Dynamic authentication method and system based on mobile terminal

Abstract

The invention discloses a dynamic authentication method and system based on a mobile terminal. The dynamic authentication method based on the mobile terminal comprises the steps of: S100, acquiring to-be-authenticated reference information of a subordinate mobile terminal in a database in a preset time limit, and storing the database in a server; S200, carrying out safety detection on the to-be-authenticated reference information of the subordinate mobile terminal in the database; S300, according to result information obtained after carrying out safety detection on the to-be-authenticated reference information in the step S200, setting a corresponding dynamic authentication strategy; and S400, according to the dynamic authentication strategy set in the step S300, carrying out corresponding authentication when a user logs in. In the invention, according to detection on a safety state of the mobile terminal, when the safety state is good, a low-level authentication strategy is used, and when the safety state is poor, authentication strength is automatically strengthened; and user experience is more intelligent, and authentication strength is more reasonable and safer.

Description

technical field [0001] The invention relates to the field of network communication monitoring, in particular to a mobile terminal-based dynamic authentication method and system. Background technique [0002] Identity authentication is part of the identity management system, which mainly judges the authenticity of the identity of the entity user based on the current information. At present, most identity authentication systems are based on user names and passwords; some systems with high requirements for information security (such as financial services, etc.), all assist equipment or user questions and answers to strengthen the security level. [0003] Authentication plays a vital role in a security system, and authentication technology determines the security level of the system. At present, most information systems adopt the method of user name and password, which has low security strength. In the password-based authentication method, the password does not change with time...

AI Technical Summary

Problems solved by technology

Therefore, the one-time password authentication method is prevalent, but the authentication items of this common authentication method are always the same each time. This method is also used when the security requirements of the business are not very high, which will increase the user's operations. affect user experience
