Patent ID: 8126194

Claim:
A digital watermark embedding apparatus for embedding particular embedding information into multimedia data, comprising: a storing unit that stores in advance at least one embedding function, at least one image converting program, and at least one image processing program that are required for a digital watermark embedding process, and storing in advance combination process information in which a process ID is assigned to each combination of the at least one embedding function, the at least one image converting program, and the at least one image processing program; an embedding process selector that selects, as particular combination process information, one of a plurality of pieces of the combination process information stored in the storing unit; and an embedder that obtains the at least one embedding function, the at least one image converting program, and the at least one image processing program that are included in the selected particular combination process information, embeds the particular embedding information into the multimedia data, and generates determination information for determining the process ID corresponding to the particular combination process information.
