A Digital Watermarking Scheme for Authenticating H.264/AVC Compressed Videos

Abstract

In this research, we propose a digital watermarking scheme under the framework of H.264/AVC. The scheme is mainly used for video authentication to ensure that the frame or shot order in a video be maintained. The watermark signal is embedded into quantization indices of intra-coded frames to achieve the effective watermark embedding/detection and preserve the compact size of video data. The luminance masking of Watson’s visual model is employed to guarantee the imperceptibility of watermark signal. The coding procedure of H.264/AVC is taken into account in the design of watermarking procedures for the efficient execution. The experimental results demonstrate the feasibility of the proposed video authentication system.
