Exploring Topological Graph Passwords of Information Security by Chinese Culture

Abstract

Graphical passwords are used in the world. Several kinds of topological graphic passwords (Topsnut-GPWs) are designed by using disconnected topology graphs in this paper. Our methods for the construction of Topsnut-GPWs can be transformed into efficient algorithms, and the spaces of Topsnut-GPWs are large and complex for withstanding attacks. We show that the mathematical modulus (Hanzi-graphs) of Chinese characters for making new Topsnut-GPWs that may be easily accepted by Chinese people.
