Videntifier™ Forensic provides police authorities with an automatic and easy-to-use video identification system. A single mouse click is sufficient to automatically scan an entire hard drive for suspicious and illegal video material. With its speed, Videntifier™ Forensic saves investigators precious time, which they can spend on other more challenging tasks, rather than inspecting thousands of video files manually. At the end of each scan Videntifier™ Forensic returns a summary report, listing which videos have been identified.

The service can detect even severely modified or truncated versions of the same video, which easily fool checksum-based systems. The identification process itself is extremely efficient, even for very large video collections. The service can inspects each hour of video within 30 seconds and can run continuously, day and night.

Videntifier™ Forensic builds on a huge database of visual fingerprints, so it can identify most commonly available video material. A visual fingerprint is extracted around specific interest points in the individual frames of a video. It encodes the visual signal around these points into a sequence of numbers, that is then stored in Videntifier Technologies' patent protected database. As each video contains many thousand frames and each frame up to a few hundred points, Videntifier™ Forensic extracts about 150,000 visual fingerprints from each hour of video.

Currently, Videntifier™ Forensic contains over 6 billion video fingerprints in its patented database, representing about 70,000 hours of video content. The database has been growing since the official start of the service in December 2009. Our first customer, the Icelandic police, did extensive testing and practical evaluations on the system before full deployment. The chart below shows the identification rate in tests of three actual cases. As the database grew, the identification rate also went up. Therefore Videntifier Technologies continues collecting fingerprints, enabling Videntifier™ Forensic to remember more than 100,000 hours of video by the end of 2011.
