Abstract
In this paper, we investigate a method for detecting impersonation by continuously authenticating the individual without stressing the user after authentication using IDs and passwords. As a method to prevent the occurrence of fraud by spoofing, this paper reports the results of a study of an identity authentication method that uses keystroke timing and sound based on keystroke information at the time of document creation.
The authentication experiments were conducted by changing the keystroke timing by making the user aware of the keystroke timing in the measurement conditions. Authentication experiments were conducted using the three keystroke sounds that are characteristic of Japanese input: “conversion”, “confirmation” and “newline”. The authentication success rate of the authentication experiment using keystrokes was 63%, and the authentication success rate of the experiment using keystroke sounds was 79%. We think that this method is sufficient as a stand-alone authentication method, and we will continue our research for multimodal authentication using features obtained from keystroke information.
