Graphical Password Scheme Resistant to Shoulder Surfing

Abstract

We propose another graphical secret key plan. It is characterized as test reaction distinguishing proof. Henceforth, a secret word in our plan is time-variation. Client who knows the secret key can meet the test and to react effectively. As a result, our graphical secret key plan is shoulder-surfing safe. An assailant still can't tell what the secret key is, regardless of the possibility that he/she has taped a client's login procedure. Essential investigations on our graphical secret key plan demonstrated the plan is promising.
