CHAPTER 12 Behavioral Biometrics

The computing and data revolutions have come at a cost of ever easier cybercrime. Computer security has thus far been insufficient to the task. One of the major points of attack is user access control. Systems today remain reliant on a password or some combination of a password and a second factor, perhaps a security token. Efforts to improve on this model, such as biophysical biometrics (like fingerprint or iris scan), have quickly been hacked. Behavioral biometrics—keeping track of the user's behavior, and being more careful when atypical behavior is observed—offers a powerful yet effortless tool in the computer security arsenal that can augment or replace other methods, improving overall security.
