PROBLEM TO BE SOLVED: To reduce the load of registration and updation work of a multimedia database and simultaneously to quicken those work by utilizing a digital watermark technique. SOLUTION: A data attribute embedding processing part embeds the data attribute or an updation condition into multimedia data through a digital watermark technique, and an embedded data detection processing part automatically detects the data attribute or the updation condition from the multimedia data, stores the multimedia data in a real data storage region by transferring the multimedia data to a real data registration/updation processing part, attaches the storage place to the data attribute or the updation condition, transfers the data attribute and the updation condition to an index data registration/ updation processing part and performs registration/updation processing of the index data storage region.
