The structured data corresponding to the data association image can be, for example, a ticket code, an amount of the issued ticket, ticket issuing enterprise information, and the like. In order to better understand the embodiments of the present application, the following description will be given by taking the application to the field of documents as an example, unless otherwise specified.

In one embodiment, a node may receive a target data uplink request carrying user information and a data associated image, call an image recognition model to recognize the data associated image through a pre-deployed intelligent contract, and determine structured data corresponding to the data associated image based on a recognition result. Further, the consensus node in the block chain network performs consensus verification on the structured data, and after the consensus verification is passed, the structured data and the user information are written into the block chain corresponding to the block chain network in an associated manner. On one hand, the efficiency of acquiring the structured data corresponding to the data-associated image is improved by combining the image recognition technology; on the other hand, the extraction and storage of the structured data on the block chain are realized by combining the non-tamper-proof property of the block chain, so that the transparency of the whole process can be improved, the problem that the structured data is tampered is prevented, and the accuracy and the reliability of the extracted structured data are improved.
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.

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. The hash value of the previous block is stored in the block head of the next block in the block chain, and when the transaction data in the current block changes, the hash value of the block is changed, so that the transaction data uploaded to the block chain network is difficult to tamper, the transaction is carried out on the block chain, the transaction process is transparent, and the reliability of the transaction data is improved.
In order to better understand a data processing method based on a block chain disclosed in the embodiment of the present application, a block chain system applicable to the embodiment of the present application is first described below.
Referring to fig. 2, fig. 2 is a schematic diagram of an architecture of a data processing system according to an embodiment of the present disclosure. As shown in fig. 2, the data processing system comprises at least one terminal device 201, a first node 202, at least one second node 203 of a blockchain network. It should be noted that the blockchain network shown in fig. 2 is composed of one first node 202 and two second nodes 203, which is only for example and does not constitute a limitation to the embodiment of the present application. For example, in another example, a blockchain network may be comprised of one first node 202 and four second nodes 203.
In an embodiment, the first node 202 may be any one of the blockchain node devices in the blockchain network, the first node 202 may also be the blockchain node device closest to the terminal device 201, and the first node 202 may also be the blockchain node device with the best communication quality with the terminal device 201, which is not limited herein.
In one embodiment, the first nodes 202 are selected from all first nodes in the blockchain network according to a consensus algorithm, wherein the consensus algorithm includes, but is not limited to, a Proof of workload (Proof of Work, PoW) algorithm, a Proof of rights (Proof of stamp, PoS) algorithm, a granted Proof of rights (DPoS) algorithm, a Practical Byzantine Fault Tolerant (PBFT) algorithm, and the like.

Further, the consensus node in the block chain network performs consensus verification on the structured data, and after the consensus verification is passed, the structured data and the user information are written into the block chain corresponding to the block chain network in an associated manner.
It is to be understood that the data processing system described in the embodiment of the present application is for more clearly illustrating the technical solution of the embodiment of the present application, and does not constitute a limitation to the technical solution provided in the embodiment of the present application, and as a person having ordinary skill in the art knows that along with the evolution of the system architecture and the appearance of a new service scenario, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.
Referring to fig. 3, it is a flowchart illustrating a data processing method based on a blockchain according to an embodiment of the present disclosure, where the method according to the embodiment of the present disclosure may be executed by a node (e.g., a first node in fig. 2) of a blockchain network. The method of an embodiment of the present application includes the following steps.
S301: receiving a target data uplink request, wherein the target data uplink request carries user information and a data associated image. In a specific implementation, any user can send a target data uplink request to a node in a blockchain network through a terminal device of the user, where the target data uplink request carries user information of the user and an uploaded data associated image.
S302: and calling an image recognition model to recognize the data associated image through the pre-deployed intelligent contract, and determining the structured data corresponding to the data associated image based on the recognition result. The data-related image is taken as an image corresponding to the invoice as an example, and the structured data comprises information such as invoice codes, invoice amount, invoice issuing enterprise information and the like.
