This paper investigates possibilities to develop adaptive steganographic algorithms in general and especially for images as possible cover data. We exploit dithering as a means to gain image information that can be used by adaptive steganographic algorithms. First, we point out general possibilities for using this process for steganography and discuss advantages and drawbacks. Since the original dither criteria is not sufficient for steganography, we modify it and develop further algorithms. Considerable tests confirm the improvements of the extensions. Finally, we point out possibilities for further research.
