Performance of the K Nearest Neighbor in Keyboard Dynamic Authentication

Securing personal information and combating impersonation are nowadays considered as national priorities. Biometrics, the physical traits and behavioral characteristics that make each of us unique, promises an effective solution to our security needs. It is the aim of this paper to explore the use of the K nearest neighbor as a cheap and an unobtrusive way of reinforcing the de facto security mechanism which is the textual password.
