Steganography Enhancement by Combining Text and Image through Wavelet Technique

Abstract

rapidly proliferated information and evolution of digital technologies by Information hiding in multimedia data has improved the ease of access to digital information enabling reliable, faster and efficient storage, transfer and processing of digital data and leads to the consequence of making the illegal production and redistribution of digital media easy and undetectable. Hence, it poses a novel challenges for researchers. In this paper we present a novel integration of an incorporating text and image steganography to find a solution for enhancing security and protecting data. We proposed an enhancement of steganography algorithm which involves the scheme of discrete wavelet transformation combining text and image by secretly embed encrypted secrete message text data (cipher text) ortext image in the content of a digital image. The system based on levels of encryption and decryption methods performed to enhance the security of the system. Here first generate secrete message text (cipher text) or text image, and then processing deals with embedding and extracting Steganography algorithms. Finally the process deals with extraction of the hiddensecrete message. The experimental result shows a high level of efficiency and robustness of the proposed system.
