Design and Implementation of Video Copyright Protection System Based on LabVIEW and Water Transfer Printing Materials

Abstract

In view of the problems of the traditional digital copyright protection system which can’t fully protect the digital content and was vulnerable to be cracked, a video copyright protection system based on LabVIEW was proposed. The system used the basic theory of LSB algorithm, and embedded the watermark information into lowest position of DC about the DCT coefficients of the I-frame of video. The system can’t only have the good robustness under the premise of the invisibility of watermark but also realize the watermark blind extracted, achieving the requirement of the watermark embedded and extracted real-timely. The experimental results show that the algorithm has good robustness. The system has the advantages of operating easily, easy to be upgraded, low cost and has good prospect for application.
