A High Capacity Steganographic Method Based on Quantization Table Modification and F5 Algorithm

This paper presents a steganographic method based on quantization table modification and the F5 algorithm. This method has a larger embedded secret message capacity and improves the embedding strategy to avoid "shrinkage" due to the use of the F5 algorithm. The experimental results show that, in comparison with the F5 algorithm and other methods, the proposed method has a higher steganographic capacity and an improved embedding efficiency. In terms of the structural similarity as well as PSNR for assessing image quality, the stego-image has better image quality and the proposed method has better anti-attack capability.
