In shoulder surfing attack, an unauthorized user can fully or partially observe the login session. To avoid this attack, the authors propose an intelligent user interface, known as color pass. This proposed system based on partially observable attacker model, i.e. the attacker can partially observe the login procedure. Classical PIN entry is a popular scheme because it greatly balances the usability as well as security aspects of a system. Color pass interface is easy and safe for any genuine user.
