Optionally, an reimbursement document triggered by the mobile application is obtained, where the mobile application is an application program running on the mobile terminal. In this embodiment, the mobile application may specifically be an application program corresponding to an electronic ticket public server. The reimbursement document is a document provided by a user when the user needs to reimburse a superior level for resource reimbursement, and specifically may include reimbursement data and a corresponding resource transfer credential. The reimbursement data may be a detailed list of the resources to be reimbursed, including the category to which the resources belong (such as transportation fees, lodging fees, dining fees, and the like), the resource transfer share, the reimburser and reimbursement account, the time and place of resource transfer, and the like. The resource transfer voucher is a reimbursement voucher such as an electronic ticket or an electronic ticket billing inquiry code.

An electronic ticket is a ticket that is stored electronically, such as may be stored in a storage medium or computer device. The electronic bill billing inquiry code is used for inquiring the electronic bill and is only corresponding to the electronic bill. The electronic bill billing inquiry code can be specifically a character string, a two-dimensional code or a bar code and the like. The electronic bill comprises an electronic bill billing inquiry code.

Specifically, the receiver device can receive an reimbursement document triggered by the mobile application, wherein the reimbursement document comprises an electronic bill invoicing query code. In one embodiment, the reimbursement document may be generated by the mobile application and triggered for transmission to the recipient device by the mobile application. Or the mobile application acquires the reimbursement bill stored in the mobile terminal and then sends the reimbursement bill to the equipment of the receiving party.

In one embodiment, the user may save the electronic ticket through the electronic ticket public server after receiving the electronic ticket issued by the issuing party. The user is in the role of a consumer at this time, and the user can log in the mobile application through the consumer identification (i.e., the user identification) to view the electronic ticket associated with the consumer identification. Wherein, the electronic bill public server is used for providing public storage service of electronic bills originated from block link points.

In one embodiment, the mobile application may provide a variety of reimbursement document templates for use by the user, and the consumer may select a ticket template designated by the electronic ticket recipient for the completion of reimbursement data. Further, the user can select the resource transfer voucher of the current to-be-checked resource through the mobile application, such as selecting a corresponding electronic bill or simply selecting an electronic bill billing inquiry code. The mobile application obtains the electronic bill selected by the user from the electronic bill public server, and further, the mobile application can generate the reimbursement bill according to reimbursement data filled by the user and the resource transfer voucher.

In another embodiment, the generating of the reimbursement document comprises: the electronic bill public server acquires reimbursement data; the electronic bill public server searches an electronic bill billing inquiry code corresponding to the reimbursement data; and the electronic bill public server generates an reimbursement bill according to the reimbursement data and the electronic bill invoicing query code.

Specifically, the mobile application may display an reimbursement data filling interface, and the user enters corresponding reimbursement data in the reimbursement data filling interface. And the mobile application transmits the recorded reimbursement data to the electronic bill public server. And after receiving the reimbursement data, the electronic bill public server searches for an electronic bill invoicing query code which is associated with the user identification and corresponds to the reimbursement data at the electronic bill public server. And the electronic bill public server generates an reimbursement bill according to the reimbursement data and the electronic bill invoicing query code. The electronic ticket public server delivers the reimbursement document to the recipient device.

In one embodiment, the electronic bill public server can search the electronic bill which is associated with the user identification and corresponds to the reimbursement data at the electronic bill public server side, and generate the reimbursement bill according to the reimbursement data and the electronic bill invoicing query code.

In one embodiment, after the electronic bill public server generates the reimbursement document, the reimbursement document can be sent to the mobile application, and the reimbursement document can be viewed by the user through an interface displayed by the mobile application. And after receiving the reimbursement instruction triggered by the mobile application, the electronic bill public server sends the reimbursement document to the equipment of the receiving party.

In the embodiment, the mobile application is triggered, the electronic bill public server generates the reimbursement bill conveniently and quickly, and the operations of manually printing the bill, pasting the invoice and the like by a user are not needed, so that the reimbursement efficiency is greatly improved, and the reimbursement cost is saved.

