Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions in the embodiments of the present application will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application. In the present application, the embodiments and features of the embodiments may be arbitrarily combined with each other without conflict. Also, while a logical order is shown in the flow diagrams, in some cases, the steps shown or described may be performed in an order different than here.

For the convenience of understanding the technical solutions provided by the embodiments of the present application, some key terms used in the embodiments of the present application are explained first:

a bill: the voucher is made according to a certain specified form and displays the voucher with the obligation of paying money, namely, the voucher can be used as a transaction voucher when a transaction occurs. Generally, the bill may include tax invoice, financial bill (such as medical bill) or business bill, etc., the invoice is generally the business certificate issued and collected by the unit and the individual in purchasing and selling goods, providing or receiving services and doing other business activities, and is the original basis for accounting; the medical ticket is a consumption certificate issued by a medical institution after the medical institution consumes the medical ticket; the business ticket is an unsecured short-term ticket issued by a financial company or an enterprise and used for financing by a ticket issuer; of course, the ticket in the embodiment of the present application may also refer to other types of tickets that can be found and reimbursed for an enterprise, for example, a ticket issued inside an enterprise, and the like.

The ticket holding user: refers to the user who owns the ticket, i.e., the user who initiated the ticket reimbursement process.

A reimbursement mechanism: the ticket issuing system refers to enterprises or government institutions and the like for which ticket holding users request to reimburse tickets to be reimbursed. For example, for invoices, the reimbursement agency is generally the company noted in the top-up of the invoice, or for medical tickets, the reimbursement agency is generally an insurance company or a government agency, etc.

An invoicing mechanism: refers to an organization such as a merchant, an enterprise, or a medical institution that issues invoices to users.

Block Chain (Block Chain): or called distributed data record book, is a chain data structure formed by combining data blocks (blocks) in a certain sequence in a sequential connection mode, and is a distributed book which is guaranteed to be not falsified and forged in a cryptology mode. The block is used for recording information related to one or more events in the invoice flow, for example, an event may refer to processes of storing a bill, transferring the bill, splitting the bill, storing a reimbursement result of the bill, and the like.

Block chain node: refers to a computing device participating in transaction processing in a blockchain network, such as a computer, a mobile phone, a desktop, a server or a server cluster, or a single computer or a part of a server, for example, a virtual machine, may be used as a node in the blockchain network. For example, each block link node may be in the form of a virtual machine cluster, that is, a part of each block link node is divided from multiple physical machines to serve as a virtual machine, and collectively function as a block link node.

The Unspent Transaction Output (UTXO) model: in the UTXO model, a transaction represents a change of the UTXO set, each transaction costs (spread) an input and produces an output (output), and the output produced is the "unspent transaction output", i.e., the UTXO. For the UTXO model, the maximum characteristic is that the UTXO model does not exist after the transaction, that is, after the transaction occurs, the content before the transaction does not exist, and for the ticket transfer process, the UTXO model may be regarded as one transaction, and the ticket to be reimbursed is an input of the transaction, and after the transaction, the ticket to be reimbursed is transferred to the reimbursement institution, and the ticket to be reimbursed of the ticket holder does not exist.

In addition, the term "and/or" herein is only one kind of association relationship describing an associated object, and means that there may be three kinds of relationships, for example, a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" in this document generally indicates that the preceding and following related objects are in an "or" relationship unless otherwise specified. Furthermore, references to "first" or "second", etc. herein are only used to distinguish between similar items and not to describe a particular order or sequence.

The bill reimbursement generally refers to a process that a user pays money in advance and then reimburses the money in a reimbursement mechanism, and the reimbursement mechanism compensates the paid money for the user. Generally, a bill is allowed to be reimbursed because an online reimbursement service generally uses reimbursement software or a reimbursement web page to perform an electronic reimbursement process, but in the current online reimbursement method, because a more effective duplication checking mechanism does not exist, repeated reimbursement may occur, and a certain risk is brought to financial processing and the like of a reimbursement institution, thereby causing property loss of the reimbursement institution.

The applicant analyzes the prior art and finds that, in the prior art, because electronic bills are generally owned or stored by ticket-holding users, and the ticket-holding users submit the electronic bills to be reimbursed by themselves during reimbursement, when reimbursement mechanisms for reimbursement requested by the ticket-holding users are different, the reimbursement mechanisms cannot know that the electronic bills are possibly reimbursed by another enterprise, and reimburse the electronic bills for the ticket-holding users according to a normal reimbursement process, so that a situation of repeated reimbursement is generated. Therefore, in order to prevent the user from conducting repeated reimbursement, the ticket owned by the user needs to be destroyed after reimbursement of the user, and in view of the characteristics of the block chain UTXO model, that is, the characteristics that the ticket does not exist after transaction, the UTXO model can be applied to the reimbursement of the ticket, that is, after reimbursement, the ticket of the user does not exist or the user does not have the authority of the ticket, so that the occurrence of repeated reimbursement is prevented.

