摘要：Passwords provide security mechanism for authentication and protection services against unwanted access to resources. One promising alternatives of textual passwords is a graphical based password. According to human psychology, human can easily remember pictures. In this paper, I have proposed a new hybrid graphical password based system. The system is a combination of recognition and pure recall based techniques and that offers many advantages over the existing systems and may be more convenient for the user. My approach is resistant to shoulder surfing attack and many other attacks on graphical passwords. This scheme is proposed for smart hand held devices (like smart phones i.e. PDAs, ipod, iphone, etc.) which are more handy and convenient to use than traditional desktop computer systems.
