The Ikena Copyright system produces a collection of hashes from existing video content. These hashes are then run against new video to attempt to find matches. Unlike other fingerprinting technologies, Ikena Copyright generates hashes based on motion and not color or audio. A problem facing video hashers is that it is not difficult to obscure video attributes such as color, size, audio or resolution. Most hashing software is easily fooled by the traditional bootleg video which is made by recording directly off a TV or Movie screen. Ikena Copyright, MotionDSP claims, can detect such bootlegs because it is much more challenging to alter motion. Ikena Copyright’s major competitor is Audible Magic, which filters video for Google’s YouTube.
