Fingerprint encryption-based identity authentication system and implementation method thereof

Abstract

The invention discloses a fingerprint encryption-based identity authentication system. The system comprises a user interface, a key interface, a database, a password processing unit, a fingerprint processing unit, a conversion processing unit, a decryption processing unit and an encryption processing unit, wherein the user interface is connected with the password processing unit and the fingerprint processing unit respectively; the password processing unit, the fingerprint processing unit, the decryption processing unit and the encryption processing unit are connected with the conversion processing unit respectively; and the decryption processing unit and the encryption processing unit are connected with the database and the key interface respectively. The invention also discloses an implementation method of the fingerprint encryption-based identity authentication system, which comprises the steps of encryption and decryption. The system and the method have the advantages that: a biological characteristic password can be allowed to be cancelled and can be reset for unlimited times, the safety is high, cross-comparison bugs are prevented, and the like.

Description

technical field [0001] The invention relates to technical fields such as biological signal encryption, in particular to an identity authentication system based on fingerprint encryption and an implementation method thereof. Background technique [0002] In recent years, due to the emergence and increasing popularity of identity authentication systems, we can carry out e-commerce through user authentication, telephone payment, etc. without leaving home, and participate in efficient modern life such as remote information management and online shopping. Individuals and enterprises have become accustomed to transmitting sensitive data and business secrets through the security authentication system for network transmission. However, these traditional encryption systems also have shortcomings such as inconvenient use and difficult memory. Typical encryption keys are random and long enough, and it is difficult for people to memorize these lengthy random character strings, so such ...

AI Technical Summary

Problems solved by technology

So both the original template and the key are compromised

[0017] (2) The uniqueness of the biometric template makes the template irrevocable

As we all know, passwords can be changed at any time. Once the original password encounters a security problem, the problem can be solved by revoking the original password and entering a new password. However, for the same fingerprint, the characteristic information is fixed and cannot be changed. Once a security problem occurs This fingerprint cannot be used again
