What is forensic video analysis?
Forensic Video Analysis is the scientific examination comparison and/or evaluation of video in legal matters. Our forensic video analysis services assist the trier of fact to determine the authenticity of a video recording. Through video authentication analysis and forensic science we can provide edit detection and tampering services. Many of our clients believe that their digital video recordings are manipulated or edited. We often find that when people experience a traumatic event, their interpretation of the event is altered. Some clients even believe because a video has been edited, that is is not authentic.
Digital video recordings aren’t always an accurate eyewitness. The Rules of Evidence require that digital video recordings used as evidence be authentic. In other words, the video recording must contain all relevant portions to the investigation and maintain authenticity of those events. However, video recordings can be edited if the portions of the recording that are removed are not relevant to the investigation.
The Rules of Evidence state that editing a video recording to remove irrelevant portions will not effect its authenticity. This can be confusing to a lay person which is why a video forensic expert is retained. We are brought in as a third party unbiased scientist to perform video authentication services.
THE IMPORTANCE OF AN ORIGINAL VIDEO RECORDING
Often times we receive video evidence that has been improperly copied/maintained, and makes the analysis process difficult. The Scientific Working Group on Digital Evidence (SWGDE & IOCE) defines Original Digital Evidence as:
“The physical items and the data objects associated with such items at the time of acquisition or seizure.”
If the video is not maintained properly, it may not be considered an authentic representation of an original either. When a copy has been produced as evidence that is not an original. It’s important for everyone involved in the litigation to agree that the video is an authentic representation of the events.
When the video evidence has been extracted from the system that created it, it is susceptible to manipulation and tampering. It is so crucial to ensure that the chain of custody of the copy submitted as evidence is maintained properly.
CHAIN OF CUSTODY
It is important that the creator of the video recording provide chain of custody documentation. Chain of custody documentation explains how the evidence was handled. This handling would be from the time it was created to the delivery to an investigator. Some common questions that are answered in the chain of custody documentation are:
These types of questions must be answered before beginning an investigation to determine if the authenticity of the chain of custody. Even if someone viewed the video recording while in their possession, that activity must be noted in the chain of custody.
Another method we use to investigate the digital integrity is to analyze the chain of custody. Specific digital information bout the system that created it strengthens the authenticity of the chain of custody. This assists the expert in gathering information to create any sample recordings needed for the investigation.
The best way to authenticate a digital video recording is to perform a evidence recovery. This process ensures that the original digital video evidence is preserved, extracted and maintained to establish an authentic chain of custody. The integrity and authenticity of the recording is challenged less often if a qualified forensic video analyst recovers it from the original system. To learn more about this process click HERE.
