The application of RFID technology in anti-counterfeiting technology

traditional anti-counterfeiting technology is not unique and exclusive, easy to copy, and can not play a real anti-counterfeiting role. At present, the international anti-counterfeiting field has gradually risen a trend of using electronic technology to prevent counterfeiting, and RF tags have attracted extensive attention in the anti-counterfeiting community

for a long time, fake and inferior commodities have not only seriously affected the economic development of the country, but also endangered the vital interests of enterprises and consumers. In order to protect the interests of enterprises and consumers and ensure the healthy development of the socialist market economy, the state and enterprises spend a lot of human and financial resources on anti-counterfeiting and anti-counterfeiting every year. However, most of the anti-counterfeiting technologies used in the anti-counterfeiting products on the domestic market are still based on paper-based materials. Common anti-counterfeiting technologies include holographic patterns, color changing inks, general technical conditions for concealed steel fire-proof roller shutters on products and packages GB 14102 (9) 3 mark. Its technology is not unique and exclusive, easy to copy, so it can not play a real anti-counterfeiting role. At present, there is a trend of using electronic technology to prevent counterfeiting in the field of international anti-counterfeiting, especially the use of RF tags, whose advantages have attracted widespread attention

rfid anti-counterfeiting currently has several views: first, it is completed by a unique ID number, and at the same time, it is equipped with some algorithms to realize security management. The other is hardware method. This method is because the contactless card electronic tag is embedded with a chip and contains a globally unique code, which can only be recognized by readers and writers with the same code

compared with other anti-counterfeiting technologies such as laser anti-counterfeiting and digital anti-counterfeiting, RFID technology has the following advantages: each tag has a globally unique ID number, which is placed in ROM when making chips, and cannot be modified or imitated; No mechanical wear and dirt; The reader/writer has a physical interface that is not directly open to end users to ensure its own security; In terms of data security, in addition to the password protection of the label, some algorithms can be used to realize the security management of the data part; There is a process of mutual authentication between reader writer and tag

at present, some breakthroughs have been made in the use of RFID technology for anti-counterfeiting applications at home and abroad

I. document anti-counterfeiting

at present, RFID tags can be embedded in the cover of standard passports or documents in terms of passport anti-counterfeiting and e-wallets. Its chip also provides security functions and supports hardware encryption, which conforms to the international standard of iso14443. China has also formed a considerable scale of applications in this field, and the promotion and application of the second-generation ID card is a typical representative in this regard

second, ticket anti-counterfeiting

in this regard, some applications urgently need RFID technology. For example, in places with a large number of people, such as railway stations, subways and tourist attractions, RFID electronic tickets are used to replace traditional manual tickets to improve efficiency, or RFID technology is used to prevent ticket counterfeiting in occasions with large ticket volume, such as competitions and performances. Not only does it no longer need manual identification to realize the rapid passage of personnel, but also it can identify the number of tickets used, so as to prevent tickets from being stolen and used again, so as to achieve "number anti-counterfeiting"

III. packaging anti-counterfeiting

in order to combat counterfeiting, the manufacturer of Oxycontin, an American anesthetic, announced that it would adopt radio frequency technology (RFID) on drug bottles. To realize the whole process of electronic monitoring of drugs from production to pharmaceutical factories is an effective means to combat the growing phenomenon of drug counterfeiting. Drugs, food, dangerous goods and other goods are closely related to personal safety in daily life, and they are special goods under state supervision. Its production, transportation and sales process must be strictly managed. Once the management is unfavorable and scattered to the society, it will inevitably bring great threats to the safety of people's lives and property. Our government has also begun to use RFID technology to meet their needs with the help of domestic leading manufacturers in the field of RFID (such as Weishen Electronics)

in addition to its anti-counterfeiting function, RFID tags also have outstanding features such as non-contact recognition, recognition of high-speed moving objects, resistance to harsh environments, strong confidentiality, and simultaneous recognition of multiple recognition objects, so it can be used in a wider range of occasions. In foreign countries, radio frequency tags have been widely used in industry, commerce, transportation, logistics and many other fields. Its unique high accuracy and quickness greatly reduce the logistics cost of enterprises, and improve the market competitiveness and service efficiency of enterprises

