This paper presents initial research into investigating the viability of large-scale biometric technology implementations. Literature provides considerable support to technical aspects of biometric viability, but there appears to be limited research concerning the equally significant hurdles facing social acceptance. It is argued that any large-scale social acceptance of biometrics will need to be achieved through a combination of legal and architectural control mechanisms established to allay social fears concerning the opportunities for the abuse of biometric systems. This paper considers a cross-section of legal concerns and controls before outlining research questions to be examined and a methodology for a discovery of issues and viable control mechanisms.
