电子书数字版权保护的技术模型初探——以三新书业的探索为例

Sanxin's Practice & Research on Digital Rights Management of E-Book

本文基于对数字版权保护研究现状的分析,界定了数字版权保护的内涵。在研究通用型DRM的主要功能、使用场景以及交互模型的基础上,论述了通用型DRM实际上是通过密钥对数字内容进行技术加密,从而大大地抑制了电子书从终端盗版的难度。利用通用型DRM构建起来的三新DRM技术模型,不仅最大程度地借鉴前者的优点,使内容出版商可直接掌控密钥,制作可跟踪授权码,而且同时具备通用性好、安全性高以及适用范围广等特点。

Based on the analysis of current research on digital copyright protection, the paper defines the connotation of digital copyright protection. Through studying the main functions of universal DRM, basic usage scenarios and interaction model, it advocates the fact that universal DRM is actually the protection technology for digital content by encrypting, which greatly inhibited e Book piracy from terminal. Sanxin DRM models, built on universal DRM, not only maximize the advantages of the universal DRM, which makes content publishers directly control the keys and trace authorization codes, but also possess a wide range of features, such as great commonality, high safety, and wide application.
