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 invention.
The terms "first," "second," "third," and the like in the description and in the claims, and in the above-described drawings, are used for distinguishing between different objects and not necessarily for describing a particular sequential or chronological order. Furthermore, the terms "comprises" and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or modules is not limited to the listed steps or modules but may alternatively include other steps or modules not listed or inherent to such process, method, article, or apparatus.
In order to better understand the information processing method disclosed in the embodiment of the present invention, a system architecture to which the embodiment of the present invention is applicable is first described below.
Referring to fig. 1, fig. 1 is a system architecture diagram of the present invention, which includes a client 101, an enterprise platform 102, a blockchain network 104, and a tax platform 105. Optionally, a hosting platform 103 may also be included. The form and number of the clients 101 are for example, and are not limited to the embodiment of the present invention. For example, two clients 101 may also be included. Wherein, the client can be any one of the following: a terminal, a standalone application, an Application Programming Interface (API), or a Software Development Kit (SDK). Among others, the terminal may include but is not limited to: smart phones (such as Android phones, IOS phones, and the like), tablet computers, portable personal computers, Mobile Internet Devices (MID), and the like, which are not limited in the embodiments of the present invention.
The enterprise platform 102 is a platform corresponding to an enterprise that can provide reimbursement services to the operating users 106 of the clients 101. The hosting platform 103 may be a platform authorized by the enterprise platform 102 and the tax platform 105 to bind with the enterprise platform 102, instead of the enterprise platform 102 executing and completing the reimbursement process. The enterprise platform 102 may be a server or a client of an enterprise, and the hosting platform 103 may be a server or a client of a hosting organization. Both the enterprise platform 102 and the hosted platform 103 may be operated by one or more users.
The tax platform 105 may be a platform corresponding to a tax authority, such as: a tax administration platform, a local tax platform, etc. In the present invention, the interface of the tax platform 105 may also be a node in the block chain network 104, and the node may obtain an accurate target original asset, for example: the recorded information of the invoices which are issued can also be checked for the related information of the original assets sent by the enterprise platform 102 or the hosting platform 103. The processing device corresponding to the platform can be a server or a client of the tax authority.
The Block Chain (Block Chain) is a Chain data structure which combines data blocks in a sequential connection mode according to a time sequence and is a distributed book which is cryptographically used for ensuring that the data cannot be tampered and forged. Multiple independent distributed nodes (i.e., blockchain nodes) maintain the same record. The blockchain technology realizes decentralization and becomes a foundation for credible digital asset storage, transfer and transaction. The blockchain network 104 includes a plurality of blockchain nodes. Fig. 1 illustrates an example of a blockchain network 104 including 3 blockchain nodes. Of course, the blockchain network 104 may also include more than 3 blockchain nodes. The block link points may be full nodes or other types of nodes. A full node refers to a node that stores a complete blockchain. A full node is typically a high performance computing device.
In the embodiment of the present invention, different users may use the asset transfer system in fig. 1 to complete different asset transfer methods, where block chain node 1 and block chain node 2 are used to execute the method in the embodiment of the present invention as an example:
the client 101 may request the blockchain node 1 to send the original asset to the enterprise platform 102, so that the enterprise platform 102 may extract the first asset information from the original asset and generate a summary of the first asset information, and the enterprise platform 102 may also transmit the summary of the first asset information to an interface of the tax platform 105 through the blockchain network 104, where the interface of the tax platform 105 may also be understood as any node in the blockchain network 104, such as: and if the block chain node 2 passes the verification, returning the result of passing the verification to the enterprise platform 102.
Optionally, the client 101 may further request the blockchain node 1 to send the original asset to the hosting platform 103, where the hosting platform 103 is a platform already bound to the enterprise platform 102, and specifically, authorization and binding with the enterprise platform 102 may be completed by logging in the tax platform 105, and then the hosting platform 103 may replace the enterprise platform 102 to complete docking with the client 101 and the tax platform 105, and execute the asset transfer process, and the blockchain node 2 may check the second asset information according to whether the binding relationship exists between the enterprise platform 102 and the hosting platform 103, and if the check is passed, return the result of the check to the enterprise platform 102, or optionally, return the result to the hosting platform 103, and forward the result to the enterprise platform 102 by the hosting platform 103.
