Hand Vein Biometric Authentication in Optical Multi-touch Systems

Multi-touch systems and their applications are entering a mainstream phase where fast access to visual data and collaborative environments are key factors for an informational age. However, most systems are envisioned as public workstations where resources are shared equally between the users with few or no restrictions on the content delivered by the applications. While real-time identification of the users of a multi-touch system is a difficult subject to tackle, authentication using biometric parameters could provide a hierarchy based content management system. Based on previous research in both hand vein biometric detection and multi-touch systems, this paper describes a hand vein authentication device usable in a touch/object sensing multi-user collaborative environment.
