Session Authentication Using Color Schemes and Images

Authentication is the first step in information security. It requires the user to set a password and remember it at the log in time. Textual passwords are the most traditional schemes that are used for providing security, but textual passwords are vulnerable to dictionary attacks, shoulder surfing, and spy ware. Graphical password schemes overcome the shortcomings of textual passwords, but they are vulnerable to shoulder surfing attacks. To address this problem, text can be used in combination with the colors and images to generate session passwords, thereby making a stronger authentication scheme. In this project the authentication scheme uses colors and text for generating session passwords.
