Problems solved by technology

In order to further improve security, a Chinese patent application with the publication number CN105354464A and titled "Method and Device for Identifying User Identity Based on Fingerprint Information" proposes a new scheme. Even if multiple fingerprints are copied through fingerprints, it cannot be successfully decrypted without knowing the sequence of multiple fingerprints, and the security is relatively improved
[0003] However, based on technical limitations and the particularity of fingerprints, fingerprint recognition also has a certain failure rate, especially in the case of finger injuries, the failure rate will be higher. The success rate k of a fingerprint recognition may be higher, but n The success rate of a fingerprint sequence composed of five fingerprints will be the nth power of k. The more fingerprints, the lower the success rate. If the identification cannot be successfully identified, it may bring significant losses or influence to the user.
For example, if the fingerprint sequence is used as a bank password, once the fingerprint sequence cannot be successfully identified, financial transactions will not be possible, which may cause major economic losses to the user

Embodiment 1

[0020] See figure 1 The identity authentication method based on the fingerprint password provided in this embodiment, including the steps:

[0021] Get the fingerprint sequence entered by the user. The fingerprint sequence includes a plurality of fingerprints, and a plurality of fingerprints are arranged in a particular order. When the user enters the fingerprint sequence, the fingerprint of the same location cannot be reused, for example, it cannot be repeatedly entered into the finger of the finger because the finger of a finger is not entered, avoiding the judgment affecting whether the fingerprint is matched.

[0022] The fingerprint of each position in the fingerprint sequence is compared with the corresponding position of the corresponding position in the preformed standard fingerprint sequence, and the number of fingerprint matches is statistically.

[0023] In this step, if a certain position in the acquired fingerprint sequence is not collected to the fingerprint, or the ...

Embodiment 2

[0030] See figure 2 The identity authentication method based on the fingerprint password provided in this embodiment, including the steps:

[0031] Get the fingerprint sequence entered by the user.

[0032] The fingerprint of each position in the fingerprint sequence is compared with the corresponding position of the corresponding position in the preformed standard fingerprint sequence, and the number of fingerprint matches is statistically.

[0033] It is determined whether the fingerprint match rate is greater than or equal to the set threshold. If so, the identity authentication is successful, and if the fingerprint matching rate is less than the set threshold, it is further determined whether the fingerprint of the standard fingerprint is the same fingerprint, if it is the identity Certification is successful, otherwise identity authentication failed.

[0034] For example, assuming, the threshold is 80%, the pre-stored standard fingerprint sequence is 3, 4, 6, 2, 1, 2, 5. If t...

Abstract

The invention relates to an identity authentication method and device based on a fingerprint password. The method comprises the steps of: obtaining a fingerprint sequence entered by a user; Compare and count the number of fingerprint matches. If the fingerprint matching rate is greater than or equal to the set threshold, the identity authentication is successful, otherwise the identity authentication fails. Identity authentication through the method and device of the present invention can not only ensure safety and reliability, but also avoid failure of fingerprint identification due to finger injury or other reasons, thereby affecting the normal use of fingerprint passwords.

Description

Technical field [0001] The present invention relates to the field of identification techniques, and in particular, to an identity authentication method and apparatus based on a fingerprint password. Background technique [0002] At present, everyone will have a variety of passwords, such as bank passwords, website passwords, WeChat passwords, and passwords are easier to forget, so many people use a password. However, once the password is stealing, it will cause all information disclosure of this password, there is a large security hazard. Fingerprint is a unique biometric feature of everyone, so it can improve security as a password. In order to further improve the safety, the public name is CN105354464A, which is "a method and apparatus based on fingerprint information identification user identity." The password is composed of multiple fingerprints, and multiple fingerprints according to specific The order is arranged, even if multiple fingerprints are copied by the model, it is...
