PROBLEM TO BE SOLVED: To appropriately share a file between limited users.SOLUTION: A file sharing system S includes: a beacon transmission device 1 for transmitting a beacon signal by short-range radio communication; a plurality of portable terminals 2; and a server 3. Each of the plurality of portable terminals 2 is configured to, when receiving the beacon signal transmitted by the beacon transmission device 1, estimate a distance between the portable terminal and the beacon transmission device 1 on the basis of the radio wave intensity of a radio wave corresponding to the beacon signal, and to, when the estimated distance is less than a predetermined distance, transmit a participation request for making a request for participation in a group to the server 3, and to receive the address of a storage area corresponding to the group from the server 3, and to perform access to the storage area on the basis of the received address. The server 3 is configured to, in response to the reception of the participation request from the portable terminal 2, generate the address of the storage area corresponding to the group, and to notify the portable terminal 2 which has transmitted the participation request of the generated address.SELECTED DRAWING: Figure 1 |
