Authentication, the process of identifying an individual, currently plays a critical role in security systems. Graphical password schemes are believed to be more secure and resilient to dictionary attacks than traditional textual passwords. The authors designed a graphical password system with the novelty of incorporating the sense of touch via haptic technologies. Using haptics, the system utilizes the physical attributes captured during human-haptic-computer interactions. Parameters such as pressure and velocity can be handled as 'Hidden' features to increase the resiliency of the system.
