The security is main concern in each and every application. Graphical authentication provides secure way of authorization. Goal of knowledge specific authentication system is to provide support for user in selecting passwords for greater security. Here we are using 2D coordinates to secure a picture and generate a password. Additionally the pictures in x and y coordinates change randomly and hence it is difficult to find the original picture. Our base paper provides solution against the attacks possible on these approaches “Persuasive cued click points”,” Cued click points ” and “Pass points”. We propose a system which removes the problem of shoulder surfing.
