The process of collection, preservation and analysis of digital forensic data is normally followed by presentation of findings by forensic examiner. At this stage it is important for non-forensic people (legal etc.) to clearly understand the significance of uncovered evidence. Visualisation can help to make this task a lot easier by displaying the findings in a graphical manner, making even small details visible and demonstrate the relationship between various pieces of evidence.
A variety of commercial and free open source software can be utilised to accomplish this task. A free and open source graphical time line editor called
Zeitline and commercial
ConceptDraw MINDMAP are worth mentioning here.
Zeitline is an open source graphical tool written in Java developed and maintained by
CERIAS (Computer Forensics Research Group).
ConceptDraw MINDMAP is a
mind mapping software that normally cost US $199. It appears that the company is offering the previous version of this software free for a limited time. You can find more details at Lifehacker's
web site.
