QIM-Based Semi-Fragile Watermarking for H.264 Video Authentication
The paper presents a semi-fragile watermarking system designed for H.264 video authentication. The proposed system embeds a semi-fragile watermark into integer DCT coefficients of each keyframe of a video at the H.264 quantization step. The system localizes modified video regions of size 4×4 with close to 95% accuracy. The experimental part demonstrates the influence of the embedding process on the visual quality of the protected video and the watermark extraction error for different H.264 quality parameter values.
