An embodiment of the present invention provides a fingerprint verification method for pre-matching a fingerprint database, and referring to fig. 2, fig. 2 is a flowchart illustrating a first embodiment of a fingerprint verification method for pre-matching a fingerprint database according to the present invention.
In this embodiment, the fingerprint verification method for pre-matching a fingerprint database includes the following steps:
step S10: and when the fingerprint to be authenticated is detected, acquiring fingerprint verification information of the fingerprint to be authenticated.
It should be noted that the execution subject of this embodiment is a terminal, and the terminal may be a terminal based on an android system, such as a smart phone, a tablet computer, and the like, which can detect and identify a fingerprint, or other devices capable of implementing this function, which is not limited in this embodiment.
It should be understood that the basic flow for the application of fingerprint identification technology at present is: when receiving the fingerprint needing authentication and matching, only traversing the array to open different fingerprint libraries in turn to match the corresponding fingerprint, and the method occupies CPU resources, has low matching efficiency, depends on the judgment of the internal program (non-open source code) of the fingerprint library whether the matching is successful, is relatively single, and opens the fingerprint library all the time without traversing when the matching in the fingerprint internal library is wrong and the error is not returned all the time, thereby using the fingerprint library as the correct fingerprint and causing the fingerprint to be incapable of being used normally. According to the scheme of the embodiment, the fingerprint verification information based on the fingerprint to be authenticated is firstly screened, the target fingerprint library is determined under the condition that the preset fingerprint library is not opened, and the target fingerprint library is opened to match and authenticate the fingerprint to be authenticated, so that the preset fingerprint libraries do not need to be opened in sequence, CPU (central processing unit) resources are saved, and the matching efficiency is improved.
In specific implementation, the fingerprint to be authenticated may be collected by a fingerprint collection device connected to the terminal, and the fingerprint collection device may be any device capable of implementing the function. When the fingerprint to be authenticated is detected, the following steps are carried out: when the fingerprint information input by the user is collected by the fingerprint collecting device, the input fingerprint information is used as the fingerprint to be authenticated.
It should be noted that the fingerprint verification information includes, but is not limited to, configuration information to be authenticated and fingerprint content information of the fingerprint to be authenticated, and there may be other related information about the fingerprint to be authenticated, for example: the recording time and the recording area of the fingerprint to be authenticated and the like.
Step S20: and traversing a preset fingerprint library according to the fingerprint verification information, and performing internal matching on the preset fingerprint library to determine a target fingerprint library.
It should be understood that traversing the preset fingerprint library according to the fingerprint verification information, performing internal matching of the preset fingerprint library, to determine the target fingerprint library refers to: the fingerprint authentication method comprises the steps of extracting to-be-authenticated configuration information and fingerprint content information of a to-be-authenticated fingerprint according to fingerprint authentication information, firstly comparing the to-be-authenticated configuration information with prestored configuration file information stored in an equipment file system, then comparing the fingerprint content information with each preset fingerprint library to determine whether the to-be-authenticated fingerprint is a configured fingerprint, and when the two comparisons are successful, using the traversed and matched preset fingerprint library as a target fingerprint library.
It should be noted that the operation of traversing the array is implemented by traversing the array through the offset pointer based on the for loop.
Step S30: and matching the fingerprint to be authenticated based on the target fingerprint database.
In specific implementation, after the target fingerprint library is determined, the hw _ get _ module function is called to acquire and open the target fingerprint library, so that the fingerprint to be verified can be matched and authenticated in the target fingerprint library.
In the embodiment, when the fingerprint to be authenticated is detected, the fingerprint verification information of the fingerprint to be authenticated is acquired; traversing a preset fingerprint database according to the fingerprint verification information, and performing internal matching on the preset fingerprint database to determine a target fingerprint database; and matching the fingerprint to be authenticated based on the target fingerprint database. By the method, when the fingerprint to be authenticated is detected, the preset fingerprint libraries are traversed according to the fingerprint verification information of the fingerprint to be authenticated, so that after the target fingerprint library is determined in a matching mode, the target fingerprint library is directly opened to match the fingerprint to be authenticated, the fingerprint to be authenticated does not need to be sequentially opened to compare and match the fingerprint to be authenticated, and the method is simpler, more convenient and quicker.
Referring to fig. 3, fig. 3 is a flowchart illustrating a fingerprint verification method for pre-matching a fingerprint database according to a second embodiment of the present invention.
Based on the first embodiment, the fingerprint verification method for pre-matching a fingerprint database in this embodiment includes, in step S20:
step S201: and determining the configuration information to be authenticated and the fingerprint content information of the fingerprint to be authenticated according to the fingerprint verification information.
It should be noted that the configuration information to be authenticated refers to the device file corresponding to the fingerprint to be authenticated, and the fingerprint content information refers to the fingerprint content of the fingerprint to be authenticated, that is, the related information of the fingerprint body, for example: fingerprint lines, etc.
Step S202: and calling a plurality of pre-stored preset fingerprint libraries.
It should be understood that the preset fingerprint library refers to: the fingerprint database is pre-stored in a hard disk or a storage space, and comprises a plurality of fingerprint libraries which are configured and store fingerprints. The number of the preset fingerprint database may be any number, and is preset by the user, which is not limited in this embodiment.
Step S203: and matching each preset fingerprint database according to the configuration information to be authenticated and the fingerprint content information to determine a target fingerprint database.
In specific implementation, traversing each preset fingerprint database according to the configuration information to be authenticated and the fingerprint content information to determine a target fingerprint database refers to: firstly, comparing the configuration information to be authenticated with prestored configuration file information stored in an equipment file system, then comparing the fingerprint content information with each preset fingerprint library to determine whether the fingerprint is a configured fingerprint, and when the two comparisons are successful, using the traversed and matched preset fingerprint library as a target fingerprint library.
