Two-dimensional code identification method based on digital signatures and timestamps

Abstract

The invention discloses a two-dimensional code identification method based on digital signatures and timestamps. The two-dimensional code identification method comprises the steps of performing the digital signatures and stamping the timestamps. Because the timestamps are adopted in electronic identification of the two-dimensional code identification method disclosed by the invention, the signature time can be fixed; the integrity and the authenticity of a time stamp are ensured through the digital signatures; the backdating behaviour can be effectively prevented; the security protection to electronic identity information is enhanced; strong evidences can also be provided for related disputes; and the two-dimensional code identification method disclosed by the invention can be applicable to occasions, such as meeting signatures, entrance guards and payments.

Description

technical field [0001] The invention relates to the technical field of electronic identification, in particular to a two-dimensional code identification method based on digital signatures and time stamps. Background technique [0002] At present, there are many researches on the identification and authentication of QR codes in the market. Today, with the highly developed Internet, this technology has become a popular research field for many researchers due to its wide range of applications. The current research mainly focuses on the identification of users by using digital signatures alone. [0003] The publication number CN104113416A published on June 26, 2014 discloses a two-dimensional code verification method and system based on an electronic signature. Sign, and divide the electronic signature into the first and second signature segments and send them to the two-dimensional code authenticator; the two-dimensional code authenticator authenticates the two-dimensional cod...

AI Technical Summary

Problems solved by technology

[0004] Although the above method can guarantee the security of the QR code to a certain extent, its implementation method is cumbersome and cannot reflect the characteristics of the electronic signature in terms of time, so there are great limitations in actual use.

In addition to the above methods, other current technologies often simply use digital signatures for user identity authentication, ignoring the special requirements for time in the identity authentication process
