ANALYSIS OF THE RESISTANCE OF STEGANOALGORITHMS TO GEOMETRIC ATTACKS AND COMPRESSION

DOI: 10.31673/2409-7292.2025.020965

Abstract

The analysis of the stability of steganographic methods of hiding in the spatial domain to attacks common in open and
closed channels, such as geometric transformations and compression, was carried out. The impact of these attacks on the stability
of the steganochannel operation was assessed and methods for increasing the stability to such attacks were proposed. Various
types of attacks based on affine transformations and their impact on the quality of information hiding were investigated.
Attention was focused on preserving the integrity of the message during such attacks.
The study evaluates the possibility of using different types of messages and the impact of coding with repetition on the
stability of the steganosystem. A method for assessing the stability of attacks based on the bit error method was developed and
simulated, which was modified for analysis at the byte level in order to apply the results to different types of containers and
support streaming data.
The importance of the absence of the influence of the order of pixel placement when embedding a message is noted,
which allows minimizing the impact of geometric transformations on the embedded message. The resistance of the color space
modification algorithm to attacks is higher than that of the LSB method by 14-98%. LSB has a 10% higher resistance only to a
minor scaling attack. However, this difference does not allow us to call it practically suitable for use.
The influence of image resolution on the amount of embedded information in each of the methods is analyzed. Promising
directions for further research are analyzed by introducing block coding and using effective error correction methods and using
alternative container properties for embedding.
Keywords: steganography, geometric attacks, affine transformations, color space.
