Abstract or Summary:
We present our work in behavioral biometrics employed in the emerging contexts of gesture-based interfaces. We discuss novel approaches to authentication in signature, multi-touch gesture, and full body in-air gesture. Our work addresses security in these contexts not only in term of technical performance but also in terms of pleasurable interactions between user and system. We highlight opportunities to reframe security topics through ‘natural’ interactions. We also raise questions as to how to evaluate the usability of such approaches and how to incorporate these considerations into the evaluation of overall security.
