Multicast video fingerprinting scheme with genetic algorithm

Abstract

Comparing to the unicast or broadcast methods, it is more efficient to transmit video data via the multicast method to massive users. However, the ease of delivery of video data may cause a problem to copyright protection, and the fingerprinting scheme is one of effective means for conquering this problem. Fingerprint embedding process often generates the multimedia contents into many different versions, which have to be transmitted via the unicast method. In this paper, we propose a new fingerprinting scheme with the aid of genetic algorithms for copyright protection of multicast video. Experimental results demonstrate that the proposed method can transmit multimedia data to clients effectively and cause only a slight degradation in perceptual quality.
