Hiding data in images using steganography techniques with compression algorithms
Autor: Osama F. Abdel Wahab, Hamdy M. Kelash, Hesham F. A. Hamed, Hanafy M. Ali, Ashraf A. M. Khalaf, Aziza I. Hussein
Steganography is the science and art of secret communication between two sides that attempt to hide the content of the message. It is the science of embedding information into the cover image without causing a loss in the cover image after embedding.
