Algorithm for Touchscreen Mobile Device User Authentication by their Gesture Recognition

Required to work out a method by which one can verify the user of a touch screen display mobile device with an information processor on the basis of their gestures. The work should include a review of the keystroke dynamics, mouse movement and biometric-enhanced gestures. Your supposed to make a study on both behavioural biometrics and security measuring systems. An algorithm will be written on the basis of the elaborated method and implemented on computer to show the program performance through examples.
