Abstract: In the conventional technique for mainly performing access control, an entity (an individual) which provides information cannot grasp a state of use of personal information. In the conventional technique for encrypting stored data, a decryption key is always required when personal data is used and the personal data is not protected once decrypted. The invention constitute a system such that a purchase history is collected according to an anonymous ID and a response from a member card or an agent server is required for operation for associating the anonymous ID with a personal ID. Personal data itself is not encrypted but stored in a plain text with the personal ID and the anonymous ID as keys such that the anonymous ID is regenerated every time the anonymous ID is associated with the personal ID on a server side. At this point, the anonymous ID serving as a collection key for the purchase history, which is accumulated concurrently, is also regenerated.

Abstract: A destination-of-movement candidate acquiring unit of a user terminal selects one of a plurality of storage systems, which has a shorter response time. A destination-of-movement candidate adding unit of the user terminal adds, to an access request, destination-of-movement candidate information specifying the selected one storage system. A destination-of-movement candidate managing unit of an origin-of-movement storage system manages frequency of the access request from the user terminal for each candidate for the destination of movement. When the frequency of the access request exceeds a predetermined value, the destination-of-movement candidate managing unit instructs a file system interface to read data and then move the read data to the candidate for the destination-of movement-for which the frequency of the access request has exceeded the predetermined value. As a result, the user terminal is able to access the storage system having a shorter response time.
