个人文献数字水印版权保护系统摘 要如今，网络技术发展得如日中天，信息存储的方式发生了日新月异的变化，个人数字作品大部分开始以数字形式在存储在网络中。数字媒体在传输过程中能够被完美的复制和粘贴，在打印或扫描过程中容易被广泛传播。因此，数字化个人作品的完整性面临着各种挑战，网络上也常会出现个人作品版权问题的纠纷。对个人数字作品用简单的加密只能在数据传输过程中起到一定的保护作用，但当数据被接受并解密后，个人数字作品的简单加密只能在数据传输过程中起到一定的保护作用，但当数据被接受并解密后，简单的数字加密方法就不能再提供实质性的保护。同样，单方面地用使用水印作为版权标识也起不了实质性的保护作用。本系统从数字水印技术（Digital Watermark Technology,DWT）的特点入手通过结合公钥加密算法来开发一个基于“文本加密+数字水印+权限管理”的版权保护方案系统。本系统采用三种技术的结合，使用 C++开发环境来实现 PDF 文本文献的数据安全保护。降低了个人文本文献在共享时存在的安全隐患。关键词：数字水印 ；公钥加密；版权保护ABSTRACTNowadays, network technology is developing day by day, and the way of information storage has undergone rapid changes. Most of personal digital works are beginning to be stored in the network in digital form. Digital media can be perfectly copied and pasted during transmission, and it is easy to spread widely during printing or scanning. Therefore, the integrity of digital personal works is facing various challenges, and disputes over copyright issues of personal works often occur on the Internet. Simple encryption of personal digital works can only play a certain protective role in the process of data transmission, but when the data is accepted and decrypted, simple encryption of personal digital works can only play a certain protective role in the process of data transmission However, when the data is accepted and decrypted, the simple digital encryption method can no longer provide substantial protection. Similarly, the un...
