Advance 3-bit LSB based data hiding using steganography

Abstract

Nowadays, security plays a main role for data hiding and makes it confidential from unauthorized access. So steganography and cryptography techniques are used for data security. In this paper, 3-bit least significant bits technique is used for embedding secrete image into the cover image. The resultant image after embedding the secrete image into cover image is a “Stego Image.” Using Vvisual Cryptography, transferring the stego image over the wireless channel or Internet becomes more securable because it divides the encrypted message and transfers it into two shares based threshold. In this paper, ECC algorithm is used to kept data more secure and secrete which makes very hard to get secrete message even if the secrete message is disclose. These proposed systems will work on large size of image and result with high performance and accuracy with high PSNR for color image.