Based on the above analysis and consideration, the embodiment of the present application provides a method for reimbursement of bills, in which electronic bills are stored uniformly by block link points, when reimbursement is not performed, a user holding a bill can have the right of possession of the electronic bill, for the user holding a bill, one electronic bill can be regarded as an asset of the user, when the user requests reimbursement, the user needs to request the block link points to transfer the right of possession of the reimbursement bill to the reimbursement mechanism, that is, the user can deal the reimbursement bill to the reimbursement mechanism once initiating reimbursement, conceivably, after reimbursement is completed, the user holding a bill no longer has the right of possession of the reimbursement bill, and cannot use the reimbursement bill that has been reimbursed again, thereby effectively reducing the possibility of reimbursement of bills, the property safety of the reimbursement mechanism is improved.

In addition, considering that a ticket holder may want to request the same electronic ticket to reimburse for different institutions, for example, the user purchases medical insurance of different insurance companies, and the amount of the medical invoice issued by the medical institution may be on one electronic ticket and cannot be provided to two insurance companies for reimbursement, in this embodiment of the application, the ticket holder may request the block link point to split a ticket into a plurality of sub-tickets in advance before submitting the reimbursement request, and the ticket content of the sub-ticket is the same as the original ticket before splitting except the amount of the ticket, so that the ticket holder may select the sub-ticket needing reimbursement after submitting the reimbursement request and initiate the reimbursement application to the corresponding reimbursement institution.

In the embodiment of the application, in order to improve the efficiency of bill reimbursement, for the sub-bills obtained by splitting, the ticket holding user can also initiate reimbursement application to the reimbursement mechanism in parallel, namely, the ticket holding user selects the sub-bills required to be reimbursed when initiating the application, selects the reimbursement mechanism corresponding to each sub-bill, and after submitting the reimbursement request, the corresponding reimbursement request can be respectively initiated to each reimbursement mechanism, so that the parallel reimbursement of the sub-bills is realized, the operation required for reimbursement of the bills of the user is simplified, and the efficiency of bill reimbursement is.

After introducing the design concept of the embodiment of the present application, some simple descriptions are provided below for application scenarios to which the technical solution of the embodiment of the present application can be applied, and it should be noted that the application scenarios described below are only used for describing the embodiment of the present application and are not limited.

It should be noted that, although only one terminal device 101 is shown in fig. 1, in an actual application, there may be many terminal devices 101 installed with the application or capable of opening the website, and therefore, the terminal device 101 may be any one of the terminal devices 101.

The billing system device 104 may be a device of a billing authority and the billing system device 104 may include one or more processors 1041, memory 1042, I/O interface 1043, and the like. The memory 1042 may store program instructions of a method to be executed by the billing system in the ticket reimbursement method provided in the embodiment of the present application, that is, the user makes a ticket, and when the processor 1041 executes the program instructions, the method to be executed by the billing system in the ticket reimbursement method provided in the embodiment of the present application may be implemented, so as to help the user make a ticket. In addition, the billing system device 104 may be configured with a database, which may be used to store information such as the identification of the bill (e.g., unique identification of the invoice) obtained from the tax authority, and information such as the billing history processed for each user.

In the billing system device 104, an application related to billing is installed or a website related to billing is opened, and when a billing request initiated by the terminal device 101 is received, the billing request is processed by using the billing processing logic of the application or the website, so that necessary information required for billing is provided to the blockchain node 103 for billing, or after the billing is completed, the billed ticket is provided to the blockchain node 103 for storage.

In the blockchain network, a plurality of node devices are included, and functions of the node devices may be identical, or each node device may have different division of labor, for example, part of the node devices are used for recording of ticket circulation, and part of the node devices are used for storing tickets, or part of the node devices can simultaneously implement recording of ticket circulation and storing of tickets. The block chain node 103 may be any node device in a block chain network, and the block chain node 103 may include one or more processors 1031, a memory 1032, and I/O interfaces 1033, etc. The memory 1032 may store program instructions of a method to be executed by the block chain node in the ticket reimbursement method provided in the embodiment of the present application, that is, when the program instructions are executed by the processor 1031, the method to be executed by the block chain node in the ticket reimbursement method provided in the embodiment of the present application may be implemented.

In the billing process, the block chain node 103 may obtain and store the invoiced ticket from the billing system device 104; alternatively, the blockchain node 103 may obtain necessary information required for making a ticket from the billing system device 104, thereby making a ticket based on the information and storing it.

In addition, the invoice reimbursement system 102 may also be configured with a database that may be used to store reimbursement-related audit information, ticketed customer information, and reimbursement history processed for each customer.

In the invoice reimbursement system device 102, an application related to invoice reimbursement is installed or a website related to invoice reimbursement is opened, and when a invoice reimbursement request initiated by the terminal device 101 is received, the invoice reimbursement request can be processed by using invoice reimbursement processing logic of the application or the website (that is, a function implemented by the invoice reimbursement system in the invoice reimbursement method provided in the embodiment of the present application), so as to complete reimbursement of the invoice.

