【摘要】 针对数字图像易遭受复制-移动攻击问题,提出一种精确匹配算法来检测图像是否遭到攻击.此方法不论伪造区域是被放大/润饰后与背景融为一体,还是伪造的图像是有损压缩的存储方式(如JPEG),都可以检测到伪造区域,成功率较传统方法有很大提高.更多还原

【Abstract】 An algorithm called exact match is proposed to solve the problem of copy-move attack in digital images. The method may successfully detect the forged part even when the copied area is enhanced/retouched to merge it with the background and when the forged image is saved in a lossy format, such as JPEG. The result is much more efficient than traditional methods.更多还原
