Due to my current assignment workload, I am not where I wanted to be with my literature survey, but I have made a good start within the last couple of hours. There is a lot of background material for steganography, all with varying degrees of relevancy. I have decided to start the literature survey by explaining the …

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 …

So far, I have just implemented the basic Image and Audio steganography methods, which are exposed via the Tools section of this …

I have started developing a swing application in Java that I will use to how all of the steganography tools and techniques I develop. …

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, …
