Design And Implementation Of A Duery And Verification System For Card Information Based On Multidimensional Barcode

In today's society, making fake cards is increasingly rampant. And how to enhance the card anti-counterfeit technology has become the key to the question. Moreover, there are so many different kinds of cards in current China. There are some difficulties in sharing of information because each management institution is fiercely independent. As a result, it has caused serious waste of resources in information collection, transmission, storage and other links.To solve the above problems, and in order to query, verify and manage the card information uniformly, this paper puts forward an implementation scheme for a query and verification system for card information by applying a new type of self-developed multidimensional barcode. It uses multidimensional barcode to store various biological characteristics including face, fingerprint, signature, iris and more. Then we attach multidimensional barcode to the card after encryption and encode. And the system scans the barcode on cards, queries and authenticates their authenticity in the database according to the decoding results of barcodes.To begin with, the paper introduces the current actuality of barcode technology, the application of the technology in card and the shortage of the cardinformation management, comes up with a method of applying the multidimensional barcode fused with biometric information to the card security as information carrier and managing card information uniformly. Secondly, it presents a card security and management pattern of application architecture and describes the detail requirement analyses and system architecture detailedly. Then the designed scheme is carried out on the basis of overall and detail design. The framework of the system adopts B/S model. We develop browser-side by HTML, JavaScript, CSS as front-end development technology. And It is suitable to use Apache, Mysql, PHP as Server-side. At last, it uses functional tests and performance tests to make sure the feasibility and reliability of the system. It also analyzes the deficiency of the system and the development direction.Through plenty of research and analysis, the design and programming, the system not only can complete the query and the verification task according to the multidimensional barcode, but also can manage the different types of card information. The system is efficient in dealing with the query and verification of card information and embodies the advantages of the multidimensional barcode.
