A password generation system and method based on slice graphics

Abstract

The present invention relates to a system and method for generating passwords based on sliced ​​graphics. The system includes: a graphics setting module for selecting graphics and their quantity for password input; a graphics slicing module for setting the slicing mode and Slicing quantity, and slice each graphic according to the slicing mode and the slicing quantity; input password collection module, for collecting the user's input password information, said input password information refers to the graphic blocks selected by the user and the order of the selected graphic blocks; Password generating module, for converting the graphic blocks in the input password information into encoding conversion based on the HASH algorithm to obtain the text strings of the corresponding graphic blocks, and storing each text string as a password in the order of selecting graphic blocks in the input password information; password database. Compared with the prior art, the present invention has the advantages of simple and convenient operation, large password space, easy memory, small storage space, anti-shoulder peeping and the like.

Description

technical field [0001] The present invention relates to the field of information security, in particular to a password generation system and method based on slice graphics. Background technique [0002] In recent years, researchers at home and abroad have continuously proposed many new graphic cipher schemes. According to the memory form and input method of passwords, the existing graphic password schemes can be roughly divided into three categories: graphic passwords based on image recognition (recognition-based), graphic passwords based on recall (recall-based) and clue-based passwords. Graphical cipher for recall (cued-recall). [0003] (1) Graphic password scheme based on image recognition [0004] The earliest graphic password scheme based on image recognition is the Déjà Vu scheme proposed by Dhamija et al. at the USENIX Security Annual Conference in 2000, which uses random artistic pictures generated by hash functions to replace meaningless strings. When authentica...

Problems solved by technology

[0011] The purpose of the present invention is to overcome the problem that the current text password system in the above-mentioned prior art is not easy to memorize, and the security is not high, and too many graphics input restrictions in the graphic password are inconvenient to input, and the excessive number of graphics requires a large amount of storage space. Graphical features are too complex and difficult to memorize, anti-shoulder peeping performance is not good, can not effectively prevent spyware, can not resist brute force attacks, password space is small and other defects, and provide a password generation system and method based on slice graphics, this new type of graphics The password scheme only needs to occupy a small amount of storage space for storing password graphics, and it can be used as conveniently as a text password, and the password is easier to remember and recall than the text password series. It has the advantages of simple and convenient operation, large password space, easy memory, and storage space Advantages such as small size and anti-shoulder peeping
