Steganographic Message Transformation with the Partial Antidisturbance Property

In this article we present a new method of steganographic transformation of a binary message, which allows to embed secret data with minimal statistical distortion of the original message. The constructed algorithm should be applied before steganographic embedding message in a container. The transformation renders inefficient a number of stegoanalysis methods based on the statistical deviation analysis in message, extracted from an empty and filled container. When applying this algorithm, the stegoanalyst cannot properly extract from container up to 32% message bits, and accordingly, realize some stegoanalysis methods. According to the new method the message from empty container are transformated and after embedded again at the same container. The size of secret data is 19% of the total container capacity. In this paper various stegoanalysis methods for text data are considered, it was demonstrated their inefficiency after application of the new method.
