Passwords are the security primitives used in proving a user’s identity online. Passwords can be grouped as alphanumeric passwords, biometric passwords and graphical passwords. Graphical passwords are more secure than alphanumeric password. In this paper, we present a secure and user friendly graphical password authentication system named as RIP (Randomized Image Passwords) which is based on randomizing the visual objects used as passwords so that each time the user gets different image for login. This adds security since the visual objects do not maintain a fixed position on login image. In order to avoid shoulder surfing attack and spyware attack, a circumnavigation mechanism is proposed for which we will be using QR codes. The proposed authentication method using RIP and QR codes can be a solution to security threats like shoulder surfing attack, attack using malwares such as screen recorders, which are the major security issues associated with graphical password schemes. This scheme offers reasonable security, user friendliness and will fit well with many practical applications.
