Robust watermarking procedure based on JPEG discrete cosine transform image compression


bstract. A new procedure for watermarking in the 8 8 blockased discrete cosine transform (DCT) domain (used for JPEG ompression) is proposed. The influence of JPEG quantization on atermarked coefficients and on watermark is considered. The crierion for coefficients selection is derived, providing robustness for n arbitrary quantization degree. The modified… (More)
