About applications of steganography ... (1)

今天早上在研讀 Hany Farid 在2001年發表的技術報告 "Detecting Steganographic Messages in Digital Images", 報告中提到了有關 steganography 的應用, 包括:
1. unobtrusive military and intelligence communication
2. covert criminal communication
3. protection of civilian speech against repressive governments.

Other applications include unobtrusive military and intelligence communication, covert criminal communication, and the protection of civilian speech against repressive governments. Along with new and improved techniques for hiding information will come techniques for detecting (and possibly removing) such information.

Niels Provos & Peter HoneyMand 在 2001 年的技術報告 "Detecting Steganographic Content on the Internet" 的 Abstract 中也提到了 covert criminal communication:

Steganography is used to hide the occurrence of communication. Recent suggestions in US newspapers indicate that terrorists use steganography to communicate in secret with their accomplices. In particular, images on the Internet were mentioned as communication medium. While the newspaper articles sounded very dire, none substantiated these rumors.
