High-Accuracy Watermarking Scheme on H.264 Based on Majority Voting

In this paper, we use video watermarking on H.264 video compressed, to reach protect for video data. In recent years, H.264 is a new advanced video compressed standard. It provides high compression efficiency and compress quality, digital data is easy to be altered. One of the most important things is to prevent the data to be illegally used. We propose a method is compare many corresponding AC coefficient, to embed watermark information of I Frame, and compare corresponding AC coefficient to extract watermark by majority. Additionally, results show that watermark extracting to possess high accuracy as well as the watermark information can be effective against the impact of video compression.
