Abstract
A kind of application method of asymmetric encryption techniques on block chain is anti-fake, this method are the technologies using asymmetric encryption, block chain intelligence contract will be written after merchandise news and the data public key encryption that needs to encrypt.User verifies the true and false of commodity by chain query on private key, using the transparent, openly of block chain data, can not distort, so that the interests of producer, user are all preferably ensured.This method allows commodity to realize primary packaging, the process of opening in virtual digital world, and whole process is irreversible, is applied to the fields such as anti-fake, logistics, can be very good the authenticity for guaranteeing commodity.Operation of the present invention is simple, and implementation cost is low, economic benefit, and social benefit is huge.
Description
Technical field
The method of the present invention is related to the technical field of block chain and asymmetric encryption, specifically a kind of to utilize asymmetric encryption
Technology can not distort in conjunction with the data transparency, openly of block chain, by the process for encrypting and decrypting, allow commodity in virtual number
Primary packaging, the process of opening are realized in the word world, and whole process is irreversible.
Background technique
Under traditional mode, the method for anti-counterfeit of product has very much, and the method for fraud is also very much, how should prevent by not
Method molecule is faked, and also to prevent producer oneself from faking, and this method is the data transparency, openly using block chain, can not be distorted, can
To supervise well, due to can not distorting for data, to make a fake products, it is necessary to there is the key of a genuine article to be corresponding to it,
Considerably increase the difficulty of fraud.
Summary of the invention
Intelligent contract and asymmetric encryption techniques of the method for the present invention based on block chain, encryption, decryption are all recorded in area
On block chain, data are open and clear, can be applied to product false proof, and logistics express delivery is signed for, and concrete operations process is as follows:
1, block chain intelligence contract is built；
2, the member that block chain is added is authenticated, enterprise, the organization and individual only voluntarily to follow rules can just add
Enter；
4, member's typing merchandise news, generation public key and private key two dimensional code on block chain intelligence contract, will need anti-fake
The information such as commodity data and the data public key encryption that needs to encrypt after block chain is written；
5, when commodity need to verify, private key two dimensional code is scanned, inquires the information that this commodity records on block chain, and solve
Close encryption data, generates verifying record on block chain, and verifying terminates.
Specific embodiment
By taking application of the invention method on commodity counterfeit prevention as an example
1, production firm registers on block chain first, and carries out authentication, obtains the number label by certification
Name；
2, with asymmetric encryption techniques, a pair of of public key and private key is generated, anti-fake product information will be needed and need to encrypt
Data public key encryption after be written block chain intelligence contract in；
3, the corresponding private key of this public key two dimensional code is generated to be placed in packaging bag, wherein two dimensional code is covered with coat,
Or private key is placed in recesses；
4, after client enrollment registration, private key two dimensional code is scanned using special-purpose software, logs in publicly-owned chain query merchandise news, and
Ciphertext data, confirmation private key have not been used, and verifying terminates.
By taking application of the invention method in express delivery industry as an example
1, express company registers on block chain first, and carries out authentication, obtains the number label by certification
Name；
2, with asymmetric encryption techniques, a pair of of public key and private key is generated, public key, private key two dimensional code are printed on express delivery list
On, private key is covered with coat, and public key replaces the odd numbers of existing express delivery, all to want the information of typing express delivery odd numbers all in the past
To pass through scanning public key two dimensional code typing information, and block chain is written；
5, after client enrollment registration, express delivery list is signed for using special-purpose software scanning private key two dimensional code, after signing for, block chain will
Receipt information, including recipient are recorded, the time is signed for, signs for place etc..
