    • Abstract:
      The works devoted to development of new steganographic algorithm that worked in spatial domain of cover-image. Proposed algorithm is robust to noise such as Gaussian, Poisson and Speckle. Proposed algorithm enforces reliability perception of stegomessage, and is a polynomial of degree 2. It is shown that the stability characteristics of the algorithm (normalized correlation coefficient for embedded information) does not depend on the type of noise and is determined only by the disturbing effect, which is evaluated in the standard way with a peak signal-to-noise ratio. Characteristics of the algorithm does not depend on the image format. Recommendations on the application of the algorithm are given. [ABSTRACT FROM AUTHOR]
