Abstract: A method and system looks for patterns in a series of gesture data samples to determine consistency or inconsistency within the data sample. One embodiment includes device authentication using a unique biometric algorithm that provides biometrically enhanced gesture-based authentication using a software only solution. In this embodiment, the system and method provides a mechanism to gather user gesture timing data, and to analyze and abstract the data into a non-repudiated template against which future gesture timings can be verified.
