Web-Based Keystroke Dynamics Identity Verification Using Neural Network
Sungzoon Cho, Chigeun Han, Dae Hee Han, Hyung-Il Kim · Journal of Organizational Computing and Electronic Commerce · 2000
Password typing is the most widely used identity verification method in Web based electronic commerce. Due to its simplicity, however, it is vulnerable to imposter attacks. Keystroke dynamics and password checking can be combined to result in a more secure verification system. We propose an autoassociator neural network that is trained with the timing vectors of the owner's keystroke dynamics and then used to discriminate between the owner and an imposter. An imposter typing the correct password can be detected with very high accuracy using the proposed approach. This approach can be effectively implemented by a Java applet and used for the Web.
