Graphical Password to Avoid Shoulder Surfing

Traditional text-based passwords are vulnerable to attacks such as guessing, brute force, and particularly shoulder surfing, where an attacker can observe and replicate a user’s password entry. To overcome these limitations, graphical password authentication provides a more secure and user-friendly alternative by leveraging human ability to remember images more effectively than text. In this project, a graphical password scheme with spin-wheel/colour-wheel design is implemented to resist shoulder surfing attacks. Users create a personalized password by selecting sequences of colors , patterns, or positions on an interactive graphical interface rather than typing characters. During authentication, the interface dynamically changes its layout, ensuring that even if an attacker observes the login process, the actual password sequence cannot be easily inferred. This approach enhances security while maintaining usability, making it suitable for applications where secure and intuitive authentication is essential.
