Behavioral Biometrics Keystroke Dynamics Speaker Recognition

Authentication/Verification vs. Identification One Much Easier and Faster Offers multilayer (two factor) security

Speaker Recognition Recognizes tone, rhythm cadence Text (in)dependence Simple Inputs Resistant to Coercion

Problems/Issues Ambient Noise Voice Recordings Enrollment Time Temporary Changes Change Over Time

Keystroke Dynamics History Typing verification Seamless for user Can lock out or warn in mid-session

Problems/ Issues Enrollment Variable environment Variable moods/ abilities Could be good Hackers - timing information can greatly narrow the time to hack passwords Keyloggers Once disclosed, no recovery
