Abstract: | In the digital era, multimedia content are shared for every second in newlinethe form of 3D data. The 3D data are highly used in the industries and this newlinefaces plenty of issues in maintaining the privacy of document. Sharing of newlinedocument leads to illegal copying of data and that leads unintended user to newlinemisuse the document. 3D watermarking is a technique that overcomes this newlineproblem by hiding the secret information in the 3D data and thereby proving newlineone s ownership. The capacity of embedding should be high so that entire newlinesecret information can be hidden in the 3D data. In addition, the algorithm newlineshould provide robustness such that the secret image should be able to detect newlineafter a certain level of malicious attack without having the original 3D model. newlineThis research work proposes four novel blind robust algorithms newlinebased on spatial domain watermarking. The four proposed algorithms are newlineLeast Significant Digit Substitution algorithm, Randomized Least Significant newlineDigit Substitution algorithm, LBG Modified Randomized Least Digit newlineSubstitution algorithm and Hypothesis based Vertex Shifting algorithm. newline newline |
