Description:
In this paper, we propose a new theoretical framework for the data-hiding problem of digital and printed textdocuments. We explain how this problem can be seen as an instance of the well-known Gelfand-Pinsker problem.The main idea for this interpretation is to consider a text character as a data structure consisting of multiplequantifiable features such as shape, position, orientation, size, color, etc.
