摘　　要：数字水印技术被认为是对数字图像进行版权保护的一种科学而有效的方法。提出了一种基于陷门单向函数的空域水印算法,目的是为图像的版权保护设计一个高度安全的水印系统。实验结果证明该算法对诸如位置攻击、不重要位攻击、多幅图像攻击等具有较强的鲁棒性。Digital watermarking techniques have been proposed for the copyright protection of digital images recently.In order to design a secure watermarking system for copyright protection of image, this paper proposed a new watermarking scheme based on Trap-Door One-Way Functions in spatial domain.The experimental results show that the proposed algorithm is robust against attacks such as position attack,the less significance bits attack and multiple images attacketc.

关 键 词：数字图像水印 版权保护 陷门单向函数
