The specific principle is described with reference to fig. 4 below, which is a flowchart of the method.
As shown in fig. 4, fig. 4 is a flowchart illustrating an embodiment of a blockchain-based information verification method according to the present invention, wherein the processor 13 of the blockchain-based information verification device 1 implements the following steps when executing the verification program 10 stored in the memory 12:
step S1, acquiring coding information of a first participant in a blockchain, after a second participant uploads the coding information of the second participant to the blockchain based on the coding information of the first participant, adopting a preset decoding algorithm to decode the coding information of the first participant and the coding information of the second participant, comparing and verifying the decoded coding information of the first participant and the decoded coding information of the second participant, and acquiring a comparison verification result after verification is passed;
firstly, the information of a first participant is encrypted by a coding and blockchain encryption technology and then stored in a blockchain, and the stored information is decrypted by a corresponding blockchain decryption technology to obtain the coding information of the first participant. The second party obtains the coding information of the first party from the block chain, obtains corresponding information after decoding, and uploads own information according to the information. The information of the second party is stored in the blockchain after being encrypted by the encoding and blockchain encryption technology. And then, comparing and verifying the information of the first participant and the second participant in the blockchain, specifically, firstly adopting a preset decoding algorithm to decode the encoded information of the first participant and the encoded information of the second participant, and then comparing and verifying after decoding.
Wherein the first party is, for example, the sponsor of the service and the second party is the sponsor of the service.
When performing the comparison verification, the comparison verification includes whether the field names (keys), the field values (values) and the like corresponding to the information of the two parties are respectively consistent, for example: verifying whether the product number, the product name (key), the specification (value), the code and the like are respectively consistent;
information decoded by the first party: 3ue8qikmd, single layer printed circuit board X280dx25edb;
information decoded by the second party: 3ue8qikmd, single layer printed circuit board X280dx25edb;
and through comparison verification, the information of the two parties is consistent, and the verification is passed.
The comparison verification result comprises information of comparison verification of the first party and the second party and information of verification passing. Of course, if the comparison verification of this time is not passed, a warning message is generated and fed back.
Step S2, after a first intermediate party uploads the coding information of the first intermediate party to a blockchain according to the participation sequence and based on the coding information of the second participant, the coding information of the first intermediate party is decoded by adopting the decoding algorithm, and the decoded coding information of the first intermediate party and the comparison verification result are subjected to recursion verification to obtain a first recursion verification result;
when the first party is the initiator of the service and the second party is the sponsor of the service, the first to nth intermediate parties can be the transacting party entrusted by the second party. According to the sequence of participation of the first to N-th intermediate parties, the first intermediate party acquires the coding information of the second party from the block chain, obtains corresponding information after decoding, and uploads own information according to the information. The information of the first intermediate party is stored in the blockchain after being encrypted by a blockchain encryption technology. And then, performing recursion verification on the first intermediate party and the verification result in the blockchain, specifically, decoding the encoded information of the first intermediate party by adopting the decoding algorithm, and performing recursion verification after decoding.
The recursive verification refers to the verification of the previous verification result and the current information, namely the verification of the verification result and the information, which is the recursive verification, but not the direct verification of the information and the information. The recursive verification has the advantages that the recursive verification actually comprises the information of the first intermediate party, the information of the first participator and the information of the second participator and the comparison verification result of the first participator and the second participator, so that the information verification is more accurate and reliable.
In the recursive verification, verifying whether the information in the comparison verification result is consistent with the field name (key), the field value (value) and the like corresponding to the information of the first intermediate party respectively is included. If the two are consistent, the verification is passed.
The first recursion verification result comprises the information of the comparison verification result, the information corresponding to the first intermediate party and used for recursion verification and the information of whether verification is passed or not.
And if the first recursion verification result is that the verification is not passed, generating a warning message and feeding back.
Step S3, performing mixed verification on the decoded encoded information of the first intermediate party and the decoded encoded information of the first participant and the decoded encoded information of the second participant respectively to obtain a first mixed verification result;
and S4, if the first recursion verification result or the first mixed verification result is that verification fails, generating a warning message and feeding back.
After the recursive verification, the decoded encoded information of the first intermediate party and the decoded encoded information of the first participant are separately verified, and the decoded encoded information of the first intermediate party and the decoded encoded information of the second participant are separately verified, that is, the mixed verification is performed, so as to further confirm whether the verification of the information is accurate and reliable.
The first mixed verification result comprises information for verifying the first intermediate party and the first participator, information for verifying whether the first intermediate party and the first participator pass or not, information for verifying the first intermediate party and the second participator and information for verifying whether the first intermediate party and the first participator pass or not.
If the first intermediate party and the first participant do not pass the verification, or the first intermediate party and the second participant do not pass the verification, namely the first mixed verification result is that the verification is not passed, a warning message is generated and fed back.
