In the present application, as shown in fig. 1, the blockchain system includes a plurality of blockchain nodes, and each blockchain node is a service node that deposits money for a user according to a target ticket. That is, each service node that deposits money for the user according to the target ticket is used as a block chain node to construct a block chain system. Each service node can pack the target bill of the node, the bill information of the target bill, the bill verification information of the target bill and the data information such as the operation information of other target bills into a block and upload the block to a block chain system. Other service nodes of the block chain system as block chain nodes can read data information of the blocks uploaded by each node from the system.
The application provides an information storage method based on bill information verification, which is applied to a hardware environment of the block chain system, namely the following financial loan platform adopts the block chain system. In one embodiment, as shown in fig. 2, the information storage method based on bill information verification includes:
and S100, acquiring bill information of the target bill.
In this embodiment, the target tickets are tickets provided by the user when financing. The financial paying platform can pay the user according to the target bill so that the user can conduct financing according to the target bill. The ticket information of the target ticket refers to information recorded in the ticket related to the target ticket. For example, the invoicing party issuing the target ticket, the date of the target ticket, the number of the target ticket, the label of the target ticket, the deposit amount corresponding to the target ticket, and the like. And the financial paying platform extracts the bill information of the target bill from the target bill.
S200, retrieving first bill verification information according to the bill information, and verifying the bill information through the first bill verification information; the first bill verification information is information which is determined by an internal system according to the bill information and is used for detecting whether the bill information is correct or not.
In this embodiment, after the financial deposit platform acquires the bill information of the target bill, the financial deposit platform further performs authenticity verification on the target bill. The platform system retrieves first bill verification information for verifying the bill information according to the bill information of the target bill. The first bill verification information is information which is determined by an internal system of the platform system according to the bill information and is used for detecting whether the bill information is correct or not. The first bill verification information in the internal system may be the first bill verification information determined by the internal system searching the bill information of the target bill item by item through a plurality of other system platforms in advance and performing matching of the information. The internal system searches and matches the bill information item by item through a plurality of other system platforms to determine the first bill verification information, thereby ensuring the accurate judgment of the authenticity, namely the validity, of each bill information of the target bill.
S300, after the bill information is verified, packaging the target bill, and transmitting the packaged target bill serving as uplink data to a block chain system for storage; the block chain system comprises a plurality of service nodes for paying out the user according to the target bill; each serving node serves as a block node of the blockchain system.
In this embodiment, after the financial deposit platform verifies the bill information of the target bill, if the bill information passes the verification, the target bill is packaged and placed in the block chain system. The blockchain system is a system including a plurality of service nodes for depositing money to users. Each serving node acts as a blockchain node in the blockchain system. Each blockchain node is blockchain connected by a blockchain technique to form the blockchain system. In the blockchain system, each blockchain link point can read the block information of the packed chain. However, each chunk link point cannot modify the uplink information, i.e. the information of the target ticket is not allowed to be modified. The data of the stored target bill is matched and stored by utilizing the non-tampering characteristic of the blockchain.
In an embodiment, after step S300, the method further includes: and any block node in the block chain system reads the target bill, second bill verification information is called from the block node according to the characteristic information in the target bill, bill number entries, bill date entries and bill amount in the target bill are verified through the second bill verification information, verification result information and the target bill are bound, packaged into a block and uploaded to the block chain system.
Specifically, the platform system verifies the target bill by using the internal system, and packs and puts the bill into the block chain. And the internal system verifies the target bill based on the retrieval data of other systems adopted at the previous stage. However, due to the confidentiality of the ticket information of the target ticket, the disclosure degree of the ticket information of the target ticket by other systems is not enough, the internal system verifies the target ticket based on the information provided by other systems, and a verification result may be wrong. Therefore, after the target bill is packaged and added into the blockchain system, any blockchain node in the blockchain system can perform re-verification on the target bill. As the block nodes in the block chain system belong to service nodes for financial loan, the financial information of the type of the target bill has more storage capacity and belongs to information storage which is not disclosed externally. At the moment, the block node of the block chain system verifies the target bill again, so that the accuracy of the target bill information can be ensured. The block node extracts feature information in the target bill, where the feature information may be identification information of the target bill, such as information identifying the target bill when the internal system of each block node uploads the target bill. And according to the characteristic information, the block node extracts corresponding second bill verification information from the node, and verifies the bill number entry, the bill date entry and the bill amount in the target bill through the second bill verification information.
The verification result information can be verification information that the target bill information belongs to or verification information that the target bill information is false information. And the block node binds the verification result information with the target bill, packages the verification result information into a block and uploads the block to the block chain system. When the block chain system is packaged and uploaded, the identity information of the node can be added to identify that the verification result information belongs to the verification result given by the node.
According to the information storage method and device based on bill information verification, the storage medium and the computer equipment, after the bill information of the target bill is obtained, the first bill verification information used for detecting whether the bill information is correct or not is determined through the internal system, and the bill information of the target bill is verified by utilizing the first bill verification information. And after the bill information of the target bill passes the verification, packaging the target bill as uplink data, and transmitting the uplink data into a block chain system formed by a plurality of service nodes for paying the user according to the target bill. Therefore, any service node for paying in the block chain system can obtain the verified target bill through the block chain system, the target bill does not need to be verified manually, and the efficiency of bill information verification for paying in is improved.
In one embodiment, the ticket information of the target ticket includes a ticket number, a ticket date, and a ticket amount of the target ticket. At this time, as shown in fig. 3, step S200 includes:
s210, determining the first bill verification information according to the bill number, the bill date and the bill amount of the target bill; the first bill verification information comprises a verification bill number, a verification bill date and a verification bill amount.
