Abstract

A chosen plaintext steganalysis algorithm is described to isolate the corrupted bits in an image tampered with Hide4PGP V 2.0. The method is developed from the notion of representation of two dimensional image data in terms of a linear bit stream consisting of a set of basic building blocks. Its performance for message extraction is demonstrated on different 24 bit BMP images.
