Design And Implement A Tape Encryption And Watermarking Video Playback System

With the rapid development of information technology, multimedia technology has been rapid. It is gradually becoming the necessary part of people’s working, learning and life. Besides with the development of network technology in the information industry, it has become the fastest growing part. In the past twenty years in the fluency of multimedia technology, security, real-time, compatibility and other aspects of a comprehensive upgrade have been perfected in the life cycle of data and information-collection, storage, transmission and destruction-any stage of development into a mature mechanism, but due to the current user needs specialized and extensive development of multimedia technology in two directions, namely the pursuit of a more professional and to pursue a more compatible, so even multimedia technology engineering research and development for many years, it’s still positive.In this thesis, in order to solve production problems encountered in practice, from the collection, storage, reprocessing, video information security certification, present a practical solution. The main work is as follows:●Using MFC to write the overall framework of the system. In order to playback and audio videos.●Using DirectShow technology to complete the acquisition and storage of video information.●Taking H.264video coding standard for the collection of information for further compress for easy storage.●RC4stream encryption algorithm to complete maintenance information and add watermark to information security certification.In this paper, for the realization of safe storage of video copyright protection provides a practical reference scenario, in real life has a positive effect.
