Anti-forgery System Research Based Barcode

With the development of economy and fiercer competition of market, as well as theincreasing and extension of commodity distribution model, sale region and circulationspeed, it’s of universality and importance for enterprises to recognize, restraint andpunish illegal operations, such as fleeing goods and forge fast and accurately in thelogistics.In this paper, the system of product anti-counterfeiting and synthetic logisticsmanagement will be designed, to provide anti counterfeiting and synthetic logisticsmanagement in production, transport, storage, sale and after sale as well as data queryand logistics network management. It is the available and effective way for consumersto distinguish the fake product from genuine one and enterprises to grasp circulation aswell.Based on bar code, this system puts forward the solution to guard against fleeinggoods and prevent forgery with hardware-software integration system. As theinformation carrier, bar code has various features including product origin, manufacturer,manufacture date and product classification. Therefore, using information retrieval andcollected by computer and communication network management, bar code can identifyproducts and control the circulation and marketing segments.The key technology of bar code is described and working principle as well assecurity technology is analyzed. The cause of bad behaviors such as fake commoditiesand goods fleeing in the logistics is discussed, while the solution is put forward throughprocess control, technology application and information query. Making and assemblyprocess of bad code are also studied on in this thesis. Thus, overall design, processmodeling and database design of this system is based on target and demand analysis.In addition, in the field of system analysis and design, demand need is analyzedfrom the perspective of feasibility, service management and system case. From thisresult, layers of system general structure is presented by further studying in workingprocess and designing service module management. Meanwhile, the database is set in detail, including data processing, data sheet structure and the constraint system of dataintegrity. To describe the achievement of the system and design target, the thesis utilizesfront-end application platform and background management. Furthermore, the system istested and applied evaluation.Coding realized, the practical operation of system shows that the limitation of timeand space in product checking is broken through, product status is indentifiedconveniently and efficiently, control and trace capability of enterprises in the field ofcirculation is improved, bad behaviors such as fake commodities and goods fleeing inthe logistics is prevented, thus promoting the informatization and modernization inlogistic management.
