For convenience, we used stego
images (a), (b), and (c) to reconstruct the secret image.
From table 3 we can see that there are a little differences between the histogram of cover and stego
Multi-level IDWT: the IDWT transform is applied to the coefficients of the stego
Repeat Steps 1-5 until all secret bits are embedded and the stego
image is produced.
Concrete announced an agreement in April whereby San Clemente, Calif.-based Stego

. The technology itself is harmless and can actually be a force for good.
Even in more usual locations (southern Wyoming, Utah, and Colorado), only a half-dozen stego

WetStone Technologies' Stego
Watch (WetStone Technologies 2004) analyzes a set of files and provides a probability about which are steganography media and the likely algorithm used for the hiding (which, in turn, provides clues as to the most likely software employed).
A common "stego
" method employs the slight distortion of a sequence of pixels, which are individual dots of color.
