Identity authentication method, equipment and system

Abstract

The invention discloses an identity authentication method, equipment and system. The identity authentication method comprises the steps: user characteristic analysis equipment receives a user characteristic query request which is sent from a server when the server determines that the user name and the password of a login user are matched with the reserved user name and password of the login user, wherein the user characteristic query request carries the user behavior characteristic information of the login user; and the user characteristic analysis equipment matches the carried user behavior characteristic information of the login user with the reserved user behavior characteristic information of the login user so as to return an authentication response message to the server according to the matching degree between the carried user behavior characteristic information of the login user and the reserved user behavior characteristic information of the login user. In other words, for the scheme of the identity authentication method, equipment and system, based on traditional user-name+password authentication, the user behavior characteristic information is introduced to perform further authentication on the user identity, so that the dilemma of memorizing complicated passwords for the user is avoided; the difficulty in managing the passwords by the user is reduced; and the account number safety is improved. Besides, relative to the traditional authentication mode which requires hardware authentication equipment and the like, the scheme of the identity authentication method, equipment and system also has the advantage of reducing the identity authentication cost.

Description

technical field [0001] The present invention relates to the technical field of information security, in particular to an identity authentication method, device and system. Background technique [0002] At present, user identity authentication methods can be mainly divided into three categories. The first type is based on user name + password. way; the third category is based on the user's innate biological characteristics, such as fingerprints, iris, voice, facial features, and other identity authentication methods. [0003] Among the above three types of identity authentication methods, the identity authentication method of the first type "username + password" has become the most widely used identity authentication method because it is easy to use and easy to remember. security risks. A study shows that 1% of user passwords can be guessed within 4 times, and there are many common passwords, such as 123456, 12345678, password, qwerty, etc. Even if users are lucky enough to...
