The embodiment of the present application provides a kind of invoice checking method based on block chain, is applied to above-mentioned invoice auditing system
In.This method can be executed by the invoice processing server in above-mentioned invoice auditing system.It as follows will be using the invoice as electronics
The invoice checking method based on block chain is described in detail for invoice.As shown in Fig. 2, the method includes
S201-S205:
S201, the invoice processing server obtain the first invoice information of invoice to be submitted an expense account.
It wherein, include the unique identification of the invoice to be submitted an expense account in first invoice information.Illustratively, described first
Invoice information is the invoice number and invoice codes of the invoice to be submitted an expense account.
Specifically, electronic invoice is uploaded in the invoice processing server by invoice reimbursement personnel, the invoice processing is flat
Image procossing and parsing are carried out to the electronic invoice according to the image information of electronic invoice in platform.Obtain the electronic invoice space of a whole page
All information.The first invoice information is extracted from all information of the electronic invoice space of a whole page.
It, can be with after the above-mentioned all information for obtaining the electronic invoice space of a whole page in a kind of implementation of this step
Verification first is carried out to the true and false of the invoice.Specifically:
Obtain the third invoice information of the invoice to be submitted an expense account；Wherein, the third invoice information for verify it is described to
Submit an expense account whether invoice is true invoice；The third invoice information is sent to the invoice validation platform；So that the invoice is tested
Card platform verifies the invoice to be submitted an expense account；Receive the invoice validation information that the invoice validation platform returns.It realizes
Automatic verifying to true from false of bills, is greatly saved the workload of auditor.
Illustratively, above-mentioned invoice validation platform can be Guo Shui Fa's ticket verification platform.The invoice processing server and state
Tax invoice validation platform establishes communication connection by network interface.Invoice processing server parses the content of electronic invoice
Later, by invoice number, invoice codes, the pre-tax amount of money, date of making out an invoice etc. are sent to national tax invoice verification platform and carry out verification, and
The verification result returned is received by network interface.
In a kind of implementation of this step, the invoice information of the invoice can also be stored in the block chain
In, specifically:
Obtain the second invoice information of the invoice to be submitted an expense account；Wherein, second invoice information is invoice audit
Equipment is to required information when submitting an expense account invoice and auditing；Second invoice information is written in the block chain,
And obtain the first block chain address；Wherein, the first block chain address is directed toward the second invoice information and is deposited in the block chain
The position of storage；The first block chain address is added to described wait submit an expense account in invoice.
Illustratively, the block chain address can be written in electronic invoice in the form that two dimensional code identifies, specifically:
The first block chain address is converted into two dimensional code mark；Two dimensional code mark is added to described wait submit an expense account in invoice.
Illustratively, second invoice information includes: invoice number, invoice codes, the pre-tax amount of money, make out an invoice date and Item Detail
Deng.
S202, the report for inquiring the invoice to be submitted an expense account in the block chain according to the unique identification of the invoice to be submitted an expense account
Write off record.
Wherein, the reimbursement record for all having submitted an expense account invoice is previously stored in the block chain.
Specifically, being previously written the reimbursement record for having submitted an expense account invoice in block chain.In the reimbursement record of the invoice
The timestamp of unique identification and invoice reimbursement including invoice, content etc..According to preset hash function or other modes,
The unique identification of the invoice is converted into corresponding Hash pointer.Invoice processing server gets the first of invoice to be submitted an expense account
It is after invoice information, the unique identification of the invoice to be submitted an expense account is raw according to above-mentioned preset hash function or other modes
At corresponding Hash pointer.The Hash pointer is the data block that may point to the Hash pointer equally comprising unique identification conversion.
Invoice processing server inquires the reimbursement record of invoice from the data block that the Hash pointer is directed toward.
If the reimbursement record of the invoice to be submitted an expense account is not recorded in S203, the block chain, it is determined that described wait submit an expense account hair
Ticket is not submitted an expense account.
Wherein, if there is no the data blocks for the Hash pointer converted comprising above-mentioned unique identification in block chain, then it represents that should
The reimbursement record for not recording the invoice in node, if there is the number for the Hash pointer converted comprising above-mentioned unique identification in block chain
According to block, then it represents that describe the reimbursement record of the invoice in the block chain.
In block chain technology, if what each node equated, only 51% or more node reaches common understanding it
Afterwards, the contents such as the reimbursement record of invoice or invoice information can be just written in block chain.
If each node is not equality, need to be calculated in final result according to the weighted value of each node to invoice
Reimbursement record or the node reached common understanding of invoice information shared by specific gravity whether more than 51%, go to judge whether invoice
The contents such as reimbursement record or invoice information are written in block chain.
Since each data block is connected at chain using the time as sequence in block chain, and packet in the latter data block (sub-block)
Include the Hash value field of father's block.If modifying to the data in father's block, in the data in father's block and block block
Father's block Hash value field will be inconsistent, causes block chain that father's block data is reported to malfunction.Therefore, the data one in block chain
Denier, which is written into, to be modified again.
Invoice to be submitted an expense account described in S204, label is not submit an expense account and be sent to the invoice to audit equipment, so that the invoice
Audit equipment is audited and is submitted an expense account to the invoice to be submitted an expense account.
Specifically, invoice processing server determines that the electronic invoice to be submitted an expense account is not submitted an expense account, then corresponding label is done in institute
It states on electronic invoice.After label is completed, which is returned into invoice audit equipment, so that the invoice audits equipment
The invoice to be submitted an expense account is audited and submitted an expense account.
In a kind of implementation of this step, which can also be participated in by reimbursement personnel and auditor, specifically:
After invoice processing server label completes the electronic invoice, which is sent to reimbursement personnel.Reimbursement
Personnel print the papery version of the electronic invoice, and carry out patch ticket, the operation such as record and submit corresponding contents (for example, patch ticket, is filled in
The related table that Finance Department issues, reimbursed sum, producing cause etc.), the labeled electronic invoice is sent to wealth later
Business personnel, or it is sent to audit equipment.Financial staff or invoice audit equipment are by adding on the scanning electron invoice space of a whole page
Two dimensional code mark transfers corresponding electronic invoice information from block chain, and is audited.After audit is completed, confirmation reimbursement,
And retain the papery reimbursement record of reimbursement personnel submission and the corresponding table submitted etc., inspection etc. of putting on record after giving over to uses.
In another implementation of this step, the first block chain address is the Hash Round Robin data partition of the invoice, is adopted
It is calculated with preset hash function or other computation rules.Then reimbursement record using identical hash function or other
The unique identification that computation rule calculates the invoice obtains the Hash Round Robin data partition of reimbursement record；The reimbursement record Hash Round Robin data partition with it is upper
State that the first block chain address is identical, the first block chain address can be directed toward the full layout information of invoice and the report of invoice simultaneously
Write off record.
The address is still convertible into two dimensional code mark and is added on the electronic edition of invoice to be submitted an expense account.Two dimensional code mark both may be used
To be the label that do not submit an expense account as invoice to be submitted an expense account, the address of invoice information storage location can also be used as.Invoice audits equipment
Two dimensional code mark, which need to only be scanned, can directly acquire the layout information of invoice and the reimbursement record of invoice.
S205, the reimbursement record for receiving the invoice to be submitted an expense account that the invoice audit equipment is sent；And by described wait report
The reimbursement record of pin invoice is written in the block chain.