In one embodiment, step S202 includes: when the mobile application triggers the reimbursement bill and reports the reimbursement bill to the electronic bill public server, receiving the reimbursement bill transmitted by the electronic bill public server; wherein, the electronic bill public server is used for providing public storage service of electronic bills originated from the block link point.

Specifically, after the mobile application triggers the reimbursement document and reports it to the electronic ticket public server, the electronic ticket public server may send the reimbursement document to the recipient device. The recipient device receives an reimbursement document delivered through the electronic ticket public server. Therefore, the reimbursement bill can be directly transmitted through the electronic bill public server for storing the electronic bill, the electronic bill can be conveniently and quickly acquired, and the electronic bill can be transmitted.

S204, according to the electronic bill billing inquiry code, searching the electronic bill corresponding to the electronic bill billing inquiry code from the block chain node in the block chain network.

Wherein, the block chain node is a data processing node in the block chain network. A blockchain network is a carrier and organization of the operation blockchain technology. The block chain technology, BT (block chain technology) for short, also called distributed book technology, is an internet database technology, and is characterized by decentralization and public transparency, so that everyone can participate in data recording. The blockchain technology is a brand new distributed infrastructure and computing mode that uses blockchain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, uses cryptography to secure data transmission and access, and uses intelligent contracts composed of automated script codes to program and manipulate data. In this embodiment, an electronic ticket is stored on a blockchain node in a blockchain network.

Specifically, the receiver device may search the electronic ticket corresponding to the electronic ticket billing query code from the blockchain node in the blockchain network according to the electronic ticket billing query code, and acquire the searched electronic ticket.

In one embodiment, there may be blockchain nodes in the blockchain network that correspond to the recipient device, which may provide an Interface for data communication with the recipient device, such as a Development sdk (Software Development Kit) and api (Application Programming Interface) Interface. And the receiving party equipment acquires the electronic bill corresponding to the electronic bill billing inquiry code from the block chain node by calling the corresponding interface. When the block chain node has the electronic bill corresponding to the electronic bill billing inquiry code, the electronic bill billing inquiry code is correct and not forged.

In one embodiment, the electronic ticket may be pre-generated and stored in a blockchain node in a blockchain network. The electronic bill can be generated through the block chain nodes and stored correspondingly, or can be generated by other equipment and uploaded to the block chain nodes for storage.

And S206, checking the reimbursement bill according to the searched electronic bill.

Specifically, the receiver device may check the reimbursement document according to the found electronic ticket. In one embodiment, when the electronic bill corresponding to the electronic bill billing inquiry code exists in the blockchain node, the fact that the electronic bill provided by the consumer really exists is indicated.

In one embodiment, the electronic ticket includes a ticket status that the recipient device can verify. For example, when the ticket status of the electronic ticket is "issued, not reimbursed", the receiving device may perform the next data check. When the bill state of the electronic bill is 'issued and reimbursed', the electronic bill is declared to have completed reimbursement and cannot be reimbursed.

In one embodiment, where the electronic ticket is included in the reimbursement document, the recipient device may also check for consistency of the electronic ticket in the reimbursement document based on the electronic ticket found from the blockchain network. When the found electronic bill checks that the electronic bill in the reimbursement bill is consistent, the receiving party equipment can continuously audit reimbursement data in the reimbursement bill. For example, whether the generation time of the electronic bill is consistent with that of the reimbursement bill, whether the category (for example, transportation fee, lodging fee or catering fee) of the resource in the electronic bill is consistent with that of the reimbursement bill, and the like.

And S208, after the reimbursement bill passes the checking, transferring resources according to the reimbursement bill.

Specifically, after the receiver device checks the data in the reimbursement document according to the check item, the checked reimbursement document is real and legal and meets reimbursement terms inside the receiver device, and the receiver device can perform corresponding resource transfer according to information such as reimbursers, reimbursement accounts, resource transfer shares and the like in the reimbursement document.