In the bill reimbursement process, the block chain node 103 may transfer the right of possession of the to-be-reimbursed bill from the ticket holding user to the reimbursement mechanism based on the request of the terminal device 101 or the invoice reimbursement system device 102, so that the reimbursement mechanism can obtain the to-be-reimbursed bill for reimbursement, and the ticket holding user loses the right of possession of the to-be-reimbursed bill after the transfer, thereby failing to perform secondary reimbursement, and preventing the occurrence of repeated reimbursement.

The devices that need to communicate with each other may be communicatively connected through one or more networks 105, where the network 105 may be a wired network, or may also be a WIreless network, for example, the WIreless network may be a mobile cellular network, or may be a WIreless-Fidelity (WIFI) network, and certainly, other possible networks may also be used, which is not limited in this embodiment.

As for the circulation flows of issuing or reimbursing bills and the like, generally, the circulation flows need to be monitored by relevant monitoring agencies (such as a tax bureau and the like), each circulation flow of bills needs to be monitored by the tax agency equipment 204, correspondingly, the block chain network can also be provided by the tax agency and used for executing circulation operations of issuing bills and storing bills and the like, and each operation performed on bills in the block chain node, such as the operation of issuing bills, transferring invoices or splitting bills and the like, needs to be accessed through an interface provided by the tax agency equipment 204, namely, needs to be forwarded through the tax agency equipment 204. The terminal device 201, the invoice reimbursement system device 202, the invoicing system device 203, and the block chain node 205 may all correspond to the terminal device 101, the invoice reimbursement system device 102, the invoicing system device 104, and the block chain node 103 in the application scenario shown in fig. 1 in sequence, and therefore, the functions that can be implemented by the above devices may correspond to the devices shown in fig. 1 in sequence, and the difference is that the interaction with the block chain node 205 needs to be performed by the taxation mechanism device 204, so the functions that can be implemented by the above devices may refer to the description of the embodiment part shown in fig. 1, and are not described herein again.

The tax administration device 204 may set a management scope according to the layout of the tax system in each region, for example, a provincial tax administration is generally used to manage tax-related affairs in province, and then the bill affairs belonging to a reimbursement institution or an invoicing institution in province may be forwarded through the provincial tax administration device, or a city tax administration is generally used to manage tax-related affairs in city, and then the bill affairs belonging to a reimbursement institution or an invoicing institution in city may be forwarded through the city tax administration device.

The network for communication among the terminal device 201, the invoice reimbursement system device 202, the invoicing system device 203, and the tax administration device 204 may be the same as the network for communication among the tax administration device 204 and the block link point 205, for example, both may be a mobile cellular network or a wired network, of course, the network for communication among the terminal device 201, the invoice reimbursement system device 202, the invoicing system device 203, and the tax administration device 204 may be the same as the network for communication among the tax administration device 204 and the block link point 205, for example, the network for communication among the terminal device 201, the invoice reimbursement system device 202, the invoicing system device 203, and the tax administration device 204 may be a wide area network, and the network for communication among the tax administration device 204 and the block link point 205 may be a local area network inside the tax administration system.

Of course, the method provided in the embodiment of the present application is not limited to be used in the application scenario shown in fig. 1 or fig. 2, and may also be used in other possible application scenarios, and the embodiment of the present application is not limited. Functions that can be implemented by each device in the application scenario shown in fig. 1 or fig. 2 will be described together in the following method embodiment, and will not be described in detail herein.

In the embodiment of the application, before the reimbursement of the ticket, a general user needs to apply for issuing the ticket to the issuing organization, so that the reimbursement can be performed based on the issued ticket. Therefore, before describing the ticket reimbursement method of the embodiments of the present application, a description will be given of the process of issuing a ticket. As shown in fig. 3, a flow diagram for billing a user for a billing agency is shown.

Step 301: the terminal equipment sends a first billing request to a billing system of the billing mechanism, and the billing system equipment receives the first billing request.

In the embodiment of the application, after the user conducts the transaction or the consumption, the user can request the invoicing mechanism to invoice for the invoicing mechanism according to an invoicing mode provided by the invoicing mechanism (namely, a merchant or a business where the user conducts the transaction or the consumption).

Specifically, if the user performs the transaction on line, a button for issuing a bill is generally provided when the transaction occurs or after the transaction is completed, and the user can enter a bill issuing interface to perform a subsequent invoice issuing process by operating the button for issuing the bill. Fig. 4 is a schematic diagram illustrating an operation of applying for issuing a bill for a user, and fig. 4 illustrates an example of requesting a merchant to issue an invoice after purchasing a commodity through an online shopping platform. In the order detail page, the user can check the detailed content of the transaction order and the invoicing button for applying invoicing, and after the user operates the invoicing button, the user can enter the invoicing information filling page.

