Abstract
We present a novel approach to improving the security of passwords In our approach, the legitimate user's typing patterns (e.g, durations of keystrokes, and latencms between keystrokes) are combined with the user's password to gen-erate a hardened password that is convincingly more secure than conventmnal passwords against both online and offime attackers. In additmn, our scheme automatically adapts to gradual changes in a user's typing patterns while maintain-ing the same hardened password across multiple logms, for use m file encryption or other applications requiring a long-term secret key Using empirical data and a prototype im-plementatmn of our scheme, we give evidence that our ap-proach Is viable m practice, m terms of ease of use, improved security, and performance
