[0020] In order to make the person skilled in the art better understand the technical solutions in one or more embodiments of the present specification, the technical solutions in one or more embodiments of the present specification will be described clearly and completely in the following with reference to the drawings in one or more embodiments of the present specification. Obviously, the described embodiments are only part of the embodiments of the present specification, not all. Based on one or more embodiments of the present specification, all other embodiments obtained by those skilled in the art without creative labor should belong to the protection scope of the present document.

[0021] An embodiment of a data processing method based on a blockchain provided by the present specification is provided:

[0022] Referring to Figure 1 , a data processing method based on a blockchain provided by the present embodiment is shown in the flow chart, referring to Figure 2 , a data processing method based on a blockchain applied to the guarantee application scenario provided by the present embodiment is shown in the flow chart.

[0023] Referring to Figure 1 , the data processing method based on a blockchain provided by the present embodiment is applied to a blockchain node in a blockchain, and specifically includes steps S102 to S108.

[0024] Step S102, obtaining a ticket query request of a project case submitted by a server.

[0025] The data processing method based on a blockchain provided by the present embodiment introduces a blockchain for ticket query and check processing in the project case audit process. Specifically, for the ticket query request submitted by the server in the project case audit process, the blockchain node performs authentication processing on the ticket query request, and after the authentication is passed, the ticket query processing is performed in the blockchain. If the to-be-checked ticket is not queried in the blockchain, the ticket query is further performed in the ticket database. In this way, through the ticket query processing by the blockchain, the repeatability check of the to-be-checked ticket is realized, and finally the query result of the to-be-checked ticket is returned to the server as the basis for the server to conduct the project case audit. Therefore, under the condition that the authenticity and uniqueness of the ticket data are guaranteed by the "non-tamperable" feature of the blockchain, the accuracy and effectiveness of the ticket query and check processing are improved, and finally the guarantee for the project case audit is provided.

[0026] The project case described in this embodiment includes a guarantee application case in a guarantee project, such as a claim case of an insurance type insurance project and the like. In the process of making a guarantee application in the guarantee project, a user participating in the guarantee project makes a guarantee application, and a provider of the guarantee project audits the guarantee application made by the user. The process of making the guarantee application and the auditing process are in the form of a "case", so it is called a guarantee application case.

[0027] In the auditing process of the guarantee application case, the user's submitted bill or voucher for making a guarantee application often needs to be audited. For example, in the process of making an insurance claim application, the user submits the corresponding bill for making an insurance claim. In the auditing process of the claim case of the insurance project, the bill submitted by the user for making an insurance claim needs to be audited.

[0028] In specific implementation, the server creates a corresponding project case according to the case application submitted by the user, and obtains the to-be-audited bill submitted by the user for the project case, and then submits the bill query request of the generated to-be-audited bill to the blockchain node in the blockchain. After the blockchain node accessed by the server receives the submitted bill query request, the bill query request is processed from the bill query request.

[0029] Specifically, the bill query request contains the case identifier of the project case and the identifier string of the to-be-audited bill. Optionally, the identifier string is generated by encrypting the bill identifier of the to-be-audited bill and the identity identifier of the user to which the to-be-audited bill belongs by using an encryption algorithm, avoiding the transmission of the user's identity identifier in plaintext, and ensuring the user's data privacy and security, wherein the identity identifier includes the user's identity identifier recorded in the to-be-audited bill. For example, the bill ID and the user's identity ID recorded in the bill are encrypted by using the SHA256 encryption algorithm to obtain the encrypted string of the bill.

[0030] In actual application, since the case related data and bill data of the user's project case belong to the user's privacy data to some extent, in order to ensure the user's data privacy and security, the user's authorization is needed to perform the bill query and check processing in the blockchain. In an optional implementation provided in this embodiment, before the bill query processing in the blockchain, a case authorization request made by the user is responded to for case authorization processing, specifically including: receiving the case authorization request synchronized by the server; creating an authorization record of the project case to which the case identifier belongs according to the case identifier contained in the case authorization request and performing on-chain processing. Optionally, the case authorization request synchronized by the server is generated according to the authorization instruction submitted by the user for the project case.

