A Detection Study of an NRL Steganographic Method
Ira S. Moskowitz, Neil F. Johnson · 2002
In this report we analyze in detail a method of image steganography developed by NRL. Our conclusion is that this method of steganography is undetectable by current pragmatic statistical stego detection techniques, primarily because it alters a very small number of pixels. The small size of the embedded message is the key to the lack of detection, provided that a non-anomalous cover image is used.
