隨著網際網路發展，眾多的數位內容在網際網路上散播。因此，數位內容以及影像的安全性逐漸變成一項重要的議題。由於數位內容的特性極容易經由網際網路傳播與複製，故數位內容所有權人的權力將受到極大的威脅。然而就算市場上有許多保護資料安全性的產品，對一般的使用者來說那些商品還是都過於昂貴。
本研究著重於隱形浮水印技術於影片的檔案格式之中，利用的線上免費公開的隱形浮水印技術工具實作一項服務，提供眾多的一般使用者能於網頁上進行資料的加解密步驟，保護其所需要加解密的檔案。此外本研究也提供了主動式的驗證機制於數位內容中，有別於以往的被動式驗證。 / With the digitalization of media, the improvement of video compression technique and the adaptation of the Internet, videos have become one of the most prominent mediums in the network age. However, due to its nature to be easily copied and distributed, creative workers easily become victims to the piracy. While corporations use proprietary digital rights management (DRM) to guarantee fair use of intellectual properties, individuals are seldom able to afford huge royalty.
In this work, we investigate invisible watermarking techniques, discuss their properties, and apply cryptography and steganography techniques to data hiding in digital contents. Specifically, we develop a new public online service of data hiding in digital contents with the aim of proving content owners the ability to claim digital ownership. The current technique used to embed messages in video satisfies integrity but cannot resist attacks/modifications on the video. Also, we proposed a generic active authentication framework via hiding programs in digital contents, giving the developer the possibility to design their own variant from passive authentication to active code execution.
