Identity authentication method and its identity authentication system

Abstract

When system receives authentication request, random code generation device generates a random cipher. With random cipher and presetting fixed cipher for id authentication being received, digital processing device calculates and generates input code based on preset algorithm. The digital processing device obtains random cipher and fixed cipher of id authentication from the said input code based on inverse computation of preset algorithm so as to carry out id authentication, or id authentication is carried out based on input code directly. In each authentication, the invention uses different cipher. Thus, even input cipher is revealed or stolen in this time, encroachment is not possible to be made for obligee. The invention raises safety. Fixed cipher is not necessary to be modified frequently. Different transmission paths combined in the invention is also lowered probability of data to be stolen.

Description

【Technical field】: [0001] The invention relates to an identity authentication system and method for identity authentication. 【Background technique】: [0002] Existing password-based identity authentication systems, in practical applications, such as entering email systems, financial systems, passing through access control systems, opening safes, etc., generally need to enter a fixed password set by the customer for identity authentication. Since the user directly enters the fixed password for identity authentication and then the identity authentication system performs effective identity authentication, in many cases, the user's input is easily illegally recorded and the password is leaked. For example, the identification system based on network applications is often intercepted by malicious programs by recording user input information, and the input of passwords in public places such as banks is easily illegally recorded, resulting in user password leakage and other hidden d...

Since the user directly enters the fixed password for identity authentication and then the identity authentication system performs effective identity authentication, in many cases, the user's input is easily illegally recorded and the password is leaked

For example, the identity recognition system based on network applications is often intercepted by malicious programs by recording user input information, and the input of passwords in public places such as banks is easily illegally recorded, resulting in user password leakage and other hidden dangers.

In this way, the user is forced to carefully protect the input process from being recorded while frequently changing the password, which brings great security risks and inconvenience to the user.

When using the network, whether it is online banking, online games, sending and receiving emails, etc., identity authentication is required first. At this time, the information input from the keyboard is easily recorded by the Trojan horse program in the network. name, password, etc., if illegally obtained, it is likely to cause infringement to the right holder and cause him to suffer losses