In the invoicing information filling page, the user may fill in necessary invoicing information, such as information of the invoice type, the invoice heading, the invoice content, the information of the invoice taker, and the like, and certainly, other possible information may also be included, which is not limited in this application embodiment. The invoice types can generally comprise electronic common invoices and value-added tax special invoices; the invoice head-up can be a person or a unit generally, and when the invoice needs to be reimbursed, the invoice head-up is a reimbursement mechanism (namely a reimbursement enterprise) generally; the invoice content can generally comprise commodity details, commodity types and the like and is used for indicating commodity related information; the information of the payee is generally information of a user holding the invoice, and the information of the payee may include, for example, a user identifier (such as an identification number) of the payee and a contact manner (such as a mobile phone number or a mailbox) of the payee, and the information of the payee may be used to notify the payee according to the information of the payee after the invoice is issued, or the information of the payee is associated with the issued invoice, so that the subsequent payee may query the invoice in its name by the own user information.

After the user fills the billing information, the user can operate the 'submit' button to issue the billing process, correspondingly, the terminal device can detect the billing operation of the user and inform the online shopping platform application of the billing operation, the online shopping platform can respond to the billing operation instruction and send a first billing request to the billing system device, and the first billing request can carry billing information required by the billing bill, namely information filled in the billing information filling page by the user.

Certainly, when the transaction is performed on line, the user can request the transaction party to make a bill in the transaction process besides requesting the transaction party to make a bill after the transaction is successful, for example, the user applies for the other party to make an electronic bill in the process of initiating a transaction application.

Specifically, if the user performs the transaction on line, the billing request may be initiated on line. For example, a merchant of offline transaction can provide an entrance of an invoicing page such as an invoicing two-dimensional code or an invoicing applet code, and a user can enter the invoicing page after scanning the invoicing two-dimensional code or the invoicing applet code, and can initiate an invoicing request after filling in invoicing information; alternatively, the user may also enter a merchant website or application requesting invoicing.

In this embodiment of the application, in order to facilitate subsequent reimbursement of the user, the user may further request the billing mechanism to make a plurality of tickets for the one-time transaction, where the total amount of the plurality of tickets is the total amount of the one-time transaction, correspondingly, the billing operation instruction of the user is used to instruct to make a plurality of tickets for the one-time transaction, and the generated first billing request may include a first billing sub-request corresponding to each ticket to be made. Specifically, when the user fills in the billing information, the billing information of each to-be-billed bill of the to-be-billed bills to be billed can be respectively filled, so that the first billing sub-requests corresponding to the to-be-billed bills are respectively generated according to the billing information and the amount of money of the to-be-billed bills, and are sent to the billing system.

Step 302: and the billing system equipment sends a second billing request to the block chain node, and the block chain node receives the second billing request.

In the embodiment of the application, after the billing system device of the billing mechanism receives the first billing request, billing can be performed for the user based on the billing information request block chain node carried by the first billing request.

Specifically, when an issuing authority claims a ticket from a tax authority in advance, when issuing an electronic ticket, the issuing authority claims an identification section, usually a ticket, that is, a ticket code issued to the issuing authority can only be used by the issuing authority for issuing the ticket. Thus, after the invoicing system device receives the first invoicing request, the invoicing information in the first invoicing request can be verified, for example, whether the commodity is consistent with the commodity in the order requesting the invoicing or whether the user-selected type of ticket can be issued or not, when the verification is passed, one of the ticket identifications can be distributed to the first invoicing request from the claimed identification section, a second invoicing request is generated based on the invoicing information carried by the first invoicing request and the distributed ticket identification, and the generated second invoicing request is sent to the block chain node.

Specifically, when the billing organization does not claim the ticket in advance, the ticket identifier cannot be allocated to the received first billing request, so after the billing system device receives the first billing request and verifies the first billing request, the billing system device may generate a second billing request based on the billing information carried in the first billing request, and send the generated second billing request to the block chain node.

In practical application, the invoicing system device sends the second invoicing request to the block chain node, and the invoicing request can be sent to the block chain node by the invoicing system device through the tax mechanism device. When the billing system equipment does not distribute the bill identification, the bill identification can be distributed through the tax institution equipment, and the billing information carried in the second billing request and the distributed bill identification are sent to the block chain node.

The ticket identifier is used to uniquely identify a ticket, for example, in the case of an invoice, the ticket identifier may be a unique identification code of the invoice.

The billing system device may send a second billing request to a blockchain node in the blockchain network. Generally, a blockchain node here may be any blockchain node in a blockchain network, and may also be a blockchain node in fixed communication connection with an invoicing system device.

In the embodiment of the application, when a user applies for making a plurality of bills for one transaction, the billing system equipment can respectively process the first sub-billing requests corresponding to the plurality of bills, that is to say, the processing process of each first sub-billing request is the same as that of the first billing request; of course, the processing can also be performed separately and forwarded to the blockchain node for processing.

Step 303: the blockchain node issues the ticket for the user based on the second billing request.

In this embodiment, the block link point may issue a ticket for the user based on the billing information and the like carried by the second billing request, that is, bill the user.

Specifically, when the second billing request carries the allocated ticket identifier, the blockchain node issues the ticket for the user, and the billing information and the ticket identifier may be used as the ticket data of the ticket and stored in the blockchain.

Specifically, the block link point may be used as a bill storage device approved by the tax authority, and also may refer to a bill from the tax authority in advance, and if the second billing request does not carry the distributed bill identifier, then the block link node issues the bill for the user, and the block link node may distribute the bill identifier for the bill with the opening tool, and link up the billing information and the bill identifier as the bill data of the bill, that is, store the bill in the block link.

