Pre-processing for Adding Noise Steganography

This paper introduces and discusses an idea for utilizing noise introduced by scanning for steganography. In contrast to known approaches, we suggest a pre-processing step in order to reduce noise before embedding. This step shall enable us to embed by adding a noise signal without increasing local variances. The paper describes characteristic features of noise and possibilities to measure and consider them. Furthermore, we introduce a method to generate a noise signal that adheres to our simplified description. For embedding this signal, we consider the use of existing methods. Practical test results confirm the suitability of our approach, even if one must be aware of general limitations.
