Anti-forensic steganography method based on randomization

Information hiding is a technique that embeds secret information into digital contents such as images, audios, movies, documents, etc. This work presents an anti-forensic steganography method that can embed and extract messages from images, which uses the same principle of LSB. The proposed model co...
