An Improved Methodology towards Providing Immunity against Weak Shoulder Surfing Attack

摘要: In a conventional password based authentication system, an adversary can obtain login credentials by performing shoulder surfing. When such attacks are performed human users with limited cognitive skills and without any recording device then it is referred as weak surfing attack. Existing methodologies that avoid attack, comprise of many rounds which may be the cause fatigue to general users. this paper we have proposed methodology known Multi Color (MC) method reduces number in session half previously methodologies. Then using predictive performance modeling tool shown MC immune against attack also improves existing security level.
