High Security of Data Using Steganography with Hybrid Algorithm

With the modern technology in communication, there need some security on computer network. This security is one of the significant problem in tha data communication. Steganography is the art of hiding the message such that its presence cannot be detected. Message or encrypted message is hidden in the other carrier object before passing it through the network. In the existing system, for hiding the data only one technique is used i. e. steganography with X-box. In this paper, we will use 4 X-box technique which will hide 3 secret bit in each pixel of 24 or 32 bit cover image with hybrid algorithm i. e. AES and SHA-512. This will improve the security and PSNR value.
