In the paper, we present an efficient algorithm to hide information in MPEG compressed video. In order to utilize the large amount of video streams, and to speed up the process of hiding information, we provide an algorithm that makes use of compressed coefficients to hide information directly. The advantage of the method is that we can make use of DCT coefficients directly without compressing and decompressing. We have experimented with the algorithm, and the result of experiment indicates that the performance of the algorithm is efficient.