[0031] Further, the authorization of the user to the project case in practice can also be initiated by the project provider or the project agent, and for this purpose, another optional implementation provided by the embodiment adopts the following manner for case authorization processing:

[0032] receiving the server-synchronized case authorization request; wherein the server-synchronized case authorization request is generated based on the agent authorization instruction submitted by the project provider or the project agent;

[0033] According to the case identifier contained in the case authorization request, create the authorization record of the project case to which the case identifier belongs and write it into the authorization database.

[0034] The project provider includes a guarantee institution that provides a guarantee project, and the project agent includes an agent institution that provides a guarantee project agent. In the embodiment, the blockchain includes a consortium chain, and the blockchain nodes in the blockchain include consortium chain nodes in the consortium chain. Optionally, when the blockchain is a consortium chain, the consortium chain is composed of consortium chain nodes corresponding to each guarantee institution or agent institution. It should be noted that, in the process of submitting the ticket query request to the consortium chain node in the consortium chain, the consortium chain node that submits the ticket query request is the consortium chain node corresponding to the guarantee institution to which the current project case belongs.

[0035] Step S104, performing the authentication processing of the project case based on the case identifier.

[0036] After receiving the case query request submitted by the server and containing the case identifier of the project case and the identifier string of the to-be-checked ticket, the case authentication processing is performed based on the case identifier contained in the case query request.

[0037] In specific implementation, the user authorization record of the user after the authorization processing of the project case can be stored in the blockchain or the authorization database. For these two cases, the following two authentication processing methods are provided by the embodiment:

[0038] Authentication processing method one:

[0039] Based on the case identifier, query whether there is a corresponding user authorization record in the blockchain, if yes, determine that the authentication is passed; if no, determine that the authentication is not passed;

[0040] Authentication processing method two:

[0041] Based on the case identifier, query whether there is a corresponding user authorization record in the authorization database, if yes, determine that the authentication is passed; if no, determine that the authentication is not passed.

[0042] Correspondingly, after the authentication processing of the project case is performed, if the authentication is passed, step S106 is performed; if the authentication is not passed, a prompt message that the authentication is not passed is returned to the server.

[0043] Step S106: After the authentication is passed, a ticket query is performed in the blockchain based on the identification string.

[0044] The above step completes the authentication processing of the project case and, in the case where the authentication result is that the authentication is passed, a ticket query is performed based on the identification string of the ticket to be checked included in the case query request. Specifically, in the process of the ticket query in the blockchain, since the tickets of the historical project cases are stored in the blockchain, whether there is a ticket with the same identification string as the identification string of the ticket to be checked is queried in the blockchain. If there is, it indicates that the ticket to be checked submitted by the server is likely to have been used in the historical project case. Conversely, if there is not (i.e., the query fails), a ticket query needs to be further performed in the ticket database to determine whether the ticket to be checked is used in the historical project.

[0045] In actual application, for the project provider or the project agent, an important aspect of the ticket query through the blockchain in the process of auditing the project case of the user is that the ticket data between different project providers and project agents is connected through the blockchain, so as to avoid that the user applies for a case to different project providers or project agents for the same ticket, which not only brings loss to the project provider or the project agent, but also disrupts the project guarantee system. In view of this, in an optional implementation provided by the embodiment, in the process of the ticket query in the blockchain, at least one ticket with the same identification string as the identification string of the ticket to be checked is queried in the blockchain; the at least one ticket queried is filtered according to a filtering rule to obtain a target ticket.

[0046] The filtering rule includes filtering out the tickets of the same project provider or project agent as the project provider or project agent to which the project case belongs. In addition, the tickets obtained by the query can also be filtered from the perspective of ticket content, such as filtering out the tickets with different ticket types from the ticket to be checked. Correspondingly, the filtering rule also includes filtering out the tickets with different ticket types from the ticket to be checked.

