At a step S, the PDA transmits a request for preservation of the content to the server. At a step S, the server generates a preservation ID based on a user ID for identifying the user of the PDA and based on a content ID for identifying the content, and issues the preservation ID to the PDA. At the next step S, the server stores the issued preservation ID in a preservation-ID database by associating the preservation ID with the content ID. At a step S, the PDA receives the issued preservation ID from the server and stores the preservation ID in a memory. The present invention can also be applied to an information management system.
