Popis: This paper presents two JPEG steganographic methods using quantization indexmodulation (QIM) in the discrete cosine transform (DCT) domain. The two methodsapproximately preserve the histogram of quantized DCT coefficients, aiming atsecure JPEG steganography against histogram-based attacks. In comparison withF5 as a representative JPEG steganography, the proposed methods show high performancewith regard to embedding rate, PSNR of stego image, and particularlyhistogram preservation.
