COMMUNICATION SYSTEM, SERVER, AND AUTHENTICATION METHOD

WIPO Patent Application WO/2015/178164

A1

Provided is a communication system in which a beacon device transmits a beacon signal that includes beacon device identification information for identifying said beacon device and a count value that increases over time. A server associates the beacon device identification information and the count value at a predetermined reference time and stores the result. When a communication terminal receives a beacon signal, said communication terminal performs an inquiry regarding the validity of the beacon device that is the transmission source of the beacon signal using the beacon device identification information and the count value that are included in the beacon signal. The server that responds to the inquiry determines the validity of the beacon device using the reception time at which the inquiry is received, the count value that is included in the inquiry, the reference time of the beacon device that is the subject of the inquiry, and the count value at the reference time.
