Enhanced User Authentication Through Keystroke Biometrics
November :: December 2004 -- [report] [presentation] [code]
For our 6.857 (Computer and Network Security) final project, Xia Liu, Chen Xiao, Xiao Yu, and I designed, implemented, and evaluated four different metrics for keystroke-enhanced user authentication. A keystroke-enhanced login system increases security by supplementing the username-password paradigm with authentication of a user's typing patterns. We explored key press duration, relative order of key press and key release times, times between keystrokes, and shift key usage patterns as potential metrics.
