Secure Data Transmission by Using Video Steganography
Abstract
It is very essential to transmit important data like banking and military information in a secure manner. Video Steganography is the process of hiding some secret information inside a video. The addition of this information to the video is not recognizable by the human eye as the change of a pixel color is negligible. With the development of the technology, people have tend to figure out methods which are not only capable in hiding a message, but also capable of hiding the existence of a message. Steganography was introduced as a result of such research work. The proposed technique applies combination of insertion of metadata and blowfish encryption to embed the information into mp4 video files. The proposed method will hide secret information at random path of video metadata. The secret message will be encrypted using blowfish before hiding it into video metadata. When steganographed by this method, the probability of finding the hidden information by an attacker is lesser when compared to the normal method of hiding information frame-by-frame in a sequential manner. It also reduces the computational time taken for the extraction process and can hide huge amount of payload without effecting the steganography criteria.

Submission of an original manuscript to the Journal of Computing Technologies and Creative Content (JTeC) will be taken to mean that it represents original work not previoussly published, that it is not being considered elsewhere for publication. All submitted articles that are published by JTeC cannot be published anywhere by the authors unless with the permission by JTeC Editors. JTeC reserves the right to the publications of the articles it published, and reserves the right to reuse the articles elsewhere for academic purposes, while still retaining the names of the original authors with the original articles.
JTeC takes the stance that the publication of scholarly research is meant to disseminate knowledge and in a not-for-profit regime, benefits neither publisher nor author financially. It sees itself as having obligation to its author and to society to make content available online now that the technology allows for such possibility.
