摘　　要：根据Ching-Yung Lin和Shih-Fu Chang提出的JPEG压缩过程中的两个不变性原理,本文设计了一种半脆弱水印算法,该算法满足半脆弱水印的要求。以图像自身的特征作为水印嵌入到图像中,不需要原始水印从而达到可盲检测的目的。Based on the two invariance principles of JPEG compression that Ching-Yung Lin and Shih- Fu Chang proposed, A semi-fragile watermarking, algorithm is designed in this paper, which meets the demand of semi-fragile watermarking. Our scheme does not use primeval watermarking but adopt images embedfrom the traits of themselves, which achieves the blind detection.
