Design of Image Steganography using M-BAT Optimization

Abstract

This paper devotes itself to the study of secret message delivery using the cover image and introduces a novel steganography technique based on bat algorithm. To maintain the same quality even after extraction of the image at the receiving end of the system, we used a data encryption standard approach integrated with wavelet transform for preserving high security. Also to increase the embed capacity modified BAT technique is used that results in high PSNR and low MSE values. With the help of modifications to exploitation, swarm initialization and Torus gives rise to (M-BAT) for fast convergence rate. All the simulations are carried with Matlab 2017a and its evaluation parameters are related with other traditional techniques.
