| 摘 要： | 在数字水印的买卖交易应用中,卖方在交易前把买方的数字指纹和卖方的版权水印同时嵌入作品中.一旦作品受到侵犯,数字指纹和版权水印可以用来鉴别谁拥有合法版权,谁是非法转售者.提出了一种基于离散小波变换(DWT)的鲁棒买卖交易水印算法,该算法能够把数字指纹和版权水印同时嵌入一幅图像中.该算法有三个优点:在提取水印时不需要原始作品;水印嵌入后图像仍保持良好的不可感知性;具有抵抗多种攻击的鲁棒性.

| Abstract: | In a buyer-seller watermarking application,a seller should embed a buyer's fingerprinting and seller's watermark into the work before the sale of a work to a buyer.If the work is violated,the fingerprinting and watermark can be extracted to identify who holds the legal copyright of the work and trace the illegal reseller.A robust buyer-seller watermarking scheme is proposed based on discrete wavelet transform(DWT)which embeds the buyer's fingerprinting and seller's watermark into an image.The proposed schem... |
