- (a) in response to a request from a requester, embedding perceptually unrecognizable code information using a digital watermark in perceptually recognizable fixed-pattern data mounted in said multimedia data including at least one of character data, still image data, moving image data and audio data, and sending said multimedia data embedded with said code information to the requester;
(b) registering information related to said multimedia data embedded with said code information in the database, in correspondence with said code information; and
(c) in response to a search request from a requester, searching said database on specified code information to extract information on said multimedia data corresponding to the specified code information, and sending the extracted information to the requester, wherein said fixed-pattern data, embedded with said code information using said digital watermark, is a mark image in the form of a still image.

Abstract
A mark management server embeds a mark ID and so on in a specified mark image in response to a mark request from a WWW server, registers information related to a Web page corresponding to this mark ID in a mark management DB, and sends the mark embedded with the information to the server. The server attaches this mark to a created Web page, and registers the Web page in a Web page DB. A client terminal acquires a Web page from the server, reads information embedded in a mark, and issues a request for a search according to the mark to the server. The server references the DB, and sends information associated with a Web page corresponding to a specified mark ID to the terminal.