S220, respectively matching and verifying the bill number, the bill date and the bill amount of the target bill through the verification bill number, the verification bill date and the verification bill amount; and when the bill number, the bill date and the bill amount in the first bill verification information are successfully matched with the verification bill number, the verification bill date and the verification bill amount respectively, the verification is passed.
In this embodiment, the financial reimbursement platform may retrieve the first item verification information from the local internal system using any one or more of the item number, item date, and item amount of the target item as a key. And verifying the target bill based on the retrieved first bill verification information. The first bill verification information comprises a corresponding verification bill number, a verification bill date and a verification bill amount. And when the bill number, the bill date and the bill amount in the target bill are matched with the verification bill number, the verification bill date and the verification bill amount in the retrieved first bill verification information, the bill information verification of the target bill is passed. Otherwise, the bill information verification of the target bill is not passed.
Further, as shown in fig. 4, step S210 includes:
s211, confirming the bill item and the bill name of the target bill from the internal system according to the bill number, the bill date and the bill amount of the target bill; the bill entry comprises a bill number entry, a bill date entry and a bill amount entry.
S213, searching a plurality of bill items of the target bill from a plurality of external systems according to the bill name.
S215, matching the plurality of bill items according to the bill number item, the bill date item and the bill amount item, and taking the content with the highest matching success rate as the item content of the corresponding item.
S217, determining the first bill verification information according to the content of each entry.
Specifically, the internal system of the financial loan platform confirms the bill entry and the bill name of the target bill according to the bill number, the bill date and the bill amount of the target bill, and further can search out the enterprise unit issuing the target bill from the external system according to the bill name. Meanwhile, the bill number entry, the bill date entry and the bill amount entry when the enterprise unit makes the target bill can be searched. Of course, since the internal system cannot determine the validity of the business entity issuing the target ticket in the external system, there is a high possibility that there are multiple business entities issuing the target ticket or information related to multiple target tickets during the retrieval process. In this case, in order to obtain the valid first bill verification information, the internal system may match each of the bill number entry, the bill date entry, and the bill amount entry among the plurality of searched bill entries, and may set the content with the highest matching success probability as the corresponding entry content. Therefore, correct first bill verification information can be screened out, and fake first bill verification information is eliminated.
In this case, step S300 further includes: and after the bill information passes the verification, packaging the target bill and the first bill verification information, marking identification information, and transmitting the information serving as uplink data into a block chain system for storage.
Specifically, after the internal system confirms the first bill verification information, the first bill verification information and the target bill are simultaneously packaged and marked with identification information, and then the identification information is uploaded to the blockchain system. Here, the internal system simultaneously packages the first bill verification information into the blockchain system, so that each service node of the platform system inquires the first bill verification information and uses the first bill verification information to perform independent bill verification on the target bill. Therefore, subsequent verification errors caused by the last target bill verification error can be avoided, and the bill verification accuracy is improved.
In an embodiment, as shown in fig. 5, after step S300, the method further includes:
s400, when any block node in the block chain system carries out deposit operation based on the target bill, after confirming that the deposit operation is finished, carrying out downlink processing on the target bill.
In this embodiment, any blockchain node of the blockchain system, that is, any service node in the platform system that deposits money, can deposit money to the user holding the target ticket according to the target ticket. And when the block node confirms that the deposit is successful, performing downlink processing on the target bill. Specifically, after the target ticket is verified, the order of the target ticket is linked, and the user of any block node of the block chain system after linking can perform subsequent operations, such as financing operations. And after the financing operation is finished, the transaction is finished, and the target bill is subjected to downlink processing.
In one implementation of this embodiment, step S300 includes: and packaging the target bill and the user information using the target bill as the incoming chain information, and placing the packaged incoming chain information into the block chain system as the uplink chain information. At this time, step S400 includes: when any block node in the block chain system deposits money based on the target bill, verifying a bill to be verified submitted by a deposit object according to the target bill, verifying the identity of the deposit object according to user information of the target bill, when the bill to be verified is verified, performing deposit operation on any block node, and after the deposit operation is confirmed to be finished, performing unlinking on the target bill.
The information storage method based on bill information verification in the above embodiment verifies the target bill. Only verified target tickets can be put into the blockchain system. The block chain system comprises a plurality of financial loan service nodes, and each financial loan service node deposits money by reading a target bill in the block chain system. Therefore, the user can be prevented from financing false bills, cloned bills and expired bills, and the safety of the system is improved. In addition, the target bill is not required to be checked and recorded manually by an auditor, and the money depositing efficiency is improved.
The application also provides an information storage device based on bill information verification. As shown in fig. 6, the information storage device based on ticket information authentication includes an acquisition module 10, an authentication module 20, and a storage module 30.
The acquiring module 10 is used for acquiring the ticket information of the target ticket. In this embodiment, the target ticket is a ticket provided by the user when financing. The financial paying platform can pay the user according to the target bill so that the user can conduct financing according to the target bill. The ticket information of the target ticket refers to information recorded in the ticket related to the target ticket. For example, the invoicing party issuing the target ticket, the date of the target ticket, the number of the target ticket, the label of the target ticket, the deposit amount corresponding to the target ticket, and the like. And the financial paying platform extracts the bill information of the target bill from the target bill.
The verification module 20 is configured to retrieve first bill verification information according to the bill information, and verify the bill information through the first bill verification information; the first bill verification information is information which is determined by an internal system according to the bill information and is used for detecting whether the bill information is correct or not. In this embodiment, after the financial deposit platform acquires the bill information of the target bill, the financial deposit platform further performs authenticity verification on the target bill.
