This chapter explores the use of steganography on digital files and produces an enhanced technique that addresses the major vulnerabilities that make algorithms less reliable in securing data. Through a review of historical techniques in the field, the study identifies weaknesses in the algorithms to improve security and increase capacity using different techniques. One of the approaches proposed in this study involves a distributed method, which is simple, clear, low-cost, and agile. The study also analyses data manipulation and embedding processes in different files and for different purposes, such as vulnerabilities or placeholders exploited by criminals distributing viruses over the internet using Steganography. The results of the study can help forensic analysts identify secret content and raise awareness about protecting against eavesdropping data on devices. The study proposes a new scheme to improve Steganography called DSoBMP, together with guideline materials that have been published in four international peer-reviewed journals, including Springer and used as a stepping stone to collaborate in a worldwide book publication.

“…As other image formats, this reads as a continuous data stream pixel-based file, and it has support for transparency, animation features. Allowing 8-bit colour indexing only, which is in practice 256 distinct shades compared to the 16.777.216 possibilities, it has limitations [11]. As per its limitations, the capacity for hiding data is significantly smaller than the BMP format.…”

The advance of Big Data and Internet growth has driven the need for more abundant storage to hold and share data. People are sending more messages to one another and paying attention to the aspects of privacy and security as opposed to previous decades. One of the types of files that are widely shared and instantaneous available over the web are images. They can become available as soon as a shot is taken and keep this closely related to the owner; it is not easy. It has been proposed here to use Steganography to embed information of the author, image description, license of usage and any other secrete information related to it. Thinking of this, an analysis of the best file types, considering capacity, detectability, and distortion was necessary to determine the best solution to tackle current algorithm weaknesses. The performance of BMP, GIF, and JPEG initialises the process of addressing current weaknesses of Steganographic algorithms. The main weaknesses are capacity, detectability and distortion to secure copyright images. Distributed Steganography technique also plays a crucial part in this experiment. It enhances all the file formats analysed. It provided better capacity and less detectability and distortion, especially with BMP. BMP has found to be the better image file format. The unique combination of Distributed Steganography and the use of the best file format approach to address the weaknesses of previous algorithms, especially increasing the capacity. It will undoubtedly be beneficial for the day to day user, social media creators and artists looking to protect their work with copyright.

“…Correspondingly, the rival destroys the storage channel through data rewriting or normalization [13], [18]. For VoIP and other applications, the packet transmission frequency is high, and the covert channel based on storage content is also of high performance [19], [20]. Combined with steganography and other data embedding methods, the CSC also has good effect on video and multimedia applications [20], [21] Different from the CSC, the covert timing channel (CTC) is designed on fine tuning of the characteristics of packet transmission and does not change the data content.…”