And S210, after the resources are transferred successfully, triggering the updating of the bill information of the electronic bill, and recording the updated bill information to a block chain node in the block chain network.

The bill information is information used for generating an electronic bill, and comprises an electronic bill identifier, a bill state, a billing party identifier, a receiving party identifier, a resource transfer share and the like. The electronic bill identification is used for uniquely identifying an electronic bill, and specifically can comprise a bill code and a bill number of the electronic bill. The bill status is used for indicating that the current electronic bill is in a specific stage in the whole bill cycle, such as an opened state, a reimbursed state, an unannounced state, a tax reimbursed state, an unrenounced state and the like. Wherein, the electronic bill is in the opened state to show that the electronic bill is generated; the electronic bill is in a reimbursed state, which indicates that the electronic bill has completed reimbursement for one time; the electronic bill is in the tax declared state, which indicates that the receiver of the electronic bill completes one tax declaration according to the electronic bill.

The invoicing party identifier is an identifier corresponding to the device initiating the invoicing request and is used for uniquely identifying the invoicing party. The invoicing party may be a selling enterprise, and the invoicing party needs to provide a consumption certificate, i.e. an electronic bill, for the consumer when selling goods, providing services or engaging in other business activities. The invoicing party identification can be specifically a name of a seller, a taxpayer identification number of the seller, an account number of the seller for opening an account, and the like.

The receiver identification is used for uniquely identifying the electronic bill receiver. The recipient may specifically be an individual or a business. After an individual or a business consumes at a sales business, the sales business can provide a consumption certificate, namely an electronic bill, for a consumer. The receiver identification may specifically be a name of the purchaser, a taxpayer identification number of the purchaser, or an account number of the purchaser. The resource transfer share is the specific share of the resource consumed by the consumer.

Specifically, after the resource transfer is successful, the receiving device may trigger the update of the ticket information of the electronic ticket, mainly trigger the update of the ticket state in the ticket information, and further trigger the recording of the updated ticket information to the block chain node in the block chain network. That is, when the resource transfer is successful, the ticket status of the electronic ticket is updated to the reimbursed status, and the updated information indicating that the electronic ticket is in the reimbursed status is stored in the uplink.

In one embodiment, the step of triggering the update of the ticket information of the electronic ticket and triggering the recording of the updated ticket information to the blockchain node in the blockchain network specifically includes: sending a bill information updating request to an electronic bill public server; the bill information updating request is used for indicating the electronic bill public server to update the bill state in the bill information of the electronic bill to the reimbursed state and uploading the updated bill information to the block chain node; wherein, the electronic bill public server is used for providing public storage service of electronic bills originated from block link points.

Specifically, when the resource transfer is successful, the receiving device sends a bill information update request to the electronic bill public server. The electronic bill public server can send a confirmation request to the user after receiving the bill information updating request, and when receiving confirmation information which is triggered by the user and indicates that the resource transfer is successful, the electronic bill public server updates the bill state in the bill information of the electronic bill to a reimbursed state and uploads the updated bill information to the block chain nodes in the block chain network.

In one embodiment, there may be a blockchain link point in the blockchain network that corresponds to the electronic ticket common server. When the electronic bill public server intends to write data into the block chain network, the data can be directly transmitted to the block chain link points through the interfaces provided by the corresponding block chain link points, and the data is written into the data block after the block chain link points are identified with other block chain link points in the block chain nodes. The data block is a memory module for storing data in a block link point.

In one embodiment, the block link node receives the updated ticket information, generates an electronic ticket reimbursement inquiry code corresponding to the updated ticket information, updates the electronic ticket according to the updated ticket information and the electronic ticket reimbursement inquiry code, and writes the updated electronic ticket into the data block after reaching consensus in the block chain network. Therefore, after the resource transfer is successful, the bill state of the electronic bill can be correspondingly updated, and the updated information can be stored in a chain manner, so that the circulation information of the electronic bill can be shared among all roles through the block chain network, and the latest state of the electronic bill can be inquired in real time through the block chain network.