In one embodiment, an intelligent contract may be pre-deployed on the blockchain, the intelligent contract providing that upon receiving any one target data uplink request, an image recognition model is invoked to identify a data-associated image carried in the target data uplink request. The image recognition model is obtained by training a large number of training samples in advance, corresponding structured data can be well extracted from the data association image, and the image recognition model can be a neural network model.
In consideration of the fact that some data-related images are folded or damaged corresponding to target objects (such as bills), some field details may not be recognized on the data-related images in the process of recognizing the data-related images, so that the recognition result for the data-related images is inaccurate. According to the embodiment of the application, before the structured data corresponding to the data associated image is determined based on the identification result, whether the identification result includes the preset key information or not is detected, if the identification result includes the preset key information, it is indicated that the target object corresponding to the data associated image may not be folded or damaged, and the identification result can be directly determined as the structured data corresponding to the data associated image. The preset key information includes that configuration can be made according to business needs, the data-associated image is taken as an image corresponding to the invoice as an example, and the preset key information can be invoicing date, invoice code, invoice number, invoice amount and the like.
Or, if it is detected that the recognition result includes the preset key information, indicating that the target object corresponding to the data associated image may be folded or damaged, acquiring identification information (e.g., a ticket number) of the target object corresponding to the data associated image from the recognition result, sending a ticket data request including the identification information to a target node in the blockchain network, where the ticket data request indicates the target node to acquire object data of the target object based on the identification information, and returning the object data of the target object. Further, object data returned by the target node can be received, and structured data corresponding to the data association image can be determined based on the object data. The target node is a node associated with a service corresponding to a target object in the blockchain network, taking the target object as a bill as an example, the target node may refer to a node corresponding to a tax bureau, and the target data is bill detail data (such as a bill code, a billing amount, bill billing enterprise information, and the like). By adopting the mode, the accuracy of the obtained structured data can be improved by combining the target node.
By taking the target object corresponding to the data associated image as the invoice and the target node as the tax node as an example, in the process of determining the structured data corresponding to the data associated image, the tax node can be combined, and by identifying the number of the invoice and calling the tax interface, the detail is further inquired, and the identification accuracy is improved. The tax interface needs to be charged, so that the cost is high, the service promotion is inconvenient, and the tax interface is recommended to be called only under the condition that the invoice identification accuracy is not high.
The judging mode that the invoice identification accuracy is not high is as follows: because some bills are folded or damaged, some field details may not be identified on the invoice image in the process of identifying the invoice image. If the identification result of the invoice image is detected not to include the key information, it can be determined that the invoice identification accuracy is low. The key information may include invoicing date, invoice code, invoice number, invoice amount, and the like. The key fields can be configured according to the service requirements.
S303: and performing consensus verification on the structured data through a consensus node in the block chain network, and writing the structured data and the user information into a block chain corresponding to the block chain network in an associated manner after the consensus verification is passed.
The method for writing the structural data and the user information into the block chain corresponding to the block chain network in the associated manner comprises the following steps:
in the first mode, a new block can be generated in the block chain, and the structured data and the user information can be written in the new block.
And secondly, extracting receiver information of a target object corresponding to the data association image from the structured data, determining a target block matched with the receiver information from a plurality of blocks on the block chain, and associating and writing the structured data and the user information into the target block. Wherein, assuming that the data-associated image corresponds to the ticket a of the target object, the recipient information may be information of the recipient of the ticket a, such as a business name.
The specific implementation manner of the second mode is as follows: each receiver (e.g., each enterprise) may register its own tile in the tile chain in advance, and when the node performs the step S303 to write the structured data into the tile chain, the receiver information may be obtained from the structured data, and the receiver information may be analyzed to determine an intended receiver corresponding to the structured data. Further, the block which is registered on the block chain in advance by the target receiver is determined as a target block, and the structured data and the user information are associated and written into the target block.
Subsequently, the target receiving party can obtain all the structured data submitted to the target receiving party from the target block of the target receiving party, retrieve the data related to the target receiving party, and continue the related business processing, such as accounting financial statement or invoice reimbursement and the like. Without having to look up in all blocks of the block chain.
