Abstract: “Image-based steganography is the practice of embedding secret information into digital images with the intention to communicate the secret information. Embedding large sizes of secret information into digital images is one of the problems that image-based steganography encounters. The distortion of digital image increases with larger capacity, meaning that both are positively correlated. The latter makes image-based steganography fingerprints perceptually and statistically visible. In this paper, we propose a new spatial-domain steganographic scheme based on Bit-Plane Complexity Segmentation (BPCS). Experimental results reveals that the proposed algorithm offers better embedding performance compared with prior BPCS-based algorithms in terms of image quality and capacity.”
