A new region of interest (ROI)-based watermarking method for JPEG 2000 is presented. The watermark is embedded into the host image based on the characteristics of the ROI to protect rights to the images. This scheme integrates the watermarking process with JPEG 2000 compression procedures. Experimental results have demonstrated that the proposed watermark technique successfully survives JPEG 2000 compression, progressive transmission, and principal attacks.

“…Based on our previous work [16], the aforementioned watermarking approach, integrated to lossy wavelet-based coding scheme is promising. However, many of the resulting watermarked-decompressed images still have unacceptable fidelity because of the regular partitioning of scalar quantization, which is not efficient when high visual quality reconstruction is required.…”

“…In contrast, there has been only limited research focused on the issue of re-quantization, among which JPEG2000 compression is a typical one. As cited in [16], at mean or high bitrates, the watermark robustness, against JPEG2000 compression attacks, is expensively paid by noticeable image quality degradation.…”

In recent years it has been recognized that embedding information in wavelet transform domain leads to more robust blind watermarks. A major difficulty, however, in watermarking in transform domain lies in the fact that constraints on the allowable distortion at any pixel are specified in the spatial domain. In order to insert an invisible watermark, the current trend has been to model the Human Visual System and specify a masking function which yields the allowable distortion. However, this method is highly suboptimal since it leads to irreversible losses at the embedding stage because the watermark is being adjusted in the spatial domain with no care for the consequences in the transform domain. The central contribution of this work is the proposal of integrated wavelet-based non-linear scaling QIM (NLS-QIM) watermark design to reduce fidelity problem. We consider the watermarking process in conjunction with lossy JPEG2000 compression engine. Experimental results have shown that the proposed watermarking strategy exhibits high robustness to compression attacks with respect to the reconstruction quality. Moreover, it provides a significant capacity improvement compared to other hybrid watermarking coding methods in the literature.
