COPYRIGHT PROTECTION FOR IMAGES IN DIGITAL MUSEUMS
摘要
Abstract
With the rising of digital museums, people pay more attention to copyright protection of images in digital museums. At first digital watermarking and digital museums are introduced; then the copyright protection problem for images in digital museum with digital watermarking technology is discussed; then a novel SVD-based blind digital image watermarking algorithm is proposed. The algorithm pre-processes a watermark by Arnold chaos map, then according to the watermark's size, divide the original image into a number of child-blocks, each of which is decomposed with matrix SVD method. The algorithm realizes watermark embedding by comparing adjacent image blocks' largest SVD values. Experiment results show that the algorithm is strongly robust against JPEG lossy-compression, cropping, noising or other attacks.关键词