The specific implementation of performing consensus verification on the structured data through the consensus node in the block chain network may be that the node sends the structured data, the data associated image and the user information to other nodes in the block chain network, the other nodes may perform block chain consensus on the structured data, the data associated image and the user information, and if the structural data, the data associated image and the user information are confirmed to pass through by more than a preset number of other nodes in the block chain network, it is determined that the consensus verification on the structured data passes through. Wherein the preset number is preset by a developer based on experimental measurement and calculation data.
In the embodiment of the application, a node in a block chain network can receive a target data uplink request carrying user information and a data associated image, call an image recognition model to recognize the data associated image through a pre-deployed intelligent contract, and determine structured data corresponding to the data associated image based on a recognition result. Further, the consensus node in the block chain network performs consensus verification on the structured data, and after the consensus verification is passed, the structured data and the user information are written into the block chain corresponding to the block chain network in an associated manner. On one hand, the efficiency of acquiring the structured data corresponding to the data-associated image is improved by combining the image recognition technology; on the other hand, the extraction and storage of the structured data on the block chain are realized by combining the non-tamper-proof property of the block chain, so that the transparency of the whole process can be improved, the problem that the structured data is tampered is prevented, and the accuracy and the reliability of the extracted structured data are improved.
Referring to fig. 4, which is a schematic flow chart of a data processing method based on a blockchain according to another embodiment of the present application, where the method according to the embodiment of the present application may be executed by a node of a blockchain network, as shown in fig. 4, the method includes:
s401: receiving a target data uplink request, wherein the target data uplink request carries user information and a data associated image.
S402: and calling an image recognition model to recognize the data associated image through the pre-deployed intelligent contract, and determining the structured data corresponding to the data associated image based on the recognition result.
S403: performing consensus verification on the structured data through a consensus node in the blockchain network, and after the consensus verification is passed, writing the structured data and the user information into a blockchain corresponding to the blockchain network in an associated manner, where specific implementation manners of steps S401 to S403 may refer to relevant descriptions of steps S301 to S303 in the foregoing embodiment, which are described herein again.
S404: and receiving an association operation request of the target data, wherein the association operation request comprises operation information and processing system information of a target object corresponding to the data association image, and the processing system information is used for indicating a target processing system for processing the target object. Taking target data as invoice data as an example, assuming that data is associated with a bill A of a target object corresponding to an image, the associated operation request of the target data can indicate a bill reimbursement request, the operation information can indicate reimbursement information required for reimbursement of the bill A, and the reimbursement information comprises information such as an invoice number, an invoice issuing enterprise unified social code, an invoice receiving enterprise unified social code and the like; the processing system information indicates a reimbursement processing system (i.e., the target processing system) for reimbursement processing the ticket a, and may be, for example, a financial system of a certain enterprise.
The method proposed in the embodiments of the present application may be applied to a data processing system shown in fig. 5, where the data processing system includes at least one terminal device 201, a first node 202 of a blockchain network, at least one second node 203, and at least one processing system 204. In a specific implementation, taking an invoice reimbursement scene as an example, assuming that the data is associated with a bill a of a target object corresponding to the image, when a user wants to reimburse the bill a, the user may send a bill reimbursement request (i.e., the associated operation request) to a node in the blockchain network through the terminal device, where the bill reimbursement request includes reimbursement information of the bill a and processing system information capable of processing reimbursement of the target bill (e.g., a financial system of an enterprise corresponding to the user). Alternatively, when a user submits an reimbursement request (the reimbursement request includes reimbursement information of the ticket a and processing system information) on a target processing system to which the user belongs, and a processing person checks the reimbursement request, the ticket reimbursement request may be sent to the node in order to verify the authenticity of the ticket a or to obtain details of the ticket a.
S405: structured data and user information associated with the target object are obtained from the blockchain based on the operational information, and the target processing system is determined as indicated by the processing system information.
