A digital watermarking algorithm based on the matrix multiplication secret sharing .scheme is proposed.It partitions the field of the image into n shares, correspondingly.After the original image is divided, the digital watermark is embedded into the low frequency DCT domain and only needs part shares in the recovering course. Experimental results show that this algorithm has a good effect of hiding, anti-cutting and anti-compressing.
