Abstract

Abstract: A digital watermarking algorithm based on two verdict mechanism is presented.The algorithm uses grouping shift shuffling algorithm to shuffle the watermarking，and then codes watermarking with structured coding.The carrier image is grouped to embed the whole watermarking copy dispersedly.In the extracted phase，the mechanism combining CRC coding verdict and majority verdict is offered.The experimental results show that，the algorithm has good robustness，and it can resist some familiar attacks effectively.

Key words: digital watermarking, image grouping, cyclic redundancy check coding verdict, majority verdict

摘要： 提出了一种基于双判决机制的数字水印算法。该算法利用分组移位算法进行水印置乱，并对水印信息循环编码，将载体图像进行分片以分散地嵌入多个完整水印拷贝，在水印提取阶段利用循环冗余译码判决和大数判决相结合的机制。实验结果证明，该算法具有较好的鲁棒性，能够抵抗常规图像处理。