[0047] On this basis, in order to improve the sufficiency of the server's review of the project case, in an optional implementation provided by the embodiment, on the basis of querying the target ticket with the same identification string as the identification string of the to-be-reviewed ticket in the blockchain, the ticket information of the target ticket and the case information of the project case to which the target ticket belongs stored in the blockchain are read; the server is returned the query result carrying the ticket information of the target ticket and the case information of the project case to which the target ticket belongs.

[0048] Correspondingly, after receiving the query result carrying the ticket information of the target ticket and the case information of the project case to which the target ticket belongs, the server performs the review processing of the project case, specifically, according to the ticket information of the target ticket and the case information of the project case to which the target ticket belongs, it is judged whether the to-be-reviewed ticket submitted for the project case is an already used ticket; if yes, it is determined that the review of the project case fails; if no, it is determined that the review of the project case passes.

[0049] In step S108, if the query fails, the ticket database is queried based on the identification string, and the query result of the to-be-reviewed ticket is returned to the server.

[0050] In the embodiment, in order to improve the comprehensiveness of the ticket query and the applicability to various scenarios, a ticket database is introduced on the basis of the blockchain. The blockchain is used to store the historical project case tickets, but the blockchain does not store the historical project case tickets at the beginning. The historical project case tickets stored in the blockchain include the tickets uploaded to the blockchain in the process of ticket query, and the tickets uploaded to the blockchain after the synchronization of the server and the authentication processing. Therefore, the ticket database is introduced as the data source of the ticket query processing.

[0051] Optionally, the ticket database records ticket data, and the ticket data is written in the following manner:

[0052] The historical ticket data is structured, and the obtained structured ticket data is written into the ticket database;

[0053] And / or,

[0054] The image recognition technology is used to extract the historical ticket data contained in the historical ticket image; for example, the OCR (Optical Character Recognition) is used to identify the text information in the historical ticket image as ticket data;

[0055] The extracted historical ticket data is structured, and the obtained structured ticket data is written into the ticket database.

[0056] In one optional implementation of this embodiment, a bill query is performed in the bill database based on the identifier string, and the query result of the bill to be verified is returned to the server. This is specifically achieved in the following manner:

[0057] The system queries the invoice database to determine if at least one invoice exists that has the same identifier string as the invoice to be verified.

[0058] If it exists, the bill information of the at least one bill is processed on the blockchain, and a query result carrying the bill information of the at least one bill is returned to the server;

[0059] If it does not exist, return a query result to the server that the document to be verified was not found.

[0060] Accordingly, if the query result returned to the server carries the bill information of the at least one bill, then after receiving the bill information carrying the at least one bill, the server determines, based on the bill information of the at least one bill and the case information of the project case to which the at least one bill belongs, whether the bill to be reviewed submitted for the project case is a used bill; if yes, it determines that the review of the project case has not passed; if no, it determines that the review of the project case has passed.

[0061] If the query result returned to the server is that the invoice to be verified was not found, the server will perform the review process for the project case after receiving the query result that the invoice to be verified was not found. Specifically, this includes determining that the project case has been approved based on the query result that the invoice to be verified was not found.

[0062] As mentioned above, the bill data stored in the blockchain comes partly from the bill query process and partly from the server synchronization and authentication process. In one optional implementation of this embodiment, the bills synchronized by the server and uploaded to the blockchain after authentication are processed are processed on the blockchain in the following way:

[0063] The server retrieves case information of historical project cases and invoice information of historical invoices synchronized by the server. The server synchronizes the case information of historical project cases and invoice information of historical invoices after recording them into the historical database.

[0064] Based on the case identifier contained in the case information, query the blockchain to see if there is a corresponding user authorization record; if so, process the case information of the historical project case and the ticket information of the historical ticket on the blockchain; if not, no processing is required.

[0065] The following is a blockchain-based data processing method provided in this embodiment, which is applied to the application of the guarantee application scenario. For further description of the blockchain-based data processing method provided in this embodiment, see Figure 2 The blockchain-based data processing method applied to the guarantee application scenario specifically includes steps S202 to S218.

[0066] Step S202 receives a case authorization request generated by a server synchronization based on an authorization instruction submitted by a user for a guarantee application case.

[0067] Step S204 creates an authorization record of the guarantee application case to which the case identifier belongs according to the case identifier contained in the case authorization request and performs a chain processing.

