摘要：
In order to solve the security problem of the multimedia in the communication process, steganography plays a vital role. In this paper, the DCT domain of digital image steganogyaphy is to study the impact of image quality with different embedding positions, the secret information in the DCT domain of an image, different carrier images and the amount of information. Studies show that: embedding the information in the low frequency part of the image, selecting the image with the rich distribution pixel value, is conducive to improve the steganography effects of the information in the image, enhance the concealment of the secret information.
