New security approach-based Steganography and Cryptography by modified AES algorithm

Abstract

The transmission of information through any channel of correspondence needs solid encryption procedures with the end goal of information security. The computerized watermarking assumes a significant part in inserting data into an advanced picture signal, for the check and character of its proprietors. In discrete wavelet change, "investigation channel bank" can be utilized for dissecting picture signals by going through. The channel bank comprises high and low pass channels at every deterioration stage. In this paper, a technique to consolidate steganography (Least Significant Method-LSM) and cryptography Advanced Encryption Standard (AES) is thought to give a safer method to information transmission through any unstable or public organizations. Prior to inserting the content in the picture, the text is scrambled utilizing AES calculation. Utilizing least significant bit (LSB) strategy, encoded the text installed in low-low (LL) subband wavelet decayed of a picture. Converse wavelet changes applied will lead to the output picture is communicated to the recipient. Presently at the collector's end, the picture changed utilizing wavelet and encoded text will be extricated by utilizing the LSB technique. This paper shows how AES calculation is utilized in the decoding of the outcome.
