Guide To Video Authentication Analysis

Forensic video analysis is the scientific examination, comparison and/or evaluation of video in legal matters. Forensic video analysis services assist the trier of fact to determine the authenticity of a video recording.

Evidence recovery is the best way to authenticate a digital video recording. There is a wide range of software that help in video authentication.

How Video Analysis Is Done?

  • Preliminary Analysis

Experts inspect the video and perform initial testing to determine the scope of the investigation. They prefer to only enter investigations if we feel our forensic services will be of assistance to the case.

  • Digital Integrity Verification

Digital integrity verification testing will generally reveal any evidence of tampering first. The types of testing we perform include HASH verification, meta-data, EXIF and HEX testing to name a few.

Experts can also provide exemplar (controlled sample) comparison testing to determine if a recording is consistent with what we would expect to see from an original.

  • Pixel/Frame Analysis

Sometimes our investigations require further testing to confirm authenticity. Frame by frame, motion vector, macro-block as well as physical equipment testing is required to determine the authenticity of recordings based on the behaviour of video pixels, as well as individual video frames.

How Crime Scene Investigation Is Done?

Let's look through the basic processes that underlie crime investigation. What we see in the show is just a replica of what is actually happening with the real criminal investigations but there is more to it. This will not only solve problems through logic. 

Let's go behind the scenes of how the real process of introducing the culprit.

The first stage is to investigate crimes when investigators arrived and secured a spot. Expert uses different software to analyse the investigation case in great detail. Many companies such as Cognitech which provide real-time image and video processing and analysis software tools to analyse the investigation correctly.

Nothing was touched. What investigators do is the formulation of possible theories about the actual occurrence and speculation and predictions about it. 

Typically, securing an investigator if something has been removed, altered, or modified before he arrived. The first step is to conduct an initial inspection of the premises.

The next step is to document the scene through pictures, videos and sketches. investigators saw to it that every angle has been documented for analysis. 

No one touches the creatures still during this process. The next step is to get a real touch of anything that could be used as evidence.

Investigators are now touching, collect and document specimen that is of relevance and is estimated to have a relationship with evil. 

This is where the investigator tags, logs, and pack all available evidence needed for logical analysis. 

This level also allows investigators to make its way to the scene that does not leave behind the specimen. Everything had to be closed for its minute details