[0068] Step S206 obtains a ticket query request of the guarantee application case submitted by the server.

[0069] The ticket query request contains the case identifier of the guarantee application case and the identification string of the ticket to be checked.

[0070] Step S208 queries whether there is a corresponding user authorization record in the blockchain based on the case identifier contained in the ticket query request.

[0071] If yes, it is determined that the authentication is passed, and step S210 is executed.

[0072] If not, it is determined that the authentication is not passed, and a reminder message of the authentication failure is returned to the server.

[0073] Step S210 queries whether there is at least one ticket with the same identification string as the identification string of the ticket to be checked in the blockchain.

[0074] If yes, steps S212 to S214 are executed.

[0075] If not, steps 216 to S218 are executed.

[0076] Step S212 filters the at least one ticket obtained by querying according to a filtering rule to obtain a target ticket.

[0077] Step S214 reads the ticket information of the target ticket stored in the blockchain and the case information of the guarantee application case to which the target ticket belongs and returns them to the server.

[0078] Step S216 queries whether there is at least one ticket with the same identification string as the identification string of the ticket to be checked in the ticket database.

[0079] If yes, step S218 is executed.

[0080] If not, return a query result of no queried ticket to be audited to the server.

[0081] In step S218, the ticket information of the at least one ticket queried is processed for chaining, and a query result carrying the ticket information of the at least one ticket is returned to the server.

[0082] Another embodiment of the blockchain-based data processing method provided in the specification is as follows:

[0083] In the above embodiment, a blockchain-based data processing method applied to a blockchain node is provided, and in cooperation therewith, the present embodiment also provides a blockchain-based data processing method applied to a server accessing the blockchain node, which will be described below with reference to the accompanying drawings.

[0084] Referring to Figure 3 , a flowchart of a blockchain-based data processing method provided in the present embodiment is shown, referring to Figure 4 , a flowchart of a blockchain-based data processing method applied to a guarantee application scenario provided in the present embodiment is shown.

[0085] Referring to Figure 3 , the present embodiment provides a blockchain-based data processing method applied to a server accessing a blockchain node, which specifically includes steps S302 to S306.

[0086] In step S302, a ticket to be audited submitted for a project case created according to a case application is acquired.

[0087] The project case described in the present embodiment includes a guarantee application case in a guarantee project, such as a claim case of an insurance project of an insurance type, etc. In the process of guarantee application in a guarantee project, a user participating in the guarantee project proposes a guarantee application, and a provider of the guarantee project audits the guarantee application proposed by the user. The process of proposing and auditing the guarantee application is in the form of a “case”, so it is called a guarantee application case. In the auditing process of the guarantee application case, the ticket or certificate submitted by the user for the guarantee application often needs to be audited. For example, in the process of proposing an insurance claim application, the user submits the corresponding ticket for the insurance claim application, and in the auditing process of the claim case of the insurance project, the ticket submitted by the user for the insurance claim needs to be audited.

[0088] In actual application, since the case-related data and the bill data of the project case of the user belong to the privacy data of the user to some extent, in order to ensure the data privacy and security of the user, the user needs to be authorized before the bill checking process is performed on the blockchain. In an optional implementation provided by the embodiment, a case authorization request is generated according to the authorization instruction submitted by the user for the project case, and the case authorization request is synchronized to the blockchain node, so that the blockchain node performs case authorization processing according to the case authorization request.

[0089] In addition, the authorization of the user to the project case can also be initiated by the project provider or the project agent. For this purpose, in another optional implementation provided by the embodiment, a case authorization request is generated according to the authorization instruction submitted by the project provider or the project agent for the project case, and the case authorization request is synchronized to the blockchain node, so that the blockchain node performs case authorization processing according to the case authorization request.

[0090] The project provider includes a guarantee institution providing a guarantee project, and the project agent includes an agency institution providing a guarantee project agency. In the embodiment, the blockchain includes a consortium chain, and the blockchain node in the blockchain includes a consortium chain node in the consortium chain. Optionally, when the blockchain is a consortium chain, the consortium chain is composed of the consortium chain nodes corresponding to the guarantee institutions or the agency institutions. It should be noted that, in the process of submitting the bill checking request to the consortium chain node in the consortium chain, the consortium chain node submitting the bill checking request is the consortium chain node corresponding to the guarantee institution to which the current project case belongs.

