This paper proposes a new asymmetric watermarking system. Digital watermarking is a method to imperceptibly embed certain information in digital multimedia data. Watermarking systems are classified as symmetric and asymmetric ones. The former uses the same key for encoding and decoding and is suitable for private applications in the sense that the key has to be maintained private among the authorized embedder and detectors. The latter, which uses different keys for encoding and decoding, is for public applications.
