In this work, we present SilentSense, a framework to authenticate users silently and
transparently by exploiting the user touch behavior biometrics and leveraging the integrated …

We present CapBand, a battery-free hand gesture recognition wearable in the form of a
wristband. The key challenges in creating such a system are (1) to sense useful hand …

The goal of this work is to enable user authentication via finger inputs on ubiquitous surfaces
leveraging low-cost physical vibration. We propose VibWrite that extends finger-input …

Body-area networks of pervasive wearable devices are increasingly used for health
monitoring, personal assistance, entertainment, and home automation. In an ideal world, a …

With the increased popularity of smartphones, various security threats and privacy leakages
targeting them are discovered and investigated. In this work, we present SilentSense, a …

We present Z-Ring, a wearable ring that enables gesture input, object detection, user
identification, and interaction with passive user interface (UI) elements using a single …

Mobile authentication is indispensable for preventing unauthorized access to multi-touch
mobile devices. Existing mobile authentication techniques are often cumbersome to use and …
