图像水印算法研究新进展

A Novel Survey on the Image Watermarking Algorithms

随着信息网络化飞速发展,数字水印作为网络环境下数字图像版权保护和完整性验证的重要技术,得到了广泛研究和应用。本文综述了图像水印技术的最新进展情况,阐述了图像水印的关键技术,分析了鲁棒性水印算法、半脆弱性水印算法和脆弱性水印算法的主流方案、特点和最新进展。最后,展望了图像水印技术的发展趋势。

With the rapid development of computer and information technology,as the key techniques of digital image copyright protection and integrity authentication,digital watermarking has been widely studied and applied.An overview of the recent developments in image watermarking is introduced,and the main techniques of image watermarking are illustrated.We discuss the main schemes,characteristics and new development of the robust watermarking,fragile watermarking,and semi-fragile watermarking algorithms.Finally,the development trend of the image watermarking technology is discussed in this paper.
