When making out an invoice, interface as shown in Figure 1B is shown in the invoice issuing system for unit of making out an invoice.It opens at left side interface Ticket people, drawer's Taxpayer Identification Number, invoice codes, invoice number, using rule, address, phone, bank of deposit and account be hair It is good that ticket issues system Auto-writing, wherein can be in the range of the invoice number shown in figure 1A for the unit granting of making out an invoice Middle sequence chooses the invoice number Auto-writing that do not provide at left side interface, such as selects according to the ascending sequence of invoice number It takes.Information in the interface of right side, which needs to make out an invoice when the responsible employee to make out an invoice of unit makes out an invoice, fills in, mainly have invoice new line title, Invoice new line Taxpayer Identification Number, receiptor, receiptor's phone, address, phone, bank of deposit and account, the amount of money, purposes etc..It fills out After writing, employee's point " confirmation " button for unit of making out an invoice.Invoice issuing system is outputed according to the information filled on interface and is made out an invoice The electronic invoice that unit is outputed, these electronic invoices, which by wechat described below the modes such as scan and are transferred to receiptor, (to be sent out Ticket reimbursement unit employee) card packet in.Meanwhile the behavior that this is made out an invoice of invoice issuing system is as an event of making out an invoice, Be recorded on block chain, the event block made out an invoice as one, in the block record just like Figure 1B invoice information filled in and Event of making out an invoice invoice transinformation.Invoice transinformation includes the side's of producing information of invoice, the side's of being transferred to information, transfer time.In In event of making out an invoice, the side of producing is unit of making out an invoice, " green field Co., Ltd, Shenzhen " as shown in Figure 1B, the side of the being transferred to person of being Work, as shown in Figure 1B " Zhang Xin ", transfer time is to start the time made out an invoice after clicking Figure 1B " confirmation " button, this when Between be self registering by invoice issuing system.

In fig. ib, after employee's point " confirmation " button for unit of making out an invoice, occurs two dimensional code shown in Fig. 1 C on interface. Oneself mobile phone of employee, i.e., after employee's terminal 102 scans the two dimensional code, electronic invoice can be automatically credited employee's mobile phone, such as There are in the wechat card packet of mobile phone.

After two dimensional code of the employee in mobile phone scanning figure 1C, occurs prompt " your successful scan on the interface of Fig. 1 D Two dimensional code, electronic invoice have been stored in the Ka Bao " of wechat.

After employee sees the interface of Fig. 1 D, open wechat, touch " I " option in the lower right corner, occur on screen " wallet ", The options such as " collection ", " photograph album ", " Ka Bao ", as referring to figure 1E.

Employee selects " Ka Bao " option shown on Fig. 1 E, interface shown in Fig. 1 F occurs.Employee is listed on the interface Card packet in content, including " card ", " discount coupon of friend ", " my ticket " etc..Electronic invoice is at " my ticket " In.

Employee selects " my ticket " on the interface shown in Fig. 1 F, shows that is stored on employee's mobile phone owns on screen Ticket is identified with invoice and is distinguished wherein there is three invoices, and invoice mark is made of invoice codes-invoice number, such as Fig. 1 G institute Show.

Employee selects the invoice shown on the interface of Fig. 1 G, occurs interface as shown in fig. 1H on screen.The interface On list the Action option that can be carried out to the invoice, including " browsing ", " printing ", " being sent to "." printing " option is generally used for Electronic invoice is printed as the case where submitting an expense account under paper line." being sent to " option is generally used for sending expense report for electronic invoice The case where in the terminal of position to carry out electronic invoice reimbursement." browsing " option, which is for general on, to be printed as paper or is sent to report The invoice is checked before pin unit.

Employee inputs the registration I D of reimbursement unit terminal on the interface shown in Fig. 1 H, send reimbursement for electronic invoice Unit terminal reimbursement.At this moment, on the screen of reimbursement unit terminal, interface as shown in Figure 1 I is automatically generated.The showing interface Information include invoice information and make out an invoice event invoice transinformation.Wherein, invoice information is that basis passes to reimbursement unit terminal Electronic invoice on Automatic generation of information, it is basically the same with the information in Figure 1B.And event invoice of making out an invoice turns Moving information then is the invoice reimbursement system automatically generated for submitting an expense account unit terminal.It includes the side's of producing information, the side's of being transferred to information, turns The side's of entering phone, transfer time (not shown) etc., wherein the side's of producing information is generated according to drawer's information in invoice information, with Drawer's information is consistent, such as " green field Co., Ltd, Shenzhen " in Figure 1B；The side's of being transferred to information is believed according to invoice What receiptor's information in breath generated, it is consistent with receiptor's information, such as " Zhang Xin " in Figure 1B；The side's of being transferred to phone is according to hair What receiptor's phone in ticket information generated, such as " 13550422355 " in Figure 1B.

The financial staff of reimbursement unit audits the interface of Fig. 1 I, it is believed that after errorless, need to check this invoice whether be Whether false and this invoice is to repeat situations such as submitting an expense account, but submit an expense account unit itself and not can be carried out this inspection, need by Request is sent to block chain managing bill system 4, and block chain managing bill system 4 is allowed to carry out this inspection, then will check and ties Fruit returns to reimbursement unit terminal, decides whether or not to submit an expense account this invoice to submit an expense account the financial staff of unit.At this moment, expense report The financial staff of position selects " sending invoice reimbursement request " button at the interface Fig. 1 I, in this way, reimbursement unit terminal is sent out to block chain Ticket management system 4 sends invoice reimbursement request, contains information as shown in Figure 1 I in the invoice reimbursement request.Block chain hair Ticket management system 4, which starts to submit an expense account the invoice, to be requested to audit, and determines whether to submit an expense account.

After the financial staff of reimbursement unit selects " the sending invoice reimbursement request " of Fig. 1 I, there is the interface of Fig. 1 J.It should Display " platform is auditing your invoice reimbursement request, please bear with " in interface.

When block chain managing bill system 4 audits the invoice, production when making out an invoice of the invoice stored in block chain is searched Invoice information, event of making out an invoice invoice transinformation in raw event block.If invoice is submitted an expense account the invoice information in requesting, is opened Ticket event invoice transinformation in the event block generated when making out an invoice of the invoice stored in block chain invoice information, Event of making out an invoice invoice transinformation is inconsistent, then the invoice is invoice distort or false.At this point, showing as shown in figure iK Interface is shown " your invoice information is not inconsistent with the invoice information put on record, therefore has tampering, and the audit fails ".

If the invoice information, event of making out an invoice invoice transinformation in invoice reimbursement request are somebody's turn to do with what is stored in block chain Invoice information, event of making out an invoice invoice transinformation in the event block of invoice generated when making out an invoice is consistent, then the invoice is not Invoice distort or false.In one embodiment of the present disclosure, also to verify whether the invoice is the invoice for repeating reimbursement. Due to after invoice is submitted an expense account, the case where for submitting an expense account on line, after completing primary reimbursement, invoice is as a kind of assets, by institute It has the right to go to reimbursement unit from employee, at this point, not being if block chain managing bill system 4 checks the current invoice owner The employee of reimbursement, it is likely that illustrate that the invoice had submitted an expense account the transfer for once having been completed ownership, at this point, also not permitting Perhaps invoice is submitted an expense account.The case where for submitting an expense account under line, may inquire to block chain managing bill system 4 when reimbursement unit is submitted an expense account be It is no the invoice to be submitted an expense account, but after submitting an expense account due to the reimbursement unit not on line, be indifferent to and be also not desired to whereabouts block chain hair Ticket management system 4 goes to implement the transfer of the invoice ownership.Therefore, in the case where online lower reimbursement, in the embodiment of the present disclosure, Electronic invoice is just being printed to the link for reimbursement, lock state is arranged to invoice.In the locked state, only allow to report Pin is primary.It is in the lock state if it is invoice and second is requested reimbursement, in this case, do not allow for submitting an expense account the hair Ticket.In this way, it is prevented that repeating to submit an expense account.Therefore, the risk of invoice reimbursement is greatly reduced.Fig. 1 L shows display " your hair Ticket information had been submitted an expense account, therefore the audit fails " interface.

