Abstract: A predictive physical access control and security intervention system includes a credential device, indicia sensors, portal actuators; and a data store of historic and predicted travel events, whereby out of norm behaviors trigger elevated security intervention processes. A system detects, identifies, and measures occupancy and transit patterns of identities within and through a spatial volume. A processor performs statistical calculations of dwell time, movement patterns, path vectors, frequency of entry or exit, and transmission of attribute assertions containing trusted information to subscribers. The method transforms radio signals emitted by personal communications and identity devices into metrics of human traffic patterns, behavior conducive to commercial and security interests, and provides identity attributes containing trusted information to identity service subscribers.
