The Authentication of the Computer Users Based on Levenberg-Marquardt Algorithm
Wang Chen · Journal of Shanxi Teachers University · 2005
In order to protect computer system, password is the most widely used method to control the access of computer system by authenticating the users′ identity. However, the policy of password is vulnerable to impostor attacks due to its simplicity. Therefore, the original intention of keystroke dynamics is to provide a convenient and effective protection on password verification. In keystroke dynamics, the characteristics of a user′ keystrokes is captured when password is being typed, and is analyzed by algorithms to automatically recognize the authentic identity. What is critical for such an auxiliary identity authentication is to find a recognition algorithm with high accuracy and high speed. In this thesis, these problems are explored in depth, and Levenberg-Marquardt algorithm is adopted for data analysis.
