Hiding Information in Region-based Wet Images
In most data-hiding schemes, the area of interest in the cover image cannot be protected from being modified. In this paper, we propose a data-hiding scheme in which the changeable and unchangeable pixels can be specified by the data-hider. To reduce the size of extra information, the location map used to depict the location information of changeable and unchangeable pixels is compressed by Run Length Coding (RLC) or by Huffman coding. Therefore, only a little additional information, a private key, is needed to depict the changeable pixels in which the Run Length code or the Huffman code is embedded. The experimental results show that our proposed scheme can efficiently embed and successfully extract the secret information.
