摘要

PROBLEM TO BE SOLVED: To provide a storage system enabling prevention of tracing of information related to an IC tag.

SOLUTION: The IC tag 10 creates a provisional ID different at each fixed distance based on an original ID, and transmits a wireless signal including the created provisional ID and data. A copying control device 30 receives the provisional ID and data from the IC tag 10 via an IC tag reader 20, and transmits a storage address request, the provisional ID contained in a storage assignment device 40. The storage instruction device 40 receives the storage address request, including the provisional ID, transforms the storage address request containing the provisional ID into the original ID, creates the storage address based on the transformed original ID, and transmits the storage address reply, containing the storage address created. The copy control device 30 receives the storage address reply from the storage instruction device, reads out the storage address contained in the received storage address reply and transmits the store request containing the read out storage address and data to a storage device 60 via a network 50.
