What is digital forensics?
Computers hold a wealth of information unseen. To the untrained eye, data may well be gone, deleted forever. This is however most commonly not the case.
Using state-of-the-art software and hardware processes we are able to recover e-mails, conversation threads, photographs, files and related data to show traces of what has been done when and how on computers, laptops and tablets.
Similarly, we are able to enhance (reasonably) photographs and CCTV footage, as well as establishing if such imagery has been tampered with.
This information can be vital to a criminal or civil investigation and can be the evidentiary data required to close a case. In recent years Digital Forensics (including Cellular Forensics and Data recovery/ digital image verification) has become a growing industry across the world. Examiners are generally trained in an IT discipline and also experienced investigators or have undergone further training in Forensics to include law of evidence etc. This is blended with technology that changes on a monthly basis in terms of assessment tools, equipment and software required.
When acquiring forensic information for our clients we are always mindful that the final results of our work are most likely destined for a courtroom where we can be called as expert witnesses in digital forensics and cellular forensics in order to confirm the credibility of the evidence.
Do not take chances with "someone who knows computers/ phones" or has nice software that they downloaded off the internet as this will affect the integrity of the evidence. It is imperative that proper chain of evidence is maintained at all times.
