ABSTRACT
This paper presents an efficient JPEG steganography method based on heuristic optimization and BCH syndrome coding. The proposed heuristic optimization technique significantly decreases total distortion by inserting and removing AC coefficients 1 or -1 in the most appropriate positions. The implemented data hiding technique is based on structured BCH syndrome coding. This method achieves multiple solutions for hiding data to a block of coefficients. The proposed data hiding method chooses the best solution with minimum distortion effect. As a result, the total distortion can be significantly reduced, which results in less detectability of the steganalysis. The experiments include the steganalysis of the proposed data hiding methods. The experiment results shows that the proposed heuristic optimization significantly decreases detectability of the steganalysis. The proposed methods also outperform the existing steganography methods.

A JPEG-based statistically invisible steganography
ICIMCS '11: Proceedings of the Third International Conference on Internet Multimedia Computing and ServiceThe objective of steganography is to implement covert communication by hiding data in digital files such that there is no indication of the existence of hidden data; so an ideal steganographic system should be able to withstand all steganalysis methods--...
A steganographic method based upon JPEG and quantization table modification
Special issue: Intelligent multimedia computing and networkingIn this paper, a novel steganographic method based on joint photographic expert-group (JPEG) is proposed. The proposed method modifies the quantization table first. Next, the secret message is hidden in the cover-image with its middle-frequency of the ...
