An Anti-Cutting Watermarking Algorithm Based on Matrix Multiplication Secret Sharing Scheme

摘要

A digital watermarking algorithm based on the matrix multiplication secret sharing scheme is proposed. It partitions the field of the image into n shares, and also partitions the watermark into n shares correspondingly. After the original image is divided, the digital watermark is embedded into the law 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.
