A Two-Factor Authentication Method Based on Temperament Format Information

Abstract

The invention discloses a tonality format information based double-factor identity authentication method. The authentication method includes that an audio collector performs data sampling on tonality information according to a twelve-tone equal temperament format to generate twelve-tone equal temperament information, an audio identifying device performs tonality identification on the twelve-tone equal temperament information on the basis of a tonality identification algorithm of an H-K algorithm to generate binary coding information, an information encryption device uses an SM3 encryption algorithm to encrypt the binary coding information on the basis of a time factor to generate a number format challenge code, a user inputs the number format challenge code into a hardware token, the hardware token performs encryption conversion on the number format challenge code through the SM3 algorithm on the basis of the time factor to obtain a dynamic password, and the user inputs the dynamic password into an identity authentication server for user's identity authentication. According to the tonality format information based double-factor identity authentication method, on the basis of absoluteness and peculiarity of the tonality formation information, the challenge code in the two-factor identity authentication is generated, so that the challenge code is not prone to be affected by single parameters such as time.

Description

technical field [0001] The invention relates to the field of electronic authentication, in particular to a two-factor identity authentication method based on rhythm format information. Background technique [0002] With the development of e-commerce and the advancement of mobile terminal technology, people use mobile terminals more and more frequently for online consumption, and electronic payment has become one of the main means of payment for people. While electronic payment brings convenience to consumers, it also raises new issues for payment security. How to improve the reliability of electronic authentication is a technical problem that many electronic security technology development companies urgently need to solve. The use of dynamic passwords for user identity verification is a commonly used authentication method in electronic payment. There are time synchronization, event synchronization and challenge-response modes for the use of dynamic passwords. The dynamic p...
