Popis:	Steganography is a method of hiding secret information into an innocent looking container. Although a large number of steganography techniques have been proposed, there is a constant need for new variants because they have a relatively short lifespan, being defeated by steganalysis techniques. This article explores the possibilities of eliminating the main drawback of LSB steganography: weakness. The problem is solved by rearranging the image pixels and by applying a compensation technique that preserves their statistical properties. The proposed method contains an encryption block that adds an extra layer of security to the hidden data
