Eyewitness accounts recorded in the digital video may not always be accurate. It is a common misconception in today’s courts that the fact that a video can skip or jump indicates that it has been edited or manipulated. Additionally, a video may not be considered reliable or authentic if it does not contain accurate metadata or misrepresents an actual event. When digital integrity is a concern, forensic video authentication services add weight to crucial evidence.
Criminological video examination is the logical assessment, correlation, and assessment of video in legitimate issues. The trier of fact can use our forensic video authentication services to verify the authenticity and origin of video evidence. Our efficient video authentication software services can identify edits or manipulation in a video recording.


Video Evidence Most Times Isn’t Top Notch
Body-worn cameras, police dashcams, and videos taken by mobile devices have gained a lot of value in court as digital video evidence from surveillance systems have increased. However, videos are susceptible to manipulation, which can directly result in recording mishandling or misrepresentation at the time of acquisition. Video evidence can be used as a weapon if the digital information or foundation of the video recording is not correctly interpreted or decoded. However, video recordings are fragile. A video with these problems can be thought to have been manipulated.

Processes Involved In Video Authentication

  • Introductory Analysis:
    At this phase, to determine the scope of the requirement, we examine the video and conduct initial testing. We can also determine whether the video is an authentic copy or an original at this stage. We prefer to enter investigations when we are confident that our video authentication services will assist your case. To put it another way, we never ask for a retainer until we know that video forensics can assist.

  • File Makeup Analysis:
    We can provide software manipulation detection and verify the source of a digital video recording at this testing stage. Questions like “how the digital chain of custody was handled?” and how long a video file has been around?” can be answered with our tools.

  • Global Analysis:
    A video image’s local inconsistencies, such as copy/paste/clone detection or compression artifacts, can be identified through temporal or spatial frame analysis. Motion vector and macro-block testing can be carried out frame by frame to ascertain the behavior of particular pixel regions.

  • Photo Response Non Uniformity Analysis:
    The PRNU Analysis takes a picture of a camera’s noise profile to be compared to an unidentified image or video recording and verified. The origin of a video recording can be identified by our specialists.

Wrap Up
Video authentication is the process of ensuring the fidelity of a digital video which is somewhat related to video forensics. Digital video’s integrity is protected by a video authentication system, which ensures that the video being used has not been any way. For digital right management, copy control, or authentication, customized data is embedded in digital content, such as an image, video, or audio, through digital watermarking. When authentication systems reject any digital content modification, fragile or semi-fragile watermarks are typically used for authentication. The idea is to use a hash value to verify the digital data.
