Abstract: A server is coupled to a network controlling door actuators at physical geo-locations. The server receives through a wireless communication network a request to enable physical access at a portal using a secure channel and a geo-location estimate from a mobile device. A circuit of the mobile device receives radio signal magnitude, phase, and power from at least one transmitter and authentication input from a user interface. Dual secured communications paths protect the server on its separately provisioned request channel and actuator command channel. Each legacy electronically controlled access portal is enabled to support smartphones without installing a replacement multi-band radio frequency reader at the geo-location.

Abstract: A personal electronic device enables access to and occupancy of a secure space by providing measures of behaviors, personal attributes, history of transactions and movements that are used to validate continuous authentication and authorization of the device's possessor. This addresses the vulnerability of a misplaced, lost, or stolen electronic credential. An anchor point is a physical measurement of personal physical identity such as voice recognition, fingerprint, iris scan, chemistry, or other biometric. Continuity from an anchor point is measured by GPS way points, financial transactions at familiar vendors, outgoing text messages or passphrases, gait analysis, heart rate, EKG rhythm, or transit time. A request for access is presented upon a challenge based on proximity to a portal location. A digital credential is used to encrypt two or more of the continuity milestones and an anchor point which can be matched against a previously stored or dynamically generated expected value.
