Abstract
A registration device registers, in an encrypted file, records in which at a least key item among a plurality of items that is a key during a retrieval is encrypted. At this time, the registration device generates encrypted data of entire key items by encrypting the data of key items in character units and then combining. The retrieval device executes a complete-match and partial match retrieval from the encrypted file using an encrypted retrieval key in which a retrieval key that has been given as a retrieval condition has been encrypted in character units and then combined.