Common consensus algorithms in the blockchain network include POW (Proof of Work), POS (Proof of interest), DPOS (guaranteed Proof of interest), PBFT (Practical Byzantine Fault-tolerant algorithm), and the like.

The consensus algorithm employed in one particular embodiment is specifically a consensus algorithm (Bft-Raft) based on a consensus algorithm (e.g., raft) and a Byzantine fault-tolerant algorithm (e.g., bft). Of course, other consensus algorithms may be adopted in other embodiments of the present invention, and the embodiments of the present invention are not limited herein.

For example, FIG. 3 shows a schematic diagram of the consensus algorithm in one embodiment. Referring to fig. 3, a Client (Client, specifically, a blockchain electronic invoice application platform as shown in fig. 8) initiates a consensus Request (Request) and sends the consensus Request to a blockchain node (master node Leader a) in a leading state. And the block chain nodes in the leader state are obtained by jointly electing each block chain link point in the block chain network. Continuing to enter an application Entity stage, broadcasting the consensus content (or intermediate data obtained after processing the consensus content) corresponding to the consensus request to other block chain nodes (following nodes, namely, follower B, follower C and Follower D …) which are not in a Leader state in the block chain network by the Leader A; continuing to enter an application Response stage, broadcasting the received consensus content to other blockchain nodes by each slave node, entering a Commit stage when the consensus content broadcast by the other blockchain nodes with the preset number (2f + 1) is received to be consistent, and feeding back the confirmation result to the master node by each slave node. And when the master node receives the feedback confirmation of other block link points with the preset number (2f + 1), judging that the result of the consensus feedback (Reply) to the Client is completed. Wherein, 3f +1 is less than or equal to N, and N is the number of block chain nodes in the block chain network. f is the number of bad blockchain nodes in the blockchain network.

As will be described in detail below with reference to the embodiments of the present application, when the electronic ticket public server uploads the updated ticket information to the block chain node, that is, the updated ticket information is intended to be written into the data block in the block chain network, the event that needs to be agreed upon is written into the electronic ticket public server. When the block chain node corresponding to the electronic bill public server is the block chain node in the leading state, the block chain node broadcasts the event needing to achieve the consensus to other block chain nodes in the block chain network.

After receiving the event needing to be agreed, the blockchain nodes which are not in the leading state broadcast the received event needing to be agreed to other blockchain nodes in the blockchain network. In this way, each block link point in the block chain network enters a confirmation stage when receiving the data broadcast by the preset number of other block chain nodes and being consistent, so as to prevent the cheating behavior of the block chain node in the leading state. And feeding back the confirmation result to the block chain nodes in the leading state after the confirmation is finished, judging that the consensus is finished on the event needing to be achieved when the block chain nodes in the leading state receive the feedback confirmation of the preset number of other block chain nodes, and writing the data corresponding to the event achieving the consensus into the data block by the block chain nodes.

When the block chain link point corresponding to the electronic bill common server is not the block chain link point in the leader state, the event needing to achieve consensus is forwarded to the block chain node in the leader state, and the block chain link point in the leader state is used for leading the consensus process in the previous steps. And the block chain nodes in the leader state are obtained by jointly electing each block chain link point in the block chain network.

The data processing method of the electronic bill obtains the reimbursement bill which can be triggered by the mobile application and comprises the electronic bill billing inquiry code, and can directly search the electronic bill corresponding to the electronic bill billing inquiry code from the block link points according to the electronic bill billing inquiry code. Because the data on the block chain network has extremely high safety and reliability, the authenticity of the searched electronic bill can be ensured. And then checking the reimbursement bill according to the found electronic bill, transferring resources according to the reimbursement bill after the reimbursement bill passes the checking, triggering the updating of the bill information of the electronic bill, and triggering the recording of the updated bill information to the block link point, so that the reimbursement state of the invoice can be effectively recorded, and the repeated reimbursement is avoided. Therefore, the consumer can trigger the reimbursement process at the mobile terminal, the paper invoice does not need to be pasted on the reimbursement bill in the whole reimbursement process to be reimbursed, paperless operation is completely realized, invoice reimbursement efficiency is improved, and invoice reimbursement cost is saved.

