Abstract :
In this paper, we propose a data hiding approach to hide related information in MPEG-2 videos for their retrieval, inspired from the spirit of digital watermarking. By hiding the retrieval-related information in the MPEG compressed codes, significant advantages are gained. Our experiments on hiding more than 20 bits averagely in every 3 frames illustrate that no noticeable distortion is introduced in comparison with nonwatermarked frames. The information hidden in the video can still exist after video is down-scaled for users with transmission bandwidth.
