Content Based Fingerprinting for Video Copyright Detection System
Security of a fingerprinting system is important for certain applications such as copyright protections, for this reason secure version of the fingerprinting system for video piracy detection is presented. The proposed system relies on a fingerprint extraction algorithm followed by a fast approximate search algorithm for video piracy detection. The fingerprint extraction algorithm extracts content based signatures from special images constructed from the video. Each such image represents a short segment of the video and contains temporal as well as spatial information about the video segment. These images are denoted by temporally informative representative images.
