PROBLEM TO BE SOLVED: To fully maintain the secrecy of data and to achieve fast data searches.

SOLUTION: An application server provides identification information to a first data file (step S309) and records first encrypted data in the first data file (step S310, S311). The application server creates second data including information on the items of the first data and the identification information (step S314), encrypts the second data (step S315), and records the second encrypted data in a second data file (step S316).
