摘要

PROBLEM TO BE SOLVED: To improve a correctness factor of a digital watermark information extracted from information contents by error-detecting and encoding real information to be intrinsically embedded, as a flag showing that the information is already watermarked. ;SOLUTION: An information decoding device 8 is comprised of an error detection processing part 11 and an error correction processing part 13. The error detection processing part 11 adopts, in the preprocessing, extracted information 7 extracted from the received digital information as an input, and calculates the number of errors in the extracted information 7, and if the number of errors is zero, the error detection processing part 11 outputs an intermediate code 12 obtained by decoding an error detection code or an error correction code embedded by the information encoding device as a digital watermark information. Moreover, if the number of errors is one or more, a unprocessed watermark flag 9(=1) is outputted. The error correction processing part 13 adopts as an input an intermediate code 12 outputted when no error exists in the error detection processing part 11, and outputs real information 10 obtained by decoding the error correction code.;COPYRIGHT: (C)2000,JPO
