[0002] The current Android system's fingerprint recognition module has the following issues in its software and algorithm initialization configuration:

[0003] 1. The initial configuration is compiled directly into the static library, which means that the static library needs to be updated every time there is a modification.

[0004] 2. After updating the static library, you also need to recompile the trusted execution environment.

[0005] 3. This method results in a cumbersome and time-consuming parameter update and debugging process.

[0024] To make the objectives, advantages, and features of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the drawings are all in a very simplified form and are not drawn to scale, and are only used to facilitate and clarify the explanation of the embodiments of this invention. Furthermore, the structures shown in the drawings are often part of the actual structures. In particular, different figures may emphasize different aspects and may sometimes use different scales.

[0025] As used in this invention, the singular forms “a,” “an,” and “the” include plural objects; the term “or” is generally used to mean “and / or”; the term “a number” is generally used to mean “at least one”; and the term “at least two” is generally used to mean “two or more”. Furthermore, the terms “first,” “second,” and “third” are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as “first,” “second,” or “third” may explicitly or implicitly include one or at least two of that feature. “One end” and “the other end,” as well as “proximal end” and “distal end,” generally refer to two corresponding parts, including not only endpoints. The terms “installed,” “connected,” and “joined” should be interpreted broadly, for example, as a fixed connection, a detachable connection, or an integral part; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or a connection within two elements or an interaction between two elements. Furthermore, as used in this invention, the phrase "one element is disposed on another element" generally only indicates that there is a connection, coupling, cooperation, or transmission relationship between the two elements, and the connection, coupling, cooperation, or transmission between the two elements can be direct or indirect through an intermediate element. It should not be construed as indicating or implying a spatial positional relationship between the two elements, i.e., one element can be located arbitrarily inside, outside, above, below, or to one side of the other element, unless otherwise explicitly stated. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0026] The core idea of ​​this invention is to provide a configuration management method to solve the problem that the initial configuration process of fingerprint recognition modules in the prior art is relatively cumbersome.

[0027] The following description refers to the accompanying drawings.

[0028] Please refer to Figure 1 This embodiment provides a configuration management method, which is applied to the configuration process of a fingerprint recognition module. The configuration management method includes:

[0029] S10, the configuration file is stored in a preset storage location on the CA (Client Application, which is also called the CA side on most mobile phones. This is a general term, and in this embodiment, it can be understood as the Android system).

[0030] S20, Obtain the new configuration file from external input and replace the old configuration file at the preset storage location.

[0031] S30, CA preprocessing configuration file. Specifically, it includes at least one of the following steps: loading the configuration file, reading the configuration file, converting the configuration file, and parsing the configuration file.

[0032] S40, the CA passes the configuration information in the configuration file to the TA (Trusted Application, which is the TEEOS side, a small OS independent of the Android system). This passing can include, for example, directly transmitting data to the receiving end, or, for example, passing information from the data through a triggered event. The carrier of the configuration information can be data or other states, such as voltage.

[0033] And, in step S50, the TA completes the initialization process of the fingerprint recognition module based on the received configuration information. A transmission operation is performed after each power-on or power-up, determined by the current architecture of the CA and TA. If the configuration is updated, the configuration file on the CA side is updated, and the parameters are updated upon the next power-on. Of course, in one embodiment, debugging functionality is retained; during troubleshooting, the configuration file on the CA side is updated in real time, and the transmission operation is performed.

[0034] The comparison of this configuration with existing technology solutions is shown in Table 1.

[0035] Table 1 Comparison of existing technologies and solutions in this embodiment.

[0036]

[0037] As shown in Table 1, in the prior art, when the configuration needs to be updated, the static library and TA need to be recompiled. Therefore, the flexibility and debugging efficiency are far lower than the solution provided in this embodiment.

[0038] In step S10, the step of storing the configuration file at a preset storage location on the CA side includes: storing the configuration file in encrypted form at the preset storage location; correspondingly, the step of CA preprocessing the configuration file includes: decoding the configuration file. This configuration, considering the special characteristics of the fingerprint recognition module, improves its security level and reduces the possibility of data tampering.

[0039] In another embodiment, the configuration file is stored in a preset storage location on the CA side, the preset storage location being used to store at least two copies of the configuration file; a new configuration file input from an external source is obtained and stored in the preset storage location, while the old configuration file is retained; and, by default, the configuration information in the latest configuration file is always transmitted; when an external loading control command intervenes, the configuration information in the specified configuration file is transmitted.

[0040] This configuration helps retain parameters that were previously working correctly, preventing the fingerprint recognition module from malfunctioning due to problems with the new configuration file (such as encoding failure or configuration errors), and also facilitating debugging.

[0041] Please refer to Figure 2 The configuration management method further includes: CA verifying the configuration file; if verification is successful, CA transmits the configuration information to TA. CA verifies the configuration file; if verification fails, error handling is performed. Error handling includes: stopping the fingerprint recognition module, rereading, and reporting an error. Alternatively, if verification fails, no error handling may be performed; for example, configuration information may not be transmitted, and the TA will still complete initialization according to the original configuration parameters.

[0042] Step S40, in which the CA transmits the configuration information from the configuration file to the TA, includes: transmitting data based on the command interface and a shared cache. During this process, the configuration information is temporarily stored in the shared cache as data to ensure the security of the transmission.

[0043] Please continue to refer to this. Figure 2 The configuration management method further includes: the TA verifying the received configuration information; if the verification is successful, the TA completes the initialization process of the fingerprint recognition module based on the received configuration information.

[0044] Preferably, the step of TA verifying the received configuration information includes at least one of the following steps: checking the signature of each data item, checking the ID, checking the version information, and checking the overall magic number and length. The magic number refers to the number in special positions such as check bits and error correction bits.

[0045] The configuration management method further includes: the TA verifying the received configuration information; if verification fails, the TA completes the initialization process of the fingerprint recognition module based on the default parameters in the static library. With this configuration, even if configuration data transmission fails, or if the CA does not transmit data, some fingerprint recognition functions can still operate.

[0046] In step S50, the initialization process of the fingerprint recognition module includes: loading initialization parameters, setting recognition thresholds, calibrating recognition algorithms, etc.

[0047] This embodiment has the following beneficial effects:

[0048] 1. Significantly reduced the number of times static libraries and TA need to be recompiled when updating initialization parameters.

[0049] 2. Significantly improved the efficiency of parameter debugging and optimization.

[0050] 3. It enhances the system's flexibility, allowing it to quickly adapt to different hardware configurations or changes in requirements.

[0051] 4. It simplifies the development and maintenance process and reduces potential human error.

[0052] 5. It shortened the product development cycle and accelerated market response speed.

[0053] 6. Reduced development and maintenance costs.

[0054] In summary, this embodiment provides a configuration management method, including: CA preprocessing a configuration file; CA transmitting the configuration information in the configuration file to TA; and TA completing the initialization process of the fingerprint recognition module based on the received configuration information. This configuration, by dynamically loading and updating the configuration content of the fingerprint recognition module, significantly reduces the number of recompilations required when updating initialization parameters, improves the efficiency of parameter debugging and optimization, enhances system flexibility, and solves the problem of cumbersome initialization configuration processes for fingerprint recognition modules in existing technologies.
