Problems solved by technology

[0002] The application of fingerprint encryption and decryption is becoming more and more extensive. So far, the method of fingerprint encryption with a single fingerprint is usually used, or the method of fingerprint encryption with multiple identifications for a single fingerprint; but these methods have certain risks. The features can be copied. When the fingerprint information is stolen, the single fingerprint encryption method has great security risks. Therefore, improving the security level of fingerprint passwords has become an urgent problem to be solved.

Abstract

The invention discloses a fingerprint encryption and decryption method and a fingerprint encryption and decryption system. The fingerprint encryption method includes obtaining at least two authorized fingerprint information; processing the at least two authorized fingerprint information and input sequence information to obtain a fingerprint password; setting the fingerprint password as a preset fingerprint password. In the present invention, the fingerprint password is set through the authorized fingerprint information. The fingerprint password not only includes the authorized fingerprint information, but also includes the input sequence information of the authorized fingerprint information, which can increase the difficulty of decrypting the fingerprint password and improve the security level of the fingerprint password.

Description

technical field [0001] The invention relates to the technical field of improving password security level, in particular to a fingerprint encryption and decryption method and a fingerprint encryption and decryption system. Background technique [0002] The application of fingerprint encryption and decryption is more and more extensive. So far, the method of fingerprint encryption with a single fingerprint is usually used, or the method of fingerprint encryption with multiple identifications for a single fingerprint; but these methods have certain risks. Features can be copied. When the fingerprint information is stolen, the method of single fingerprint encryption has great security risks. Therefore, improving the security level of fingerprint passwords has become a problem that needs to be solved urgently. Contents of the invention [0003] In view of this, the present invention provides a fingerprint encryption and decryption method and a fingerprint encryption and decrypt...
