An Efficient Security Approach Using PGE and Parity Coding

Information Attacks are showing the weaknesses of Information security due to the rapid growth of theglobalisation. The main aim of these attacks is to retrieve the information by illegal that shows the faultsin the security services. In this paper, we introduce a novel secure steganographic approach for defendingagainst these information attacks. In this approach, instead of original message an encrypted message byPrime Number and Gray Code Encryption (PGE) Algorithm is hidden into an Image (Stego Image) usinga new approach named Linear Block parity coding (LBP) which provides more security than conventionalapproaches. The major strength of this paper is steganalysis has discussed. The computational complexityis comparatively low with other methods since our feature vector space is limited interference is notobjectionable.
