. The client can include various electronic devices such as mobile smart phones, computers (including laptops and desktop computers), tablet electronic devices, personal digital assistants (PDAs), or smart wearable devices, etc.

[0035] In an embodiment of the present disclosure, the client can detect whether the operating system is upgraded to a specified version. In one embodiment, the specified version can include Android operating system version 8.0. Of course, the specified version is not limited to the Android operating system version 8.0. In any application scenario where the client cannot access the fingerprint template data in the old version due to the version upgrade of the operating system, the fingerprint data processing method provided by the embodiments of the present disclosure can be used. If the judgment result is that the operating system of the client is upgraded to the specified version, the fingerprint template data is copied from the first data partition to the second data partition, where the second data partition is the data storage area accessible during fingerprint recognition in the client.

[0036] In one example, the first data partition can include the system partition in the Android operating system, and the second data partition can include the vendor data partition. In Android 8.0 and later versions, the separation of the system framework and HAL results in the separation of the data access permissions of their corresponding data partitions (i.e., the system data partition and the vendor data partition). Based on this, the fingerprint template data stored in the system data partition can be copied to the vendor data partition, so that during the fingerprint recognition process of the client, the historical fingerprint template data stored in the client can be normally accessed.

[0037] In an embodiment of the present disclosure, if the judgment result is that the operating system of the client is upgraded to the specified version, the fingerprint template data can be copied from the first data partition to the second data partition when the fingerprint template data needs to be loaded. That is, when it is detected that the operating system of the client is upgraded to the specified version and when the fingerprint template data needs to be loaded, the fingerprint template data is copied from the first data partition to the second data partition. Of course, in other embodiments, the fingerprint template data can also be copied from the first data partition to the second data partition at any time after detecting that the operating system of the client is upgraded to the specified version and before loading the fingerprint template data. The present disclosure does not limit the time for copying the fingerprint template data.

[0038] In an embodiment of the present disclosure, as Figure 2 shown, in the process of copying the fingerprint template data from the first data partition to the second data partition, it can include:

[0039] In step 201, determine the first storage path of the fingerprint template data in the first data partition;

[0040] In step 203, create a second storage path in the second data partition;

[0041] In step 205, copy the fingerprint template data in the first storage path to the second storage path.

[0042] In an embodiment of the present disclosure, during the process of copying the fingerprint template data from the first data partition to the second data partition, the first storage path of the fingerprint template data in the first data partition may be determined first. In one example, according to the definition of the Android operating system, the storage path of the fingerprint template data in the system data partition may be / data / system / $userId / fpdata. Then, a second storage path may be created in the second data partition. In the above example, a second storage path / data / vendor_de / $userId / fpdata may be created in the vendor data partition to store the fingerprint template data. Wherein, the second storage path may be the storage path defined by the updated operating system, or may be an arbitrarily created storage path by the client, and the present disclosure does not limit this here. Finally, the fingerprint template data in the first storage path may be copied to the second storage path.

[0043] In an embodiment of the present disclosure, when the fingerprint template data in the first data partition is updated, the fingerprint template data in the second data partition may also be synchronously updated. Specifically, as Figure 3 shown, it may include:

[0044] In step 301, determine whether the fingerprint template data in the first data partition is updated;

[0045] In step 303, if the judgment result is yes, synchronously update the updated data of the fingerprint template data in the first data partition to the fingerprint template data in the second data partition.

[0046] In one example, during the use of Android 8.0 and later versions, if the client updates the fingerprint template data, the update operation may include, for example, deletion, addition, etc. Based on this, it can be determined whether the fingerprint template data in the first data partition is updated. If the judgment result is that the fingerprint template data in the first data partition is updated, then the updated data in the fingerprint template data in the first data partition is synchronously updated to the fingerprint template data in the second data partition.

[0047] The fingerprint data processing method provided by each embodiment of the present disclosure can copy the fingerprint template data from the first data partition to the second data partition when it is detected that the operating system of the client is upgraded to the specified version, in the case where the fingerprint template data in the first data partition cannot be accessed after the client operating system is upgraded to the specified version. The second data partition is a data storage area accessible during fingerprint recognition on the client. In this way, not only can the fingerprint recognition function of the client be unaffected by the client operating system, but even if the client operating system is downgraded to a previous version, the normal access to the fingerprint template data can be ensured.

[0048] On the other hand, the present disclosure also provides a fingerprint data processing device.

[0049] The judgment module 401 is used to judge whether the operating system of the client is upgraded to the specified version;

[0050] The data replication template 403 is used to copy the fingerprint template data from the first data partition to the second data partition if the judgment result is yes, where the second data partition is a data storage area accessible during fingerprint recognition on the client.

[0051] Optionally, in an embodiment of the present disclosure, the data replication template includes:

[0052] The data replication sub-template is used to copy the fingerprint template data from the first data partition to the second data partition when the judgment result is yes and when the fingerprint template data needs to be loaded.
