Abstract:
By deciding whether a beacon device is authentic based on a distance between a position, which is represented by current position information obtained by a handheld wireless terminal, and a position, which is represented by position-of-installation information registered in a server, fraudulent use of the beacon device can be prevented. Accordingly, reliability of a communication system including the beacon device is upgraded, and a service such as an electronic coupon can be safely provided.
Abstract:
A communication system includes: a beacon device which is connected to an electronic appliance; and an information terminal. In the communication system, the beacon device retains in advance authentication information that is used when authentication of the electronic appliance under monitoring is performed and transmits a beacon signal including the authentication information, if the condition of the electronic appliance has changed. Moreover, in the communication system, the information terminal, upon receiving a beacon signal including the authentication information, performs authentication using the authentication information and informs its user of a condition of the electronic appliance for which the authentication is done.
