Review on Color Password to Resist Shoulder Surfing Attack

Since conventional password schemes are vulnerable to shoulder surfing, many shoulder surfing resistant graphical password schemes have been proposed. However, as most users are more familiar with textual passwords than pure graphical passwords, text-based graphical password schemes have been proposed. Unfortunately, both the text-based password schemes and graphical password schemes are not secure and efficient enough and not adopted. Textual passwords are the most common method used for authentication. But textual passwords are vulnerable to eves dropping, dictionary attacks, social engineering and shoulder surfing. Graphical passwords are introduced as alternative techniques to textual passwords. Most of the graphical schemes are vulnerable to shoulder surfing. To address this problem, text can be combined with colors to generate secure passwords for authentication. The user passwords can be used only once and every time a new password is generated. In this paper, the user propose an improved text-based shoulder surfing resistant graphical password scheme by using color PIN entry mechanism which are resistant to shoulder surfing. In the proposed scheme, the user can easily and efficiently log in into the system. This proposed work gives more security over the password from shoulder surfing and accidental log in.
