Abstract

The invention discloses an identity authentication system and method based on infrared communication, and relates to the field of infrared dot matrix multi-signal processing methods and identity authentication. The problem that an existing infrared authentication mode is low in authentication efficiency is solved. According to the invention, each user side is used for generating a character string carrying a timestamp and converting the character string into an infrared signal; a receiving end is used for converting each received infrared signal into a digital signal, preliminarily identifying each digital signal through first authentication information in a first database, and sending the digital signal which is preliminarily identified to be qualified to the security authentication server; and a security authentication server decrypts the received digital signals which are preliminarily affirmed to be qualified, after the timestamps in the decrypted digital signals are successfully authenticated, the digital signals after the timestamps are successfully authenticated are respectively matched with corresponding second authentication information in a second database, and the matching result is used as an authentication result to be sent to a corresponding user side. The system is mainly used for identity authentication.

Description

technical field [0001] The invention relates to an infrared lattice multi-signal processing method and the field of identity authentication. Background technique [0002] Current mainstream identity authentication technologies include NFC authentication, RFID authentication, network authentication, magnetic card authentication, etc.; [0003] NFC authentication and magnetic card authentication are only suitable for short-distance identity authentication due to the limitation of communication distance. In densely populated environments, congestion is prone to occur, resulting in low efficiency; [0004] Due to the particularity of its physical medium, the RFID authentication method is costly and difficult to provide high-intensity protection of the information in the medium, which is prone to personal privacy leakage; [0005] Due to the inherent virtuality and anonymity of the Internet, network authentication cannot accurately determine the identity and location of the auth...