Since the embodiment of the present disclosure had not only prevented the reimbursement of false invoice, but also repetition is prevented to submit an expense account, if verified both Without the reimbursement of false invoice, also it is not related to repeating to submit an expense account, then allows to submit an expense account, show interface shown in Fig. 1 M at this time, display is " flat Platform has audited the invoice reimbursement request by you, if needs to complete invoice transfer ".

The financial staff interface shown in Fig. 1 M for submitting an expense account unit selects "Yes", occurs invoice information and reimbursement event at this time The confirmation page of invoice transinformation, such as Fig. 1 N.Invoice information in the interface is to send according to employee to reimbursement unit terminal Electronic invoice in Automatic generation of information, correspond essentially to the invoice information in interface shown in Fig. 1 I.In the interface Reimbursement event invoice transinformation include the side's of producing information, the side's of being transferred to information, the side's of producing phone etc..The side's of producing information be according to For receiptor's information in invoice information come what is generated, the side's of being transferred to information is generated according to the invoice new line title in invoice information , the side's of producing phone is generated according to receiptor's phone in invoice information.

The financial staff of reimbursement unit verify the information it is errorless after, select " send reimbursement invoice transfer request " in Fig. 1 N Button sends reimbursement invoice transfer request to block chain managing bill system 4.The reimbursement invoice transfer request includes invoice letter Breath, reimbursement event invoice transinformation.Block chain managing bill system 4 believes the invoice information, reimbursement event invoice transfer It ceases as the event block for submitting an expense account the invoice, is recorded on block chain.In this way, be achieved that the ownership of invoice from employee to The transfer for submitting an expense account unit shows the interface of " being successfully completed invoice transfer " to the financial staff of reimbursement unit, as shown in Fig. 1 O.

If employee selects " printing " submit an expense account under line in the processing selection interface of invoice as shown in fig. 1H, such as The terminal of fruit employee at this time shows " please connect data line to print to printer ", as shown in Figure 2 A.Meanwhile it being sent out to block chain Ticket management system 4 sends print request under invoice line, and the invoice is recorded as lock state by block chain managing bill system 4. The characteristics of lock state be only allow it is primary to the invoice reimbursement being in the lock state, in other words, from the terminal of reimbursement unit to Block chain managing bill system 4 sends invoice reimbursement request once, not submits an expense account more than primary, thus reimbursement under realizing online In the case where avoid repeat submit an expense account purpose.

Assuming that terminal is connected to printer by connecting line by employee, selected on the interface shown in Fig. 2A " it has connected, Start to print ", at this moment printer starts to print electronic invoice.There is a two dimensional code on the invoice printed, represents block chain The block main body digest value of the event block for outputing the invoice of upper record, the digest value are equivalent to the thing for outputing the invoice The mark of part block is that uniquely, can be found by it and output the invoice for the event block for outputing the invoice Event block.

When online lower reimbursement, employee is taken the electronic invoice printed at the financial staff of reimbursement unit.Financial staff " reimbursement " is selected in invoice reimbursement system, interface shown in Fig. 2 B occurs, display " please needs to submit an expense account with the scanner scanning of connection Two dimensional code on invoice ".At this moment, financial staff's scanner scanning two dimensional code identifies the event block for outputing the invoice The block main body digest value.

Then, in the interface of Fig. 2 C, the financial staff for submitting an expense account unit fills in invoice information, event of making out an invoice invoice transfer letter Breath.Invoice information is according to the information solicitation on the invoice printed, and event of making out an invoice invoice transinformation produces people's information It is according to drawer's information solicitation in the invoice printed, the side's of being transferred to information is according to the receiptor in the invoice printed Information solicitation, the side's of being transferred to phone is filled according to receiptor's phone in the invoice printed.Then financial staff selects " sending invoice reimbursement request " on interface sends invoice reimbursement request, the invoice reimbursement to block chain managing bill system 4 Request includes the block main body digest value scanned the two-dimensional code, the invoice information filled on the interface of Fig. 2 C, event of making out an invoice Invoice transinformation.

Then, reimbursement unit terminal shows interface as shown in Figure 2 D, and " the invoice reimbursement that platform is auditing you is asked for display It asks, please bear with ".

If block chain managing bill system 4 finds that invoice submits an expense account the invoice information in request, the transfer of event of making out an invoice invoice Information turns with the invoice information in the event block of the invoice stored in block chain generated when making out an invoice, event of making out an invoice invoice Shifting information is inconsistent, then the invoice is invoice distort or false.At this point, the interface that display is as shown in Figure 2 E, display " you Invoice information is not inconsistent with the invoice information put on record, therefore has tampering, and the audit fails ".

If the invoice information, event of making out an invoice invoice transinformation in invoice reimbursement request are somebody's turn to do with what is stored in block chain Invoice information, event of making out an invoice invoice transinformation in the event block of invoice generated when making out an invoice is consistent, then the invoice is not Invoice distort or false.In one embodiment of the present disclosure, also to verify whether the invoice is the invoice for repeating reimbursement. Verify whether that the method for repeating to submit an expense account may include whether the owner for judging that invoice is current is the employee (receiptor of invoice), Though and judging whether the invoice is in unlocked state or to be in the lock state but request reimbursement for the first time.If invoice The current owner is the employee, though and the invoice be in unlocked state or be in the lock state for the first time request Reimbursement is not then to repeat to submit an expense account.If the current owner of invoice is not the employee or the invoice is in the lock state and not It is request reimbursement for the first time, then is to repeat to submit an expense account, shows the boundary of " your invoice information had been submitted an expense account, therefore the audit fails " Face, as shown in Figure 2 F.

If verified both without the reimbursement of false invoice, also it is not related to repeating to submit an expense account, then allows to submit an expense account, show figure at this time Interface shown in 2G, display " platform has audited the invoice reimbursement request by you ".

As shown in figure 4, according to one embodiment of the disclosure, the information processing method in a kind of invoice reimbursement is provided. This method is executed by block chain gateway server (such as block chain gateway server 401 in Fig. 3 A).This method comprises:

Step 410 receives invoice reimbursement request, and the invoice reimbursement request outputs the hair comprising what is recorded on block chain Mark, invoice information, event of the making out an invoice invoice transinformation of the event block of ticket；

Step 420, according to the mark of the event block for outputing the invoice, search opening of recording on the block chain The event block of the invoice out；

Step 430, the invoice information in the event block found, event of making out an invoice invoice transinformation respectively with it is described When invoice submits an expense account the invoice information and consistent event invoice transinformation of making out an invoice in request, sending allows the invoice to submit an expense account Response.

These steps are described in detail separately below.

In step 410, invoice reimbursement request is received, the invoice reimbursement request outputs institute comprising what is recorded on block chain State the mark, invoice information, event of making out an invoice invoice transinformation of the event block of invoice.

Invoice reimbursement request be invoice reimbursement unit terminal 101 is sent to block chain gateway server 401 be used for verify The request whether invoice can be submitted an expense account.

In the application scenarios submitted an expense account on invoice line, invoice reimbursement request is in response to scheming in the financial staff of reimbursement unit Selection " send invoice reimbursement request " on the interface of 1I and send.

The mark of event block is to discriminate between unique symbol of event block, and the mark of different event blocks is different.

In one embodiment, the mark of event block is to carry out abstract operation to the block main body of event block and obtain Digest value.Output the event block of the invoice mark be exactly to the block main body of the event block for outputing the invoice into Digest value obtained from row abstract operation.It, should since the digest value that different character strings obtains after operation of making a summary is different Digest value can be as the mark of event block.

In another embodiment, the mark of event block is to carry out abstract obtained from abstract operation to event block Value carries out digest value obtained from abstract operation to the whole event block for including block head and block main body.It outputs described The mark of the event block of invoice is exactly to pluck to the event block (including block main body and block head) for outputing the invoice Want digest value obtained from operation.

