An Efficient Steganography using ABC Optimization and Image ScramblingScheme

Abstract

:With the evolution of Internet Technology, the need for the security of information during its transmission has also increased rapidly. Steganography plays a prominent role in the field of data hiding and providing a means for secret communication. Steganography basically refers to the process of secretly hiding messages into a cover medium in a way that only the receiver can suspect its existence. In this, the data is hidden behind the cover image. The data is hidden character wise behind the pixels of the image. The various algorithms or techniques used for steganography are LSB-Hash, RSA Encryption, and Decryption. In this project, we use DES Encryption to increase the security level, and DWT to preserve the original quality of the cover image, while also keeping the original image intact after extraction. The usage of ABC Optimization increases the embedding capacity and gives improved PSNR and MSE values. Along with this scrambling algorithm to increase the security level of transmission