It is to be understood that the asset transfer system described in the embodiment of the present invention is for more clearly illustrating the technical solution of the embodiment of the present invention, and does not constitute a limitation to the technical solution provided in the embodiment of the present invention, and as a person having ordinary skill in the art knows that along with the evolution of the system framework and the appearance of a new service scenario, the technical solution provided in the embodiment of the present invention is also applicable to similar technical problems.
Referring to fig. 2, fig. 2 is a diagram of an application scenario of an asset transfer method according to an embodiment of the present invention, where the asset transfer method may be executed by a block link point. As shown in FIG. 2, the asset transfer method may include sections 201-204. Wherein:
201. the enterprise platform 102 sends the first transaction data to the block link point 2.
Specifically, the enterprise platform 102 sends the first transaction data to the blockchain node 2, and accordingly, the blockchain node 2 receives the first transaction data from the enterprise platform 102. Wherein the first transaction data includes a summary of the first asset information generated from the original asset sent by the client 101. The original property can be understood here as an original PDF bill, which is a bill issued by the invoicing party to the operating user 106 of the client 101, wherein the operating user 106 can also be understood as a consumer. When the enterprise platform 102 acquires the PDF bill, the PDF bill may be further scanned to extract first asset information in the bill, where the first asset information may also be described as key information. The key information here may include: head-up information, invoicing party information, and the like. Scanning methods include, but are not limited to: the content of the bill is scanned and identified, or the identification (such as a two-dimensional code) of the bill is scanned, so as to automatically acquire the content of the bill. Further, the enterprise platform 102 may calculate the extracted first asset information to obtain a summary of the first asset information, so that the tax platform 105 may obtain, from the blockchain network 104, a target original asset corresponding to the summary of the first asset information according to the summary of the first asset information, where the target original asset is recorded information that has been recorded in the blockchain network 104 when the invoicing party invoices, and may also be considered as recognized real invoice information.
202. And the block chain node 2 performs consensus processing on the first transaction data according to the abstract of the first asset information, and if the consensus is passed, the first target transaction data is obtained.
Specifically, the blockchain node 2 performs consensus on the summary of the first asset information in the first transaction data in the blockchain network 104, and if the consensus is passed, obtains first target transaction data; if the consensus is not passed, the result of the execution failure is returned. The first target transaction data is the first transaction data passing the consensus. The newly added blocks of each node can be guaranteed to be identical through a consensus algorithm. A plurality of transaction records are recorded in each block, and the transaction records also comprise the hash (hash) value of the previous block, and all blocks store the hash value of the previous block in the way and are connected in sequence to form a block chain. Consensus algorithms include, but are not limited to, Proof of Work (PoW) algorithms, Proof of rights (PoS) algorithms, cleared Proof of rights (DPoS) algorithms, Practical Byzantine Fault Tolerance (PBFT) algorithms, and the like.
As an optional implementation manner, the first transaction data includes enterprise information, and when the first transaction data is subjected to consensus processing according to the abstract of the first asset information, a target original asset matched with the abstract of the first asset information may be acquired in the blockchain network 104 according to the abstract of the first asset information, that is, it is determined whether a target original asset corresponding to the abstract of the first asset information exists in the blockchain network 104, where the target original asset is a true and accurate ticket that has been recorded in the blockchain network 104 when the invoicing party makes a ticket. If the target original asset can be obtained according to the abstract of the first asset information, head-up information of the target original asset is further obtained; and if the target original asset cannot be acquired, returning a result of failed execution. The new-head information is information of reimbursement enterprises, and in the present invention, the reimbursement enterprises are information of the enterprise platform 102, such as: business name, business identification, etc. If the new line information of the target original asset matches the enterprise information of the enterprise platform 102, determining that the first transaction data passes consensus; if the head-up information of the target original asset does not match the enterprise information of the enterprise platform 102, a result of execution failure is returned.
