The following describes a block chain-based anti-counterfeit inspection scheme for goods according to the present disclosure in detail by using specific examples. The following examples illustrate banknotes and invoices, respectively, as anti-counterfeiting carriers, and banknote crown word numbers and invoice codes, respectively, as unique codes. It is to be understood that any vector which achieves the same technical result can be used to carry out the solution according to the invention.
In the solution using banknotes as carrier, the crown-word number of the banknote is used as the unique code. The specific embodiment is as follows:
example one
The unique code on the bank note is also called a crown word number, the crown word is two or three English letters printed on the bank note for marking a printing batch, and the two or three English letters are arranged and printed by a bank note printer according to a certain rule; the number is an Arabic numeral serial number printed behind the crown word and used for indicating the arrangement sequence of each banknote in the same crown word batch. Taking the RMB as an example, the crown word consists of 2-3 Roman digits or two Chinese phonetic alphabets, and the number consists of six, seven or eight Arabic digits. The serial number is used for indicating the batch number of various printed tickets, the serial number is the specific serial number in each serial number, one ticket is one serial number, and the serial numbers in the same serial number are not repeated. Taking the fifth set of renminbi circulating at present as an example, it implements the twenty-eight arrangement of 2-bit crown words and 8-bit numbers, the maximum combination of 2 hanyupinyins is 625, the combination of 10 arabic numerals is one hundred million, so the maximum theoretical value of the printed number of each note of the fifth set of renminbi is 625 hundred million.
The crown word number has the characteristics of strong anti-counterfeiting performance, one bill and one number and large issuing quantity, and in addition, the crown word number is easy to identify as an anti-counterfeiting mark, the mark can be considered as true by verifying that the bill is a true bill, and the paper bill cannot be manufactured by means of copying, counterfeiting or counterfeiting.
The block chain technology and the crown word number are used for commodity anti-counterfeiting inspection, and 2 execution main bodies are involved, namely a merchant and a user. The merchant arranges intelligent contract anti-counterfeiting service, initializes intelligent contract, registers banknote crown word number to the intelligent contract, binds the commodity and the banknote to the user, feeds back and checks the activation state and the like at 5 stages, and packages the commodity and the banknote to form a first component. After the user obtains the commodity, the commodity information and the banknote crown word number are input for checking and activating, and the second assembly is formed by packaging. One merchant corresponds to a plurality of users, namely one first component corresponds to a plurality of second components.
For the merchant:
in the stage of deploying the anti-counterfeiting service, firstly, an intelligent contract is created. The transaction processing method of the intelligent contract comprises initialization, registration of the crown word number and activation of the transaction processing method; the contract is then deployed to a blockchain, which may be a private chain operated by the merchant itself or a federation chain operated in conjunction with other businesses, or a public chain.
In the stage of initializing the intelligent contract, the unique identifier of the commodity to be protected is used as the commodity information, and the intelligent contract needs to be initialized according to the commodity information. The reason for this is that the banknotes are not disposable items and can be recycled for reuse on other goods. Thus, a smart contract may be initialized for a certain type of commodity. Even if the same banknote crown word number is used for anti-counterfeiting, new intelligent contracts only need to be initialized for other commodities, namely different intelligent contracts are used for different commodities, and the fact that the same crown word number can be used in different contracts without conflict can be guaranteed.
In the registration stage of the crown word number, the crown word number registration transaction processing method of the intelligent contract associates the provided crown word number with the commodity unique identifier indicated by the intelligent contract and stores the association in the block chain.
When the commodity and the bank note are bound and delivered to a user, an anti-counterfeiting check entrance is provided at the same time. In the registration stage of the crown word number, when a block which is matched with the crown word number provided by the user and the unique commodity identification exists in the block chain, activating the crown word number and storing the activation state in the block chain; otherwise, the inactive state is still maintained, and the active state is fed back to the user.
For the user:
firstly, purchasing commodities and bank notes bound with the commodities from merchants; then, entering an anti-counterfeiting inspection entrance comprising a second component, submitting the unique commodity identification and the banknote crown word number to an intelligent contract for activating transaction processing, and activating the crown word number and storing an activated state in the block chain when a block matched with the received crown word number and the unique commodity identification exists in the block chain; otherwise, the state is still kept in the inactivated state, and the user obtains the anti-counterfeiting checking result.
