Alphanumeric passwords are the most commonly used way of authenticating users in computer systems. One of the disadvantages of alphanumeric passwords is that they are hard to remember. Image passwords have been proposed to aim to make passwords more memorable and easier for users to use and, for this reason, it is more secure. Furthermore, most of the existing graphical password schemes are susceptible to spyware and shoulder surfing. This paper proposes a new graphical password authentication scheme resistant to peeping attack.
