Digital Forensics Basics – Part 2

Digital forensics is commonly used in conjunction with computer forensics to either support or refute a possible hypothesis being considered during an investigation. By using digital re-enactments and creating similar conditions through digital means, investigators can reproduce an event in great detail. They can also add variables that can help to determine time, duration and location when those elements would otherwise remain unknown.

While it is not fool proof, a digital recreation of an event can shed valuable light on a crime scene that may have been overlooked by the initial investigation. By taking known elements and combining them with computer generated graphics and animation, an investigator can digitally enhance or reproduce images that may be too grainy or blurred when looked at with the naked eye.

To create a digital recreation of an event or moment in time, an investigator must enter every detail into the software. When an investigator starts with what is known, he or she can add variables to produce possible outcomes. This can create accurate time lines and all show a pattern of activity if a crime was committed over several months time.

Digital forensics is a virtual playground when it comes to tools and techniques. With the right training, a technician can literally re create something with a few key bits of information.
