Developing a Video Steganography Toolkit
This work addresses the need for practical video steganography tools, but it appears incremental as it focuses on reviewing and describing issues rather than introducing new methods.
The paper tackles the problem of information hiding in video streams, which is less explored compared to image and audio steganography, by reviewing the state of the art and describing key issues in developing a practical system, but it does not report specific results or numbers.
Although techniques for separate image and audio steganography are widely known, relatively little has been described concerning the hiding of information within video streams ("video steganography"). In this paper we review the current state of the art in this field, and describe the key issues we have encountered in developing a practical video steganography system.
