System and method for hiding data reversu00ecveis robust and recovery of data in domu00ecnio space.A method including identifying at least two subsets of pixels within a block of an image; form a plurality of groups of pixels of at least two subassemblies of a pixel.Each group of pixel having at least one pixel of a first of at least two sub assemblies and at least one pixel of a second of at least two subsets; producing a plurality of values of difference, each group of pixel providing a so-called values of difference.Each value of the difference based on the differences between pixel values of the pixels in one of the groups of pixel and modify the values of the pixel of the pixels in less than all of the at least two subsets, thus building a value of bit in the block.
