Is there a system to recognize the owner of a password by typing style?

Question

Passwords

Obviously, each of us types our password slightly differently, but is there a program / script that learns and determines not only the correctness of the input, but also monitors the typing style at the same time?

Answer 1

Explain, it is very interesting how the word password, for example, can be typed in different ways? )

Answer 2

As I understand it, you mean the typing speed (i.e., the intervals between keystrokes). I won't google, but I don't think so. It's too unreliable. If the form will swear at my every delay in entering, it will get me. You need to keep track of who owns the password, and how to type it already - there is no difference.

Answer 3

I have seen a lot of theoretical developments (articles). But in practice, this method has very poor performance (FALSE_POSITIVE; FALSE_NEGATIVE) compared to other biometric methods. I remember in the articles even the minimal consumption of coffee or alcohol, not to mention the fatigue of the hand by the end of the working day, led to authentication failures. (term - "keyboard handwriting")