There may be one or more intermediaries. In one embodiment, when there are multiple intermediaries, i.e. including the first to (N-1) th intermediaries, the method further includes, after step S3, further steps of:
if the first recursion verification result and the first mixed verification result are verification passing, uploading the coding information of the Nth intermediate party to a blockchain according to the participation sequence and based on the coding information of the second participant in the Nth intermediate party, decoding the coding information of the Nth intermediate party by adopting the decoding algorithm, and recursion verifying the decoded coding information of the Nth intermediate party and the (N-1) recursion verification result to obtain an Nth recursion verification result, wherein N is an integer greater than or equal to 2;
the decoded coding information of the Nth intermediate party is respectively mixed with the decoded coding information of the first participant, the decoded coding information of the second participant and the decoded coding information of the first to (N-1) th intermediate parties to obtain an Nth mixed verification result;
and if the Nth recursion verification result or the Nth mixed verification result is that verification fails, generating a warning message and feeding back.
When each intermediate party uploads information according to the participation sequence and based on the coding information of the second participant, the information of each intermediate party is stored in a blockchain after being encrypted by coding and a blockchain encryption technology, the stored information is decrypted by using a corresponding blockchain decryption technology to obtain the coding information of each intermediate party, and then the information of each intermediate party is decoded to obtain the information of the intermediate party. And carrying out recursion verification on the information of the intermediate party and the last recursion verification result, and carrying out mixed verification on the information of the intermediate party and the information of the first participant, the second participant and the previous intermediate parties respectively. And if the recursive verification result or the mixed verification result is that the verification is not passed, generating a warning message and feeding back.
In the above embodiment, the blockchain encryption and decryption technique may be a hash algorithm or an asymmetric encryption and decryption algorithm. The predetermined decoding algorithm is a natural language based dummy code decryption algorithm. The information of the uploaded blockchain is subjected to dummy coding encryption by using a natural language idea to form an encryption dictionary base which belongs to the common multiple parties, so that the calculation speed can be improved, the data safety is improved, the blockchain encryption and decryption technology is adopted to encrypt and decrypt the information on the basis of the natural language dummy coding, and the information is stored in the blockchain, so that the judgment of the information is not interfered by the outside, and the safety and the accuracy of the information are completely ensured.
In other embodiments, on the basis of the above embodiments, the method further includes: and if the Nth recursion verification result and the Nth mixed verification result are verification passing, classifying the decoded encoded information of the first participant or the decoded encoded information of the second participant according to a plurality of classifying factors in a preset standard so as to classify the information with the same classifying factors into the same set and classify the information with different classifying factors into different sets.
The predetermined standards include national standards, industry standards, international standards, and a plurality of classifying factors in the predetermined standards are, for example, specification and model numbers of products, component contents, processing technology, actual use, sources and the like. If all the information passes verification, the information of the first party or the second party can be classified according to the standard, the information with the same classification factors is classified into the same set, and the information with different classification factors is classified into different sets.
The invention is illustrated by the following examples.
Taking a first party as a transaction initiator, a second party as a supply chain provider, and a middle party as a logistics related party as an example:
after the transaction initiator initiates the transaction, uploading own transaction information (including basic information of the transaction initiator, information of a supply chain provider, product information, purchase information, transaction mode information and the like) to a platform, encoding, encrypting by using a blockchain encryption technology and uploading to a blockchain;
the supply chain provider acquires the information of the transaction initiator from the blockchain, decrypts the information through the blockchain decryption technology and then decodes the information to obtain transaction information, then the supply chain provider selects a corresponding logistics related party, uploads the transaction information of the transaction initiator, the own basic information and the logistics related party information to the platform, encodes the transaction information, encrypts the transaction information through the blockchain encryption technology and uploads the encrypted transaction information to the blockchain. In the blockchain, comparing and verifying the transaction information uploaded by the transaction initiator and the information uploaded by the supply chain provider, and obtaining a comparison and verification result if the verification is passed;
according to the logistics sequence, the logistics related party acquires the information uploaded by the supply chain provider from the blockchain, decrypts the information by the blockchain decryption technology and then decodes the information to obtain the transaction information of the transaction initiator and the basic information of the supply chain provider, and then the logistics related party uploads the transaction information of the transaction initiator, the basic information of the supply chain provider and the logistics information to the platform for encoding, encrypts the information by the blockchain encryption technology and uploads the encrypted information to the blockchain. In the blockchain, recursion verification is carried out on the information uploaded by the logistics related party and the comparison verification result, and mixed verification is carried out on the information uploaded by the logistics related party, the transaction information of the transaction initiator, the information uploaded by the logistics related party and the information uploaded by the supply chain provider.
When there are N logistics related parties, the operations performed by the subsequent logistics related parties are similar to those performed by the logistics related parties, until all the information verification operations are performed.
