Title
High-Entropy visual identification for touch screen devices
Abstract
We exhibit a system for improving the quality of user-derived keying material on touch-screen devices. We allow a device to recover previously generated, highly entropic data suitable for use as (part of) a strong secret key from a user's act of identifying to the device. Our system uses visual cryptography [21], using no additional electronics and no memorization on the part of the user. Instead, we require the use of a transparency overlaid on the touch-screen. Our scheme is similar to the identification scheme of [22] but tailored for constrained, touch-screen displays.
