摘要

An information management system (10) is provided with a portable communication terminal (100) capable of acquiring position information, a community medicine databank system (120), and a medical institution (130) provided with a transmitter (131). The portable communication terminal (100) transmits a space-time tag comprising time information and position information, and a terminal ID to the community medicine databank system (120). A space-time ID information processing unit (121) of the community medicine databank system (120) generates, in a per-use folder, a space-time ID from a plurality of space-time tags, and stores the generated space-time ID in a space-time ID information DB (122). A terminal device (133) of the medical institution (130) transmits the position information and time information about the portable communication terminal (100) to the community medicine databank system (120). A collation processing unit (124) collates information from the portable communication terminal (100) and information from a used terminal (141) and, if a request for information transmission is valid, transmits the information to the used terminal (141).
