Abstract

Wearable devices that capture users' rich information regarding their daily activities have unmet authentication needs. Today's solutions, which primarily rely on indirect authentication mechanisms via users' smartphones, thus cumbersome and susceptible to adversary intrusions. Even though there have been some efforts trying to fill this gap, they either rely on some superior sensors, such as cameras and electrocardiogram (ECG) pads, or are awkward to use, e.g., users are asked to perform some pre-defined movement/gesture for authentication. Therefore, an authentication mechanism for wearable devices that is accurate, robust, light-weight and convenient is in dire need.
