In addition, VC-based watermarking may be used to robustify recognition of an extracted watermark from images which have been subjected to attacks [2,3]. For example, in the approach shown in Fig. 1, instead of embedding a binary logo directly to the host image, a VC-based watermarking scheme first encrypts the binary logo into two noise-like binary shares. One of the two generated shares can be viewed as a private watermark share and is kept by the owner. The other share represents a public watermark share and is being embedded to the host image using a conventional watermarking technique which operates either in the spatial or frequency domain of the host image [2,3].},
