An identity authentication system and authentication method based on portrait and intelligent server

Abstract

The invention relates to an identity authentication system based on a portrait and an intelligent server and an authentication method. The identity authentication system comprises a client end and an intelligent server. The client end directly interacts with a user and communicates with the intelligent server via network connection. The client end has three effects that firstly a user can choose the portrait as a command image when setting a command; secondly, challenge image sets are displayed so that the user can identify the command image by selecting the challenge image sets during the identity authentication process of the user; and thirdly, authentication results can be given out after the identity of the user is authenticated. The intelligent server is used for establishing and maintaining data base of the command images, supplementing the command images uploaded by the user into the data base, and searching and implementing images from the Internet to the data base. The intelligent server can help the user to set the command images, searches equivalent images from the data base and matches interference images for the command images, and sends the equivalent images and the interference images to the client end. According to the invention, safety and user friendliness of the system are improved.

Description

technical field [0001] The invention belongs to the field of information security, and in particular relates to an identity authentication system and authentication method based on a portrait and an intelligent server. Background technique [0002] Graphical password authentication is a kind of knowledge-based authentication. It does not require users to memorize long and complex string passwords. Users can pass identity authentication as long as they recognize a specific image (image and graphic have the same meaning in this paper, and no distinction is made). The disadvantage is that the images are usually abstract and difficult for users to remember. If the system uses a portrait (portrait in this paper refers to the image in which the face of a single character is the main body in the entire image) as the password image, when the user is familiar with the character corresponding to the portrait, the user can easily identify the password character And identify the passwo...

Problems solved by technology

[0003] The existing authentication system using portraits as passwords overcomes the shortcomings of abstract images that are not easy to remember, and the system can automatically match the corresponding interference images for password images; however, since the interference images in the system are taken from a fixed gallery, Snoopers can often pick out passwords by exclusion, so their security isn't great

There are also some authentication systems, the interference image can be changed, but the password image must come from a person who is not well-known and usually only famous in a small range, which is not conducive to the construction and maintenance of the system itself, but also reduces its user-friendliness
