Running compression algorithms in the encrypted domain: a case-study on the homomorphic execution of RLE
FHE RLE
2017/5/11
This paper is devoted to the study of the problem of running compression algorithms in the encrypted domain, using a (somewhat) Fully Homomorphic Encryption (FHE) scheme. We do so with a particular fo...
基于RLE编码定位的数字水印算法
小波变换 二值水印 几何攻击
2009/7/21
提出了一种二值水印嵌入方案。对水印图像进行游程编码，对载体图像进行离散小波变换，选择最高级细节子带中最大系数为嵌入目标，由密钥K1将水印图像的游程编码拆分成两部分，密钥K2和水印图像的RLE码值共同确定嵌入位置。检测时，根据游程码值和小波系数变化幅度两个原则检测水印信息。实验结果表明：该方案不仅具有很好的不可感知性，而且对常规图像处理和几何攻击均具有较好的鲁棒性。
