ABSTRACT:

The combination of encryption and invisibility of encrypted data, it unchanged the message entirely protected against data espionage. This concept can also provide an easy means to exchange imperative messages in a message. Based on this concept, we proposed a new encryption algorithm that providing confidentiality and authentication for secure data and this data is hiding behind cover image by using proposed steganography algorithm having less cover size. Another concept we used in this that is discrete wavelet transform which is applicable on large size of secretes image data to compress. PSNR and Entropy of stego image is showing the effectiveness of proposed algorithm.
