Dynamic code anti-counterfeiting method and system

Abstract

The invention discloses a dynamic code anti-counterfeiting method and a system, and the dynamic code anti-counterfeiting method is characterized by attaching a dynamic code anti-counterfeiting recognizer and a password lock on a commodity, leading each dynamic code anti-counterfeiting recognizer to have a unique machine code, leading the dynamic code anti-counterfeiting recognizer to generate cryptograph of an anti-counterfeiting code through an encryption formula based on the machine code, time and a key, leading a consumer to obtain the cryptograph through the recognizer, submitting the cryptograph to a server by using the telephone, the short message or the network way, leading the server to carry out decryption according to the cryptograph, the time of the server and the key, obtaining the machine code, further being in contrast with the machine code stored in a database, feeding back the authenticity and a password to the consumer, and leading the consumer to open the password lock attached on the commodity through the password, wherein the machine code which is inquired once can not be re-inquired. The system has simple structure, few elements, low production cost and good anti-counterfeiting effect, and can replace a traditional anti-counterfeiting label for use.

Description

technical field [0001] The invention relates to a dynamic code anti-counterfeiting method and system, belonging to the technical field of anti-counterfeiting. Background technique [0002] In the prior art, the counterfeiting and shoddy phenomenon of high-end commodities is very serious, such as expensive tobacco and wine, high-end clothing, famous watches and accessories. Some counterfeit and shoddy products are even disguised with used packing boxes of original products, making it difficult for consumers to distinguish between genuine and fake. An existing anti-counterfeiting query system is to affix an anti-counterfeiting label on the product, and distinguish the authenticity by querying a group of anti-counterfeiting codes on the anti-counterfeiting label. The anti-counterfeiting label is too simple, and the anti-counterfeiting code is easily stolen.

Problems solved by technology

Some counterfeit and shoddy products are even disguised with used packaging boxes from the original factory, making it difficult for consumers to distinguish between genuine and fake

An existing anti-counterfeiting query system is to affix an anti-counterfeiting label on the product, and to distinguish the authenticity by querying a group of anti-counterfeiting codes on the anti-counterfeiting label. The anti-counterfeiting label is too simple, and the anti-counterfeiting code is easy to be stolen

Chinese patent 200510021125 discloses a dynamic code digital display code electronic label anti-counterfeiting system, which can provide dynamic anti-counterfeiting code information query. It is found through use that the anti-counterfeiting method adopted by the system is too complicated, which leads to the complex structure of the electronic label used and high production costs.

At the same time, the electronic tag can be opened directly without inquiring, and the product can be taken out for use. Therefore, consumers may be unwilling to inquire, resulting in the failure of the anti-counterfeiting technology, and the manufacturer cannot collect the consumption information of the product in time.
