Abstract: 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 bination
of two dimension bar code and digital watermarking technology. Finally this paper p
