摘要
二维条码技术凭其自身的高容量、高密度、高纠错能力等优点,已被广泛应用于各行各业,因此二维码技术在安全防伪方面的应用以及研究也日益重要。数字水印技术是信息隐藏技术的一个重要分支,其对数字内容的版权保护有重要实用价值和实践意义。文章首先简单介绍了二维条码技术的基本概念、特征、应用现状等。然后总结概述了近几年来二维码技术和数字水印技术结合的一些研究成果,分析和讨论了部分典型算法,并指出了二维条码水印技术今后可能的一些发展方向。
As the two dimension bar code＇s much advantages, such as big capacity, high density and great error correcting ability, the two dimension bar code technology is widely used in different walks of our life increasingly. Simultaneously, the research of two dimension bar code technology in anti-counterfeiting and security field application is increasingly indispensable. And the digital watermarking technology which is an important branch of information hiding technology, has significantly practical value to the digital copyright protection. Firstly, this study introduces the two dimension bar code technology＇s concept, characteristics and its application status simply. Then summarizes and analysis the recent research achievements of the combination of two dimension bar code and digital watermarking technology. Finally this paper points out some could be research development directions of the combination of two dimension bar code technology and digital watermarking technology.