In one embodiment, as shown in fig. 4, step S206, that is, the step of checking the reimbursement receipt according to the found electronic bill specifically includes the following steps:

s402, acquiring a ticket symmetric key corresponding to the electronic ticket.

The ticket symmetric key is a key of the electronic ticket and is a symmetric key. And encrypting the bill information by using the bill symmetric key to obtain a bill ciphertext, and decrypting the bill ciphertext by using the bill symmetric key to obtain the bill information.

In one embodiment, the block chain node can randomly generate a bill symmetric key corresponding to the bill information after receiving the bill information uploaded by the invoicing party. And encrypting the bill information through the bill symmetric key to obtain a bill ciphertext. And the block chain node encrypts the bill symmetric key through the public key of the invoicing party and the public key of the consumer to obtain a first bill symmetric key ciphertext and a second bill symmetric key ciphertext. And the block chain link point associates the bill ciphertext, the first bill symmetric key ciphertext, the second bill symmetric key ciphertext and the electronic bill billing inquiry code to generate the electronic bill. The electronic bill billing inquiry code is generated by carrying out hash operation on bill information.

In one embodiment, the consumer, upon triggering the reimbursement document via the mobile application, attaches the item symmetric key to the reimbursement document such that the recipient device can decrypt the electronic item based on the corresponding item symmetric key to obtain item information.

In one embodiment, after the recipient device finds the electronic ticket from the block link point, the electronic ticket may be sent to the terminal where the consumer is located. And the consumer decrypts the second bill symmetric key ciphertext through the consumer private key to obtain a bill symmetric key, and feeds the bill symmetric key back to the electronic bill receiver.

S404, the electronic bill is decrypted through the bill symmetric key to obtain bill information.

Specifically, the receiving device can decrypt the electronic bill through the bill symmetric key to obtain the bill information. The bill information comprises an electronic bill identification, a bill state, a billing party identification, a receiving party identification, a resource transfer share and the like.

S406, checking the reimbursement bill according to the decrypted bill information.

Specifically, the receiving party equipment checks the reimbursement document according to the decrypted bill information. In one embodiment, the ticket information includes ticket status and resource transfer related information. The receiver device can verify the bill status; and when the bill state indicates that the electronic bill is in the non-reimbursement state, checking the reimbursement bill according to the related information of the resource transfer.

Specifically, the recipient device can extract the ticket status from the ticket information, and when the electronic ticket is in the reimbursed status, the reimbursement document reconciliation is not passed. When the electronic bill is in the non-reimbursement state, the receiver equipment checks the reimbursement bill according to the related information of the resource transfer. For example, the recipient device may check whether the generation time of the electronic ticket is consistent with the reimbursement ticket, whether the category to which the resource in the electronic ticket belongs (e.g., transportation fees, lodging fees, dining fees, etc.) is consistent with the reimbursement ticket, and so on. Therefore, when the bill state indicates that the electronic bill is in the unreported state, the reimbursement bill is checked according to the resource transfer related information, repeated reimbursement of the electronic bill can be prevented, and the checking efficiency of the reimbursement bill is improved.

In the above embodiment, the electronic ticket stored in the block link point in the block chain network is data in an encrypted state, so that other people except a party related to the electronic ticket can be prevented from acquiring the plaintext information of the electronic ticket, and the security of the electronic ticket can be guaranteed. The receiver decrypts the electronic bill through the bill symmetric key corresponding to the electronic bill to obtain the bill information, and then executes the checking action, so that the electronic bill verification method is safe and convenient.

In one embodiment, as shown in fig. 5, the data processing method for electronic tickets further includes an updating step of the electronic ticket, which specifically includes the following steps:

s502, the block chain node generates an electronic bill reimbursement inquiry code corresponding to the updated bill information.

