Reversible Steganographic System for the Transmission of Personal Medical Data

This paper discusses the development and analysis of a steganography method for reversible data hiding in raster images. This method is intended for use in medical images for the purpose of storing personal data of patients. The stego-containers created with its help preserve some statistical characteristics of the image by dividing it into coherent regions by the “forest fire” method and collecting statistics of low-order bits, which allows to form a sequence with a given probability distribution. To ensure the reversibility of the steganographic system, the INP interpolation method is used. The developed system has an embedding capacity of 0.6 bits/pixel. The paper also presents the results of stegoanalysis on the basis of BOSS _ vl.01 images processed by this method, as well as the data of visual analysis of stego-containers and evaluation of their properties by visual distortion criteria.
