Abstract
A beacon device establishes a network connection with a user computing device. The beacon device determines the received signal strength indicator of the user computing device (the 'reverse RSSI') and transmits it to the user computing device, which determines the received signal strength indicator (the 'RSSI') of the beacon device, and saves the RSSI with the reverse RSSI as a data pair. At a later time, the beacon device determines a subsequent reverse RSSI and transmits it to the user computing device, which determines a subsequent RSSI, and saves the subsequent RSSI with the subsequent reverse RSSI as a data pair. If the user computing device determines a correspondence in the changes of the RSSI values and reverse RSSI values in the two data pairs, a transaction between the two devices is allowed. If correspondence does not exist, then the user computing device terminates the network connection.