[0091] In step S304, the bill checking request of the project case is generated and submitted to the blockchain node.

[0092] In the execution process, the server creates a corresponding project case according to the case application submitted by the user. After the user submits the to-be-checked bill for the project case, the server submits the bill checking request of the to-be-checked bill to the blockchain node in the blockchain. After the blockchain node accessed by the server receives the submitted bill checking request, the bill checking process is performed from the bill checking request.

[0093] Specifically, the ticket query request includes a case identifier of the project case and an identification string of the ticket to be checked. Optionally, the identification string is generated by encrypting a ticket identifier of the ticket to be checked and an identity identifier of a user to which the ticket to be checked belongs by using an encryption algorithm, so as to avoid the identity identifier being transmitted in plaintext and ensure the data privacy and security of the user, where the identity identifier includes a user identity identifier recorded in the ticket to be checked. For example, the SHA256 encryption algorithm is used to encrypt the ticket ID and the user identity ID recorded in the ticket, to obtain an encrypted string of the ticket.

[0094] In a specific implementation, after the ticket query request of the project case is submitted to the blockchain node, the blockchain node performs authentication processing on the project case based on the case identifier, and performs ticket query in the blockchain based on the identification string after the authentication is passed. If the query fails, ticket query is performed in the ticket database based on the identification string, and the query result of the ticket to be checked is returned. If the authentication processing of the project case by the blockchain node fails, a prompt message that the authentication fails is returned, and the prompt message that the authentication fails returned by the blockchain node is received.

[0095] In a specific implementation, after the ticket query request of the project case is submitted to the blockchain node, the blockchain node performs authentication processing on the project case based on the case identifier, and performs ticket query in the blockchain based on the identification string after the authentication is passed. If the query fails, ticket query is performed in the ticket database based on the identification string, and the query result of the ticket to be checked is returned. If the authentication processing of the project case by the blockchain node fails, a prompt message that the authentication fails is returned, and the prompt message that the authentication fails returned by the blockchain node is received.

[0096] In a specific implementation, after the ticket query request of the project case is submitted to the blockchain node, the blockchain node performs authentication processing on the project case based on the case identifier, and performs ticket query in the blockchain based on the identification string after the authentication is passed. If the query fails, ticket query is performed in the ticket database based on the identification string, and the query result of the ticket to be checked is returned. If the authentication processing of the project case by the blockchain node fails, a prompt message that the authentication fails is returned, and the prompt message that the authentication fails returned by the blockchain node is received.

[0097] If the query result of the ticket to be checked returned by the blockchain node carries ticket information of a target ticket and case information of a project case to which the target ticket belongs, it indicates that the blockchain node queries the target ticket identical to the ticket to be checked. Optionally, according to the query result of the ticket to be checked returned by the blockchain node, the audit processing of the project case is performed, specifically including: determining whether the ticket to be checked submitted for the project case is an already used ticket according to the ticket information of the target ticket and the case information of the project case to which the target ticket belongs; if yes, determining that the audit of the project case fails; if no, determining that the audit of the project case passes.

[0098] Further, if the query result of the to-be-checked bill returned by the blockchain node is a query result of not finding the to-be-checked bill, and optionally, according to the query result of the to-be-checked bill returned by the blockchain node, the auditing process of the project case is performed, and specifically, according to the query result of not finding the to-be-checked bill, it is determined that the project case passes the auditing.

[0099] In this embodiment, in order to improve the comprehensiveness of bill query and the applicability to various scenarios, a bill database is introduced on the basis of the blockchain. The blockchain is used to store historical project case bills, but the blockchain does not store historical project case bills at the beginning. The historical project case bills stored in the blockchain include bills uploaded to the blockchain in the process of bill query, and bills uploaded to the blockchain after the synchronization of the server and the authentication process. Therefore, the bill database is introduced as a data source for bill query processing.

