A novel zero-watermarking scheme based on NSCT-SVD and blockchain for video copyright

Abstract With the advent of information era, the issues on video copyright continue to emerge. In the grey industrial chain of piracy, the film industry is suffering a major disaster area. The current protection schemes for video copyright are inefficient and costly so that video industry still has to face the infringement. To address poor robustness, weak imperceptibility and difficulty in traceability of the current protection schemes for video copyright, this paper proposes a novel zero-watermarking scheme based on NSCT-SVD and blockchain for video copyright. In addition, we research the feasibility and reason of combining zero-watermarking with blockchain. The designed zero-watermarking algorithm is based on NSCT-SVD, Arnold Transform and key-frames extraction algorithm which is based on distance threshold clustering. The results show the extracted features from video are stable and secure than DWT-SVD based and the past non-blocking. The performance of the blockchain scheme designed for video copyright practices well. Comparatively, the discussion and results showed that the proposed scheme has been verified more credible and efficient in authoritative traceability compared to trusted third party based. The registration information cannot be tampered and be more suitable for copyright protection.
