This evolution brings great accessibility but also increases the probability of exposing passwords to shoulder surfing attacks, Authentication based on passwords is used largely in applications for computer security and confidentiality. However, human actions such as choosing bad passwords and inputting passwords in an insecure way are regarded as ”the weakest link” in the authentication chain. Rather than arbitrary alphanumeric strings, users incline to choose passwords either short or meaningful for easy to memorization When users input their passwords in a public place, they may be at risk of attackers stealing their password. An attacker can capture password by direct observation or by recording the individual’s authentication session. This is referred to as shoulder-surfing and is a known risk, of special anxiety when authenticating in public places Attackers can observe directly or use external recording devices to collect users’ credentials to avoid this problem the process of pass matrix, based on graphical passwords to resist shoulder surfing attacks. With a one-time valid login indicator and circulative horizontal and vertical bars covering the entire scope of pass-images, Pass Matrix offers no suggestion for attackers to figure out or narrow down the password even they conduct multiple camera-based attacks.