illegal personnel forge certificates, and illegal enterprises produce fake and shoddy products, shoddy, and make exorbitant profits. Once fake and shoddy products enter the market, they are easy to cause major accidents, affect the stability of social order, undermine the situation of stability and unity, and affect the economic construction of the country. The wide application of RFID anti-counterfeiting technology will not only bring direct economic benefits to enterprises, but also correctly, timely, dynamically and effectively supervise the production status of special goods production and operation units for relevant national management departments, crack down on and ban illegal production activities, plug management loopholes, eliminate potential safety hazards, ensure the safety of life and property of the country and people, and maintain social order and stability, Provide strong technical support for the sustainable development of the national economy. At the same time, it is conducive to improving the efficiency of management and operation, reducing operation costs, enhancing administrative management, further improving the decision-making level and ability of instruments, fixtures and software, and improving the image of the government. Its social role is far greater than the direct economic benefits

recently, the Institute of automation of the Chinese Academy of Sciences launched a commodity after-sales service system based on RFID technology, which provides an anti-counterfeiting authentication platform for commodities. RFID authentication platform introduces hardware and business based structure at the same time, providing basic information of goods and offline authentication. The working principle is: the coding of goods adopts double code system. The manufacturer assigns two codes to each product, namely product code and internal code. The product code is the unique code assigned to the commodity by the manufacturer according to the corresponding coding standard when producing the commodity. This number is a clear code that consumers can see when purchasing the commodity. With this number, consumers can query the relevant information of commodities in the commodity information database provided by the manufacturer. Internal code refers to the internal code of the commodity given by the manufacturer according to its own production and management needs and the enterprise regulations. This number can include the relevant production supplementary information of the commodity (such as batch, raw materials, production time, processing technology, etc.), or a password associated with the commodity information database provided by the manufacturer, or other meanings given by the manufacturer. The internal code is a secret code, which is encrypted by hardware or software algorithm and written into the electronic label. The key is held by the manufacturer and confidential to others, including after-sales service personnel

manufacturers also need to establish a commodity information database to store the relevant information of goods that have left the factory. Product code and internal code correspond to the same database, but they have different access rights. When consumers buy goods, the seller's reader reads the product code and internal code (only the authorized reader can read), and the authenticity of the goods can be identified by querying the manufacturer's commodity information database

at present, the Swiss watch industry is about to adopt RFID technology for anti-counterfeiting. Swiss winwatch company is committed to developing and applying for the licensed patent of intelligent property and the patented solution of applying RFID technology to various Swiss watches. At the same time, they hope to become the patent issuer of RFID inlay technology on the clock surface

considering the influence of metal case on antenna frequency reception. Winwatch inlays rfidtag into the surface glass of the watch to prevent counterfeiting, identify and track the watch. And this technology has been certified by the Swiss government in 2003

according to the above introduction, it is found that there is a high voice for the application of RFID in anti-counterfeiting. However, there are many problems in the application of RFID anti-counterfeiting. For example, the first one mentioned above, if you use a unique ID number to prevent counterfeiting, some tags can be read and written. You can write the read tag ID into a new tag, which has no effect on anti-counterfeiting. In addition, if the algorithm is used for security management, it is bound to create SMM news: Zhejiang Wali New Energy Technology Co., Ltd. has made a breakthrough in the upgrading of lithium battery manufacturing materials, and the commodity information can not be generally readable, resulting in a considerable number of readers and writers unable to read

for the second kind of anti-counterfeiting, it belongs to the anti-counterfeiting technology of instrument identification because special instruments must be used for identification. When applied to commodity anti-counterfeiting, there are two fatal defects that are difficult to overcome. That is, the following two questions:

1. Who is using the "reader writer" (identification instrument)? Are you a consumer or a business employee? Who guarantees that the "reader writer" is true? Has the material analysis, inspection and supervision widely used in iron and steel metallurgy, factories and mining enterprises, quality supervision, colleges and universities, scientific research institutes, construction engineering and building materials, aerospace and other industries been 'outsourced'

2. Can electronic labels be recycled (by counterfeiters)

therefore, the common weakness of the anti-counterfeiting of the former unique id+ security algorithm and the latter due to the application of instrument identification anti-counterfeiting technology in the field of commodity anti-counterfeiting is the problem of "how to ensure the security of identification instruments on the premise of widespread use". When applied to the field of commodity anti-counterfeiting, there are still many problems that need to be deeply considered and studied
