An information processing system of the present invention records information on distribution when information is distributed so that an information distribution route is traced later. In the information processing system, when information held in an information holding section is distributed from an information distribution section to a different information intervention system, a distribution sensing section senses it and records its distribution history in a distribution history holding section. When an information tracing instruction is given, a history collection section fetches distribution histories related to the information to be traced from the distribution history holding section, detects the destination, and instructs the destination information intervention system to trace the information. In response to the instruction, history information is collected from the different information intervention system and is stored in a collected history holding section. A tracing analysis section analyzes the collected history information and displays the distribution route, etc., on a tracing result display section.
