%0 Journal Article %T IMAGE BLOCK-BASED STEGANOGRAPHY AND EN-CRYPTION SYSTEM FOR BUSINESS APPLICATIONS %A Dr. T.V. Ananthan %A R. Mohan Lakshmanan %J International Journal of Advanced Technology & Engineering Research %D 2012 %I %X In this modern era, communication between peers need secrecy of user data and ensuring the implementation of ge-nuine transactions is at the expense of providing reliability. In this paper, we have proposed a steganographic technique to provide security for user accounts through encryption and image bock based steganography. Encryption of user data and hiding it in a cover image using Image blocks to gener-ate a undetectable stego image will provide privacy. Because the attackers cannot identify the secret message hidden in-side the cover image with random block size to generate a stego image ensure legitimacy in business process. %K Steganography %K Encryption %K Network Se-curity. %U http://www.ijater.com/Files/IJATER_03_12.pdf
