Yet again, I find myself in the position where I am being defeated by either GCC, Makefile or library linking. This rather frustrated blog post concerns Makefile issues I have been having. I have started exploring a couple of ideas in my head, but to implement them, I ideally need more structure to the codebase rather …

Over the past week and a bit I have been battling with the problems of using a managed Java wrapper to interact with the FFmpeg (a video library). In short, all of the wrappers I have found only extend the higher-level functionality of the library – I need to interact with lower-level packet/frame data. So, to cut a …

The aim for this week was to try and develop some method of encoding information in a video - this was quite an ambitious aim to be achieved over the course of a single week. Until this point, I used a Java library called Xuggler, a wrapper for the FFmpeg C/C++ library. This tool worked well when I was experimenting …

Today's developments have been reasonably practical. I have set up a Git repository and have started work on a "Steganosaurus" which is taking the form of a Swing GUI application. So far, I have just implemented the basic Image and Audio steganography methods, which are exposed via the Tools section of this …

I have very briefly experimented with Xuggler. Xuggler is a tool that wraps the functionality of FFmpeg, and provides the ability to uncompress, modify, re-compress and transcode video. I have started developing a swing application in Java that I will use to how all of the steganography tools and techniques I develop. …

Below are the remaining summaries of the papers mentioned in my Description Stage and Papers blog post. Shanableh, T. (2012). Matrix encoding for data hiding using multilayer video coding and transcoding solutions. This paper proposes a technique for hiding data in the MPEG file format. Matrix encoding is used in this …

Below are summaries of some of the papers mentioned in my Description Stage and Papers blog post. Singh, S. & Agarwal, G. (2010). Hiding image to video: A new approach of LSB replacement. This paper describes a technique for hiding an image in a video by hiding each row of pixels in the first row of pixels of …

So far, I have completed the description stage document, which outlines the current developments in steganography and the problems and processes that this project will need to tackle. Over the past week and a bit, I have been locating papers that discuss relevant areas of steganography. I have detailed these papers …

I have started reading background material on general steganography and video encoding in preparation for my dissertation. However, there are very few books that cover video steganography. Therefore I have been reading material that covers audio and image steganography. While these books do not deal with the video, …
