Single Sign-On System based on Matching Characteristics of Keystroke
Zhi Xue · Communications technology · 2012
Combining the characteristics of keystroke and user authentication schemes,a single sign-on system based on matching keystroke characteristics is proposed.In the system,the keystroke features are extracted as the biometric when user logins,which is used as an important criterion for legitimacy and effectiveness of the identity information.According to the characteristic of normal distribution and the theory of interval estimation,the interval of characteristic value for average keystroke time and keystroke speed is calculated with the given confidence level.Finally,the user's keystroke characteristics are matched in accordance with the statistical model.
