Computing Experiment of LSB Detectors Set Reduction with Definite Reliability for 1-to-1 Pattern

The technology that allows to decreasing the set of steganalytical methods that determine the payload value in the image spatial domain using quantitative detectors of Least Significant Bits steganography. It consists of mathematical model, an algorithm for implementing the model and computer program. The mathematical apparatus of regression analysis is used. The results of the development and testing of the technique for reducing the set of steganalytical methods taking into account the accuracy and reliability to the diminution of the computational complexity of steganalytical expertise are presented.
