Abstract A digital watermarking sharing algorithm based on vector secret sharing scheme is presented, which applies the thought of vector sharing to digital watermarking. The algorithm disturbs both the original watermark and the sharing block watermark before hiding the original watermark. The sharing processing has the effect of disturbing too. So the algorithm has highly security. Experimental results show the algorithm has a good effect of hiding and anti-cutting.
