GRAPHICAL PASSWORD AUTHENTICATION USING PCCP WITH SOUND SIGNATURE

Summary

In graphical password PCCP techniques is strong but not satisfied. In PCCP technique the chances of shoulder surfing attack is more for avoiding shoulder surfing attack dead zone concept is added to it. Using the dead zone in PCCP (At the login phase, images are displayed without shading and users needed to select correct click points for authentication.) we create the password is more strong secure and also adding sound signature for forgot password. User must select sound at the time of registration. When user not memorize the password that time the user click on forgot password button then system gives sound clip if user play the correct sound then system gives the permission to create new password and gives the image sequence for creating password otherwise system goes through exit mode. Dead zone is concept take for avoiding shoulder surfing attack. Shoulder surfing concept is if user enters the password and select the images sequence of his password and any person standing backside of user and looking the password sequence then there is many chances of hack your account by using guessing attack. This concept is shoulder surfing. But using the dead zone concept we can avoid that attack. The dead zone is some particular area that is allocated user on registration time which is store in all image sequence. When click on that area the system shows image sequence from starting image. If user enter the password and some person looking that then user can select the wrong click point then system gives wrong image sequence to user which is dead zone is present then user click on dead zone then again system gives correct image sequence. This process can be repeated many time then this person is confused and very hard to crack password by using shoulder surfing attack.
