Information sharing support server, information sharing support system, and information sharing support method

摘要

To support information sharing between terminals existing within a short distance from each other while a burden on a server administrator is prevented from increasing or decreased. An information sharing support server 40 includes a server data transmission and reception control unit 412 which recognizes identifiers of sending terminals 30a to 30b associated with identifiers of originating terminals 10a and 20a (STEP 446, STEP 466), recognizes identifiers of terminals associated with the relevant identifiers of the sending terminals (STEP 448, STEP 450, STEP 468), and transmits data to the relevant terminals (STEP 452, STEP 470).
