英文摘要： The joint technique of video watermarking and encryption is the foreland in the field of the information security。This project focuses on the research on a novel video watermarking and encryption scheme, that is, reversible-watermarking and encryption integration, abreviated by reversible-watermarking encryption.The main research content is as follows: 1) The secure model on the video reversible-watermarking encryption is designed and established, therefore, the foundation of security mechanism is laid; 2) Single-image hybrid reversible-watermarking encryption scheme is studied, which solves the problem on the multi-function protection such as the content and copyright of the image and so on; 3) Image-group reversible-watermarking encryption scheme based on compression sensing is researched, which improves the effeciency of the encryption and decryption of image group such as the continuous capture images and so on; 4) Video reversible-watermarking encryption scheme based on motion vectors is proposed, which solves the real time and practicality problem of the video using the multi-function protection. Therefore, through this project, the general secure theoretical model on the reversible-watermarking encryption can be obtained and the firm foudation for the application on the joint technique of
