Abstract

Smartphones have gained huge popularity and rapidly changed the way of people’s living habits and communication style. Despite the widespread adoption, there is a big challenge to protect data security on smartphones. This is because phone users often store their personal data (e.g., images) and proceed sensitive tasks (e.g., financial operations) on the device. To secure the device from unauthorized access, designing an appropriate unlocking mechanism is an expected solution. To complement existing schemes, we advocate that combining behavioral biometrics can enhance the security of unlocking mechanisms. In this work, we develop a double-click-based unlocking scheme (DCUS), which allows users to unlock the phone by double clicking on the pre-selected location on an image. For verification, DCUS has to check selected images, image location and behavioral features of double-click action. In the user study, we involve 40 participants and explore some common supervised algorithms. The results demonstrate that participants can achieve a good success rate (over 96%) with positive feedback.