In another embodiment, the mark of event block is height of the event block on block chain.Output the hair The mark of the event block of ticket is the height for outputing the event block of the invoice on block chain.It is understood that event The mark of block can also obtain by other means, and the embodiment of the present invention does not limit this.

Invoice information is the invoice information in Fig. 1 I, and event of making out an invoice invoice transinformation is such as the event hair of making out an invoice in Fig. 1 I Ticket transinformation.Invoice information is read in the electronic invoice for be forwarded to invoice reimbursement unit terminal 101 from employee's terminal 102, And verified by the financial staff of invoice reimbursement unit.Electronic invoice is placed on the Ka Bao of employee's terminal 102 by terminal of making out an invoice 201 In, contain invoice information in the electronic invoice.If employee does not distort but is forwarded directly to invoice reimbursement unit terminal 101, invoice information can be directly read from the electronic invoice.Event of making out an invoice invoice transinformation is then reimbursement unit terminal Invoice reimbursement system automatically generated.It includes the side's of producing information, the side's of being transferred to information, the side's of being transferred to phone etc., wherein the side of producing Information is generated according to drawer's information in invoice information, consistent with drawer's information；The side's of being transferred to information is according to hair What receiptor's information in ticket information generated, it is consistent with receiptor's information；The side's of being transferred to phone is according to getting in invoice information What people's phone generated.The block main body digest value for outputing the event block of the invoice is to make out an invoice in terminal 201 of making out an invoice to reimbursement What member's utilization of hour digest algorithm (such as hash algorithm etc.) of unit generated, it is that event block is different from other event blocks , mark that represent the event block.The block main body digest value can be printed directly on electronic invoice, in this way, reimbursement unit Terminal 101 can directly read the block main body digest value and be placed in invoice reimbursement request.The block main body digest value can also It is imprinted on electronic invoice with being converted to two dimensional code.In this way, electronic invoice is transmitted in reimbursement unit terminal 101, unit is submitted an expense account The block main body digest value that two dimensional code represents is placed on invoice reimbursement by the two dimensional code on 101 automatic identification electronic invoice of terminal Block chain gateway server 401 is sent in request.

In the application scenarios submitted an expense account under invoice line, invoice reimbursement request is in response to scheming in the financial staff of reimbursement unit Selection " send invoice reimbursement request " on the interface of 2C and send.Invoice information and event invoice transinformation of making out an invoice are Fig. 2 C The information that middle financial staff fills according to the invoice information printed.Event of making out an invoice invoice transinformation includes the side's of producing letter It ceases, the side's of being transferred to information, the side's of being transferred to phone etc., wherein the side's of producing information is generated according to drawer's information in the invoice printed , it is consistent with drawer's information；The side's of being transferred to information is generated according to receiptor's information in the invoice printed, and is got People's information is consistent；The side's of being transferred to phone is generated according to receiptor's phone in the invoice printed.Output the thing of the invoice The block main body digest value of part block be terminal 201 of making out an invoice make out an invoice unit to reimbursement member's utilization of hour digest algorithm (such as Hash algorithm etc.) generate, it is the mark that event block is different from other event blocks, represents the event block.The area Block main body digest value is also translated into two dimensional code and is imprinted on electronic invoice.In this way, after employee prints the electronic invoice, the two dimensional code It is just imprinted on the invoice printed.As shown in Figure 2 B, the financial staff for submitting an expense account unit is with two on scanner scanning printed invoice After tieing up code, the two dimensional code on 101 automatic identification electronic invoice of unit terminal is submitted an expense account, the block main body that two dimensional code is represented is made a summary Value is placed in invoice reimbursement request and is sent to block chain gateway server 401.

At step 420, it according to the mark of the event block for outputing the invoice, searches and is recorded on the block chain The event block for outputing the invoice.

As described above, the event block that the mark for outputing the event block of the invoice is the invoicing be different from it is other The symbol of event block, therefore, block chain gateway server 401 can find outputing of recording on block chain according to the mark The event block of the invoice.

Specifically, when the mark of the event block for outputing the invoice is to output the area of the event block of the invoice When block main body digest value, the block main body digest value of the event block for outputing the invoice is to comprising invoice information and opening The block main body of ticket event invoice transinformation carries out what abstract operation generated.One example of the abstract operation is Hash fortune It calculates.In the link for outputing the invoice, increase the event block of an invoicing on block chain.The event block includes area Build and block main body.By the invoice information, event of making out an invoice invoice transinformation, as the event for outputing the invoice At least part of the block main body of block is recorded on block chain.The block main body can also include other parts, such as report Pin terminal signing messages, remark information when generating the block etc..In one embodiment, calculated described to output the hair The digest value of the block main body of the event block of ticket and with the event for outputing the invoice is not recorded on the block chain The digest value of the last one block before block, at least one of the block head as the event block for outputing the invoice Part.The block head can also include other parts, such as parity check code etc..In another embodiment, calculated The digest value of the block main body of the event block for outputing the invoice and with described output is not recorded on the block chain The digest value of the block main body of the last one block before the event block of the invoice outputs the invoice as described At least part of the block head of event block.In another embodiment, the calculated event for outputing the invoice The digest value of block and with the last one before the event block for outputing the invoice is not recorded on the block chain The digest value of block, at least part of the block head as the event block for outputing the invoice.In another implementation In example, the digest value of the calculated event block for outputing the invoice and with described open is not recorded on the block chain The digest value of the block main body of the last one block before the event block of the invoice out outputs the invoice as described Event block block head at least part.

Since the event of all invoices on block chain chronologically records, and multiple invoices may be recorded on a block chain Event, therefore, the last one block before not recording the event block for outputing the invoice on block chain is different It surely is current invoice, it may be possible to other invoices.For example, block chain has been recorded with 6 blocks, it is respectively according to timing:

1) distribution of invoice 1；

2) distribution of invoice 2；

3) invoice 1 is made out an invoice:

4) distribution of invoice 3；

5) reimbursement of invoice 1；

6) invoice 2 is made out an invoice.

Current invoice is invoice 3.When invoice 3 is made out an invoice, need to increase block on block chain, i.e. invoice 3 is opened The block of ticket event, as the 7th block, and the last one block before not recording the 7th block on block chain is 6 blocks are about the 2nd invoice.Just because of regardless of do not record on block chain the event block for outputing the invoice it Whether the last one preceding block is about current invoice, in one embodiment, all by its digest value (or its block main body Digest value) be recorded in the digest value (or digest value of current block) of the block main body of current block together as working as proparea At least part of the block head of block, therefore, letter of each block all containing the upper block in block chain on block chain Breath, itself information are also recorded by next block on block chain, and close verifying relationship is formed between block, therefore, The block of block chained record is difficult to be tampered, and substantially increases the safety that invoice information is stored and verified on block chain.It presses According to the block main body digest value of the event block for outputing the invoice, so that it may find opening of recording on the block chain The event block of the invoice out.

In step 430, the invoice information in the event block found, event of making out an invoice invoice transinformation respectively with When the invoice submits an expense account the invoice information and consistent event invoice transinformation of making out an invoice in request, sending allows the invoice The response of reimbursement.

If invoice information, event of making out an invoice invoice transinformation in the event block found respectively with the invoice report Invoice information and event invoice transinformation of making out an invoice in pin request is consistent, in the case of just illustrating that employee submits an expense account on line There is no to distort invoice information when making out an invoice on line, is somebody's turn to do after electronic invoice is printed in the case of reimbursement under line without manually altering The invoice of printing, otherwise will cause the information in the event block found and the information in invoice reimbursement request is different It causes.Under the two unanimous circumstances, the response for allowing invoice to submit an expense account is issued to reimbursement unit terminal 101.In this way, just verifying The case where invoice is distorted avoids the case where submitting an expense account after invoice is distorted.

As shown in figure 5, the method is after step 430 according to one embodiment of the disclosure, further includes:

Step 440 receives reimbursement invoice transfer request, and the reimbursement invoice transfer request includes invoice information, reimbursement thing Part invoice transinformation；

Step 450, the reimbursement hair that the invoice information, reimbursement event invoice transinformation are recorded on block chain In the event block of ticket.

