Description
Summary:碩士 === 國立高雄第一科技大學 === 電腦與通訊工程研究所 === 101 === In this thesis, the digital image data hiding schemes based on two-dimensional (2-D) squares and three-dimensional (3-D) cubes are presented. First, the approaches to construct the 2-D squares and 3-D cubes are described including magic squares and magic cubes, toral automorphism based squares and cubes, and random permutation squares and cubes. Then, the embedding and extraction methods of gray-level image data hiding scheme using 4x4 squares and 4x4x4 cubes are presented. Next, the proposed method is extended to develop the data hiding scheme of digital color image in the RGB color space. Finally, several experimental results are demonstrated to show the effectiveness of the proposed data hiding schemes by considering the trade-off among image distortion, hiding capacity and resistance of attacks.
