Multi-bit watermarking in the data stream of JPEG2000 using minimum error embedding technique

In this paper, we use a novel multi-bit minimum error replacement with flexible bit location (multi-bit MER_FBL) embedding method to perform watermarking for embedding multi-bit logo images into the JPEG2000 data stream. The novel multi-bit MER_FBL embedding method embeds multi-bit logo data into the JPEG2000 data stream after quantizing the DWT coefficients. Because the proposed embedding method has the feature of flexible bit location which enhances robustness as possible as the embedding locations closing to the MSBs of cover data. We therefore developed a multi-bit MER_FBL embedding scheme based on the proposed method and then used it to build a novel multi-bit, invisible, and blind watermarking scheme in the quantized DWT domain to evaluate its performances. Simulation results show that the proposed multi-bit MER_FBL embedding method achieves high embedding capacity, good embedding quality, and high robustness for watermarking application. Comparisons shows that our work has better performance than those of the other previous works.
