Abstract: A digital watermarking sharing algorithm based on Lagrange interpolation formula is proposed. We divide the field of the image into n shares, and then we also make the information of digital watermarking into n shares by the algorithm. We embed the shared digital watermarking by Least Significant Bit method, and only need part shares in the recover progress. Experimental results show that this algorithm is robust for cutting. Watermarking sharing algorithm is an effective way to protect the copyright of multimedia data.

Key words: information hiding, digital watermarking, interpolation formula