In summary, based on the technical solution, a commodity anti-counterfeiting system based on a block chain can be formed, which includes a first component and a second component. Wherein the content of the first and second substances,
the first component creates an intelligent contract and deploys the intelligent contract to the block chain, the intelligent contract is initialized according to commodities, the crown word number of the bank note is registered, and the bank note and the commodities are bound and sold to a user; the second component is arranged at the authenticity checking inlet and submits the unique identification of the commodity and the crown word number of the bank note;
the first component receives the unique commodity identification and the banknote crown word number sent by the plurality of second components;
the first component sends the result of the activation transaction to the second component.
Example two

The method may comprise the steps of:
step 101: the first component constructs an intelligent contract and deploys the intelligent contract to the blockchain, and the transaction processing method of the intelligent contract at least comprises initialization, crown word number registration and crown word number activation. And deploying the written intelligent contracts to a block chain to obtain the addresses of all contract methods for registration and activation logic of the crown word numbers.
Optionally, the intelligent contract initialization transaction method includes initializing the intelligent contract with a unique identification of the good. The reason for this is that the banknotes are not disposable items and can be recycled for reuse on other goods. Thus, a smart contract may be initialized for a certain type of commodity. Even if the same banknote crown word number is used for anti-counterfeiting, new intelligent contracts only need to be initialized for other commodities, namely different intelligent contracts are used for different commodities, and the fact that the same crown word number can be used in different contracts without conflict can be guaranteed.
Optionally, the crown number registration transaction processing method of the intelligent contract includes: and associating the crown word number with the unique commodity identification and storing the crown word number in the block chain.
Optionally, the method for processing the activation transaction of the intelligent contract is shown in fig. 2, and includes:
step 121: receiving the crown word number and the commodity unique identification submitted by the second component;
step 122: when a block which is matched with the received crown word number and the unique commodity identification exists in the block chain, activating the crown word number and storing an activation state in the block chain; otherwise, the inactive state is maintained.
Step 102: selecting a commodity and initializing the intelligent contract to associate the commodity with the intelligent contract.
It should be understood that the identification that may uniquely represent the item may be used as information associated with the initiation of the smart contract for the item, including but not limited to bar codes, two-dimensional codes, etc.
Step 103: selecting a banknote and submitting the banknote crown word number to the smart contract for registration.
It should be understood that the banknote crown word number is registered for an intelligent contract initialized for a certain commodity to establish a corresponding relationship between the crown word number and the commodity, and the corresponding relationship may be that a certain type of commodity corresponds to a plurality of crown word numbers. Because the bank note is not a disposable article and can be recycled and reused on other commodities, the same bank note crown word number is used, and new intelligent contracts only need to be initialized for other commodities, namely different intelligent contracts are used for different commodities, so that the situation that even the same crown word number can be used in different contracts without conflict can be ensured.
Step 104: and binding and delivering the commodity and the bank note to a user so that the user invokes the intelligent contract to activate the bank note crown word number through a second component.
It should be understood that the second component should be placed in a merchant-provided anti-counterfeit pinging portal. The inspection entrance can be a mobile phone APP or a query website.
Step 105: and sending the activation state to the second component, updating the intelligent contract and storing the intelligent contract to the block chain.
Referring to fig. 3, a schematic step diagram of a merchandise anti-counterfeiting method provided in an embodiment of the present specification is shown, where an execution main body of the merchandise anti-counterfeiting method may be a user side, and is defined as a second component in the present specification; the second component is placed in a ping portal provided by the merchant. The method may comprise the steps of:
step 201: the second component obtains the unique identification of the commodity and the crown word number of the banknote;
step 202: calling an intelligent contract of a first component to activate transaction processing;
step 203: and receiving the result of the activated transaction returned by the first component.
According to the technical scheme, the crown word number of the banknote is used as the anti-counterfeiting marker, the crown word number is registered in the block chain by deploying the intelligent contract to perform anti-counterfeiting protection on the specific commodity, and meanwhile, the same crown word number can be repeatedly used on different commodities, so that the anti-counterfeiting effect of the commodity to be protected is effectively improved. The anti-counterfeiting implementation cost and difficulty are reduced.

