Abstract
Westfeld [1] analyzed a sequential LSB embedding steganography effectively through the χ 2–statistical test which measures the frequencies of PoVs(pairs of values). Fridrich [2] also proposed another statistical analysis, so-called RS steganalysis by which the embedding message rate can be estimated. This method is based on the partition of pixels as three groups ; Regular, Singular, Unusable groups. In this paper, we propose a new steganographic scheme which preserves the above two statistics. The proposed scheme embeds the secret message in the innocent image by randomly adding one to real pixel value or subtracting one from it, then adjusts the statistical measures to equal those of the original image.
