Abstract
Secure physical environments such as government, financial or military facilities are vulnerable to misuse by authorized users. To protect against potentially suspicious actions, data about the movement of users can be captured through the use of RFID tags and sensors, and patterns of suspicious behaviour detected in the captured data. This chapter presents four types of suspicious behavioural patterns, namely temporal, repetitive, displacement and out-of-sequence patterns, that may be observed in such a secure physical environment. We model the physical environment and apply algorithms for the detection of suspicious patterns to logs of RFID access data. Finally we present the design and implementation of an integrated system which uses our algorithms to detect suspicious behavioural patterns.
