摘要：
Based on exact histogram specification, this paper investigates the use of image histograms to hide information and proposes a new digital steganography scheme. The image is partitioned into blocks, and the data bits are embedded into the sub-histograms. The scheme uses the sub-histograms of image and keeps the original image histogram. With the new scheme we could greatly increase the payload of hidden information. The keys are introduced so that the security of the steganography system is greatly improved. Our steganography scheme is both visually and statistically imperceptible.
