An Efficient Security Approach Using PGE and Parity Coding
Ch. Rupa · International Journal of Distributed and Parallel systems · 2012
Information Attacks are showing the weaknesses of Information security due to the rapid growth of the globalisation.The main aim of these attacks is to retrieve the information by illegal that shows the faults in the security services.In this paper, we introduce a novel secure steganographic approach for defending against these information attacks.In this approach, instead of original message an encrypted message by Prime Number and Gray Code Encryption (PGE) Algorithm is hidden into an Image (Stego Image) using a new approach named Linear Block parity coding (LBP) which provides more security than conventional approaches.The major strength of this paper is steganalysis has discussed.The computational complexity is comparatively low with other methods since our feature vector space is limited interference is not objectionable.