When a block link point links the bill content, it is generally required that the block link point broadcasts the bill content to other nodes in a block link network, and when the block link points achieve consensus through a consensus mechanism, a block is generated based on the bill content and linked to the previous block to form a block chain. When generating a block based on the ticket content, in order to facilitate subsequent operations such as verification or query on the ticket content, a hash (hash) value is generally generated according to the ticket content and used as an identification identifier of the ticket, and when subsequently verifying or querying the ticket, verification or query can be performed according to the identification identifier. Of course, the ticket may also include other extended contents (i.e., contents not included in the actual contents of the ticket), such as the reimbursement status of the ticket or reimburseable money amount, and may also generate a hash value based on all the contents corresponding to the ticket.

Step 304: and the block chain node sends a first billing response message to the billing system equipment, and the billing system equipment receives the first billing response message.

In the embodiment of the application, after the block link node links the ticket data of the ticket, a first billing response message can be returned to the billing system equipment to notify the billing system equipment that the link is successfully linked. The first billing response message can also carry information such as identification marks of the invoiced bills.

Of course, when the block link point fails to link the ticket data of the ticket, a first ticket issuing response message may also be returned to the billing system device to notify the billing system device of the link failure.

Step 305: and the billing system equipment sends a second billing response message to the terminal equipment, and the terminal equipment receives the second billing response message.

In this embodiment, the billing system device may return a second billing response message to the terminal device to notify that the ticket has been issued and the uplink is successful. The second billing response message may also carry information such as the identification of the invoiced ticket, so that the terminal device may prompt the user to view the identification after receiving the second billing response message.

In the embodiment of the present application, after the bill has been issued, the user holding the bill, that is, the user holding the bill, may apply for reimbursement by using the issued bill, and the following description will be specifically directed to the process of reimbursement of the bill. Fig. 5 is a schematic flow chart of ticket reimbursement.

Step 501: the terminal equipment sends a bill query request to the bill query equipment, and the bill query equipment receives the bill query request.

In the embodiment of the application, when a user wants to query a bill, the following query modes can be provided:

first query mode

When the bill inquiring equipment for inquiring the bills is arranged, the bill holding user can inquire all the bills under the name of the user through the bill inquiring equipment. After the user makes a bill, the bill query device can associate the identification mark of the made bill with the user mark and store the association relation between the user mark and the identification mark, and when the user wants to query the bill owned by the user, the user mark of the user can be provided for query.

Specifically, the bill query device may correspond to a dedicated bill query APP or a bill query website, or provide a query interface for other applications, so that the user may query the own bill through the bill query APP or the bill query website, or query the own bill through the query interface of other applications. Fig. 6 is a schematic diagram of an interface for ticket query. Fig. 6 shows an interface diagram of query by a ticket query APP and query by a public number query entry.

When the user inquires through the bill inquiry APP, the user can enter an inquiry page in the bill inquiry APP and select to inquire the bill, so that the user enters the bill inquiry page on the right side in the figure 6. Similarly, when the user queries through the public number query entry, the user may expand the public number query menu and select the ticket query function in the query menu, thereby entering the ticket query page illustrated on the right side in fig. 6.

In the bill query page, a user can input information related to bill query and operate a query button, correspondingly, the terminal equipment can detect the operation of the user and send a corresponding query operation instruction to a bill query APP or an application where a public account is located, so that a corresponding bill query request is generated based on the query operation instruction and is sent to the bill query equipment. The information related to the ticket query may include a type of the ticket, a type of a user identifier (such as a mobile phone number or an identification number) used for querying the ticket, and a specific user identifier.

In this embodiment, the function of the ticket query device may be associated with a tax authority, for example, the ticket query device may be a device belonging to the tax authority, and in a possible implementation, the ticket query device may be a device of the tax authority or a blockchain node in a blockchain network.

Second query mode

After the user knows the identification mark of the bill, the user can directly inquire the bill corresponding to the identification mark through the identification mark. When inquiring through this kind of mode, the user can directly send out the bill inquiry to block chain link point through terminal equipment, and need not to inquire equipment with the help of the bill, of course, also can send out the bill inquiry to block chain link point through bill inquiry equipment.

Step 502: the bill inquiring equipment inquires the identification associated with the user identification.

In the embodiment of the application, the association relation between the user identification and the identification is stored in the bill query device, so that when the bill query device receives a bill query request, the identification associated with the user identification can be queried according to the user identification carried in the bill query request. Of course, when the user specifies the screening condition of the ticket to be queried, for example, the user specifies to query a specific type of ticket, the ticket querying device may also screen the identification obtained by the query.

Step 503: the bill inquiry equipment sends a bill data inquiry request to the block chain nodes, and the block chain nodes receive the bill data inquiry request.

In the embodiment of the application, because the bill data of the bill is stored in the block chain node, the bill query device can generate the bill data query request according to the identification mark obtained by query, and send the bill data query request to the block chain node, so as to obtain the bill data corresponding to each identification mark from the block chain node.

