Identity security in biometric systems based on keystroking

The most valuable element of biometric security systems are the personal features of its users. Characteristics of individuals are unique and must be protected. We focus in this paper on methods of protection of user identity in systems based on keystroking. Our approach assumes giving minimal information to adversaries and the best responsiveness of the system regardless of user representation or possible usage. We consider keystroking not only in the context of keyboard, but also touch screen, pin pad and any other input device that could be used for typing. We present as results several complete security solutions that are applicable for software as well as hardware systems.
