Abstract

An authentication certificate server receives an acquisition request of a confidential document which specifies a URI of a disclosable document obtained by removing a confidential element from the confidential document, the authentication certificate server transmits an acquisition request of the disclosable document to a public server and specifies a dictionary file based on the URI, and if the user has an access authority to the confidential element, the authentication certificate server transmits an acquisition request of a dictionary file to a confidential server. When the authentication certificate server receives the dictionary file from the confidential server and receives the disclosable document from the public server, the authentication certificate server restores the confidential document by returning the confidential element at a position in the disclosable document which position is specified by the dictionary file, and then transmits the confidential document thus restored to the terminal device.
