Abstract

In order to solve the problem of embedding capacity, imperceptibility, real-time and tampering localization in JPEG image watermarking algorithm, this paper proposed a JPEG watermarking algorithm based on entropy coding. Firstly, the algorithm located the process of JPEG entropy coding to embed the watermarking, which could avoid the forward and reverse quantization operations and ensured that during embedding image changes was small and had good real-time performance. Se-condly, according to the principle that some bits in the entropy coding process do not participate in the Huffman coding, the algorithm chose appropriate coefficient to embed watermark. This algorithm embedded watermarking information into the least significant bits of these coefficients to avoid the coding error caused by the modification of the Huffman coding coefficient, which should further enhance the imperceptibility of the algorithm. Experimental results show that the algorithm not only has a large embedded capacity and good imperceptibility, but also has high fragility and can accurately locate malicious tampering.
