Patent attributes
One or more beaconing devices transmit synchronized changing beacons. The changing beacons trigger execution of an application that is installed but closed or not running on a mobile device, that is in wireless beaconing range of a beaconing device, and that has registered the changing beacons with the mobile device operating system (“OS”) to trigger execution of the application upon receipt of the changing beacons. The changing beacons also keep the executing application running by resetting OS policies for closing the application when it is running with the mobile device in a locked or standby state. The application may perform different procedures and different times with the beaconing device or other devices including authorizing access to a secured resource when the mobile device is far away from the beaconing device, and confirming intent to access the secured resource when the mobile device is close to the beaconing device.