[0100] In an optional implementation of the data processing method provided in this embodiment, the following method is used to synchronize bills to the blockchain: the case information of the historical project case and the bill information of the historical bill are recorded to a historical database, and the case information of the historical project case and the bill information of the historical bill are synchronized to the blockchain node. Correspondingly, after receiving the synchronized case information of the historical project case and the bill information of the historical bill, the blockchain node queries whether there is a corresponding user authorization record in the blockchain according to the case identifier contained in the case information; if yes, the case information of the historical project case and the bill information of the historical bill are processed for chain; if no, no processing is performed.

[0101] The data processing method based on the blockchain provided in this embodiment is further described below by taking the application of the data processing method based on the blockchain in the guarantee application scenario as an example. Referring to Figure 4 , the data processing method based on the blockchain applied in the guarantee application scenario specifically includes steps S402 to S414.

[0159] The above described embodiments of the present description have been described. Other embodiments are within the scope of the following claims. In some cases, the actions or steps recited in the claims can be performed in a different order and still achieve desirable results. Additionally, the processes depicted in the figures do not necessarily require the particular order shown, or sequential order, to achieve the desired results. In certain implementations, multitasking and parallel processing can be advantageous.

[0160] In the 1930s, it was clear to distinguish whether an improvement in a technology was in hardware (e.g., improvement in circuit structure of diodes, transistors, switches, etc.) or in software (e.g., improvement in method flow). However, as technology has evolved, many improvements in method flow today can be considered as direct improvements in hardware circuit structure. Designers almost always obtain the corresponding hardware circuit structure by programming the improved method flow into the hardware circuit. Therefore, it cannot be said that an improvement in a method flow cannot be implemented by a hardware entity module. For example, a programmable logic device (PLD) (e.g., a field programmable gate array (FPGA)) is an integrated circuit whose logic function is determined by user programming of the device. A digital system is "integrated" on a PLD by the designer programming it, rather than by asking a chip manufacturer to design and fabricate a custom integrated circuit chip. Moreover, instead of manually fabricating an integrated circuit chip, this programming is now mostly implemented by "logic compiler" software, which is similar to software compilers used in program development, and the original code to be compiled is written in a specific programming language, called a hardware description language (HDL), of which there are many, such as ABEL (Advanced Boolean Expression Language), AHDL (Altera Hardware Description Language), Confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), Lava, Lola, MyHDL, PALASM, RHDL (Ruby Hardware Description Language), etc., the most commonly used being VHDL (Very-High-Speed Integrated Circuit Hardware Description Language) and Verilog. It should be clear to those skilled in the art that, by simply logically programming a method flow in one of the above hardware description languages and programming it into an integrated circuit, a hardware circuit implementing the logical method flow can be easily obtained.

[0161] The controller can be implemented in any suitable way, e.g. the controller can take the form of a microprocessor or processor and a computer readable medium storing computer readable program code, e.g. software or firmware, executable by the (micro)processor, logic gates, switches, an application specific integrated circuit (ASIC), a programmable logic controller and an embedded microcontroller, examples of controllers include but are not limited to the following microcontrollers: ARC 625D, Atmel AT91 SAM, Microchip PIC18F26K20 and Silicone Labs C8051F320, the memory controller can also be implemented as part of the control logic of the memory. Those skilled in the art will also know that in addition to being implemented in pure computer readable program code form, the controller can perfectly well be implemented by means of logic programmed into logic gates, switches, application specific integrated circuits, programmable logic controllers and embedded microcontrollers, etc. to perform the same functions. The controller can thus be considered a hardware component, and the means comprised therein for performing various functions can be considered structures within the hardware component. Alternatively, or even additionally, the means for performing various functions can be considered both software modules implementing the method and structures within the hardware component.

[0162] The systems, apparatuses, modules or units illustrated by the above embodiments can be implemented by computer chips or entities, or products with certain functions. A typical implementation device is a computer. Specifically, the computer can be a personal computer, a laptop computer, a cellular phone, a camera phone, a smart phone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or a combination of any of these devices.