Step 504: and the block chain node sends a bill data query response message to the bill query device, and the bill query device receives the bill data query response message.

Step 505: and the bill query equipment sends a bill query response message to the terminal equipment, and the terminal equipment receives the bill query response message.

In the embodiment of the application, the block link points can inquire corresponding bill data according to the identification marks, carry the inquired bill data in the bill inquiry response message and send the bill inquiry response message to the bill inquiry equipment, and when the bill inquiry equipment receives the bill inquiry response message, can carry the bill data in the bill inquiry response message and return the bill data to the terminal equipment.

After the terminal device obtains the bill data obtained by query, the bill data can be output on a bill query result page so as to be convenient for a user to view. Fig. 7 is a schematic diagram of a ticket query result page 1 and a ticket splitting page. In the bill query result page 1, the bill abstract of each bill obtained by query can be displayed, and when a user wants to query complete bill data, the user can operate a 'check bill' button or operate a corresponding area of the bill to be checked, so as to check detailed data of the bill.

Step 506: the terminal equipment sends a ticket data splitting request to the block chain nodes, and the block chain nodes receive the ticket data splitting request.

In the embodiment of the application, considering the situation that a ticket holding user may want to request the same electronic ticket to reimburse for different institutions, for example, the user purchases medical insurance of different insurance companies, and the amount of medical invoices issued by the medical institutions may be on one electronic ticket and cannot be provided for two insurance companies to reimburse for reimburse, based on the situation, in the embodiment of the application, the ticket holding user may request a block link point to split one ticket into a plurality of sub-tickets in advance before submitting a reimbursement request.

Specifically, when a bill is to be split for holding a bill, the 'splitting bill' button of the bill to be split can be operated in the bill query result page 1, so that the bill splitting page is entered. In the bill splitting page, a bill holding user can select the splitting number and input information such as the amount of money of each sub-bill, and after the input is finished, a 'splitting confirmation' button is operated, so that the terminal equipment responds to a splitting operation instruction of the bill holding user for the issued bill and sends a bill data splitting request to the block chain link points, wherein the bill splitting request carries the identification mark and the splitting indication information of the issued bill, the identification mark of the issued bill is the identification mark of the bill needing to be split selected by the user, and the splitting indication information is the information such as the splitting number and the amount of money of each sub-bill input by the user.

In fig. 7, two sub-tickets obtained by splitting are specifically taken as an example, and certainly, in practical application, a ticket holding user can select the number of sub-tickets to be split according to the own requirement, which is not limited in the embodiment of the present application.

Step 507: and splitting the initial bill into at least two sub-bills according to the indication of the splitting indication information by the block chain link points.

In the embodiment of the application, the initial bill refers to a bill before splitting, and correspondingly, after the initial bill is split, a plurality of sub-bills can be obtained.

After the block chain node receives the bill splitting request, the initial bill can be split according to the indication of the splitting indication information carried by the bill splitting request, and at least two sub-bills are obtained. The process of splitting the initial bill by the block link point can be regarded as a transaction process, the initial bill is output into at least two sub-bills when the transaction is input, and the block link point can be stored again based on the identification marks of the sub-bills obtained by splitting. The bill contents of each sub-bill are the same as the original bill except the bill surface amount, and the block link points can generate the identification marks of each sub-bill according to the bill contents of each sub-bill obtained by splitting, that is, the bill contents of the sub-bills are the same as the original bill in terms of information such as bill unique marks and the like, the only difference is the bill surface amount, and the sum of the bill surface amounts of each sub-bill is the bill surface amount of the original bill.

The identification may be, for example, a hash value generated based on the content of the ticket.

Based on the characteristics of the UTXO model of the block chain, after the splitting is completed, the initial bill does not exist substantially, and the situation that the user can use the initial bill to reimburse the bill and reimburse the bill repeatedly is avoided.

Step 508: and the block chain node sends a bill splitting response message to the terminal equipment, and the terminal equipment receives the bill splitting response message.

When the bill splitting is completed, the block chain node can carry the bill data of at least two sub-bills obtained by splitting in the bill splitting response message and send the bill data to the terminal equipment, and after the terminal equipment receives the bill splitting response message, the bill data of the at least two sub-bills can be displayed on a display interface for a user to check.

Of course, the split sub-note can be actually regarded as an independent note, and the sub-note can also be split to obtain the sub-note of the sub-note.

It should be noted that, in the embodiment of the present application, the steps 506 to 508 are not essential steps, and may be selected according to actual requirements in practical applications. For example, when the user does not need to reimburse for the sub-ticket, the ticket splitting may not be performed.

Step 509: and the terminal equipment generates a bill reimbursement request based on the to-be-reimbursed bill selected by the bill holding user.

In the embodiment of the application, after the terminal equipment receives the bill splitting response message, the bill data of at least two sub-bills can be displayed on the bill query result page. As shown in fig. 8 and 9, both are schematic views of a user selecting a ticket to be issued.

Fig. 8 and 9 illustrate the presentation of the ticket data of two different sub-tickets, respectively.

