【摘要】：随着国家经济水平的不断提升,大众的消费水平也逐渐提升,商品消费市场空前盛大,在巨大的利润驱动下,不可避免地出现了大量的假冒伪劣产品。给消费者的权益带来损害,给合法厂家的信誉和利益带来巨大的伤害。为了遏制商品中的假冒伪劣产品的肆意增长,打击假冒伪劣产品,荧光防伪、印刷薄膜防伪、隐藏标记防伪、电话防伪等多种防伪手段相继出现,,但是随着造假水平的提升,这些防伪手段都不能很可靠的作为真假商品验证的依据。这种情况下,急需一种新的技术手段来解决这个问题,RFID技术与防伪领域的结合成了解决这个问题的切入点,然而初级的RFID标签识别方法,容易被造假分子通过复制标签攻破。本文针对这种缺陷提出了基于一次一证体制的商品防伪系统设计思想,并对其进行了实现。本文研究的主要内容包括:(1)通过分析现有的基于RFID技术进行防伪的系统的不足点——标签验证信息固定不变。针对这个缺陷提出了新的改进方案在每一次验证后都改变标签的验证数据,也就是一次一证思想的原始模型。这样就使标签复制变得没有意义。(2)在提出一次一证体制的系统方案后,对系统的整体框架进行了设计,把系统划分为发证服务、手机平台服务、验证服务、客户端APP,明确各个部分的功能,进一步对各个功能模块的实现提出了要求,接着概略性地对各个模块的细致划分进行了介绍,此外,针对本系统的特殊性做了系统容错设计。(3)根据各个模块的设计要求,对系统进行代码实现。其中服务器程序是基于C#语言开发的,客户端APP是基于Android开发的,客户端的通信采用Android Volley框架,服务器端的通信采用Web API框架,都是基于Http协议的通信,最后将RFID标签融入系统就算完整了。系统实现完成之后对整个系统进行了黑盒测试、核心模块单元测试,并展示了复制标签只能其中一个通过验证,从而佐证了一次一证的防伪思想。本文首先介绍了RFID技术在商品防伪领域的研究状况,提出本文的创新点。然后对本系统会涉及的相关技术做了介绍,接着对系统的需求进行分析并选择了相关技术路线,然后对系统框架进行了设计。之后描述了系统核心模块的实现方法,随之对系统一次一证特性、验证功能等进行了测试和评估。最后对全文进行了总结,并对系统的进一步完善。
[Abstract]:With the continuous improvement of the national economic level, the consumption level of the masses is also gradually increased, the commodity consumption market is unprecedented grand, driven by huge profits, inevitably appeared a large number of fake and inferior products. Bring damage to consumers' rights and interests, and bring great harm to the reputation and interests of legitimate manufacturers. In order to curb the wanton growth of fake and shoddy products in commodities, combat fake and inferior products, fluorescence anti-counterfeiting, printing film anti-counterfeiting, hidden marks anti-counterfeiting, telephone anti-counterfeiting and other means of anti-counterfeiting have appeared one after another, but with the improvement of the level of counterfeiting, These anti-counterfeiting measures can not be very reliable as a basis for the verification of genuine and fake goods. In this case, there is an urgent need for a new technical means to solve this problem. The combination of RFID technology and anti-counterfeiting field has become the starting point to solve this problem. However, the primary RFID tag recognition method is easy to be breached by counterfeiters by copying tags. In this paper, the design idea of commodity anti-counterfeiting system based on one-time-one-certificate system is put forward, and its realization is carried out. The main contents of this paper are as follows: (1) label verification information is fixed by analyzing the shortcomings of the existing anti-counterfeiting system based on RFID technology. In view of this defect, a new improved scheme is proposed, which changes the validation data of label after each verification, that is, the original model of one-proof idea. In this way, label replication becomes meaningless. (2) after putting forward a system scheme of one-pass certificate system, the overall framework of the system is designed, and the system is divided into license service, mobile platform service, authentication service, and client-side APP,. This paper clarifies the functions of each part, further puts forward the requirements for the realization of each functional module, and then introduces the detailed division of each module in a general way. In addition, According to the particularity of the system, the fault-tolerant design of the system is made. (3) according to the design requirements of each module, the system is implemented by code. The server program is developed based on C # language, the client APP is developed based on Android, the communication of client side is based on Android Volley framework, the communication of server side is based on Web API framework, all of which are based on Http protocol. Finally, the integration of RFID tags into the system is complete. After the implementation of the system, the whole system is tested in black box, and the unit test of the core module is carried out, and it shows that only one copy tag can pass the verification, thus corroborating the anti-counterfeiting idea of "one certificate at a time". In this paper, the research status of RFID technology in the field of commodity anti-counterfeiting is introduced, and the innovation of this paper is put forward. Then the related technologies involved in the system are introduced, then the requirements of the system are analyzed and the related technical routes are selected, and then the system framework is designed. Then it describes the implementation method of the core module of the system, and then tests and evaluates the characteristics and verification functions of the system. Finally, the full text is summarized, and the further improvement of the system.
