Genetic Algorithm with Chaotic Fruit Fly Optimization Algorithm for Discrete Wavelet Transform based Secret Sharing Cryptography Model

Abstract

At present times, secure data transmission becomes essential to safeguard the images while communicating with other people through Internet.Image Stegnography defines the way of concealing data in an image. The image chosen for this task is referred by cover image and the image attained next to stegnography is known as stegno image. This paper presents an effective secret sharing cryptography method for secure data transmission by incorporating discrete wavelet transform (DWT) and secret sharing (SS) model. Initially, discrete wavelet transform (DWT) is employed for transforming the region. For optimal selection of the parameters involved in DWT, Genetic algorithm with Chaotic FruitFly Optimization algorithm (GACFFOA) is employed. Then, SS gets executed for lower band stegno images with highly secure process. At the same time, Visual Cryptography is applied for encrypting a secret data. A detailed experimental validation has ensured the superior features of the GACFFOA over the compared models.