Specifically, as shown in the ticket query result page 2 in fig. 8, after the ticket is split, a status display of the ticket may be added in the ticket query result page 2 to prompt the user of the status of the ticket, for example, as shown in the ticket query result page 2, the status of the ticket 1 is "split", that is, the ticket 1 is successfully split, and the status of the ticket 2 is "issued", that is, the ticket 2 is successfully issued, but is not split. When the ticket holder wants to make a ticket reimbursement, the ticket to be reimbursed can be selected to enter a ticket reimbursement page.

Here, the example of the ticket holder reimbursing the ticket 1 in the ticket query result page 2 will be described.

As shown in the ticket reimbursement page 1 in fig. 8, when the user only wants to reimburse the sub-ticket 1 in the ticket 1, the user can select only the sub-ticket 1, that is, only the sub-ticket 1 is used as the ticket to be reimbursed, and after the user inputs the corresponding reimbursement mechanism, the user operates the "reimbursement" button to initiate the reimbursement request. Specifically, the terminal device may detect a selection operation instruction of the ticket-holding user, determine the selected sub-ticket as a to-be-reimbursed ticket, and generate a ticket reimbursement request for the to-be-reimbursed ticket according to the reimbursement enterprise selected by the ticket-holding user in response to the ticket reimbursement operation instruction of the ticket-holding user. The ticket reimbursement request may carry an identification of the ticket to be reimbursed, so that the reimbursement institution may determine the ticket to be reimbursed by the ticket holder, and of course, may also carry other information, such as reimbursement institution information.

As shown in the ticket reimbursement page 2 in fig. 8, when the user only wants to reimburse a plurality of sub-tickets in the ticket 1, the user can select the plurality of sub-tickets, for example, the sub-ticket 1 and the sub-ticket 2 are selected in the ticket reimbursement page 2, and after the user inputs the reimbursement mechanisms corresponding to the sub-tickets, the user operates the "reimbursement" button to initiate a reimbursement request. Specifically, the terminal device may detect a selection operation instruction of the ticket holding user, determine the selected sub-tickets as the to-be-reimbursed tickets, that is, the sub-ticket 1 and the sub-ticket 2, and generate a ticket reimbursement request for each to-be-reimbursed ticket according to the reimbursement enterprise selected by the ticket holding user for each to-be-reimbursed ticket in response to the ticket reimbursement operation instruction of the ticket holding user, that is, may generate the ticket reimbursement request 1 and the ticket reimbursement request 2. The ticket reimbursement request corresponding to each sub-ticket can carry the identification mark of the corresponding sub-ticket, so that the reimbursement mechanism can determine the ticket reimbursed by the ticket holder.

Specifically, as shown in the ticket query result page 3 in fig. 9, after the ticket is split, a sub-ticket may be displayed as an independent ticket in the ticket query result page 3. In order to facilitate the ticket holder to distinguish the tickets, the reimburseable amount of each ticket can be displayed in the ticket query result page 3. As shown in the bill query result page 3, the bill unique codes of the sub-bill 1 and the sub-bill 2 are the same, but the reimburseable amount is different, so that the user holding the bill can distinguish the bills according to the reimburseable amount.

When the ticket holder wants to make a ticket reimbursement, the ticket to be reimbursed can be selected to enter a ticket reimbursement page.

For example, when the user wants to submit a cancellation for ticket 1, then sub-ticket 1 can be selected to enter ticket cancellation page 3, and ticket cancellation page 3 can show that "the sub-ticket amount is 60", and after inputting the corresponding cancellation mechanism in ticket cancellation page 3, operate the "cancellation" button to initiate a cancellation request. The terminal equipment can detect the selection operation instruction of the ticket holding user, determine the selected sub-ticket as the to-be-reimbursed ticket, respond to the ticket reimbursement operation instruction of the ticket holding user, and generate a ticket reimbursement request for the to-be-reimbursed ticket according to the reimbursement enterprise selected by the ticket holding user.

Or, when the user wants to reimburse the ticket 2, the user may select the ticket 2 to enter the ticket reimbursement page 4, and the ticket reimbursement page 4 may display "the ticket amount is 500" and operate the "reimbursement" button to initiate a reimbursement request after inputting the corresponding reimbursement mechanism in the ticket reimbursement page 4. The terminal equipment can detect the selection operation instruction of the ticket holding user, determine the selected ticket as the ticket to be reimbursed, respond to the ticket reimbursement operation instruction of the ticket holding user, and generate a ticket reimbursement request for the ticket to be reimbursed according to the reimbursement enterprise selected by the ticket holding user.

