摘要
本文首先介绍了信息安全中的三种主要技术:认证访问控制技术、密码技术和数字水印技术。然后介绍了数字水印的基本原理和在信息安全中的应用。最后,从理论研究、应用基础研究和应用研究三个层次,介绍了数字水印的研究现状,提出了数字水印研究的一些有价值的方向,指出数字水印的研究必须在理论研究上取得突破才可能真正获得广泛应用。
In this paper, three kinds of main technology on information security is introduced at first: Which is authen-tication and access control technology, Encryption technology and digital watermarking technology. Then the basicprinciple of the digital watermarking and its application in the field of information security are introduced. Finally, fromthree levels of theoretical research, application basic research and application research, we have introduced therecent research situation of the digital watermarking, have put forward the valuable direction, point out that theoreti-cal research must be made break-through before digital watermarking will be extensively applied.
