H.264/AVC videos are used in a wide variety of applications. In this study, several methods for data hiding applications, namely, covert communication, copyright protection, and video sharing, are proposed using H.264/AVC videos as cover media. For covert communication, we propose a large-volume method and an optimal method for hiding secret data in H.264/AVC videos, based on the use of prediction modes and tree structured motion compensation. The optimal method is a tradeoff between hiding capacity, imperceptibility, and low bit rating. For copyright protection, in order to protect the ownership of downloaded videos at the client site, a method using a removable visible watermarking technique with a scheme for display control on specified computers is proposed. For the application of secret sharing, we share the data of the prediction modes of a secret video based on exclusive-OR operations and hide the resulting share data into the prediction modes of cover videos. The resulting share videos are then distributed to participants to keep. By collecting the share videos owned by all participants, the secret video can be recovered. Good experimental results show the feasibility of the proposed methods. Wen-Hsiang Tsai 蔡文祥 2008 學位論文 ; thesis 76 en_US |
