InvariMatch identifies videos previously uploaded to a database that are similar or identical to the video sample the client wants to search for. InvariMatch identifies videos previously uploaded to a database that are similar or identical to the video sample the client wants to search for. The software identifies duplicate copies. The copies are identified even when color schemes are changed and/or resolution of the video is low quality. Same as Google or Bing search for text, TinEye – for pictures, and Shazam – for music, InvariVison processes videos and conducts a reverse search of the database to find full or partial copies of videos. InvariMatch allows the creators of video content to be informed where and how their video content was used, either in full or partially. It allows the agencies that protect copyright rights to automatically be informed when the rights of their clients are being infringed upon. It allows video hosting companies to scan uploaded videos to find undesired content even in a format of short clips inserted into a video file. This function allows to compile blacklists and prevent the upload of duplicate files not congruent with the policies of the hosting agency.