The event block of the reimbursement invoice has to including the invoice information, reimbursement event invoice transinformation Block main body carry out the reimbursement invoice that abstract operation obtains event block block main body digest value.

Step 440-450 is described in detail below.

In step 440, reimbursement invoice transfer request is received, the reimbursement invoice transfer request includes invoice information, report Pin event invoice transinformation.

Reimbursement unit terminal 101 is after the response for whether invoice being allowed to submit an expense account, also by invoice reimbursement event as schemed Timely cochain shown in 3B.If not cochain, invoice circulation follow-up link can not just learn whole letters in the invoice intermediate links Breath, when follow-up link needs to verify since loss of learning will lead to the conclusion of mistake.Therefore, reimbursement unit terminal 101 needs Reimbursement invoice transfer request is issued to block chain gateway server 401.

In the case where submitting an expense account on line, which is in response in financial staff on the interface of Fig. 1 M "Yes" is selected to carry out.In the case where online lower reimbursement, since reimbursement unit does not have online, it, which will not also be indifferent to, will submit an expense account thing Part is to block chained record.Whether whether it be tampered to verify invoice or repeat to submit an expense account, and may utilize the embodiment of the present disclosure Method to block chain gateway server 401 inquiry whether allow to submit an expense account, but not to block chained record submit an expense account event.

The reimbursement invoice transfer request includes invoice information, reimbursement event invoice transinformation.It, should as shown in Fig. 1 N Invoice information is the Automatic generation of information in the electronic invoice sent according to employee to reimbursement unit terminal.Report in the interface Pin event invoice transinformation includes the side's of producing information, the side's of being transferred to information, the side's of producing phone etc..The side's of producing information is according to invoice For receiptor's information in information come what is generated, the side's of being transferred to information is generated according to the invoice new line title in invoice information, The side's of producing phone is generated according to receiptor's phone in invoice information.Invoice information, reimbursement event invoice transinformation Cochain for follow-up link (such as audit link, support tax link, repeat reimbursement link) verifying play a significant role.Invoice letter The cochain of breath ensure that whether the invoice that follow-up link is able to verify that follow-up link is related to is that nothing distorts invoice, and invoice transfer is believed Breath, which repeats reimbursement for verifying, has important information, and this point can be in subsequent detailed description.

In step 450, the invoice information, reimbursement event invoice transinformation are recorded on block chain described in reimbursement In the event block of invoice, the event block of the reimbursement invoice has to including the invoice information, reimbursement event hair The block main body of ticket transinformation carries out the abstract of the block main body of the event block for the reimbursement invoice that abstract operation obtains Value.

As shown in fig. 6, in one embodiment, step 450 may include:

Step 4501 carries out abstract fortune to the block main body for including the invoice information, reimbursement event invoice transinformation It calculates, generates the digest value for submitting an expense account the block main body of event block of the invoice；

Step 4502, digest value and the block chain by the block main body of the event block for submitting an expense account the invoice On do not record the reimbursement invoice event block before the last one block digest value together, as the reimbursement At least part of the block head of the event block of the invoice；

Step 4503, the thing by the invoice information, reimbursement event invoice transinformation, as the reimbursement invoice At least part of the block main body of part block；

Step 4504 connects the block head and the block main body, as the event block for submitting an expense account the invoice, with It is recorded in block chain.

These steps are described in detail below.

Abstract operation in step 4501 can be hash algorithm etc..It, which can be, believes invoice with link of making out an invoice above It ceases, the abstract operation that event of making out an invoice invoice transinformation carries out is the same operation.It in one embodiment, can also be for not Different digest algorithms are directed to invoice, same digest algorithm is arranged in distribution, the links such as make out an invoice, submit an expense account in the same invoice. Block chain gateway server 401 can safeguard an invoice mark and digest algorithm mapping table.When needed in 4501 into When row abstract operation, which is searched according to the invoice mark (invoice codes+invoice number) in invoice information, is obtained Digest algorithm carries out abstract operation.Benefit for different invoices for different digest algorithms is, so that digest value is difficult to be broken Solution further increases the safety of block record information.

In step 4502, similar to the situation of above-mentioned event block record of making out an invoice, by the event of the reimbursement invoice The digest value of the block main body of block, with the reimbursement invoice is not recorded on the block chain event block before most Together, the meaning being recorded in the block head of the event block of the reimbursement invoice is the digest value of the latter block, Information of each block all containing the upper block in block chain on block chain, the block information of itself is also by block chain On next block recorded, close verifying relationship is formed between block, therefore, the block of block chained record is difficult to be usurped Change, substantially increases the safety that invoice information is stored and verified on block chain.

The digest value and the block of the block main body of event block of the block head in addition to recording the reimbursement invoice Except the digest value for not recording the last one block before the event block of the reimbursement invoice on chain, when also store Between stamp, check code etc..Timestamp record generate the block time, be automatically logged into when generating the block block head when Between stab field.Check code is utilized to the position (except the position of the check code) for the other parts for including block head and the position of block main body The position that parity arithmetic generates, the position is for verifying whether the block is changed, and if the block is changed, utilizes Parity arithmetic carries out operation to the position (except the position of the check code) of other parts and the position of block main body, and obtained result is just It can be different from the check code.In this way, the block has been further prevented to be tampered.

The feelings of the generation type and above-mentioned event block record of making out an invoice of block main body and block head in step 4503 and 4504 Shape is also similar, therefore does not repeat.

Above-described embodiment only avoids the case where virtual invoice reimbursement, in a further embodiment, additionally it is possible to Invoice is avoided to repeat to submit an expense account.It is by not only judging when block chain gateway server 401 determines whether invoice reimbursement The invoice information in event block, event of the making out an invoice invoice transinformation that find submit an expense account the hair in request with the invoice respectively Whether ticket information and event invoice transinformation of making out an invoice are consistent, also judge the invoice ownership side information registered at present and reality What whether claimer's information unanimously carried out.

In the embodiment, the invoice reimbursement request can also contain claimer's information.In this way, Fig. 1 I and Fig. 2 C's On interface, the frame (not shown) for filling in " claimer's information " may be had more.The financial staff for submitting an expense account unit needs will be real The employee information of border request reimbursement fills in the frame of " claimer's information ".In this way, sent to block chain gateway server 401 Invoice reimbursement request just contains claimer's information.

In this way, as shown in fig. 7, step 430 may include:

Step 4301, the invoice information in the event block found, event of making out an invoice invoice transinformation respectively with institute When stating the invoice information and consistent event invoice transinformation of making out an invoice in invoice reimbursement request, the ownership of the invoice is inquired Square information；

Step 4302, when the ownership side's information inquired is consistent with claimer's information, sending allows the invoice The response of reimbursement.

Ownership side's information of the inquiry invoice in step 4301 can be there are many implementation.

In one embodiment, the ownership side's information for inquiring the invoice can be by inquiring the hair recorded in block chain The invoice side of the being transferred to information realization of a block the latest in the event block of ticket.As described above, invoice distribution, make out an invoice, report The links such as pin, require by event cochain, and not only by invoice information cochain when cochain, but also will be in invoice transinformation Chain.It is identified in invoice information containing invoice.As described above, containing the invoice side of producing information and can be transferred in invoice transinformation Square information etc..Those of the mark of the invoice in requesting block is submitted an expense account with the invoice in invoice information on entire block chain, just It is all event blocks that the invoice is currently recorded on block chain.The thing of record time the latest is found in these event blocks Part block, the invoice side of the being transferred to information in invoice transinformation therein are exactly ownership side's information of current invoice.

Therefore, such as Fig. 8, in this embodiment, step 4301 includes:

Step 43011 determines and remembers in the event block identified on block chain with the invoice in invoice reimbursement request Record the event block of time the latest；

Step 43012, ownership side's letter by the invoice side of the being transferred to information in definite event block, as the invoice Breath.

