The 2D-steganography method in the spatial-frequency area
In this article is elaborated the 2D-steganography method in the spatial-frequency area on the basis of spectral components updating. We have fulfilled probing of quality of a method by means of two algorithms: algorithm of embedding of the stego-message in the least significant bit (LSB) of the stego-container and the algorithm of two least significant bits (2LSB) analysis of the stego-container and modification of the LSB of its countings.
