An efficient high payload ±1 data embedding scheme

Embedding of confidential data in the least significant bit of an image is still an attractive method of steganography. Utilizing the full capacity of cover images by embedding one bit of data per pixel, using methods such as LSB flipping or LSB matching, usually decreases the security, making the algorithm vulnerable to steganalytic attacks. In this paper, we propose a novel efficient high payload ±1 steganographic method based on a special …