The embodiment utilizes the invoice side of being transferred to of a block the latest in the event block of the invoice recorded in block chain Information realizes ownership side's information without record outside additional chain to search ownership side's information of invoice Determination, be conducive to optimize the level of resources utilization.

In addition, in other embodiments, also can use and record the mode of invoice ownership side outside block chain to realize invoice The lookup of ownership side's information.

In one embodiment, it can be recorded using the invoice ownership table outside chain.In invoice ownership table, each hair The invoice mark of ticket is correspondingly recorded with ownership side's information.This requires invoice is issued, is made out an invoice, submitting an expense account the same of event cochain When, also to update the invoice ownership table.At this moment, when requiring to look up current invoice ownership side, due to invoice ownership table Record identifies the invoice ownership side of corresponding update with each invoice, therefore, table can be belonged to from the invoice and is directly read and hair Ticket identifies ownership side's information to one.

In this embodiment, the method is after step 440, further includes: with the reimbursement event invoice transinformation In the invoice ownership table corresponding with invoice mark that is arranged except the block chain of the invoice side of being transferred to information replacement in Ownership side's information.

The invoice side of the being transferred to information generation when invoice reimbursement event occurs, in the reimbursement event invoice transinformation The table newest side to circulate of invoice submits an expense account the terminal of unit, therefore, with the side of being transferred to, information is replaced in invoice ownership table Ownership side's information corresponding with corresponding invoice mark, so that it may achieve the purpose that ownership side's information update.

Correspondingly, ownership side's information of the inquiry invoice includes: to identify according to the invoice, inquires the invoice Belong to table, to obtain ownership side's information.In this way, if employee with same invoice repeat submit an expense account when, if preceding primary reimbursement Be to be carried out on line, that is, complete the transfer of invoice ownership, in other words, will in previous reimbursement will with the invoice identify pair The ownership side's information in invoice ownership table answered has been changed to reimbursement unit rather than employee itself, and in this reimbursement, report Selling people is still the employee, will result in claimer in this way and invoice ownership side is inconsistent, thus is not submitted an expense account.In this way Primary reimbursement is the repetition reimbursement in the case where carrying out on line before avoiding.It is the case where reimbursement under line as preceding primary reimbursement, How to avoid repeating to submit an expense account, describe below.

How the foregoing describe link is submitted an expense account in invoice, invoice is updated while event cochain and belong to table.It is sent out in invoice Row and the link made out an invoice, it is also the same to require to update invoice ownership table while event cochain.

The process that invoice ownership table is updated while the link event cochain made out an invoice is as shown in Figure 9.Step 410 it Before, which comprises

Step 404 receives invoicing request, and the invoicing request includes the distribution hair recorded on block chain Mark, invoice information, the distribution event invoice transinformation of the event block of ticket；

Step 405, according to the distribution invoice event block mark, search the hair recorded on the block chain The event block of the row invoice；

Step 406, the invoice information in the event block found, distribution event invoice transinformation respectively with it is described When invoice information and consistent distribution event invoice transinformation in invoicing request, the response that allows to make out an invoice is sent；

Step 407 receives invoicing transfer request, and the invoicing transfer request includes invoice information, thing of making out an invoice Part invoice transinformation, the event invoice transinformation of making out an invoice includes the invoice side of being transferred to information；

Step 408, using the invoice information, event of making out an invoice invoice transinformation as the event block for outputing the invoice At least part of block main body be recorded on block chain, the event block for outputing the invoice, which has, outputs the hair The block main body digest value of the event block of ticket, it is described to output the hair as the mark for the event block for outputing the invoice The block main body digest value of the event block of ticket passes through to the block for including the invoice information, event of making out an invoice invoice transinformation Main body carries out abstract operation and obtains；

Step 409 is replaced and invoice mark pair with the invoice side of the being transferred to information in the event invoice transinformation of making out an invoice The ownership side's information in invoice ownership table answered.

These steps are described in detail below.

Invoicing request is received in step 404 is in response to employee in unit of making out an invoice in terminal 201 of making out an invoice such as figure " confirmation " button is selected on interface shown in 1B and is realized.Since when issuing invoice, industrial and commercial organ disposably provides invoice Multiple continuous invoices of number are to unit of making out an invoice.Make out an invoice in terminal 201 be usually according to this multiple invoice sequence by it is small to It successively outputs greatly, i.e., by the invoice number for the smallest invoice of invoice number that do not outputed also at present in this multiple continuous invoice Code is shown on the interface of Figure 1B.Content on the left of Figure 1B is invoice issuing system according to letter intrinsic in invoice issuing system What breath automatically generated, the content on right side is that the employee to draw a bill fills according to actual needs when drawing a bill.When selection is " true Recognize " after button, the content of Figure 1B will act as invoice information and be sent to block chain gateway server 401.

In one embodiment, the mark for issuing the event block of the invoice is exactly to the event zone for issuing the invoice The block main body of block carries out digest value obtained from abstract operation.

In another embodiment, the mark for issuing the event block of the invoice is exactly to the event for issuing the invoice Block (including block main body and block head) carries out digest value obtained from abstract operation.

In another embodiment, the mark for issuing the event block of the invoice is to issue the event block of the invoice Height on block chain.

Distribution event invoice transinformation includes the invoice side of producing information, the invoice side of being transferred to information etc., and wherein invoice produces Square information is generated according to the title of industrial and commercial organ, consistent with the title of industrial and commercial organ；The invoice side of being transferred to information is according to neck People (drawer) is taken to generate, it is consistent with receiptor (drawer).Issue the block main body abstract of the event block of the invoice Value is as described above, be to carry out abstract operation to the block main body for including invoice information, distribution event invoice transinformation and generate 's.

In step 405, since block main body digest value energy unique identification goes out to issue the event block of the invoice, because This, according to the block main body digest value, so that it may find the event block of the distribution invoice recorded on the block chain.

In a step 406, the invoice information in the event block found, distribution event invoice transinformation respectively with When invoice information and consistent distribution event invoice transinformation in invoicing request, answering of allowing to make out an invoice is sent It answers.

If the invoice information, distribution event invoice transinformation in the event block found output hair with described respectively Invoice information and distribution event invoice transinformation in ticket request is consistent, and the unit that illustrates to make out an invoice does not forge adulterium invoice Behavior, the invoice be it is legal, allow to output.

In step 407, invoicing transfer request is received, the invoicing transfer request includes invoice information, opens Ticket event invoice transinformation, the event invoice transinformation of making out an invoice includes the invoice side of being transferred to information.

Invoice transfer request is the request of chained record in the event by invoicing.What is issued in step 404 outputs hair Ticket request, which is only whether request is problematic to invoice, to be verified, and there is no problem then allows to output.But it is not in block chain On record this invoice transfer process.If not recording this process, it is subsequent reimbursement, audit etc. links if can lack comparison, The basis of verification is unfavorable for the progress of follow-up link.Therefore, terminal of making out an invoice 201 can be issued to block chain gateway server 401 and be sent out Invoice information and event invoice transinformation of making out an invoice are recorded on block chain on a block by ticket transfer request.Invoice information It can be generated according to the information on interface shown in Figure 1B.Event of making out an invoice invoice transinformation includes the invoice side of producing information, turns The side's of entering information, the side's of being transferred to phone etc..The invoice side of producing information is the invoice issuing system as terminal 201 of making out an invoice according to Figure 1B Drawer automatically generate.The invoice side of being transferred to information is the invoice issuing system as terminal 201 of making out an invoice according to shown in Figure 1B What receiptor automatically generated.The side's of being transferred to phone is as the invoice issuing system receiptor according to shown in Figure 1B for terminal 201 of making out an invoice What phone automatically generated.

In a step 408, using the invoice information, event of making out an invoice invoice transinformation as the event for outputing the invoice At least part of the block main body of block, is recorded on block chain, and the event block for outputing the invoice, which has, to be outputed The digest value of the block main body of the event block of the invoice, it is described to open as the mark for the event block for outputing the invoice The block main body digest value of the event block of the invoice passes through to including the invoice information, event of making out an invoice invoice transfer letter out The block main body of breath carries out abstract operation and obtains.

