Video fingerprinting apparatus in frequency domain and method using the same

The video fingerprinting method and apparatus is disclosed. Video finger print inserter of the present invention is the fingerprint by selecting the frequency domain for selecting the frequency regions of the fingers frequency region to be printed is inserted into the video part, on the selected frequency range based on the fingerprint insertion decision value to determine where to insert the fingerprint insertion position determination portion, and characterized by including the fingerprint is inserted with a power setting in position to be inserted the fingers to insert the fingerprint bit string printed insert parts. Thus, the fingerprinting attack, such as video fingerprinting system and method in the frequency domain of the present invention, the re-compression, filtering, and video format changes due to insertion of the finger print in the selected frequency range after converting the video image into the frequency domain it is robust.
