an infeasible ipm for an exact maximally complementary solution to the p horizontal lcp 水平线性互补问题精确极大互补解的不可行内点算法
digital watermarking technique is an efficiency tool of copyright protection . being compared with encryption, it overcomes the shortcomings of encryption technique in multimedia copyright protection, and provides the complementary solution for encryption technique 数字水印技术是解决这一问题的有效途径,在多媒体版权保护方面具有加密技术所不具有的优点,并且与之有着很强的互补性。
information hiding technique becomes a research hot-spot in recent years . it overcomes the shortcomings of encrpytion techniques in information security and multimedia authentication, and provides the complementary solution for encrpytion techniques 信息隐藏技术是近年来人们研究的热点之一,其在信息保密、多媒体版权保护方面有着加密技术所不具有的优点,并且与之有着很强的互补性。
it overcomes the shortcomings of encrpytion techniques in multimedia version protection and multimedia authentication, and provides the complementary solution for encrpytion techniques . starting with the practical requirements, this paper gives an analysis on the current work of digital watermarking related to the multimedia authentication thery, and researches on the modern cryptography theory 本文从图像认证的实际需要出发,分析了目前数字水印在认证方面已有的工作和研究现代密码学的基础理论,阐述了二者在认证方面各自的特点和各自的局限性,提出将二者结合起来设计在理论上安全的水印算法。
