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...
