Research And Design Of Anti - Counterfeiting Ticket Detection Device Based On Digital Watermarking

Ticket is the admission to watch the Olympic Games and visit the scenic spots. Currently, as the development of high quality image input and output device, the fake of special image such as tickets, becomes easy, which results in adverse effects to the social morality and also brings certain economic losses of enterprises.In order to combat the piracy phenomenon effectively, it’s important and positive to research on a high efficient and convenient anti-fake detection device of tickets.Digital watermarking is a hidden technology which is close to the actual application. It has the ability to hide the characteristics and resist various malicious attacks, such as tickets and any printed products. Without changing the printing process, materials and equipment, unique superiority of digital watermarking, can play a role in the technology of anti-fake tickets. So this paper mainly studies anti-fake tickets detection device based on digital watermarking and conducts the following research work. Firstly, this article introduces the research background and the current situation of development at home and abroad. And also summarizes the basic theoretical knowledge about digital watermarking.Secondly, for the image digital watermarking technology, it describes several commonly used methods.It contains empty set algorithm, DCT and DWT_DCT algorithm. Under the Matlab platform, researchers do some experiments, and through comparative analysis, DWTDCT algorithm owes good hidden effect and strong robustness.So it is more suitable for ticket anti-counterfeiting.Then, we discuss the composition of anti-fack tickets detection device and chose DSP chip-TMS320VC5509A of TI as the core processor for whole detection device, it also discribes the hardware platform and completes the design of application program in the DSP software development platform.Finally, the device was tested. From the experimental results we can see, it has certain feasibility with anti-fake tickets detection device based on digital watermarking.
