Passwords are used in the vast majority of computer and communication systems for authentication.The greater security and memorability of graphical passwords make them a possible altative to traditional textual passwords.In this paper we propose a new graphical password scheme called YAGP,which is an extension of the Draw-A-Secret (DAS)scheme.The main difference between YAGP and DAS is soft matching.The concepts of the stroke-box,image-box,trend quadrant,and similarity are used to describe the images characteristics for soft matching.The reduction in strict user input rules in soft matching improves the usability and therefore creates a great advantage.The denser grid granularity enables users to design a longer password,enlarging the practical password space and enhancing security.Meanwhile,YAGP adopts a triple-register process to create multi-templates,increasing the accuracy and memorability of characteristics extraction.Experiments illustrate the effectiveness of YAGP.
