Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that any combination of the embodiments or technical features described below can be used to form a new embodiment without conflict.
As shown in fig. 1, a fingerprint authentication method according to a first embodiment of the present invention is applied to a fingerprint authentication device, and includes:
step S101: and selecting the first preset fingerprint as an identity certificate, and outputting a first authentication prompt.
In one embodiment, after the fingerprint authentication device acquires the user fingerprint authentication request, the first preset fingerprint is selected as the identity credential. The fingerprint authentication equipment can be a mobile phone, a computer, an attendance machine and the like. Before the user uses the fingerprint authentication device, a plurality of fingerprints are stored in the fingerprint authentication device in advance, for example, if the user of the fingerprint authentication device is a person, 5 fingers of the left hand are designated to be stored. If there are multiple users, the pre-stored fingerprints include finger fingerprints of different names of the multiple users.
The fingerprint authentication request can be made by pressing a fingerprint authentication request key on the fingerprint authentication device, or by a specific gesture. In one embodiment, the obtaining of the user fingerprint authentication request specifically includes: detecting a finger contacting or pressing the fingerprint authentication device. For example, whether the fingerprint authentication device is pressed by a finger may be detected by an infrared sensor.
The first preset fingerprint is one of the fingerprints pre-stored in the fingerprint device, and the first authentication prompt is a corresponding input prompt, such as "input left index finger fingerprint".
Step S102: the fingerprint of the finger to be verified is acquired.
Step S103: and judging whether the fingerprint of the finger to be verified is matched with the first preset fingerprint.
For example, the first authentication prompt is "left index finger fingerprint", and after the user inputs the fingerprint, the fingerprint authentication device matches the fingerprint input by the user with the pre-stored left index finger fingerprint to determine whether the fingerprint matches the pre-stored left index finger fingerprint.
Step S104: and if the fingerprint of the finger to be verified is matched with the first preset fingerprint, the authentication is passed.
After the authentication is passed, the fingerprint authentication device executes a preset instruction, for example, the mobile phone executes an unlocking or payment function, the fingerprint lock unlocks, the attendance machine signs in, and the like.
In the above embodiment, the first preset fingerprint is selected as the identity credential, the first authentication prompt is output, and after the user inputs the correct fingerprint according to the first authentication prompt, the authentication is passed, so that the security problem caused by the leakage of fingerprint information is avoided.
As shown in fig. 2, a fingerprint authentication method according to a second embodiment of the present invention is different from the first embodiment in that, after determining whether the fingerprint of the finger to be verified matches the first preset fingerprint, the method further includes:
step S201: and if the fingerprint of the finger to be verified is not matched with the first preset fingerprint, selecting a second preset fingerprint as an identity certificate, and outputting a second authentication prompt.
The second preset fingerprint is a fingerprint different from the first preset fingerprint and is one randomly selected by the fingerprint authentication device from the pre-stored fingerprints.
Step S202: and acquiring the fingerprint of the finger to be verified.
Step S203: and judging whether the fingerprint of the finger to be verified is matched with the second preset fingerprint.
Step S204: and if the fingerprint of the finger to be verified is matched with the second preset fingerprint, the authentication is passed.
In one embodiment, if the fingerprint of the finger to be verified matches the second preset fingerprint, the authentication is passed, the fingerprint authentication device executes the corresponding instruction, and if the fingerprint of the finger to be verified does not match the second preset fingerprint, the next fingerprint is randomly selected as the identity certificate, and the first authentication prompt is output again to perform fingerprint authentication. And if the authentication times set by the fingerprint authentication equipment are reached, locking the fingerprint authentication equipment.
In one embodiment, if the current fingerprint authentication fails, the probability of collecting the fingerprint with failed authentication is increased in the next fingerprint authentication process. For example, if the fingerprint authentication method is random 5 fingers of both hands, if the right middle finger fails to match in one fingerprint matching process, the probability of acquiring the right middle finger fingerprint is increased in the remaining fingerprint matching processes. Further, if the current fingerprint authentication fails and the similarity between the fingerprint of the finger to be authenticated and the preset fingerprint is judged to be smaller than the preset threshold value, the acquisition probability of the fingerprint failing authentication is increased.
In the above embodiment, when the first preset fingerprint passes the non-authentication as the identity credential, the second preset fingerprint is used as the identity credential to authenticate the fingerprint of the finger to be verified again, so that the security of the fingerprint authentication device is improved.
As shown in fig. 3, a fingerprint authentication method according to a third embodiment of the present invention is different from the first embodiment in that the method further includes:
step S301: and acquiring the retry number of fingerprint authentication.
In one embodiment, after acquiring the fingerprint authentication request of the user, the number of fingerprint authentication retries is accumulated, for example, if the user has failed fingerprint authentication twice consecutively, the number of fingerprint authentication retries is 2.
Step S302: and judging whether the retry times of the fingerprint authentication reach preset times or not.
The preset times are less than or equal to the number of user fingerprints preset in the fingerprint authentication equipment. For example, the number of the preset user fingerprints is 5, and the preset number of times is 3, so that even if one fingerprint is leaked, the probability of passing the authentication by using the leaked fingerprint is lower than 50%, and the safety of the fingerprint authentication device is improved.
Step S303: and if the retry times of the fingerprint authentication reach preset times, rejecting the fingerprint authentication request.
For example, the preset number of times is 5, and if the user fails to authenticate for 5 consecutive times, the fingerprint authentication request of the user is rejected, and the fingerprint authentication device is locked. If the user fingerprint authentication is successful, the retry number is reset to the first preset number, for example, to the original 5 times.
In the above embodiment, the number of retries of fingerprint authentication is limited, thereby ensuring the security of the fingerprint authentication device.
As shown in fig. 4, a fingerprint authentication method according to a fourth embodiment of the present invention is different from the first embodiment in that the method further includes:
step S401: acquiring a fingerprint authentication risk value;
in one embodiment, the fingerprint authentication risk value is incremented after authentication fails. Specifically, the fingerprint authentication risk value may be increased according to the similarity between the fingerprint of the finger to be verified and the preset fingerprint, and the lower the similarity is, the more the increased risk value is.
Step S402: and judging whether the fingerprint authentication risk value reaches a preset risk value, if so, passing the fingerprint authentication only if the fingerprints of more than 2 fingers are successfully matched.
In the above embodiment, the risk value of the fingerprint authentication is evaluated, and the security of the fingerprint authentication device is further improved.
As shown in fig. 5, the fingerprint authentication device provided by the embodiment of the present invention includes a processor 11 and a memory 12, where the memory 12 stores a computer readable program, the computer readable program is configured to be executed by the processor 11, and the computer readable program implements the method described above when executed by the processor 11.

From the above description of the embodiments, it is clear to those skilled in the art that the present invention can be implemented by software plus necessary general hardware platform. Based on this understanding, the technical solutions of the present invention may be embodied in the form of software products, which essentially or partially contribute to the prior art. The invention also relates to a computer-readable storage medium, such as ROM/RAM, magnetic disk, optical disk, etc., on which a computer program is stored which, when executed by a processor, implements the above-described method.