Further, in order to accurately determine the target fingerprint database, step S203 includes: acquiring pre-stored configuration file information stored in an equipment file system; comparing the configuration information to be authenticated with the pre-stored configuration file information to obtain a first comparison result; and when the first comparison result is that the comparison is successful, matching each preset fingerprint database according to the fingerprint content information to determine a target fingerprint database.
It should be noted that, acquiring the pre-stored profile information stored in the device file system refers to: and acquiring prestored configuration file information in a device file system, wherein the device file system refers to a devfs device file system for managing/dev directories, and the prestored configuration file information refers to a configuration file corresponding to fingerprints which are already stored in the device file system.
It should be understood that, comparing the configuration information to be authenticated with the pre-stored configuration file information to obtain a first comparison result means: and comparing the configuration information to be authenticated with prestored configuration file information stored in an equipment file system to determine whether the equipment file corresponding to the fingerprint in devfs exists or not, wherein the final result is a first comparison result.
In a specific implementation, when the first comparison result is that the comparison is successful, matching each preset fingerprint database according to the fingerprint content information to determine a target fingerprint database refers to: and when the first comparison result is that the comparison is successful, judging that the configuration file corresponding to the fingerprint to be authenticated exists in the equipment file system, and traversing each preset fingerprint library according to the fingerprint content information to determine the target fingerprint library from all the preset fingerprint libraries.
Through this kind of mode, realized judging whether the equipment file that corresponds the fingerprint in devfs exists, reduced the number of times of opening the fingerprint storehouse, quick accurate fingerprint module to the current hardware installation of matching.
Further, in order to accurately compare the fingerprint contents, matching each preset fingerprint database according to the fingerprint content information to determine a target fingerprint database includes: acquiring prestored fingerprint information of each preset fingerprint library; and determining a target fingerprint database from each preset fingerprint database according to the fingerprint content information and the pre-stored fingerprint information.
It should be noted that the pre-stored fingerprint information refers to the related information of the fingerprint stored in each preset fingerprint library and having the corresponding configuration file. Then, determining the target fingerprint database from each preset fingerprint database according to the fingerprint content information and the pre-stored fingerprint information refers to comparing the fingerprint content information with the pre-stored fingerprint information in each preset fingerprint database, so as to determine which preset fingerprint database the fingerprint to be authenticated specifically corresponds to, namely the target fingerprint database.
By the method, the specific target fingerprint database is determined according to the pre-stored fingerprint information and the fingerprint content information of each preset fingerprint database, so that the fingerprint databases do not need to be opened in sequence for fingerprint authentication and matching.
Further, in order to quickly determine a target fingerprint database according to the fingerprint content information and the pre-stored fingerprint information, the step of determining the target fingerprint database from each of the pre-stored fingerprint databases according to the fingerprint content information and the pre-stored fingerprint information includes: comparing the fingerprint content information with prestored fingerprint information; and taking a preset fingerprint database in which the pre-stored fingerprint information consistent with the fingerprint content information is located as a target fingerprint database.
It should be understood that, after the fingerprint content information and the pre-stored fingerprint information are obtained, the fingerprint content information is compared with the pre-stored fingerprint information corresponding to each fingerprint to determine whether a consistent fingerprint exists, and after the pre-stored fingerprint information consistent with the fingerprint content information is determined, a corresponding pre-stored fingerprint library is determined after the pre-stored fingerprint information consistent with the fingerprint content information is determined, and then the pre-stored fingerprint library is used as a target fingerprint library.
By the method, the target fingerprint library which needs to be opened for fingerprint matching is quickly locked according to the fingerprint content information and the pre-stored fingerprint information.
Further, in order to enable the fingerprint matching to be continuously performed when the comparison between the configuration information to be authenticated and the pre-stored configuration file information fails, after the step of comparing the configuration information to be authenticated and the pre-stored configuration file information to obtain a first comparison result, the method further includes: and when the first comparison result is that the comparison fails, generating newly added configuration file information corresponding to the fingerprint to be authenticated, and storing the newly added configuration file information to the equipment file system.
It should be noted that, when the first comparison result is that the comparison fails, that is, there is no file corresponding to the configuration information to be authenticated in the pre-stored configuration file information, at this time, new configuration file information is generated and stored, that is, when there is no configuration file corresponding to the fingerprint to be authenticated in the device file system, the new configuration file information is automatically generated and stored, so that the device file system holds the device configuration file corresponding to the fingerprint to be authenticated.
By the method, the automatic generation is realized when the equipment file system has no corresponding configuration file, and meanwhile, the configuration file corresponding to the fingerprint does not need to be generated forcibly every time the equipment is started.
Further, the step of obtaining the pre-stored profile information stored in the device file system for obtaining the pre-stored profile information comprises: acquiring drive code information; and reading the chip id from the probe function in the drive code information through SPI communication to obtain the information of the pre-stored configuration file.
By the method, the information of the pre-stored configuration file is directly acquired from the code, so that the information of the pre-stored configuration file can be acquired without opening each preset fingerprint library.
The embodiment determines the to-be-authenticated configuration information and the fingerprint content information of the to-be-authenticated fingerprint according to the fingerprint verification information; calling a plurality of pre-stored preset fingerprint libraries; and matching each preset fingerprint database according to the configuration information to be authenticated and the fingerprint content information to determine a target fingerprint database. Through the method, the comparison and traversal of the configuration information to be authenticated and the fingerprint content information in the fingerprint verification information with the preset fingerprint libraries are realized, so that the matching can be performed without opening each preset fingerprint library in sequence, and only the traversal and the matching are performed before the opening, and the matching of opening the fingerprint libraries is performed after the target fingerprint library is determined.
