PROJECT TITLE :

A Shoulder Surfing Resistant Graphical Authentication System - 2018

ABSTRACT:

Authentication primarily based on passwords is employed largely in applications for pc security and privacy. However, human actions like selecting bad passwords and inputting passwords in an insecure approach are considered “the weakest link” within the authentication chain. Rather than arbitrary alphanumeric strings, users tend to decide on passwords either short or meaningful for easy memorization. With internet applications and mobile apps piling up, people can access these applications anytime and anywhere with numerous devices. This evolution brings great convenience however conjointly increases the likelihood of exposing passwords to shoulder surfing attacks. Attackers will observe directly or use external recording devices to gather users' credentials. To overcome this downside, we have a tendency to proposed a unique authentication system PassMatrix, primarily 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, PassMatrix offers no hint for attackers to work out or slender down the password even they conduct multiple camera-based attacks. We have a tendency to additionally implemented a PassMatrix prototype on Android and allotted real user experiments to guage its memorability and usefulness. From the experimental result, the proposed system achieves higher resistance to shoulder surfing attacks whereas maintaining usability.
