Anti-counterfeit apparatus and method for cigarette by passive radio frequency label

Abstract

The invention relates to a device and a method for processing cigarette anti-fake by using passive RF. A factory stores product incompatibility after encrypting EPC code of the product, one part is solidified in ROM of a RFID reader, other part is solidified in the RF label embedded in the cigarette packaging box, a fake EPC code generated by logical calculus to a whole EPC code is printed on the cigarette packaging box sealing drawing line when the product is packaged, the method generates fake EPC code by processing logical calculus to the whole EPC code in the RFID reader ROM solidifying, the RFID reader identifies cigarette authenticity and whether channel conflict by comparing with the fake EPC code printed on the cigarette packaging box sealing drawing line and the fake EPC code generated by the reader calculating. The method and the device are easily to be realized and have low cost which can increase difficulty for counterfeiting.

Description

technical field [0001] The invention relates to the technical field of electronic anti-counterfeiting, in particular to a device and method for anti-counterfeiting of cigarettes using passive radio frequency tags. Background technique [0002] my country has already implemented a monopoly system on tobacco. However, due to the huge profits of the tobacco industry, the phenomenon of counterfeiting and selling tobacco, especially cigarettes, is still rampant. It also causes a large loss of national tax revenue. Using radio frequency identification technology for anti-counterfeiting is a very good method. The published Chinese patent CN201111092Y "electronic anti-counterfeiting system for boxed cigarettes" installs radio frequency electronic tags on cigarette boxes, and non-contact RFID radio frequency identification readers read RFID The identity information in the radio frequency identification electronic tag is transmitted to the manufacturer's data processing center through...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: to solve the existing electronic anti-counterfeiting system of boxed cigarettes that must rely on the Internet, which is not conducive to popularization in rural and remote areas; and the technical problem of poor anti-counterfeiting effect. The device and method for anti-counterfeiting of cigarettes on labels increases the difficulty of counterfeiting. Although counterfeiters may copy part of the EPC code in the label, they cannot read another part of the reader, and cannot calculate the counterfeit code based on the complete EPC code. EPC code to achieve anti-counterfeiting
