This paper presents two steganographic methods for JPEG2000 still images which preserve histograms of discrete wavelet transform (DWT) coefficients. The first one is a histogram quasi- preserving method using quantization index modulation (QIM) with a dead zone in DWT domain. The second one is a histogram preserving method based on histogram matching using two quantizers with a dead zone. Comparing with a conventional JPEG2000 steganography, the two methods show better histogram preservation. The proposed methods are promising candidates for secure JPEG2000 steganography against histogram-based attack.