Based on the optional implementation mode, the original bill sent by the enterprise platform 102 can be verified, whether the bill is a real block chain bill or not and whether the head-up information of the bill is the information of the enterprise platform 102 submitting the original bill or not can be verified, the authenticity of the bill is effectively ensured, and the risk of counterfeit bills is reduced.
Optionally, the first transaction data may also include a digest of the enterprise certificate of the enterprise platform 102 and a fourth public key of the enterprise platform 102, and then the enterprise certificate of the enterprise platform 102 may be obtained according to the digest of the enterprise certificate, where the enterprise certificate of the enterprise platform 102 carries the target public key, and whether the fourth public key is the same as the target public key is determined. If the enterprise certificate of the enterprise platform 102 can be obtained according to the digest of the enterprise certificate and the fourth public key is the same as the target public key, an execution failure result is returned if the enterprise certificate cannot be obtained or the fourth public key is different from the target public key according to the obtained information of the enterprise certificate of the enterprise platform 102. Under the condition that the enterprise certificate is obtained, judging whether the enterprise certificate information is matched with the head-up information or not, and if so, determining that the first transaction data passes consensus; and if not, returning an execution failure result. The method for acquiring the head-up information may refer to the above process, which is not described herein again. The enterprise certificate is generated by the certificate authority according to the fourth public key and the enterprise information sent by the enterprise platform 102.
Based on the alternative embodiment, the enterprise information of the enterprise platform 102 can be further verified, and the authenticity and accuracy of the blockchain ticket are ensured.
Optionally, the first transaction data may further include a second digital signature of the enterprise platform 102, where the second digital signature is obtained by signing the first transaction data by the operating user 107 of the enterprise platform 102, the block node 2 may verify the second digital signature, and if the second digital signature is successfully verified, it is determined that the first transaction data passes the consensus. For example: taking a hash algorithm as an example, the enterprise platform 102 performs a hash operation on the first transaction data to obtain a hash value 1. The operating user 107 of the enterprise platform 102 signs the hash value 1 with the private key of the enterprise platform 102 to obtain a second digital signature, and then sends the first transaction data and the second digital signature to the block link point 2. Correspondingly, the blockchain node 2 may decrypt the second digital signature through the public key of the enterprise platform 102 to obtain the hash value 1, and then perform hash operation on the first transaction data to obtain the hash value 2. If hash value 2 is the same as hash value 1, chunk chain node 2 verifies the first digital signature successfully. Wherein, the public key and the private key can be created by adopting an asymmetric encryption algorithm. Asymmetric encryption algorithms herein may include, but are not limited to: the Elgamal algorithm (an asymmetric encryption algorithm), the Rabin algorithm (an asymmetric encryption algorithm), the Diffie-Hellman algorithm (an asymmetric encryption algorithm), the ECC algorithm (elliptic curve encryption algorithm).
203. The blockchain node 2 generates a first asset result from the first target transaction data.
Specifically, the blockchain node 2 generates the first asset result according to the first target transaction data, where the first target transaction data includes the summary of the consensus first asset information, and the first asset result may also include the summary of the consensus first asset information, so that the enterprise platform 102 may determine that the first transaction data has passed the consensus according to the summary of the consensus first asset information, and collect the original asset corresponding to the summary of the first asset information.
As an optional implementation manner, the first asset result may further include the resource quantity, and in a case that the target original asset is obtained according to the summary of the first asset information, the resource quantity of the target original asset may be further obtained. Here, the method for obtaining the target original asset according to the abstract of the first asset information may refer to the related description in step 202, which is not described herein again. The resource quantity is the sum of the bill, namely the reimbursement sum on the bill made by the invoicing party. The resource amount may be an actual monetary amount, such as: 100 yuan, 1000 yuan, etc. In the case of obtaining the actual reimbursement amount of the ticket, the actual reimbursement amount may be sent to the enterprise platform 102, so that the enterprise platform 102 may check whether the actual reimbursement amount is consistent with the actual reimbursement amount of the ticket sent to the enterprise platform 102 by the client 101 according to the reimbursement amount.
