Real-Time Implementation of Blind and Robust Watermarking for HEVC Video Coding

Abstract

The propose video watermarking algorithm is blind and robust which is suited for the HEVC standard. The algorithm uses DCT coefficients correlation concept using integer DCT transform. The robustness of the algorithm is improved by significantly against temporal attacks by embedding the different parts of the same watermark in various frames of a particular video. The real-time watermarking is performed to insert watermark at the time of capturing video itself. The performance of the algorithm is measured with NC, PSNR and BER. The algorithm shows normalized correlation values more than 98% in case of various temporal attacks. The proposed scheme posses excellent BER value which also confirms its admirable robustness comparison of related work. The hardware implementation reveals the adaptability of real-time watermarking.
