A multiple watermarks embedding scheme based on multi-stage vector quantisation (VQ) is proposed. A reference watermark is generated first by referring to all the fake watermarks and the real one. Then all the watermarks except the real one are embedded into each stage of the multistage VQ system. The generated keys can be assigned to the related users to share the hidden information. Combining all the extracted watermarks, the real watermark will appear. With the fake watermarks and the structure of the multistage vector quantisation, the proposed scheme has superior features than traditional VQ-based watermarking schemes not only in security, encoding time, and codebook storage space, but also in secret sharing ability. |
