摘要

Steganography is an important branch of information hiding, which is an effective way to solve the problem of communication security. Steganography can hide specific secret information in some kind of public information, such as images, documents, audio and video, without any suspicion. Joint Photographic Experts Group (JPEG) compressed image is the most widely used image format on the Internet. Recently, a series of JPEG image steganographic algorithms have been proposed. However, the existing JPEG steganography usually designs the cost function based on the statistical distribution in the DCT domain. In this paper, with the help of a Microscope, which can enhance the JPEG images in the spatial domain and highlight the texture regions, we design the steganographic cost function based on the statistical distribution of JPEG images in spatial domain and work out a JPEG image steganography with high security performance. Experimental results demonstrate that the proposed designing strategy is a practical approach to against several existing state-of-the-art steganalytic tools.
