Abstract
The invention discloses a method and system for carrying out anti-counterfeit authentication on a commodity by a two-dimensional bar code. The two-dimensional bar code is marked on the commodity; the consumer reads a two-dimensional bar code image by an image reading device and uploads the two-dimensional bar code image to an anti-counterfeit authentication system of the commodity so as to carry out anti-counterfeit authentication; and the two-dimensional bar code is generated after being treated by an encryption algorithm according to characteristic information of the commodity; and the treatment process of the anti-counterfeit authentication system is as follows: receiving the two-dimensional bar code image of the commodity uploaded by the consumer; positioning, decoding and identifying the two-dimensional bar code image so as to obtain two-dimensional bar code data; and processing the two-dimensional bar code data by a decryption algorithm so as to generate and display characteristic information of the decrypted commodity. According to the invention, multiple anti-counterfeit authentications can be carried out in a repeated way; moreover, no coating covering is needed for the two-dimensional bar code so that the quality traceability of the commodity in the transferring and circulating link is guaranteed, the method and system disclosed by the invention are beneficial for largely increasing the commodity anti-counterfeit authentication query rate and the anti-counterfeit and anti-fraud consciousness of the consumer is actually enhanced.
Description
Technical field
The present invention relates to a kind of commodity carried out the method and system of anti-fake certificate, especially a kind of method and system of utilizing two-dimensional bar code commodity to be carried out anti-fake certificate.
Background technology
Along with the trust crisis that the recent public produces the varieties of food items quality problems, the commodity counterfeit prevention problem becomes the focus of citizen and the concern of all kinds of producer.Commodity counterfeit prevention always is a headachy problem.Phone authentication sign indicating number false-proof authentication system has effectively been contained the batch forgery to name brands, has made major contribution for cracking down on counterfeit goods.At present, phone authentication sign indicating number false-proof authentication system is adopted by numerous domestic enterprise.
The ultimate principle of phone authentication sign indicating number false-proof authentication system is: every product all has one group of unique encoding, is called authentication code, and coated sealing is attached on product body or the packing.After the consumer purchases commodities, can dial the Antiforge inquiry phone of Unified National, authentication code is inquired about.Inquired about like authentication code, then commodity are identified as fake products, as are inquiry for the first time, then are identified as genuine article.
Compare with other anti-counterfeiting technologies, phone authentication sign indicating number false-proof authentication system is simple and easy to do, is very easy to the consumer.But the phone authentication sign indicating number is false proof shortcoming is arranged also, extremely low such as phone authentication sign indicating number examination probability, the anti-counterfeiting power of authentication code own is not enough, and the false proof enterprise of phone authentication sign indicating number is too indiscriminate too much etc., particularly also exist fake products can not detect with genuine article be the problem of fake products by false retrieval.As time goes on, the consumer has lost confidence to it gradually, and anti-counterfeiting mark can not be false proof.The false proof industry of phone authentication sign indicating number is being faced with trust crisis.
In addition, phone authentication sign indicating number false-proof authentication system only supplies disposable inquiry, and this information is cancelled after the inquiry, is unfavorable for the transfer of commodity; Phone authentication sign indicating number false-proof authentication system technology does not have the follow-up of quality function.Adopt local inquiry phone, various places enquiring telephone number disunity, inquiring about to the consumer has increased difficulty.After using 168 information telephones, though unified enquiring telephone number, inquiry service is provided by information station, the every inquiry of consumer once all will be paid certain telephone charge and information charge.This part expense is born by the consumer, and is not only unreasonable, and the consumer is reduced through the incidence of calling the inquiry behavior greatly, can not form enough deterrences to the fraud seller of the fake goods, is unfavorable for false proof.Therefore, need badly a kind of facility simple to operate of exploitation, and can multiple authentication the anti-counterfeiting authentication method and the system of commodity true and false.
Summary of the invention
The technical matters that the present invention will solve is: a kind of method of utilizing two-dimensional bar code commodity to be carried out anti-fake certificate is provided; This method is through generating the two-dimensional bar code of these commodity of sign after AES is handled to the characteristic information of commodity; Realized the corresponding one by one of two-dimensional bar code and commodity; This method is easy and simple to handle, and sustainable multiple authentication commodity, is convenient to the follow-up of quality of commodity in the process of circulation.
Another technical matters that the present invention will solve is: a kind of commodity counterfeit prevention Verification System is provided, and this system can repeat repeatedly commodity to be carried out true and false authentication based on the two-dimensional bar code that includes the commodity characteristic information after encryption.
In order to solve the problems of the technologies described above, the technical scheme that the present invention adopted is:
