Geo-Location Estimate (GLE) Sensitive Physical Access Control Methods of Operation

摘要

A method operates a server that 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.

1. A method for operation of an Access Control Cloud Server (Server) that controls an actuator operative on a portal responsive to requests from mobile wireless devices, the method comprising:
receiving and storing authentication keys from an App Store for each instance of an installed access control app; receiving via the cellular network an access control request from the authenticated Access Control App which contains an authenticated user id, a Geo-Location Estimate (GLE) coordinate, and a timestamp; determining that the user is allowed access at a geo-location area portal, according to a rule; and encrypting and transmitting an access actuator command to an actuator within a specified area bounding the GLE coordinate of the access request, wherein the Access Control App is signed by a Certificate Authority (CA).