The electronic bill reimbursement inquiry code is used for inquiring the electronic bill and is uniquely corresponding to the electronic bill. The electronic bill reimbursement inquiry code can be specifically a character string, a two-dimensional code or a bar code and the like. Specifically, the block link point can perform hash operation on the updated bill information through a hash algorithm to obtain the electronic bill reimbursement inquiry code. Examples of the Hash Algorithm include MD5 (Message Digest Algorithm, fifth edition), SHA1 (Secure Hash Algorithm), SHA2, and the like, and the embodiment is not limited in this respect.

In another embodiment, the block link point may encrypt the updated ticket information using an encryption algorithm to obtain the ticket ciphertext. And generating a corresponding electronic bill reimbursement inquiry code according to the bill ciphertext. Among them, the encryption algorithm, such as symmetric encryption algorithm and asymmetric encryption algorithm, etc. A symmetric Encryption Algorithm, such as DES (Data Encryption Standard), AES (Advanced Encryption Standard), IDEA (International Data Encryption Algorithm), and the like. Asymmetric encryption algorithms, such as RSA (Rivest, shamir, adleman, encryption Algorithm), DSA (Digital Signature Algorithm), or ECC (Elliptic curve cryptography), etc.

In one embodiment, the blockchain node may perform a hash operation on the updated ticket information to obtain a hash value of the updated ticket information. Or, the block link point can also perform hash operation on the bill ciphertext to obtain a corresponding bill hash value.

In one embodiment, the blockchain node may directly use the ticket hash value as the electronic ticket reimbursement lookup code. In another embodiment, the block chain node generates the electronic ticket reimbursement inquiry code based on the ticket hash value and the signature data including the private key signature of the recipient device.

S504, the block chain node point updates the electronic bill according to the updated bill information and the electronic bill reimbursement inquiry code, and writes the updated electronic bill into the data block.

The data block is a memory module for storing data in a block link point. Specifically, after the block link point generates the electronic bill reimbursement inquiry code, the updated bill information and the electronic bill reimbursement inquiry code can be associated to generate the updated electronic bill. The block chain node may write the updated electronic ticket to the data block. The electronic bill reimbursement inquiry code can be regarded as an index of the electronic bill and is used for searching the corresponding electronic bill.

In one embodiment, before generating the electronic ticket reimbursement inquiry code, the blockchain node sends corresponding ticket information and the like to other blockchain nodes in the blockchain network, and after the blockchain nodes reach consensus, the blockchain nodes generate the electronic ticket reimbursement inquiry code. At this point, the block chain node may write the electronic ticket directly to the data block as new blocks are generated.

In one embodiment, the blockchain node may send the updated electronic ticket to other blockchain nodes in the blockchain network after updating the electronic ticket, and the blockchain nodes write the updated electronic ticket into the data block after reaching the consensus.

S506, feeding back the reimbursement inquiry code of the electronic bill by the block link points; the electronic bill reimbursement inquiry code is used for inquiring the updated electronic bill.

Specifically, the block chain node feeds back an electronic bill reimbursement inquiry code to the electronic bill public server and/or the receiver equipment corresponding to the receiver identification, wherein the electronic bill reimbursement inquiry code is used for inquiring the updated electronic bill. The updated electronic ticket is in a reimbursed state.

In one embodiment, the blockchain node feeds back the electronic ticket reimbursement inquiry code and feedback information indicating that the ticket update was successful to the electronic ticket public server and/or the recipient device. The feedback information indicating successful ticket update may specifically be a feedback code indicating successful ticket update, such as 2222 or 3333.

In one embodiment, after receiving the electronic bill reimbursement inquiry code fed back by the blockchain node, the receiver device and/or the electronic bill public server can search the corresponding electronic bill from the blockchain node in the blockchain network according to the electronic bill reimbursement inquiry code.

In one embodiment, the consumer may store the updated ticket information via the electronic ticket public server and log into the electronic ticket public server via the consumer identification to view the ticket information associated with the consumer identification.
