Don't listen to my Keystroke Dynamics!

16th Int.l Summer School on Biometrics and Forensics 2019; International audience; Keystroke Dynamics enables the authentication or identification of users by analyzing their way of typing, e.g. when browsing the Internet. Most studies in the state of the art focus on increasing Keystroke Dynamics Systems performances. In this paper, we address the problematic of avoiding biometric authentication with keystroke dynamics in order to protect users' privacy against unwanted authentication/identification. Experimental results obtained on significant datasets show the benefits of the proposed approaches.
