Methods and algorithms for embedding marked information with fractal properties to ensure the integrity and authenticity of raster images are considered. The features of using algebraic fractals as intermediate cover images, as well as secret keys that define places for embedding watermarks, are analyzed. Numerical examples show that the proposed methods increase the integrity and authenticity of bitmap images.
