Creating test material for computer forensic teaching or tool testing
purposes has been a known problem. I encountered the issue in my studies
of Computer Forensics at the University of Westminster. We were
assigned a task to compare computer forensic tools and report results.
Having already analysed test images by Brian Carrier
(http://dftt.sourceforge.net) over and over again, I found myself
creating images manually, which appears to be the best and only way of
doing this. One of my lecturers, Sean Tohill, confirmed this is indeed
the case and a test image generator is long overdue.
The need for such a tool is twofold. In educational setting, the problem
of plagiarism can be mitigated by giving each student an individual
image to analyse. In application quality testing, one of the tests
should be to feed several similar but not identical images to the
forensic tool, and compare results, which should be identical...
