Construction Of Topological Graphic Passwords By Hanzi-gpws

Graphical passwords are familiar with people in nowadays, such as 2-dimension code, face-authentication, finger-print authentication, and so on. In which 2-dimension code is widely used in everywhere of the world. In this paper, we design a new-type of graphical password, called Hanzi-gpw, which is the abbreviation of Hanzi graphical password, it is differ from the existing graphical passwords, since Hanzi-gpws are saved in computer by algebraic matrix. We realize the transformation between text-based passwords (TB-paws) from Hanzi-gpws. Several methods for generating TB-paws from Hanzi-gpws are introduced; these methods are based on topological structures and graph coloring/labelings. To use of Chinese characters to design passwords may appeal to most Chinese people. By the way, we find new graph labelling in which some mathematical conjecture are produced.