As shown in fig. 10, the operation of reimbursing a plurality of tickets for the ticket holder is schematically illustrated. When a ticket holder wants to simultaneously claim a plurality of tickets, a plurality of tickets can be selected in the ticket query result page 3, and the sub-ticket 1 and the sub-ticket 2 are selected as shown in 10. Specifically, the bill query result page 3 can initially display a bill selection box, and a user holding the bill can directly operate the selection box to select the bill; or, the ticket query result page 3 may not display the ticket selection frame initially, and after the ticket holding user performs a predetermined operation on the selection frame, for example, long-time pressing, the selection frame is displayed in the ticket query result page 3, and the ticket holding user operates the selection frame to select the ticket. After the ticket holding user selects the ticket, the operation of applying for reimbursement can be carried out, the terminal equipment can detect the selection operation instruction of the ticket holding user, the selected ticket is determined as the ticket to be reimbursed, the terminal equipment jumps to the ticket reimbursement page 5, and after the ticket holding user can input reimbursement mechanisms corresponding to the tickets in the ticket reimbursement page 5, the terminal equipment operates a reimbursement button to initiate a reimbursement request. The terminal equipment can respond to the bill reimbursement operation instruction of the ticket holding user and respectively generate a bill reimbursement request for each to-be-reimbursed bill according to the reimbursement enterprise selected by the ticket holding user for each to-be-reimbursed bill.

Step 510: the terminal equipment sends a bill reimbursement request to the bill reimbursement system, and the bill reimbursement system equipment receives the bill reimbursement request.

After the terminal device generates the ticket reimbursement request, the generated ticket reimbursement request can be sent to the ticket reimbursement system.

When the ticket holder selects only one ticket to be reimbursed, the ticket reimbursement request can be sent to a ticket reimbursement system of a reimbursement mechanism selected for the ticket by the ticket holder, as shown in a ticket reimbursement page 1 in fig. 8, the terminal equipment can send the ticket reimbursement request to a ticket reimbursement system of an enterprise A to request the enterprise A to reimburse the amount of the ticket 1 for the ticket holder; when the ticket checking user selects a plurality of tickets to be checked out, the ticket checking request can be respectively sent to the ticket checking system of the checking mechanism selected by the ticket checking user for each ticket, as shown in a ticket checking page 2 in fig. 8, the terminal device can respectively send the ticket checking requests of the sub-ticket 1 and the sub-ticket 2 to the ticket checking system of the enterprise a and the ticket checking system of the enterprise B, so as to respectively request the enterprise a to check out the amount of the ticket 1 for the ticket checking user and request the enterprise B to check out the amount of the ticket 2 for the ticket checking user, thereby realizing parallel checking out of the tickets and improving the ticket checking efficiency.

Step 511: the terminal equipment sends a ticket data transfer request to the block chain nodes, and the block chain nodes receive the ticket data transfer request.

In the embodiment of the present application, the terminal device sends a ticket transfer request to the block link node, and may include various embodiments.

First mode

Step 5111: and the terminal equipment sends a ticket data transfer request to the block chain nodes.

As shown in step 5111 in fig. 5, the terminal may send a ticket reimbursement request to the ticket reimbursement system before sending the ticket reimbursement request to the ticket reimbursement system, or the terminal may send a ticket transfer request to the blockchain node actively after sending the ticket reimbursement request to the ticket reimbursement system to request the blockchain node to transfer the right of possession of the ticket to be reimbursed from the ticket holder to the reimbursement authority.

Second mode

Step 5112: and the terminal equipment receives a bill data acquisition request sent by the bill reimbursement system equipment.

Step 5113: and the terminal equipment sends a ticket data transfer request to the block chain nodes.

After the terminal device sends the ticket reimbursement request to the ticket reimbursement system, as shown in steps 5112 and 5113 in fig. 5, since the ticket reimbursement system device does not possess the right of holding the ticket to be reimbursed, the ticket reimbursement system device may send the ticket data acquisition request to the terminal device, or alternatively, the ticket reimbursement system device may attempt to acquire the ticket content of the ticket to be reimbursed to the block link point, and send the ticket data acquisition request to the terminal device when the ticket content acquisition fails. The terminal device may send a ticket transfer request to the block link point after receiving the ticket content acquisition request, so as to request the block link point to transfer the right of possession of the to-be-reimbursed ticket from the ticket holding user to the reimbursement mechanism.

In the first mode or the second mode, after the right of possession of the to-be-reimbursed ticket is transferred successfully, the block link point may send a response message indicating that the transfer is successful to the terminal device, so that the terminal device may notify the ticket reimbursement system device to start executing a subsequent reimbursement process.

Third mode

Step 5114: and the terminal equipment sends authorization indication information to the bill reimbursement system.

Step 5115: the bill reimbursement system equipment sends a bill transfer request to the block link points.

As shown in steps 5114 and 5115 in fig. 5, the terminal device may send authorization indication information authorizing to transfer the right of holding of the to-be-reimbursed ticket to the ticket reimbursement system at the same time or after sending the ticket reimbursement request to the ticket reimbursement system, so that when the ticket reimbursement system device obtains the authorization indication information, it may send a ticket data transfer request to the block link point according to the authorization indication information to request the block link point to transfer the right of holding of the to-be-reimbursed ticket from the ticket holding user to the reimbursement mechanism.

The authorization indication information can be carried in the bill reimbursement request and sent to the bill reimbursement system.

In a third mode, after the ownership of the transfer to-be-reimbursed bill is successful, the block link point may directly send a response message indicating that the transfer is successful to the bill reimbursement system device.
