Abstract
In recent years there has been much progress in the development of facial
recognition systems. The FERET series of tests reported the black box performance
of several such systems working on stored face images. Much less effort
has been spent in studying the behaviour of systems under realistic conditions
of use. In this paper we describe and analyse the result of a trial of
a door access control system based on a model-based approach. The trial
consisted of 10 registered users making over 200 accesses over a 2 week
period. We describe the internal failure modes and the performance characteristics
of the system and identify inter and intra-person dependencies and make
recommendations for future work.
