在現今的數位時代，絕大部分的資訊皆由數位傳播，數位傳播不僅有傳統實體傳遞的功能，更突破傳統的限制。但是數位技術也相對的降低了拷貝資料的難度，任何人都可以輕地拷貝數位資料，技術門檻和成本相對較低且複製品與原件幾乎相同，因此當數位資訊被非法業者複製並販售後，對於數位著作權持有者的利益變會造成巨大的損失，因此保護數位資料便成為一個重要的議題。但是對中小企業或私人發行者來說，現在市面上的資料保護機制都需要收取相當高的許可費用與複雜的使用流程。 在本論文提出一個有效率且簡易使用的資料保護機制，提供低成本且相容性高的數位影片防拷貝功能，可以自行對資料進行保護且不用額外的解密機制便可播放影片。本系統藉由使用多種影片源來與播放平台測試，顯示此保護機制有良好的相容性，可於各大平台上播放且具有保護資料的能力。;With the great advances in technology, the software industries have made a great progress, and the way to send data of digital media is also in a constant innovation. The digital technology reduces the difficulty of copying data. Everyone can copy digital data easily, and the replica is the same the original. So when the digital media content is copied and sold by unscrupulous operators, it will cause huge losses to the video industry. How to add the protective mechanism in the Blu-ray disc (BD) becomes another issue which we concerned about. However, the cost of using a commercially available Digital rights management (DRM) system is relatives high to the production budget of small and medium enterprises and small and home offices. In this paper, we propose an efficient and simple content duplication protection scheme. Our system provides a low-cost and high compatible content protection function that users can protect the content without any extra mechanisms and play the protected BDs in the player without decryption. We conduct an experiment to test on different video samples and different platform. The result shows that our protection scheme is compatible with most of the Blu-ray player. The protected BDs can be played in the multi-vendor players and can’t be copied on the computer.
