| Abstract | A new procedure for watermarking in the 8x8 block-based DCT domain (used for JPEG compression) is proposed. The influence of JPEG quantization on watermarked coefficients and on watermark is considered. The criterion for coefficients selection is derived, providing robustness for an arbitrary quantization degree. The modified form of coefficients pdf leads to the class of modified optimal detectors. Theoretical results are illustrated on various examples. Efficiency of the proposed procedure is shown in the presence of different quantization degrees, and some other common attacks. |
