Abstract
In an information processing device, error detection information is generated from additional information and a header is generated from error detection information. An encoded header is then generated by appending a header-error correction code to the header and encoded additional information is generated by appending an information-error correction code to the additional information. Finally, an information-appended image is generated by integratedly appending the encoded header and the encoded additional information to the target image.
