User authentication is one of the significant topics in information security. Commonly used authentication is alphanumeric passwords, biometrics and smart card. At present day upcoming popular method is graphical password. In graphical password systems authentication is based on clicking on image rather than typing alphanumeric strings .The motivation to develop graphical password is the fact that human can remember picture better than text.
