First, an application scenario to which the present application is applicable will be described. The method and the device can be applied to the technical field of transaction query. Research shows that when a user holding a credit card is suspicious of a certain transaction and wants to inquire specific transaction information of the transaction, the card issuer of the credit card is required to access through the card organization platform, the card organization platform forwards the information to an acquirer where a POS machine is located, and the acquirer replies an information certificate of the transaction and detailed transaction information to the user, so that the inquiry process is complicated, the time is long, and the inquiry efficiency is low.
In the prior art, the query process of the user box for querying the transaction information may specifically be:
the inquiry request of a user is sent to a card issuing bank of the credit card, the card issuing bank sends inquiry information in the inquiry request to a card organization platform for access, the card organization platform forwards the information to a receiving bank where the POS machine is located, the receiving bank uploads the inquired transaction information to the card organization platform, and the card organization platform returns the corresponding transaction information to the user through the card issuing bank of the credit card again, namely, the inquiry process is realized by multiple interactions of the card issuing bank, the card organization platform and the receiving bank of the credit card.
Based on this, the embodiment of the application provides a transaction information query method and device based on a block chain, and an electronic device, which realize simplification of a process for querying target transaction information, enable a query process of a user to be more convenient and faster, and provide query efficiency while shortening query time.
Referring to fig. 1, fig. 1 is a flowchart illustrating a transaction information query method based on a blockchain according to an embodiment of the present disclosure. As shown in fig. 1, the method for querying transaction information based on a blockchain according to an embodiment of the present application includes:
s101, receiving a query request of a target card issuing bank end for a target transaction task; the query request comprises basic transaction information, and the basic transaction information comprises information of a target card number.
In this step, when a user suspects a certain transaction task, a query request for the target transaction task may be sent to a target card issuing terminal corresponding to a credit card used by the user, and the target card issuing terminal sends the query request for the target transaction task to a block chain in which target transaction information corresponding to the query request is stored.
Here, the query request of the target transaction task includes basic transaction information, and the basic transaction information includes, but is not limited to, a first institution number of the target card issuing bank, target card number information, amount information of the target transaction, transaction date of the target transaction, authorization code of the target transaction, and transaction code of the target transaction.
And S102, determining transaction identification information according to the basic transaction information after determining that the target card issuing bank has the access authority.
In this step, after the block link receives the query request corresponding to the target transaction task, the block chain may first verify whether the target card issuing bank is registered, that is, whether the target card issuing bank has its own access right on the block chain, and after determining that the target card issuing bank has the access right, encrypt the basic transaction information according to a preset hash function in the block chain, and determine the transaction identification information corresponding to the basic transaction information.
Here, the transaction identification information may be, but is not limited to, a hash value, which is a character string for fixing data according to a fixed number and format.
Further, the basic transaction information further includes a first institution number of a target card issuing bank, public key information of the target card issuing bank, and private key information of the target card issuing bank, and it is determined that the target card issuing bank in step S102 has an access right through the following substeps:
and a substep 1021, determining whether the first organization number exists in a preset bank authority mapping table or not according to the first organization number of the target card issuing bank end.
In this step, whether the target card issuing bank is registered in the blockchain is judged through a first institution number corresponding to the target card issuing bank and used for representing the unique identifier of the target card issuing bank, that is, whether the first institution number exists in a preset bank authority mapping table of the blockchain can be determined.
And a substep 1022, if yes, performing authority authentication of the target card issuing terminal according to the public key information of the target card issuing terminal and the private key of the target card issuing terminal.
In this step, after it is determined that the target card issuing bank end is registered in the block chain, the authority of the target card issuing bank end on the block chain needs to be logged in by using the public key information of the target card issuing bank end and the private key of the target card issuing bank end, and if the public key information of the target card issuing bank end and the private key of the target card issuing bank end input to the block chain are correct, it is determined that the authority authentication or login of the target card issuing bank end on the block chain is successful.
And a substep 1023 of determining that the target card issuing bank end has the access right after the authentication is successful.
In this step, the authority of the target card issuing bank end on the block chain is authenticated and successfully logged in, that is, the target card issuing bank end is determined to have the access authority for inquiry and call.
S103, judging whether target identification information matched with the transaction identification information exists or not; the target identification information is information after signature decryption.
In the step, after the target issuing bank end is determined to have the access authority, the transaction identification information is signed and decrypted according to the preset specification convention of the distributed file system in the block chain, and whether the target identification information matched with the transaction identification information exists or not is judged after analysis.
Here, the distributed File System (IPFS) is a content-addressable peer-to-peer distributed File System, and the IPFS employs a content-address addressing technique, i.e., retrieval is performed through the content of a File rather than through the network address of the File. In short, since the hash operation is performed on the file content and the hash value is stored as the file name in the local database, the file name remains unchanged as long as the file content remains unchanged.
