【摘要】 从计算机图形学中纹理技术的 MIP图方法出发 ,对数字图像信息隐藏的抗攻击方法进行了研究 ,其目的是对具有一定保护价值的数字图像进行保密传输和安全存储 .文中采用计算机图形学中的 MIP图方法来增强数字水印的鲁棒性 ,该方法的核心是通过将原始图像信息和需要隐藏的图像信息按照 MIP图的方法进行存储 ,这使得需要隐藏的信息不再隐藏在原始图像中 .当需要对隐藏信息进行恢复时 ,即使该原始图像受到了非常强的攻击 ,也可以按照 MIP图对数字图像的恢复方法 ,保证隐藏信息的恢复 .实验证明 ,这种方法可以抵挡在数字图像信息隐藏领域常见的攻击 ,在一定条件下 ,这种方法是安全可行的 .更多还原

【Abstract】 Anti-attack method based on mipmapping is discussed to improve the security of transferring and storing of digital image. MIP comes from the Latin “multum in parvo”, meaning “many things in a small place”. The kernel of this method is that hiding digital image and compressed original digital image are inserted into the appointed position in MIP, while hiding digital image is no longer hidden in the original public image. When the hiding digital image needs to be reconstructed, we can surely restore it even if the public image has been destroyed strongly. Our experimental results demonstrate the algorithm is reliable and feasible in certain conditions.更多还原
