In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
Referring to fig. 1, fig. 1 is a schematic diagram of a fingerprint identification method provided by an embodiment of the present invention, where the fingerprint identification method is used for an electronic device, and the fingerprint identification infringement method includes:
step S11: and acquiring a fingerprint identification instruction of the first application program at the current moment.
When the electronic equipment runs the first application program, the first application program needs to be subjected to fingerprint identification, and after the identity condition is met through the fingerprint identification, a preset function is executed. The user can input the fingerprint identification command through a touch panel or a mechanical key.
Step S12: and executing the fingerprint identification instruction, and collecting the current fingerprint information of the user.
The electronic equipment can acquire the current fingerprint information of the user through the built-in fingerprint sensor.
Step S13: and judging whether the standard fingerprint information acquired at the initial moment, the n pieces of fingerprint information stored recently and the current fingerprint information meet a first condition.
The n pieces of fingerprint information which are stored recently are n pieces of fingerprint information which are stored through fingerprint identification authentication at n other moments between the initial moment and the current moment, and n is a positive integer. n may be set according to requirements, for example, n may be set to 5, 4, 3, or the like.
Step S14: if so, a preset function is executed.
If not, the fingerprint identification process is stopped, and the next fingerprint identification is waited.
The change rule of the fingerprint of the user in the abrasion process can be judged according to the standard fingerprint information acquired at the initial moment and the n pieces of recently stored fingerprint information, namely, the finger is abraded more seriously along with the time, the fingerprint information of the user is gradually changed due to abrasion, and the fault tolerance rate of the fingerprint information of the user acquired in the two adjacent fingerprint detection processes is gradually increased along with the time.
On the basis of a fingerprint identification mode according to the current fingerprint information and the standard fingerprint information at the initial moment, the fingerprint identification method further performs fingerprint identification according to the change rule of the user fingerprint in the abrasion process, can avoid the problem that the identity of the user cannot be accurately identified due to the abrasion of the user fingerprint, and is convenient to use.
Fig. 2 shows a method for determining whether the standard fingerprint information acquired at the initial time, the most recently stored n pieces of fingerprint information, and the current fingerprint information satisfy a first condition, where fig. 2 is a schematic flow diagram of the method for determining whether the first condition is satisfied according to the embodiment of the present invention, where the method includes:
step S21: and comparing the current fingerprint information with the standard fingerprint information and the n pieces of recently stored fingerprint information in sequence respectively.
Step S22: and acquiring n +1 fault tolerance rates based on the n +1 comparison results.
Setting the standard fingerprint information collected at the initial moment as Z0The fingerprint information collected at the current moment is ZXAccording to the above description, n pieces of fingerprint information are stored between the initial time and the current time, where the n pieces of fingerprint information are the n pieces of fingerprint information stored recently, and the n pieces of fingerprint information are sequentially set to Z from first to last in time order1And Zn。

As described above, finger wear is a gradual process over time, and the more severe the wear, the greater the fault tolerance of the fingerprint information of the user acquired in two adjacent fingerprint detection processes.
Specifically, the determining whether the first condition is satisfied based on the n +1 change rules of the fault tolerance includes: and if the fault tolerance rate does not exceed a set threshold value and the fault tolerance rate is gradually reduced along with the time, the first condition is met, and if the fault tolerance rate does not exceed the set threshold value, the first condition is not met. The fault tolerance of each comparison result can be set to correspond to the same threshold, or each comparison result is respectively set to a threshold.
The fingerprint identification method of the embodiment of the invention also comprises the following steps: and setting the size of the threshold according to the security level of the first application program. The user can set different security levels according to different applications. Specifically, the secure operation of the network payment application is related to the property security of the user, and the security level of the network payment application can be set to be higher than that of other applications, for example, the security level of shopping payment is set to be higher than that of unlocking a mobile phone screen. The higher the security level of the application program, the smaller the threshold corresponding to the fault tolerance rate in the fingerprint identification process.
