Information management system, information processing device, and program

摘要

An information management system comprises: an external device a comprising interactive communication unit that interactively communicates with an interactive communication device through a public telephone line; an information processing device connected to the external device in a communication-practicable manner; and a third storage unit that stores utilization data, which is accessed by the external device and the information processing device. When a period specified by a start and end of a communication performed by the interactive communication unit of the external device and a period specified by the start and end of utilization of the utilization data overlap with each other, the utilization data are correlated with the communication of the interactive communication unit.
