计算机技术和网络技术特别是 INTERNET 的日益发展,使得信息的发布和传输实现了数字化和网络化,为档案资源的开发利用提供了条件。但是数字化的信息在发布和传送过程中是极容易被篡改的,使利用者无法判断接收到的档案信息是否安全,是否真实,更谈不上利用档案的凭证作用。为了数字化信息传输的安全,防止信息被攻击和篡改,出现了许多信息加密技术,如数字签名、密码技术等,但是这些加密技术使信息在传输过程中不可见,最重要的是用户在解密之后仍不能确定所得到的信息是否被篡改,因此需要一种不同于传统加密技术的更有效的手段。一种近年来不断发展的新的信息隐藏技术——数字水印技 The growing development of computer technology and network technology, especially INTERNET, has enabled the digitalization and networking of information release and transmission, and provided the conditions for the development and utilization of file resources. However, the digitized information is very easily tampered with in the process of distribution and delivery, so that the user can not judge whether the received file information is safe, whether it is true or not, let alone the effect of utilizing the voucher of the file. In order to secure the transmission of digital information and prevent the information from being attacked and tampered with, many information encryption technologies have emerged, such as digital signatures and password technologies. However, these encryption technologies make the information invisible during the transmission. The most important thing is that after the user decrypts Still not sure if the resulting information has been tampered with, and therefore a more efficient means than traditional encryption techniques is needed.
