Research of Two Dimension Bar Code and Digital Watermarking Technology

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.
