Abstract :
Information Hiding is a good method to transmit important information secretly. Video sequences usually include many frames, so they have more room to hide information. In the paper, in order to increase the amount of hiding information, we choose MPEG sequences as hosts, and we present a practical method to hide information in MPEG compressed video. Generally, there are many B-frames in each GOP. We utilize the B-frames to hide information, so that we can increase the amount of hiding information and decrease the tamper of the hosts. In order to increase the correctness of receiving information, we make use of Hamming code to check the errors of receiving information. Hiding and extracting are performed in compressed video sequences without requiring original video. The experimental results show that the proposed method has the characteristics of less tampering the visual effect, larger hiding capacity, and the validity of receiving information.