Based on the optional implementation manner, the amount of the real blockchain bill issued by the tax platform 105 and recorded in the blockchain network 104 may be acquired, and the amount of the bill is sent to the enterprise platform 102, so that the enterprise platform 102 checks the amount of the original bill sent by the client 101 according to the real amount of the bill, thereby ensuring the accuracy of the bill and avoiding the occurrence of economic loss.
Specifically, before step 203 is executed, if the first transaction data is agreed in the blockchain network 104, the first target transaction data passing the agreement is obtained, and the uplink processing may be further performed on the summary of the first asset information passing the agreement included in the first target transaction data.
For example, as shown in fig. 3, the blockchain network 104 includes blockchain nodes 1 to blockchain nodes 3. When receiving the first transaction data, the blockchain node 2 may check the first transaction data by a certain blockchain node (e.g., a node proving the largest workload), and may check the summary of the first asset information. If the verification is passed, a first block comprising the first target transaction data is generated, the first block is identified in common, and when the identification is passed, the first block is linked.
204. Blockchain node 2 sends the first asset result to enterprise platform 102.
Specifically, block link point 2 sends a first asset result to enterprise platform 102, and correspondingly, enterprise platform 102 receives the first asset result. The first asset result may include a summary of the first asset information obtained through the consensus, and may also include the resource quantity of the target original asset, and the related description of the resource quantity of the target original asset may refer to the related description in step 203, which is not described herein again.
Optionally, before sending the first asset result to the enterprise platform 102, the tax platform 105 may sign the first asset result with a universal private key of the tax platform 105, which may be understood as a universal private key that may transfer all blockchain tickets or information related to blockchain tickets.
It can be seen that by implementing the method described in fig. 2, the enterprise platform 102 may send the first transaction data including the abstract of the first asset information to the blockchain node 2, so that the blockchain node 2 obtains the heading information of the target original asset and the target original asset corresponding to the abstract of the first asset information, that is, the heading information of the official registration accurate ticket and ticket, and if the target original asset can be obtained and the heading information is the same as the enterprise information of the enterprise platform 102, the first transaction data generates the first asset result through consensus and sends the first asset result to the enterprise platform 102, so that the enterprise platform 102 completes the flow of ticket checking and ticket collecting, and thus, the timely, accurate and safe transfer of the asset is achieved, and the reimbursement flow is simplified.
Referring to fig. 4, fig. 4 is an application scenario diagram of an asset transfer method according to an embodiment of the present invention, and as shown in fig. 4, the asset transfer method may include portions 401 to 405. Wherein:
401. the blockchain node 1 obtains a first public key of the client 101 and a second public key of the tax platform 105.
Specifically, the block chain node 1 may obtain the first public key of the client 101 and the second public key of the tax platform 105 when the client 101 applies for issuing a bill. Optionally, the first public key may also be sent to the blockchain node 1 by the client 101.
402. And the block chain node 1 performs multiple signature algorithm processing on the first public key and the second public key to generate address information.
Specifically, under the condition that the first public key and the second public key are obtained, the blockchain node 1 performs multiple signature calculation on the first public key and the second public key to obtain address information, wherein the address information is used for indicating a transaction address, and the transaction address is a multiple signature address established between the client and the tax platform and can be used for storing original assets, namely, an invoicing party can store invoicing data issued by the operating user 106 corresponding to the client 101 into the multiple signature address.
Based on the implementation mode of the steps 401 and 402, the transfer of the bill is public and transparent, the transfer process is more convenient and public, the timely, accurate and safe transfer of the assets is facilitated, and the reimbursement process is simplified.
Optionally, the blockchain node 1 may send the address information to the client 101, so that the client 101 sends the transfer data including the address information to the blockchain node 1. If the correspondence between the client 101 and the address information is recorded in the blockchain network 104, the transfer data in step 403 may also replace the address information included in the transfer data with the identifier of the client 101, so that the blockchain node 1 acquires the address information matched with the client 101 according to the identifier of the client 101.
