In this paper the focus is on maintaining secrecy between two communication parties using steganography and cryptography technique. In this system cover data (Image) and secret data (Image / Text) by using DWT (Discrete wavelet transform) then secret data is first embedded in to cover image by using LSB (Least Significant Bits) algorithm and then resulted embedded image by using IDWT (Inverse Discrete Wavelets Transform) algorithm to form Stego-image. Then DWT (Discrete Wavelets Transform) algorithm on the stego image then resulted image by using LSB extraction to form recovered secret data. For the analysis of the proposed method MSE, RMSE, PSNR, Correlation and SNR was calculated for each of the cover and recovered secret data. The DWT (Discrete Wavelets Transform) algorithm is found to be better in the terms of efficiency, robustness, highly security and embedding capacity. With rapid growth of World Wide Web and advance computer network, we need security, privacy, integrity and authentication in the data communication. A steganography is art of hiding sensitive information in another cover medium. The main objective of this paper is to achieve quality and secure communication.
