Research And Application Of Identification Management Based On Two Dimensional Barcode

The identification of Chinese residents is identification card, it is involved inevery area of life, so the certificate anti-counterfeiting technology has been hot inresearch. The second generation ID card use RFID technology, but it can be easilyduplicated and faked, so it is necessary to adopt new technology to increase the abilityof credentials anti-counterfeiting.The paper decide to implement identification card management based on twodimensional barcode because two dimensional barcode has a lot superiority, and canimplement ID information data collection automation. Technically, two dimensionalbarcode doesn’t have the ability of anti-counterfeiting, but it can implementanti-counterfeiting with other digital technology.This article reads as follows:(1)The choose of two-dimensional barcode technology and the implementationof barcode Generation system: On the basis of making detailed research on PDF417encoding technology, This article decide to implement barcode Generation systembased on PDF417encoding which is fit for text and picture.(2)The research of digital watermarking technology: Adopting digitalwatermarking technology can increase the ability of credentials anti-counterfeiting.This paper design a digital watermarking algorithm for the identification cardmanagement system, and This algorithm has proved effective from all-around andmultiple directions which can be use in identification card management.(3)This article does research on the random key technology of pseudofingerprint characteristics, and the technology is used in two dimensional barcodeencoding technology and watermarking embedding algorithm to achieve the identityof people and credentials in credentials management of certificate managementsystem.(4)The design and implementation of identification card management system:firstly, This article introduces the design of identification card management systemand some key modules,for example, card building module and card authenticationmodule, which can meet application needs.
