A traceability-based user information authentication method

Abstract

The invention provides a user information authentication method based on traceability. The user information authentication method comprises the following steps of authenticating user identity; establishing a behavior authentication set; carrying out creditability authentication on the user behavior based on the D-S evidence theory; and tracking and authenticating the user identity. The user information authentication method in the technical scheme is used for solving the identity authentication problem of network users in the internet, the method can be used for realizing dual authentication of the user identity and the user behavior, thereby not only effectively avoiding illegal users accessing the network, but also regulating the network behaviors of the users, and thus the security of the internet is greatly improved.

Description

technical field [0001] The invention relates to an authentication method, in particular to a user information authentication method based on traceability. Background technique [0002] With the continuous popularization and deepening of network information system applications, more and more attention has been paid to information security issues. In order to ensure the security of information systems, terminal security protection has become an urgent problem to be solved. [0003] As the first gate of computer and network system security, end-user authentication technology is an important technical means to confirm the identity of the operator. At present, commonly used security protection measures include issuing digital certificates to users, USB user keys, biometric features (fingerprint, iris) and other auxiliary security means to verify the authenticity of user identities and ensure the safety of users in Internet activities. [0004] In recent years, the development of...

Problems solved by technology

Specifically, the disadvantages of the password mechanism are: the password is transmitted to the verification server in plain text, which is easy to be intercepted during the period, and the cost of password maintenance is relatively high; however, to ensure security, the password should be changed frequently, and to avoid dictionary attacks on the password , the password should have a certain length and is difficult to remember; the password is easy to be peeped by others when entering

The disadvantages of biometric technology are: the precise experimental equipment required for biometric recognition is usually more expensive, and because many biological characteristics of people will change; therefore, this method has low stability and high recognition failure rate
