Application of Self Organizing Maps for the Integrated Authentication Using Keystroke Timings and Handwritten Symbols

摘要

Recently, security of the computer systems becomes an important problem. Almost all computers use the password mechanism for the user authentication. But password mechanism has many issues. In this paper, we propose a kind of biometrics authentication method using the combinations of keystroke timings and pen pressures. For this method, selection of the phrase for key input and the symbol for pen input is important. We analyzed the keystroke timings and pen pressure using Self Organizing Map (SOM). We examined the effectiveness of this method with the authentication experiments using the map organized by SOM.
