With reference to specific embodiment, the present invention is described in detail.Following examples will be helpful to the technology of this area
Personnel further understand the present invention, but the invention is not limited in any way.It should be pointed out that to the ordinary skill of this area
For personnel, without departing from the inventive concept of the premise, some changes can also be made and changed.
(commodity unique identifier is by brand side's public key by the public key and commodity unique identifier of buyer and seller by the present invention
Constituted with the coding rule of brand side oneself) and additional information (such as time) give into.This data structure, next time
The public key of the seller must be the public key of last buyer, may thereby determine that the legitimacy in source.
Data of the present invention have the ability of self-validation in itself.By rivest, shamir, adelman encryption data, the seller will with private key
Encrypted transaction data, only his public key could be decrypted.As long as because of the public key successful decryption for needing to be announced with him, it is possible to determine this
Data is issued by the seller really.The transaction each time of commodity all writes block chain, can be by commodity unique identifier in area
The All Activity record of the commodity is retrieved on block chain.Whether it is merchandise next time in by the public key for contrasting last transaction buyer
The public key of the seller, forms a complete article ownership transfer record, it is possible to it is determined that whether the current seller is the commodity
Lawful owner.
As shown in Figure 1 and Figure 2, the present invention provides a kind of anti-counterfeit tracking verification method based on block chain, including following step
Suddenly：
1st, the seller announces its seller's public key by official channel.
When the 2nd, selling direction buyer delivery, with vendor private key, by buyer data (public key) and merchandise news, (commodity are uniquely known
Other code, date of manufacture etc.) and the information such as exchange hour signed, antifalsification label is formed, and write block chain, while will be anti-
Pseudo label issues buyer, signed data information can be built in inside commodity or an external Quick Response Code or
Its carrier of phase.
3rd, buyer is received after goods, the seller's public key verifications seller's signing messages announced with seller official, is such as verified,
Then whether there is the respective record of write-in block chain in block chaining search.If any, then it represents that goods is received, is really sold by certified products seller
Go out, be genuine article.
If the 4, buyer has used a period of time, want to change hands and sell, need also exist for buyer (at this moment former buyer is changed into the seller)
The information such as information and merchandise news and exchange hour is signed, and writes block chain, then by the information of commodity and signature
Together deliver to buyer.
5th, buyer is received after goods, and with the public key verifications of the seller, while being searched on block chain, whether seller is last
Buyer's (block chained record has the public key of buyer, and contrast public key is assured that) of transaction, if it is, represent to buy is just
Product.
If the 6, commodity are then commercially circulated to by way of being sold agency.Brand business passes through same stream
Journey is agential information write-in block chain is issued, and then the information for issuing retailer is write block chain by agent again.If
Retract, the information that also should also return goods write-in block chain.

true；Otherwise false is returned.True is such as returned to, then by procuration is true.Then, buyer is by commodity unique identifier, in area
Inquired about in block chain.If the commodity are to sell for the first time, then an only data in whole block chain.I.e. the seller is brand
Business, buyer is oneself.If repeatedly sale, or multi-layer agent resell.So sell or resell each time, all can
There is a record in block chain.Moreover, the public key of seller next time, it is necessary to be the public key of last buyer.If handed over twice
Yi Zhong, the public key of seller is different from the public key of last buyer next time, then explanation is fake products.Explanation：As transaction flows through journey
In, return goods.Buyer (return of goods side) in transaction, need to be as the transaction seller, and write-in one recorded block chain, and be labeled as
Return goods.The so real seller, acquires the legal of the commodity and possesses identity again.If there is a seller centre, nourish malice,
Two are deliberately write in block chain, makes commodity transaction circulation record chaotic, that earliest time is defined by the time for we.