If the first condition is satisfied, the fingerprint identification method according to the embodiment of the present invention further includes: and storing the current fingerprint information. Furthermore, in order to reduce the amount of stored information, after storing the current fingerprint information, the method further includes deleting the first fingerprint information of the n pieces of latest stored fingerprint information, so that only n pieces of latest fingerprint information passing through fingerprint identification authentication need to be stored all the time, so as to facilitate the execution of the fingerprint identification method according to the embodiment of the present invention.
The following illustrates the implementation of the fingerprint identification method according to the embodiment of the present invention.
And after the standard fingerprint information is collected at the initial moment, storing the standard fingerprint information for fingerprint identification. It should be noted that, after the standard fingerprint information is stored, when fingerprint identification is performed for the first time, only under the condition that the matching rate of the standard fingerprint information is greater than 99.99%, that is, under the condition of extremely high matching rate, the fingerprint information passing through fingerprint authentication is stored for the identification basis of the next fingerprint authentication.
For example, the threshold corresponding to the fingerprint recognition of the payment application program is set to be 20%, and the threshold corresponding to the fingerprint recognition of the non-payment application program is set to be 5%; setting m records passing through fingerprint authentication between the initial time and the current time, wherein m is a positive integer not less than n. When the fingerprint identification method according to the embodiment of the present invention is executed, if n is set to 5, that is, the latest 5 pieces of fingerprint information are selected from the m pieces of fingerprint information corresponding to m times of fingerprint authentication, and the 5 pieces of fingerprint information, the standard fingerprint information, and the current fingerprint information are used for fingerprint identification.
As shown in table 1 below, when the current fingerprint information corresponding to a non-payment application program corresponds to Z0-Z5When the fault tolerance after comparison is 20%, 15%, 10%, 5%, 1% and 0.1% in sequence, the setting is satisfied: the fault tolerance rate does not exceed the threshold value and is gradually reduced along with the time, so that a first condition is met, and a preset function can be executed through the application program through fingerprint authentication; when the current fingerprint information corresponding to a certain payment application program is matched with Z0-Z5When the fault tolerance after comparison is 5%, 4%, 3%, 2%, 1% and 0.1% in sequence, the setting is satisfied: the fault tolerance rate does not exceed the threshold value and gradually decreases with the lapse of time, so that the first condition is satisfied, and the preset function can be executed through the application program through the fingerprint authentication.

In the fingerprint identification method of the embodiment of the invention, the matching fault-tolerant rate of the current fingerprint information and the last stored fingerprint information is in a certain range, the fingerprint identification authentication can still be successfully completed, and the current fingerprint information is stored as the identification basis of the next fingerprint identification. Therefore, by adopting the fingerprint identification method provided by the embodiment of the invention, the fingerprint information used for fingerprint comparison can be continuously updated and stored in the fingerprint identification process, the acquisition process of marking the fingerprint information is not required to be additionally added, the fingerprint database can be continuously updated in the process of fingerprint abrasion of a user, and the problem that the identity of the user cannot be accurately identified due to fingerprint abrasion of the user is avoided.
In the fingerprint identification method of the embodiment of the invention, different fault tolerance rates can be set for application programs, such as account login of a mobile phone, account login of a computer, reading of original information and lookup of recently read information, and the threshold corresponding to the fault tolerance rate can be properly improved to ensure information safety. For the application programs needing to be paid through fingerprint authentication, the fault tolerance rate of each comparison can be set to correspond to a threshold, and the corresponding fault tolerance rate security level is improved by one level compared with other non-payment application programs, namely the threshold is smaller.
When the fingerprint identification method is adopted, a user can set the fingerprint identification rate of each fingerprint identification according to the security level of the application program, for example, the application programs such as internet bank and internet purchase payment can set the fingerprint identification rate of each fingerprint identification to be not less than 99.99%, namely, the threshold corresponding to the fault tolerance rate of each comparison is not less than 0.01%, and all the fault tolerance rates are required to be gradually reduced along with the time, while other application programs with common security levels such as mobile phone unlocking and the like set the fingerprint identification rate to be lower, for example, 80%, namely, the threshold corresponding to the fault tolerance rate of each comparison is not more than 20%, and all the fault tolerance rates are required to be gradually reduced along with the time.
