Authentication, Graphical Passwords, Shoulder Surfing Attack


In this computing world, computer security and confidentiality can only be gained by providing authentication based on passwords. It becomes hectic to memorize textual passwords that are too long just for the sake of security. Thus allowing some users to choose small memorizing passwords which tend to be insecure and are considered as the weakest link in authentication chain. Graphical passwords are always considered as a flipside to the alphanumeric or textual passwords. The advances made in web applications and mobile apps empower user to access these applications anywhere without any time constraint. This improvement brings great comfort but at the same time thus increasing chances of exposing passwords to the Shoulder Surfing attack. In shoulder surfing attack, attacker observes directly or with the help of external devices for gathering user credentials. To blow away this problem a novel authentication system, PassMatrix with color authentication system to resist shoulder surfing is been represented in this paper. With a onetime valid login indicator and circulative horizontal and vertical bars covering the entire scope of pass-images and choosing color sequence, PassMatrix with color authentication system offers no evidence for attackers to discover the password even if multiple attempts of camera-based attacks were performed.
