Modification of Steganographic Algorithm Using LSB and a Set of Stegomedia

Abstract

Ambition to achieve possibility to hide digitally represented information which is coded in bit sequences into digital cover media is fulfilled through a number of steganographic algorithms, including Least Significant Bit (LSB) algorithm. A further development of those algorithms can be seen in the use of multiple cover media in the form of their sets, into which digital information is distributed by the use of multiple distribution functions (multi-carrier steganographic algorithms). This paper describes design of steganographic algorithm that is based on the use of the Least Significant Bit (LSB) and three distribution functions, which allow to distribute digital information into the set of cover media. The part of this article is describing software solution which was designed, developed and tested as the part of this research.
