Enhancing the Security of SMMWB Image Steganography Technique by using the Linked List structure (Cover Package Method)

Abstract

The rapid development of data transfer through the internet made it easier to send and receive gigabytes of data accurately. One of the most important factors of information technology and communication is the security of the information. For security purposes, the concept of steganography has been used. Steganography is a covert communication in which the existence of the message is not known to anyone other than the sender and the receiver. The secrecy is gained by hiding information in other information or carriers like audio, video, digital images etc., but digital images are the most popular carriers, that’s because a lot of reasons such as their frequency on the internet. In fact, there exists a large variety of image steganography techniques some are more complex than others and all of them have respective strong and weak points, because of these weak points this work has been proposed. This paper contains a new proposed method which can be applied on any previously proposed image steganography technique as a pre-processing step to be added before the embedding steps to make the technique achieves its goals and strengthen its weak points, this method is the Cover Package which briefly means instead of using only one cover image to hide the secret message, a lot of cover images or a package of cover images can be used.
