Identity authentication method, device and system

Abstract

The invention relates to an identity authentication method, device and system. The method comprises the following steps that: a client sends a request for authenticating an account number to a server; the server judges whether the client has a large file; if the client has the large file, the server judges whether the account number is bound with the large file; if the account number is bound with the large file, the identity authentication is directly carried out; if the account number is not bound with the large file, the account number is bound with the large file and then the identity authentication is carried out; and if the client does not have the large file, the client is initialized to generate the large file, then the account number is bound with the large file, and finally, the identity authentication is carried out. According to the method disclosed by the invention, only by generating the large file at the client at one time and binding the account number, the authentication step can be automatically carried out by the system if a user uses the account number to log in from the same client in future; no hardware cost is generated; the whole authentication process is unnecessary to be interacted with the user; the method is very convenient; and the safety protection to the account number of the user is realized.

Description

technical field [0001] The present invention relates to the technical field of information security authentication, in particular to an identity authentication method, device and system. Background technique [0002] Authentication technology is an important aspect of information security theory and technology. It mainly includes information authentication and identity authentication. Information authentication is used to ensure the integrity and anti-repudiation of information, and identity authentication is used to identify user identities. Restrict unauthorized users from accessing resources. Among them, identity authentication is an important aspect of security technology. When users access encrypted content, they must prove their identities through some form of identity authentication mechanism. Access to encrypted content, identity authentication is the first checkpoint in the security system. Before accessing the security system, the user first passes through the ide...

Problems solved by technology

[0010] However, due to the certain hardware cost and high security cost of two-factor authentication, it cannot cover all users, such as palmprint recognizers, dynamic password cards, etc.; moreover, user interaction is required, and a certain user experience needs to be sacrificed, such as dynamic password cards. The user manually enters the dynamic password, and the iris recognition requires the user to align the eyes with the recognizer, which cannot be popularized among all users and cannot fundamentally solve the problem of account theft
