PROBLEM TO BE SOLVED: To output a first image in optimal status by preventing deterioration in the quality of the first image on the basis of attribute information embedded in a second image. SOLUTION: First image data are read out of a document database 106 and second image data are read out of an image database 108 by a control part 107 in a distribution server 101. Besides, pointer data are prepared for showing where the first image data are stored on the document database 106. An electronic watermark embedding part 109 embeds the attribute information such as pointer data on the first image by using invisible electronic watermark technique to the second image data. An encoding part 110 collects the second image data, in which the attribute information is embedded, and the first image data as one piece of data as archive data. The archive data collected into one are transmitted to a distribution client 102. |