And S104, if the target transaction information exists, determining a target storage address corresponding to the target identification information, calling the stored target transaction information matched with the target identification information through the target storage address, and sending the target transaction information to the target card issuing bank.
In the step, in the determination of the existence of the target identification information matched with the transaction identification information, based on the content addressing function of the IPFS in the block chain, a target storage address corresponding to the target identification information is determined, the target transaction information matched with the target identification information is obtained through the target storage address, and the target transaction information is sent to the user through the target issuing bank for the user to inquire.
Here, the target identification information includes, but is not limited to, basic transaction information, time of the target transaction, location of the target transaction, address of the transaction user, name of the transaction user, number of the target pos, and the like.
Further, the target transaction information in step S104 is stored by the following sub-steps:
and in the substep 1041, determining whether the second organization number exists in a preset bank authority mapping table according to the second organization number of the target order receiving line terminal.
In this step, whether the target acquirer end is registered in the blockchain is determined by a second mechanism number corresponding to the target acquirer end and used for representing the unique identifier of the target acquirer end, that is, whether the second mechanism number exists in a preset bank authority mapping table of the blockchain is determined.
And 1042, if so, performing authority authentication of the target order receiving line end according to a private key of the target order receiving line end.
In this step, after it is determined that the target order receiving line terminal is registered in the blockchain, the authority of the target order receiving line terminal on the blockchain needs to be logged in by using the private key of the target order receiving line terminal, and if the private key of the target order receiving line terminal input to the blockchain is correct, it is determined that the authority authentication or login of the target order receiving line terminal on the blockchain is successful.
In the above, the IPFS in the block chain specifically uses a self-authentication file system to authenticate the authority of the target acquirer.
And a substep 1043, after the authentication is successful, determining that the target acquirer end has the access right.
In this step, the authority authentication of the target acquirer bank on the blockchain is successful, that is, it is determined that the target acquirer bank has the access authority for storage and invocation.
And a substep 1044 of receiving a storage request of the target acquirer to the standard transaction information generated by the target acquirer for the target transaction, wherein the standard transaction information is obtained by packaging the transaction certificate information and the user information by the target acquirer.
In the step, on the premise that the target acquirer end is determined to have the intervention right or pass the verification, the target acquirer firstly encapsulates transaction certificate information and user information which are generated on a POS machine of a user and are related to the target transaction, generates standard transaction information which corresponds to the target transaction, sends the standard transaction information to a block chain, and receives a storage request of the standard transaction information generated by the target acquirer end to the target transaction by the block chain.
Here, the user information includes POS base number information of the user, business license information of the user, organization structure code of the user, and the like.
And substep 1045, based on the storage request, performing hash encryption on the standard transaction information, and after encryption, using a private key of the target transaction receipt end to perform signature to determine target transaction information.
In the step, in the process of performing hash encryption on the standard transaction information according to the storage request, a specific hash algorithm formula is as follows:
y＝HASH(x)；
here, x is used to characterize the transaction data of the target card.
After the Hash encryption, a private key of a target order receiving end is used for signing to obtain target transaction information.
In this way, the target transaction information can be prevented from being tampered by using the private key of the target receipt bank for signature; and on the other hand, the private key of the target card-issuing bank end is used for signing, so that the target card-issuing bank end with the private key can look up transaction information data, and the subsequent target card-issuing bank end can conveniently inquire the target transaction information.
Substep 1046, performing contractual processing on the target transaction information, and storing the processed target transaction information.
In this step, the performing of contractual processing on the target transaction information in sub-step 1046, and storing the processed target transaction information includes:
contract information associated with the target transaction information is obtained.
Here, intelligent contract information is composed according to the target transaction information and the IPFS public chain, and contract information associated with the target transaction information is determined.
The contract information treasury is not limited to the card information of the target card, the name of the holder of the target card, the card number of the target card, the consumption time of the transaction, the consumption amount of the transaction, the consumption certificate of the transaction and the related information of the POS machine.
And block packaging is carried out on the contract information and the target transaction information, and the packaged target transaction information is sent to all slave nodes by a public link node so as to store the target transaction information in all the slave nodes.
After the contract information is determined, firstly broadcasting the contract information to the whole block chain through an IPFS (internet protocol file system) public chain node, then waiting for the nodes to pack the contract information and the target transaction information in blocks, and after the block packing is completed, sending the packed target transaction information to all slave nodes from the public chain node, completing the uploading of the target transaction information in the block chain, so that all the slave nodes can store the target transaction information.
