Defeating Steganography
*Because of steganographic systems’ invasive nature, they leave detectable traces in a cover-medium's characteristics
*This allows an eavesdropper to detect media that has been modified, revealing that secret communication is taking place
*The integrity of the information is not degraded, however it’s hidden nature is revealed, thus defeating the main purpose of steganography
•Steganographic systems inherently leave detectable traces in a cover-medium’s characteristics, potentially allowing an attacker to detect it.
•This detection reveals that covert communication is taking place, thus defeating the main goal of steganography.
