A Novel Watermarking Extraction Based on Error Correcting Code and Evidence Theory

Nowadays digital watermarking has played an important role in the copyright protection of multimedia. A new robust watermarking algorithm is proposed with the base of error correcting code (ECC) and data fusion by evidence theory and distortion factor. The algorithm does not need any mask or original image during the extraction and makes the watermark more robust and further more the data fusion composed by a new watermark confidence relatively reduces the volume of the embedding watermark. At last experiments have proved the algorithm is practical.