In embodiments where an invoice is used as the carrier, the invoice code (or invoice number) is the unique code. The specific embodiment is as follows:
EXAMPLE six
The invoice code comprises an invoice code and an invoice number, and is a code given to the invoice by the tax department. When inquiring the authenticity of the invoice, the invoice code and the invoice number need to be input. For the invoice code, the common invoice code is 12 bits; the code of the value-added tax special invoice and the value-added tax common invoice is originally 10 bits, the value-added tax common invoice is adjusted in China from 1 month and 1 day in 2018, and the code of the new value-added tax common invoice (folded invoice) is adjusted from 10 bits to 12 bits. And the invoice number is typically 8 digits. The invoice code therefore has at least 18-20 digits.
The invoice code has the characteristics of strong anti-counterfeiting performance, one invoice with one number and large issuing amount, and in addition, the invoice code is easy to identify as an invoice anti-counterfeiting mark, and the invoice can be considered as a true invoice through the verification of a tax authority.
The block chain technology and the invoice code are used for anti-counterfeiting inspection of commodities, and 2 execution main bodies are involved, namely a merchant and a user. The merchant arranges intelligent contract anti-counterfeiting service, initializes intelligent contract, registers invoice code to intelligent contract, binds the commodity and the invoice to the user, and feeds back the checking activation state to form a first component. After the user obtains the commodity, the commodity information and the invoice code are input for checking and activating, and the second component is formed by packaging. One merchant corresponds to a plurality of users, namely one first component corresponds to a plurality of second components.
For the merchant:
in the stage of deploying the anti-counterfeiting service, firstly, an intelligent contract is created. The transaction processing method of the intelligent contract comprises initialization, registration of invoice codes and activation of the transaction processing method; the contract is then deployed to a blockchain, which may be a private chain operated by the merchant itself or a federation chain operated in conjunction with other businesses, or a public chain.
In the stage of initializing the intelligent contract, the unique identifier of the commodity to be protected is used as the commodity information, and the intelligent contract needs to be initialized according to the commodity information. The reason for this is that the invoice is not a disposable item and can be recycled for reuse on other goods. Thus, a smart contract may be initialized for a certain type of commodity. Even if the same invoice code is used for anti-counterfeiting, new intelligent contracts only need to be initialized for other commodities, namely different intelligent contracts are used for different commodities, and the fact that the same invoice code can be used in different contracts without conflict can be guaranteed.
In the stage of invoice code registration, the invoice code registration transaction processing method of the intelligent contract associates the provided invoice code with the commodity unique identifier indicated by the intelligent contract and stores the invoice code and the commodity unique identifier in the block chain.
When the goods and the invoice are bound and delivered to the user, an anti-counterfeiting check entrance is provided at the same time. In the invoice code registration stage, when a block which is matched with an invoice code and a commodity unique identifier provided by a user exists in a block chain, activating the invoice code and storing an activation state in the block chain; otherwise, the inactive state is still maintained, and the active state is fed back to the user.
For the user:
firstly, acquiring commodities and invoices bound with the commodities for sale from a merchant; then, entering an anti-counterfeiting checking entrance comprising a second component, submitting the commodity unique identifier and the invoice code to an intelligent contract for activating transaction processing, and activating the invoice code and storing an activation state in the block chain when a block matched with the received invoice code and the commodity unique identifier exists in the block chain; otherwise, the state is still kept in the inactivated state, and the user obtains the anti-counterfeiting checking result.
In summary, based on the technical solution, a commodity anti-counterfeiting system based on a block chain can be formed, which includes a first component and a second component. Wherein the content of the first and second substances,
the first component creates an intelligent contract and deploys the intelligent contract to the block chain, the intelligent contract is initialized according to commodities, an invoice code is registered, and the invoice and the commodities are bound and sold to a user; the second component is arranged at the authenticity checking inlet and submits the unique identification of the commodity and the invoice code;
the first component receives the unique commodity identification and the invoice code sent by the second components;
the first component sends the result of the activation transaction to the second component.
