Abstract
It is believed that graphical passwords are more memorable than traditional textual passwords, but usually seen as complex and time-consuming for users. Furthermore, most of the existing graphical password schemes are vulnerable to spyware and shoulder surfing. ColorLogin uses color, a method not previously considered, to decrease login time. Multiple colors are used to confuse the peepers, while not burdening the legitimate users. Meanwhile, the scheme is resistant to shoulder surfing and intersection attack to a certain extent. This paper analyzes and evaluates the ColorLogin scheme using some experiments.
