Abstract :
Steganography is the art and science of hiding the fact that communication is taking place. Steganographic systems can hide messages inside of images or other digital objects. To a casual observer inspecting these images, the messages are invisible. The security of a classical steganographic system relies on the secrecy of the encoding system. Once the encoding system is known, the steganographic system is defeated. However, modern steganography should be detectable only if secret information is known, namely, asecret key. Because of their invasive nature, steganographic systems leave detectable traces within a medium´s characteristics. This allows an eavesdropper to detect modified media, revealing that secret communication is taking place. Although the secret content is not exposed, its existence is revealed, which defeats the mainpurpose of steganography. This work has as purpose to expand the field of applicability of the steganography from the classical informatics to the quantum one.