It in one embodiment, can will include the invoice information, the block main body of event of making out an invoice invoice transinformation Abstract operation is carried out, block main body digest value is obtained.Then, a newly-generated block on block chain.The block that this is obtained At least part of the digest value of previous block as the block head of new block on main body digest value and block chain.By the hair At least part of ticket information, event of making out an invoice invoice transinformation as the block main body of new block.

In step 409, it is replaced and invoice mark with the invoice side of the being transferred to information in the event invoice transinformation of making out an invoice Know ownership side's information in corresponding invoice ownership table.

Record invoice mark and the newest ownership side's information of invoice in invoice ownership table.Before making out an invoice, which returns Ownership side's information of the corresponding invoice mark recorded in category table is unit of making out an invoice, but after making out an invoice, and the ownership side of invoice occurs Variation, becomes invoice receiptor, that is, the invoice side of the being transferred to information in event of making out an invoice invoice transinformation.Therefore, bill after date, Other than the event of making out an invoice needs cochain, it is also necessary to the invoice side of the being transferred to information replacement in event of making out an invoice described in invoice transinformation Ownership side's information in corresponding invoice ownership table is identified with invoice, invoice ownership side is completed and updates.In this way, being subsequent verifying It needs to provide convenience when the ownership side of checking of invoice in link.

The process that invoice ownership table is updated while issuing the link event cochain of invoice is as shown in Figure 9.In step 404 Before, which comprises

Step 401 receives distribution invoice request, and the distribution invoice request turns comprising invoice information, distribution event invoice Move information；

Step 402, using the invoice information, distribution event invoice transinformation as the event block of the distribution invoice Block main body at least part, be recorded in block chain, wherein issue the invoice event block have distribution described in The digest value of the block main body of the event block of invoice, as the mark for the event block for issuing the invoice, the sale room The block main body digest value of the event block of invoice is stated by including the invoice information, distribution event invoice transinformation Block main body carries out abstract operation and obtains；

The invoice side of being transferred to information in the distribution event invoice transinformation is written and invoice mark pair step 403 Ownership side's information is used as in the invoice ownership table answered.

Step 401-403 is described in detail below.

Distribution invoice is received in step 401 to request to be in response to staff's hair shown in Figure 1A in industrial and commercial organ The interface of ticket issuing system selects " confirmation " button and carries out.The boundary of the invoice information such as Figure 1A contained in distribution invoice request Information shown in face.Distribution event invoice transinformation includes the invoice side of producing information, the invoice side of being transferred to information etc..Invoice produces Square information is that the make out an invoice invoice publishing system of terminal 301 is generated automatically according to the issuing house information in Figure 1A.Invoice is transferred to Square information is that the make out an invoice invoice publishing system of terminal 301 is generated automatically according to the application invoice unit information in Figure 1A.

It in step 402, in one embodiment, can will include the invoice information, distribution event invoice transfer letter The block main body of breath carries out abstract operation, obtains block main body digest value.Then, a block, the area are generated on block chain Block is first block that the invoice records on block chain.In one embodiment, the block main body digest value this obtained In the block head for being placed on the block together with the digest value of the block main body of block previous on block chain.In another embodiment In, it can also be by previous block on block main body digest value that this is obtained and block chain (including block main body and block head) Digest value is placed on together in the block head of the block.The invoice information, distribution event invoice transinformation are placed on the block Block main body in.

Record invoice mark and the newest ownership side's information of invoice in invoice ownership table.Before invoice distribution, the hair The corresponding relationship record that the invoice identifies corresponding any invoice mark and ownership side's information is not recorded in ticket ownership table.It is sending out The invoice distribution event block that ticket records when issuing is first record in invoice ownership table of invoice mark.In invoice Before distribution, invoice owner is industrial and commercial organ.After invoice distribution, becomes and claim invoice unit, that is, unit of making out an invoice. Therefore, after invoice distribution, other than the authenticity of the link checking of invoice after invoice distribution event needs cochain to be convenient for, also Need by the invoice issue event invoice transinformation in the invoice side of being transferred to information write-in invoice ownership table in, as with hair Ticket identifies corresponding ownership side's information.In this way, the side of providing when to need the ownership side of checking of invoice in subsequent verifying link Just.

In one embodiment, it in addition to using invoice to belong to off-balancesheet other than chain, can also be stepped on using the invoice transfer outside chain Remember table.In invoice transfer registration table, ownership side's information of current invoice can be equally got.

In this embodiment, after step 440, the method also includes: by the reimbursement event invoice transinformation It is recorded in the invoice transfer registration table corresponding with invoice mark being arranged except the block chain.Invoice transfer registration table record Identified with invoice corresponding generation each event invoice transinformation.Each invoice mark corresponds to an invoice transfer Registration form.For example, corresponding with an invoice mark issue, make out an invoice, submitting an expense account event invoice transinformation, it is recorded in this invoice It identifies in corresponding invoice transfer registration table.Invoice transinformation includes the invoice side of producing information, the side's of being transferred to information etc..Work as hair After ticket distribution, invoice transfer registration table records the invoice and identifies corresponding distribution event invoice transinformation.Work as bill after date, sends out Ticket transfer registration table not only records the invoice and identifies corresponding distribution event invoice transinformation, also records invoice mark Corresponding event invoice transinformation of making out an invoice.After reimbursement, it is corresponding that invoice transfer registration table not only records invoice mark Distribution event invoice transinformation, event of making out an invoice invoice transinformation also record the invoice and identify corresponding reimbursement event hair Ticket transinformation.Its benefit is not only to record the static information of a current point in time, also record invoice and entirely shifted The history of journey.

In this embodiment, the method is after step 440, further includes: by the reimbursement event invoice transinformation It is recorded in the invoice transfer registration table corresponding with invoice mark being arranged except the block chain.It, can be by institute in record It states reimbursement event invoice transinformation and invoice identifies corresponding record.

Correspondingly, ownership side's information of the inquiry invoice includes: to identify according to the invoice, inquires the invoice Transfer registration table, each invoice transinformation in the invoice transfer registration table has the invoice side of being transferred to information, by the hair The invoice side of being transferred to information in the last one invoice transinformation of ticket transfer registration table, as ownership side's information.Invoice turns It moves the last one invoice transinformation of registration form and represents the last one event occurred at present about the invoice, sent out in the event The ticket side of being transferred to information is exactly ownership issue side's information of current invoice.

The foregoing describe link is submitted an expense account in invoice, how invoice transfer registration table is updated while event cochain.It is sending out The link that ticket is issued and makes out an invoice, it is also the same to require to update invoice transfer registration table while event cochain.

The process that invoice transfer registration table is updated while the link event cochain made out an invoice is as shown in Figure 10.In step Before 410, which comprises

Step 404 ', receive invoicing request, invoicing request is comprising described in the distribution that records on block chain Mark, invoice information, the distribution event invoice transinformation of the event block of invoice；

Step 405 ', according to the distribution invoice event block mark, search and recorded on the block chain Issue the event block of the invoice；

Step 406 ', the invoice information in the event block found, distribution event invoice transinformation respectively with institute When stating the invoice information and consistent distribution event invoice transinformation in invoice reimbursement request, the response for allowing to make out an invoice is sent；

Step 407 ', receive invoicing transfer request, the invoicing transfer request includes invoice information, thing of making out an invoice Part invoice transinformation, the event invoice transinformation of making out an invoice includes the invoice side of being transferred to information；

Step 408 ', using the invoice information, event of making out an invoice invoice transinformation as the event zone for outputing the invoice At least part of the block main body of block, is recorded on block chain, and the event block for outputing the invoice, which has, outputs institute The block main body digest value of the event block of invoice is stated, it is described to output institute as the mark for the event block for outputing the invoice The block main body digest value of the event block of invoice is stated by including the invoice information, event of making out an invoice invoice transinformation Block main body carries out abstract operation and obtains；

Step 409 ', the event invoice transinformation of making out an invoice is recorded in invoice transfer registration corresponding with invoice mark In table.

