Watermarking Algorithm with Resistance to JPEG Lossy Compressing and Images Uniting
抗JPEG压缩和图像合并的水印算法

It is the first time to expound the watermark application under images uniting in this paper. With the affecting of JPEG lossy compressing, the universal solving scheme is proposed, and the corresponding security analysis is made. In the direction of this scheme, a watermark algorithm is proposed which can resist the JPEG lossy compressing and images uniting question. The test results prove its both characters.
