Abstract: For secure data hiding and transmission over the wireless network Image steganography is a best technique . The best way used to propose system is achieved by Least Significant Bit (LSB) based steganography using Genetic Algorithm (GA) along with Visual Cryptography (VC). It initiates with Original message which is converted into cipher text by using secret key and then hidden into the LSB of original image. For enhancing the security during transmission Genetic Algorithm and Visual Cryptography has been used. Genetic Algorithm basic function is to modify the pixel location of stego image and the detection of this message is complicated. Encryption of the visual information is carried out by Visual Cryptography . It breaks the image into two shares based on a threshold. The consummation of the proposed system is experimented by performing steganalysis and conducting benchmarking test for analyzing the parameters like Mean Squared Error (MSE) and Peak Signal to Noise Ratio (PSNR). This paper is based to design the enhanced secure algorithm which uses both steganography using Genetic Algorithm and Visual Cryptography to ensure improved security and reliability.
