In recent years, graphical passwords have become a viable alternative to the traditional text-based passwords due to their superior ease of recall and potential large password space. However, there is very limited research in classifying and mathematically analyzing the graphical password techniques. In this paper, we conduct a comprehensive study of the existing graphical password techniques. We propose the first taxonomy for graphical passwords methods and discuss the important elements in designing them. We present a mathematical analysis of the graphical password space. Finally we present a new graphical password scheme.
