Key Techniques Research Of Digital Publishing Based On The Exynos

Digital publishing is a kind of new form of publishing and with the emergence of the Internet technology is developing rapidly, the publishing content is stored on the CD, hard disk and network in the form of digital signal. With the rapid popularization of intelligent mobile terminal, digital publishing has obtained the huge development, even appearing trend to replace the traditional publishers. Although digital publishing has merits of fast, convenient and so on, it also caused the emergence of the phenomenon such as piracy, so need to study of digital copyright management, guarantee the healthy and orderly development of digital publishing. Digital publishing includs music, books, video, etc., due to video technology is most complex and is bigger, so this article were mainly studied for video copyright management technology.This paper introduces the traditional video encryption technology first, on the basis of the summary, summarized their characteristics this paper proposes a new encryption algorithm, encryption algorithm, it is to choose the important elements to encrypt in the video data, then design the thinking process. This paper experiment device of choice is Exynos platform, the platform of the operating system is the Android system, the article introduced the operating system kernel and file system download and compilation process, and made a detailed introduction to the download the source code of the directory structure and the key file directory, after successfully compile the system image files, copy it to Exynos platform.Finally design the video encryption and video decryption software, being used to encrypt and decrypt a video, the video encryption software is running under the Windows operating environment, video decryption software is running in the Android operating environment. Analyze the data of video encryption effect experiment, first with a video encryption software for video encryption, and then copy the encrypted video to Exynos platform, with decryption video broadcast video software, and then using ordinary player video broadcast encryption, judge the effect between video display, finally concluded that perceptual encryption algorithm is able to protect digital copyright.
