Abstract

An information management method and an information processing device functioning as a node are provided to enable an effective use of information distributed to, and shared with, a plurality of nodes on a network and to enable maintenance of security against leakage of information by controlling information retention. This management method of information gathers information distributed to, and shared with, a plurality of the nodes on a network and holds the information in a state accessible from other nodes to a temporary information memory unit when generating restored information. The information management method is also characterized in setting a flag for showing a history of the information and immediately discarding the information in the case that the retention of restored information becomes improper from a view point of contents of the flag.