Step 404 ' -408 ' are almost the same with step 404-408 respectively, therefore do not repeat.In step 409 ' in, it will be described Event of making out an invoice invoice transinformation is recorded in invoice transfer registration table corresponding with invoice mark.It occurs in the event of making out an invoice Before, invoice information, the distribution event invoice that corresponding distribution event is identified with the invoice are record in the invoice transfer registration table Transinformation.After event of making out an invoice occurs, it will increase in the invoice transfer registration table and record open corresponding with invoice mark The invoice information of ticket event, event of making out an invoice invoice transinformation.In this way, needing the ownership of checking of invoice for subsequent verifying link Information in the overall process of side or even checking of invoice transfer both provides conveniently.

The process of invoice transfer registration table is updated while issuing the link event cochain of invoice as shown in Figure 10.In Step 404 ' before, which comprises

Step 401 ', receive distribution invoice request, distribution invoice request includes invoice information, event of making out an invoice invoice turn Move information；

Step 402 ', using the invoice information, event of making out an invoice invoice transinformation as the event zone for issuing the invoice At least part of the block main body of block, is recorded on block chain, wherein the event block for issuing the invoice has sale room The block main body digest value for stating the event block of invoice, as the mark for the event block for issuing the invoice, the sale room The block main body digest value of the event block of invoice is stated by including the invoice information, distribution event invoice transinformation Block main body carries out abstract operation and obtains；

Step 403 ', the distribution event invoice transinformation is recorded in invoice transfer registration corresponding with invoice mark In table.

Below to step 401, ' -403 ' are described in detail.

Step 401 ' -402 ' are similar with step 401-402, therefore do not repeat.In step 403 ' in, the distribution event is sent out Ticket transinformation is recorded in invoice transfer registration table corresponding with invoice mark.Before invoice distribution, without invoice, also have There is no corresponding invoice to identify, therefore does not create invoice transfer registration table corresponding with invoice mark.After invoice distribution, Each invoice of creation and distribution identifies corresponding invoice transfer registration table, will remember the distribution event invoice transinformation Record is in invoice transfer registration table corresponding with invoice mark.As shown in Figure 1A, may issue together invoice codes is 2873ERST2,100 invoices that invoice number is 100001-100100, establish corresponding invoice for this 100 invoices respectively Transfer registration table, and will include that the invoice transfer registration is written in the invoice side of producing and the distribution event invoice transinformation for the side of being transferred to Table.

In one embodiment, the reimbursement event invoice transinformation has the invoice side of producing information and the invoice side of being transferred to Information.Such as Figure 11, after step 450, the method also includes:

Step 460 receives and submits an expense account request of making loans, and has in the request of making loans and asks money people's information；

If containing report in the event block of record time the latest with invoice mark in step 470, block chain Pin event invoice transinformation, the invoice side of producing information in the reimbursement event invoice transinformation and asks money people information one It causing, the invoice side of the being transferred to information in the reimbursement event invoice transinformation is consistent with the caller information of request of making loans is submitted an expense account, Then issue the response for allowing to make loans.

In the embodiment, submits an expense account the processing made loans and occur to shift in the invoice ownership of reimbursement event cochain, registration Afterwards, this is it is advantageously ensured that invoice has been completed the transfer of ownership as a kind of assets when making loans, i.e., after assets transfer, Wealth transfer is just carried out, the safety made loans is improved.

After the invoice ownership of reimbursement event cochain, registration shifts, employee can operate in employee's terminal 102 Request is made loans, such as certain operation can be carried out on the display interface of the electronic invoice in card packet (such as on touch interface One " request is made loans " button), it requests to make loans to reimbursement unit terminal 101.After being connected to the request of the employee, reimbursement unit is whole End 101 sends one to block chain gateway server 401 and submits an expense account request of making loans, the employee to make loans automatically according to request in the request Money people's information is asked in (owner of employee's terminal), addition one.It is asked when block chain gateway server 401 receives the reimbursement and makes loans After asking, the last one block with invoice mark recorded on verification block chain first is a reimbursement event block (this point from whether can judge containing reimbursement event invoice transinformation).If not reimbursement event block, then say The bright transfer without completing invoice ownership in reimbursement, not can be carried out and makes loans.If it is reimbursement event block, also to check described The invoice side of producing information in reimbursement event invoice transinformation whether with ask money people information (employee) unanimously, the reimbursement event The invoice side of being transferred to information in invoice transinformation whether with reimbursement make loans request sender's (reimbursement unit) it is consistent.If all Unanimously, it can just make loans.If inconsistent, refusal is made loans.

The above process embodies to become apparent in the interaction diagrams of Figure 13 A.When employee needs to submit an expense account on line, by electronics Invoice is transmitted to reimbursement unit terminal 101 by electronic invoice system.Unit terminal 101 is submitted an expense account to block chain gateway server 401 send invoice reimbursement request, for allowing block chain gateway server 401 to examine true from false of bills, while determining whether invoice belongs to It is submitted an expense account in repetition.If invoice is true, and is not belonging to repeat to submit an expense account, then block chain gateway server 401 is to reimbursement unit terminal 101 send the response for allowing to submit an expense account.It submits an expense account unit terminal 101 and sends the response that reimbursement is completed to employee's terminal 102.Submit an expense account unit Terminal 101 also sends reimbursement invoice transfer request to block chain gateway server 401.Block chain gateway server 401 receives After the request, invoice is submitted an expense account into event cochain, and updates relevant invoice attaching information (such as invoice outside chain belongs to table, invoice Transfer registration table etc.).When employee's terminal 102 requests to make loans, reimbursement unit terminal 101 is looked into block chain gateway server 401 It askes whether invoice has been carried out ownership transfer, i.e., cochain and carries out attaching information update.If so, then block chain gateway server 401 send the response that transfer is completed to reimbursement unit terminal 101.Then, reimbursement unit terminal 101 is put to employee's terminal 102 Money, such as transferred accounts by wechat.

As described above, if employee with same invoice repeat submit an expense account when, if it is preceding it is primary reimbursement be to be carried out on line, due to Must carry out reimbursement event cochain in reimbursement on line, and invoice ownership transfer is to reimbursement unit, in this way, this claimer and It invoice ownership side will be inconsistent.Primary reimbursement is the repetition report in the case where carrying out on line before avoiding in this way Pin.But it if preceding primary reimbursement is submitted an expense account under line, is submitted an expense account under line not and will do it reimbursement event cochain and the registration of invoice ownership It is transferred to reimbursement unit, can not just find and whether repeat the case where submitting an expense account.In order to which the reimbursement in the case where preceding primary reimbursement is line (will be electric Unit reimbursement after sub- printing invoice some without online condition) in the case where, repetition reimbursement can be also found, in a reality It applies in example, primary reimbursement is the repetition reimbursement in the case where submitting an expense account under line before preventing in this way: once electronic invoice It is printed, electronic invoice is just recorded as lock state, and invoice only allows reimbursement one after being registered as lock state Secondary, i.e., to being connected to for the first time after locking the reception invoice reimbursement request with invoice mark, sending allows the invoice report The response of pin.In this way, do not allow then to submit an expense account if it is invoice reimbursement request is received after electronic invoice printing for the second time, thus Primary reimbursement is the repetition reimbursement in the case where submitting an expense account under line before preventing.

As shown in figure 12, in one embodiment, before step 410, the method also includes:

Step 4001 receives print request under invoice line, and print request is identified with invoice under the invoice line；

The invoice is identified corresponding invoice and is recorded as lock state by step 4002, and the lock state only allows pair The invoice is being identified to the reception hair with invoice mark being connected to for the first time after corresponding invoice is recorded as lock state Ticket reimbursement request, sends the response for allowing the invoice to submit an expense account；

Step 4003 prints the invoice, and the opening with invoice mark recorded on block chain is printed on the invoice The corresponding graphic code of mark of the event block of the invoice out.

