Intelligent security chip signature information transmission method and system based on 2-dimensional bar code

Abstract

The invention relates to an intelligent security chip signature information transmission method and system based on a 2-dimensional bar code. The 2-dimensional bar code is generated by the following steps: an intelligent security chip is inserted into a terminal device; the intelligent security chip is used to put a signature on the original data and thus signature value information is obtained; and the terminal device assemblies the original data, the signature value information and a message verification code to generate a 2-dimensional bar code, and displays the 2-dimensional bar code. Scanning authentication of the 2-dimensional bar code comprises the following steps: an application scans the 2-dimensional bar code, parses the data of the 2-dimensional bar code so as to obtain the to-be-authenticated data, and then sends the to-be-authenticated data to an application background; an authentication center verifies the to-be-authenticated data, and sends a verification result back to the application through the application background. With application of the intelligence security chip signature information transmission method and system based on a 2-dimensional bar code, in an intelligent card identity authentication application system, the problem of poor data communication between an intelligent card and a background system due to unavailable card reading devices is solved, so that comparative transmission of the signature information of the intelligent card is fulfilled without using a particular intelligent card reading device.

Description

technical field [0001] The present invention relates to the technical field of authentication, in particular to the technical field of two-dimensional code authentication, in particular to a method and system for transmitting signature information of an intelligent security chip based on a two-dimensional code. Background technique [0002] With the widespread use of mobile terminal equipment, the security of mobile terminal equipment has attracted more and more attention. When people use mobile terminal devices, they need to log in to websites such as Taobao, Weibo, Community, and Renren. Especially when logging in to a shopping network, the user needs to input a user name and a password. During the authentication process, the user only enters the user name and password, and passwords are used too frequently in people's daily life, so people need to remember many passwords, because if a single password is used, if one platform is compromised, all platforms will face disaste...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art, provide a method and system for transmitting signature information of intelligent security chips based on two-dimensional codes, and solve the problems caused by the unpopularity of card reading equipment in the existing smart card identity authentication application system. It is difficult to communicate data between the smart card and the background system, and realize the compatible transmission of smart card signature information without using a specific smart card reading device
