Abstract

A novel image content protection (ICP) method is proposed in this paper. To satisfy the fundamental requirement for ICP, i.e. being robust to non-content operations and sensitive to content tampers simultaneously, a pixel-level image content map (PICM) is extracted by dynamic weighted averaging. Then, a regional image content map (RICM) is derived through segmentation of PICM and its invariant moments are converted to watermarking bit stream that is embedded in the source image robustly to achieve protection of the content. Various experiments show that the hierarchical content representation, i.e. P-RICM, and its invariant moments have excellent performance in ICP, and our method meets the fundamental criterion well.
