Anti-counterfeiting method based on RFID electronic label

Abstract

The invention discloses an anti-counterfeiting method based on an RFID electronic label. According to the method, binding is carried out between an ultrahigh frequency electronic label and a product that needs an anti-counterfeiting process. An RFID electronic label is composed of a password reservation region, an electronic product code (EPC) memory region, a tag identification (TID) memory region, an electronic article surveillance (EAS) functional position and a user data memory region; the password reservation region is used for storing an access password, and a killing instruction; the EPC memory region is used for writing an EPC number or a bar code of the product or a coding number defined by a manufacturer in the EPC memory region; The TID memory region is solidified on a label chip and is used for storing information like a manufacture code and an EPC serial number and the like; the EAS functional position is used for storing antitheft and alarm information of the product and is set into an alarming state during the process after the product leaves the factory; and the EAS functional position will be modified into an non-alarming state when the EAS functional position is in a store; and the user data memory region is used for writing a circulation area coding number of the product and an agent coding number and the like in the user data memory region and each area in the internal memory region is provided with password protection. According to the invention, it is not easy for an illegal RFID reader to obtain electronic label information, so that product counterfeiting is avoided.

Description

technical field [0001] The invention relates to an anti-counterfeit method, in particular to an anti-counterfeit method based on RFID electronic tags. Background technique [0002] Medicines are special commodities for preventing and treating diseases and ensuring human health. However, there are often reports in the media about the manufacture and sale of counterfeit medicines. With the deepening of medical system reform and the implementation of drug classification management methods, the proportion of patients choosing their own drugs is gradually increasing. If counterfeit and shoddy products will seriously affect the health of consumers, and even endanger their lives. With the increase of pharmaceutical sales channels, it is imminent to strengthen the anti-counterfeiting of pharmaceutical packaging. Existing drug anti-counterfeiting methods include visual anti-counterfeiting technology (such as laser laser labels, special packaging, etc.), telephone password query anti...

Problems solved by technology

At present, a few industries, such as the Wuliangye wine industry, have begun to use RFID technology for anti-counterfeiting, and the products are affixed with RFID electronic tags to uniquely identify the products. Among them, some use high-frequency (13.56MHz) RFID technology, while others Using ultra-high frequency (860-960MHz) RFID technology, the disadvantage of using high-frequency RFID is that the information stored in the tag chip is plaintext information, which can be easily obtained by illegal RFID readers to cause counterfeiting, and high-frequency RFID technology The sensing distance is very short, and the medicines cannot be processed in batches during the storage and circulation process; the disadvantage of using UHF RFID is that the internal storage structure of the currently used UHF RFID tag chip is as follows: figure 1 As shown, it does not have a solidified unique ID number, and its EPC number (Electronic Product Code, Electronic Product Code) can be rewritten and read by illegal readers at will, so it is also easy to cause counterfeiting
