A method for automatically authenticating unknown video data based on known video data stored at a client server is provided, wherein, unknown and known video data each are made up of segments and include metadata, a hash message digest, and a serial code. The method involves selecting a first segment of the unknown video and locating the serial code within the first segment of the unknown video data. The serial code is used to locate a corresponding first segment in the known video data. The first segment may include a known hash message digest. A new hash message digest for the first segment of the unknown video data is generated and compared with the known hash message digest. If they match, the segment of unknown video data is authentic.