In step 4001, employee is as shown in Figure 2 A in employee's terminal 102, after selecting " having connected, start to print ", to area Block chain gateway server 401 issues print request under invoice line.It is identified due to being stored in the wechat card packet of Fig. 1 H comprising invoice Invoice information, the wechat card packet can automatically by the invoice mark be added to print request under invoice line.Block chain gateway service Device 401 receives under the invoice line after print request, is identified according to invoice therein, and corresponding invoice is recorded as locking shape State.The method of record locking state is described below.Then, start printed invoice, be printed on the invoice printed for example two-dimentional The graphic code of code, the graphic code correspond to event zone recording on block chain, with invoice mark, outputing the invoice The mark of block, the event block of the mark unique identification invoicing.

In this way, when being submitted an expense account at the financial staff that the invoice printed is taken reimbursement unit by employee, financial staff With the scanner scanning graphic code, the mark of the event block for outputing the invoice will be obtained.In this case, it walks Rapid 4302 include: when the ownership side's information inquired is consistent with claimer's information, if it is determined that the invoice mark pair Though the invoice answered be not in lock state or be in the lock state receive invoice reimbursement request be to identify the invoice Corresponding invoice is recorded as the reception invoice reimbursement request with invoice mark being connected to for the first time after lock state, then sends Allow the response of the invoice reimbursement.

That is, the ownership side's information inquired is consistent with claimer's information can only prevent before primary reimbursement be line Repetition reimbursement when upper reimbursement.It, can be by determining whether that the invoice mark corresponds to if preceding primary reimbursement is submitted an expense account under line Though invoice be not in lock state or be in the lock state receive invoice reimbursement request be by the invoice mark pair The reception invoice reimbursement request with invoice mark that the invoice answered is recorded as being connected to for the first time after lock state is to prevent.Such as Invoice described in fruit identifies corresponding invoice and is not in lock state, illustrates to submit an expense account under no printed invoice line, therefore be safe. If be in the lock state, it at this moment will judge that the reception invoice reimbursement request with invoice mark is which time is received. It is still safe if it is first time.It is then to repeat to submit an expense account if it is number later.In this way, it is therefore prevented that preceding Primary reimbursement is the repetition reimbursement submitted an expense account under line.

In one embodiment, determine the invoice identify corresponding invoice be not in lock state in the following way into Row:

Locking information table corresponding with invoice mark is set, is recorded as locking wherein the invoice is identified corresponding invoice When state, lock state record is that invoice identifies in corresponding locking information table；

According to the invoice mark in the invoice reimbursement request received, locking information corresponding with invoice mark is searched Table；

If non-record locking state in locking information table, it is determined that the invoice identifies corresponding invoice and is not in locking State.

In one embodiment, one corresponding locking information table of setting is identified for each invoice.If the invoice does not have It is registered as lock state, which does not store any information.Alternatively, the locking information table is only recorded for invoice It is just generated after lock state.After having recorded lock state for invoice, lock state record is invoice mark pair In the locking information table answered.For example, the specific fields of locking information table are set 1.At this moment, when it needs to be determined that invoice mark pair When whether the invoice answered is in the lock state, it is only necessary to according to receive invoice reimbursement request in invoice identify, search with The invoice identifies corresponding locking information table, and judges whether respective field sets 1 in locking information table.If setting 1 to illustrate to lock It is fixed, if it is unlocked not set 1 explanation.

In addition, in this embodiment, received though determining that the invoice identifies corresponding invoice and is in the lock state Invoice reimbursement request be the invoice identifies to corresponding invoice is recorded as being connected to for the first time after lock state there is the invoice The reception invoice reimbursement request of mark can also carry out in the following way:

Locking information table corresponding with invoice mark is set, is recorded as locking wherein the invoice is identified corresponding invoice When state, lock state record is that invoice identifies in corresponding locking information table, and be somebody's turn to do in response to receiving to have The invoice of invoice mark submits an expense account request, and invoice reimbursement request is recorded in the locking information table；

If record locking state in locking information table, and invoice reimbursement request has not been recorded in the locking information table, Though then determining that the invoice identifies corresponding invoice and is in the lock state, the invoice reimbursement request received is by the invoice It identifies corresponding invoice and is recorded as the reception invoice reimbursement request with invoice mark being connected to for the first time after lock state.

That is, locking information table not only records whether invoice is in the lock state, also it is recorded in and is in the lock state The invoice reimbursement request received later.In this way, if record locking state in locking information table, but in the locking information table Invoice reimbursement request has not been recorded, illustrates that the invoice of invoice mark was not submitted an expense account after locking.It such as submitted an expense account, the locking information Invoice reimbursement request is had in table.In this way, determining that out such case not is to repeat to submit an expense account, reimbursement can permit.

The above process embodies to become apparent in the interaction diagrams of Figure 13 B.When employee needs to submit an expense account under line, by electronics Before printing invoice, print request under invoice line is sent to block chain gateway server 401.Block chain gateway server 401 receives To after the request, invoice is recorded as lock state.102 printed invoice of employee's terminal.The invoice printed is taken report by employee It sells and is submitted an expense account at the financial staff of unit.It submits an expense account unit terminal 101 and sends invoice reimbursement request to block chain gateway server 401. Block chain gateway server 401 will examine true from false of bills, determine whether the invoice is to repeat reimbursement (including to judge that invoice is currently It is no to belong to the employee, though judge whether the invoice is in the lock state or is in the lock state request reimbursement for the first time).Such as Fruit invoice is true, and is not belonging to repeat to submit an expense account, and sends the response for allowing to submit an expense account to reimbursement unit terminal 101.Submit an expense account unit terminal 101 send the response that reimbursement is completed to employee's terminal 102.Due to being submitted an expense account under line, reimbursement unit terminal 101 is not necessarily to and generally Reimbursement invoice transfer request will not be sent to block chain gateway server 401.

Invoice issue terminal 301, terminal of making out an invoice 201, invoice reimbursement terminal 101 are to invoice distribution event, event of making out an invoice, hair Invoice information and invoice transinformation in ticket reimbursement event carry out cochain.But in some cases, due to invoice issue terminal 301, terminal of making out an invoice 201, invoice reimbursement terminal 101 lack the reasons such as record, may in the future its to being recorded at that time on block chain The data of their cochains are queried, it is believed that inconsistent with the data of its cochain.In order to improve them to uplink data authenticity Trust, in one embodiment, by the way of transmitting signature simultaneously when cochain.

In one embodiment, it in each endpoint to register, (including invoice issue terminal 301, makes out an invoice end for each terminal End 201, invoice submit an expense account terminal 101, employee's terminal 102) the unique signature algorithm of distribution stores respectively in respective terminal.Each The signature algorithm of terminal can be different.In this embodiment, the reimbursement invoice transfer request is in addition to invoice information, reimbursement It further include the reimbursement terminal signing messages to invoice information, reimbursement event invoice transinformation except event invoice transinformation. Reimbursement terminal signing messages is that invoice submits an expense account terminal 101 with the signature algorithm oneself distributed to invoice information, reimbursement event invoice Obtained from transinformation is signed electronically.

In this embodiment, step 450 includes: by the invoice information, reimbursement event invoice transinformation, the reimbursement Terminal signing messages, at least part of the block main body as the event block for submitting an expense account the invoice, is recorded on block chain, Wherein, the event block of the reimbursement invoice has to including the invoice information, reimbursement event invoice transinformation, institute The block main body for stating reimbursement terminal signing messages carries out the block master for the event block for submitting an expense account the invoice that abstract operation obtains Body digest value, the mark as the event block for submitting an expense account the invoice.That is, in this case, being recorded on block chain Reimbursement event block block main body include the invoice information, reimbursement event invoice transinformation, the reimbursement terminal label Name information, rather than only include the above two.The block main body for the current block main body for including in the block head of the event block is plucked It is worth, abstract operation only is not carried out to invoice information, reimbursement event invoice transinformation and obtained, be to including invoice Information, reimbursement event invoice transinformation, the entire block main body of the reimbursement terminal signing messages three carry out abstract operation It obtains.
