1. A method for extracting a fingerprint of a video having a plurality of frames, the method being executed by one or more processors and comprising:
extracting the plurality of frames from the video;
obtaining a plurality of pixel value matrices from each of the plurality of frames;
calculating maximum values of average pixel values in each axis of the plurality of pixel value matrices for each of the plurality of frames;
calculating the fingerprint of the video based on a temporal correlation of the maximum values calculated for the plurality of frames; and
comparing the fingerprint of the video with the fingerprint of an original video and determining if the fingerprint of the video is within an error range of at least a portion of the fingerprint of the original video.