403. The client 101 sends the transfer data to the chunk link point 1.
Specifically, the client 101 sends transfer data to the block link point 1 when receiving the original asset issued by the invoicing party, and correspondingly, the block link node 1 receives the transfer data, where the transfer data includes a first public key of the client 101, a second public key of the tax platform 105, address information, and an enterprise platform identifier. For the related description of the first public key, the second public key and the address information, refer to step 402, which is not described herein again. The enterprise platform identification may be an address of the enterprise platform 102, and the enterprise platform identification is used to send the original asset stored in the transaction address to the corresponding enterprise platform 102 according to the enterprise platform identification. The original asset may be described as an original ticket. The process of receiving the original bill issued by the invoicing party by the client 101 may be that the invoicing party sends the original bill in the PDF format to a multiple signature address between the client 101 and the tax platform 105, so that the client 101 may obtain the original bill in the PDF format, and may also forward the original bill in the PDF format to the enterprise platform 102 through the block link node 1.

Based on the implementation mode of the steps 403-405, the bills are used as assets to be transferred in the block chain, so that the problems of one bill, multiple reports and the like are avoided, and the safety of the asset transfer process is ensured.
It can be seen that by implementing the method described in fig. 4, the client 101 may forward the original ticket sent to the transaction address at the time of billing to the enterprise platform 102 as an asset, and the enterprise platform 102 may obtain the original ticket from the transaction address according to the first public key of the client 101 and the second public key of the tax bureau 105. At this time, the client 101 no longer holds the original ticket, thereby effectively avoiding the occurrence of the situations of one ticket with multiple reports and the like, ensuring the timely, accurate and safe transfer of the assets, and simplifying the reimbursement process.
For example:
the user A consumes 100 yuan at a merchant B, the merchant B issues a PDF format invoice to the address of the user A, the address is a multiple signature address between the user A and a tax bureau C, the rising head of the invoice is an enterprise D, the enterprise D is a reimbursement enterprise, the user A forwards the invoice to the enterprise D through a blockchain, the enterprise D acquires the PDF format invoice, scans the invoice to obtain key information of the invoice content, performs hash calculation to obtain an abstract of the invoice, uploads the abstract of the invoice to a blockchain port corresponding to a tax platform 105, then a node in the blockchain network 104 verifies the invoice, the recorded invoice issuing information in the tax bureau can be acquired in the blockchain network according to the abstract of the invoice, and the rising head information in the invoice issuing information recorded by the tax bureau is the same as the enterprise information of the enterprise D, the invoice passes the verification, the result that the invoice passes the verification is returned to the enterprise D, and meanwhile, the invoicing amount in the invoicing information recorded by the tax bureau can also be sent to the enterprise D, for example: the sum is 100 yuan. And after receiving the verification result, the enterprise D can judge that the invoice is a real block chain invoice, and if the amount of the invoice is consistent with that of the invoice sent by the user A, executing invoice collection and finishing the reimbursement process.

Specifically, the operation user 108 of the hosting platform 103 and the operation user 107 of the enterprise platform 102 may log in to the tax platform 105 to complete the authentication, authorization and binding processes. For example: the method can authorize legal bill hosting enterprises for the tax bureau, and then a person responsible for the reimbursement enterprise can authorize the reimbursement enterprise to bind with the reimbursement enterprise for which the reimbursement enterprise is responsible. In the case of completing the binding, the hosting platform 103 may complete the flow of reimbursement such as receipt instead of the enterprise platform 102, for example: after receiving the invoice, the employee of the reimbursement enterprise a may forward the invoice to the hosting enterprise B, or forward the invoice to the reimbursement enterprise a, and forward the invoice to the hosting enterprise B by the reimbursement enterprise a to execute subsequent reimbursement processes such as receipt and the like.
502. And the block chain node 2 performs consensus processing on the second transaction data according to the abstract of the second asset information, and if the consensus is passed, second target transaction data is obtained.
Specifically, the blockchain node 2 performs consensus on the summary of the second asset information in the second transaction data in the blockchain network 104, and if the consensus is passed, the second target transaction data is obtained; if the consensus is not passed, the result of the execution failure is returned. Here, for the description of performing consensus processing on the second transaction data, reference may be made to the description of performing consensus processing on the first transaction data in step 202, which is not described herein again.
