Multiple anti-counterfeiting mechanisms based on RFID (radio frequency identification)

Abstract

A product anti-counterfeiting tracking mechanism based on an electronic tag comprises the electronic tag, fractal codes and anti-counterfeiting codes, wherein the electronic tag consists of a chip and an external antenna, every tag has a unique electric code which is attached on an article to identify a target object; on the basis of multi-sector content of the electric tag, the fractal codes utilize randomly generated internal codes of an encryption chip to generate a unique fractal pattern by adopting the Newton fractal method as a generation rule, and the unique fractal pattern which is taken as unique identification of the chip is implanted to package; when the chip is taken out of the package, or the package is exchanged, the fractal pattern is damaged inevitably, so that the chip is prevented from being reproduced and exchanged; by virtue of the electronic tag, matched read-write equipment is configured, and then information relative to the article can be read and written in at any time; by virtue of the fractal codes, the product can be prevented from being exchanged, or the chip in the article package can be prevented from being produced; and the anti-counterfeiting codes are a series of bar codes, a consumer can query related information of the article by virtue of the anti-counterfeiting codes, and authenticity of the article is further verified.

Description

technical field [0001] The invention belongs to the technical field of article anti-counterfeiting and is mainly used for anti-counterfeiting and traceability of products. Background technique [0002] 1. At present, the phenomenon of commodity counterfeiting in various industries is becoming more and more serious. The root cause of the failure to effectively curb it is the lack of effective, reliable and easy-to-implement anti-counterfeiting methods. Therefore, for the entire market, especially food, Chinese medicinal materials, cosmetics, milk powder and other industries closely related to human life safety, it is particularly necessary to establish an effective anti-counterfeiting mechanism. [0003] 2. The RFID (radio frequency identification devices) system is mainly composed of three parts: tags, readers, data transmission and processing systems. Electronic tags include chips and external antennas. The combination of antennas and chips forms information transmission in...

Problems solved by technology

[0004] 3. However, the anti-counterfeiting application of RFID in the existing market has not formed a system, and the electronic tags in RFID alone cannot fully achieve the purpose of anti-counterfeiting, because there are loopholes in the anti-counterfeiting performance

[0005] 4. In addition, in the existing RFID anti-counterfeiting applications, many products do not consider the query needs of end users. End users need to have a card reader matched with electronic tags to query the information users want, which is extremely inconvenient for users to query.
