  • System and method for classifying regions of keystroke density with a neural network
    Patent number: 7620819
    Abstract: We develop a system consisting of a neural architecture resulting in classifying regions corresponding to users' keystroke patterns. We extend the adaptation properties to classification phase resulting in learning of changes over time. Classification results on login attempts of 43 users (216 valid, 657 impersonation samples) show considerable improvements over existing methods.
    Type: Grant
    Filed: September 29, 2005
