Constructing Stegosystem for Raster Images on the Base of Stochastic Modulation Adjusted for Statistics of Least Significant Bits
Abstract
In the present paper we suggest the method of hiding message in the least significant bits of raster images which was complemented and improved by using well-known scheme ±1. In contrast to ±1 method, our scheme codes embedded message under rates of appearing values 0 and 1 in the least significant bits for the purpose of statistic minimum distortion peculiar to empty container. The algorithm of embedding bits in the image matrix is similar to method ±1. Steganalysis of developed algorithm is running and its advantage in comparison to primary one is demonstrated.