As can be seen from the above description, through steps S401 to S403, any user can link up the structured data of the target object (e.g., the ticket) corresponding to the user information and the data-related image of the user, that is, the block chain stores the structured data of each target object. In a specific implementation, the operation information includes an identifier of the target object, and when step S405 is executed, structured data and user information corresponding to the identifier may be searched for on the blockchain based on the identifier (e.g., a ticket number), that is, the structured data and the user information associated with the target object.
S406: and sending the structured data and the user information associated with the target object to a target processing system so that a processing person corresponding to the target processing system can check and process the target object based on the structured data and the user information associated with the target object. Taking an invoice reimbursement scene as an example, assuming that the target object is the bill a, the auditing process here may refer to reimbursement auditing for the bill a.
In one embodiment, the processing person may log in the target processing system to view the structured data and the user information associated with the target object sent by the node in step S406, perform an audit on the target object based on the structured data and the user information associated with the target object, and after the audit is passed, may send a transaction request to the node, where the transaction request includes confirmation indication information, where the confirmation indication information includes a virtual resource transfer amount, an asset account of the requesting user corresponding to the association operation request, and an asset account of a recipient of the target object.
Further, after receiving the transaction request sent by the target processing system, the node may obtain the asset account of the requesting user and the asset account of the receiving party, and transfer the virtual resource transfer amount from the asset account of the receiving party to the asset account of the requesting user, thereby implementing online related processing. By taking a bill reimbursement scene as an example, the online bill reimbursement processing can be realized through the mode.
The asset account may refer to a bank account (e.g., a bank card number), or may refer to a platform account corresponding to a service platform in the blockchain network of the requesting user or the receiving party.
Illustratively, assuming the virtual resource transfer amount is 400-tuple, the above asset accounts are the bank card numbers of the requesting user and the recipient, the bank card number of the requesting user is XXXXXXXXX02, and the bank card number of the recipient is XXXXXXXXXXXXX 03. In this case, the node may send a transfer request to the bank corresponding to the recipient's bank card requesting the bank to transfer the 400-tuple from the recipient's bank card xxxxxxxx03 to the requesting user's bank card xxxxxxxxxxxx 02.
In one embodiment, after the structured data and the user information associated with the target object are sent to the target processing system, audit confirmation information sent by the target processing system may also be received, and the audit confirmation information is used for indicating that the audit processing of the target object by the processing personnel is passed. Further, a failed flag may be added to the structured data corresponding to the target object on the blockchain. Subsequent reuse of the target object can be prevented. Taking a ticket reimbursement scenario as an example, the expired tag may be a reimbursed tag for indicating that the corresponding target object has reimbursed, thereby preventing reimbursement of the ticket. In this case, in this embodiment of the present application, it is also possible to query whether a certain ticket is marked as reimbursed on the blockchain subsequently before reimbursement is performed on the certain ticket, so as to prevent reimbursement of the ticket.
In the embodiment of the application, a node in a block chain network can receive a target data uplink request carrying user information and a data associated image, call an image recognition model to recognize the data associated image through a pre-deployed intelligent contract, and determine structured data corresponding to the data associated image based on a recognition result. Further, the consensus node in the block chain network performs consensus verification on the structured data, and after the consensus verification is passed, the structured data and the user information are written into the block chain corresponding to the block chain network in an associated manner. Further, the association operation request may be received, the structured data and the user information associated with the target object may be obtained from the blockchain based on the operation information, the target processing system may be determined according to the indication of the processing system information, and the structured data and the user information associated with the target object may be sent to the target processing system, so that a processing person corresponding to the target processing system may perform an audit process on the target object based on the structured data and the user information associated with the target object. The block chain technology can be combined to assist a processor in carrying out related processing on the target object, so that the transparency of the whole process can be improved, the problem that the structured data corresponding to the target object is tampered is solved, and the efficiency and the reliability of the related processing on the target object are improved.
The embodiment of the present application further provides a computer storage medium, in which program instructions are stored, and when the program instructions are executed, the computer storage medium is used for implementing the corresponding method described in the above embodiment.
Based on the above description of the embodiment of the data processing method based on the blockchain, an embodiment of the present application further provides a data processing apparatus based on the blockchain, where the data processing apparatus based on the blockchain may be a computer program (including program code) running in the above node.
