[0083] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0084] See also Figure 1a , is a schematic diagram of the structure of a blockchain node system provided in an embodiment of the present application. Figure 1a As shown, the blockchain node system refers to a system for sharing data between nodes. The blockchain node system may include multiple nodes. Figure 1a As shown, the blockchain node system may specifically include node 1000a, node 1000b, node 1000c, ..., node 1000n.

[0085] Among them, in the blockchain node system, each node can obtain the associated business data information associated with the target evaluation value when performing normal work to maintain the shared data in the blockchain node system. In order to ensure the information intercommunication in the blockchain node system, a network connection can be established between each node in the blockchain node system to transmit data through the network connection. For example, when any node in the blockchain node system obtains the associated business data information, other nodes in the blockchain node system can obtain the associated business data information according to the consensus algorithm, and store the associated business data information as data in the shared data, so that the data stored on all nodes in the blockchain node system are consistent.

[0086] Each node in the blockchain node system has a node identifier corresponding to it, and each node in the blockchain node system can store other node identifiers that have a network connection relationship with the current node, so that the generated blocks can be broadcast to other nodes in the blockchain node system according to the node identifiers of other nodes. A node identifier list as shown in the following table can be maintained in each node, and the node name and node identifier are stored in the node identifier list accordingly. Among them, the node identifier can be an IP (Internet Protocol, a protocol for interconnection between networks) address and any other information that can be used to identify the node. Table 1 only uses the IP address as an example for illustration.

[0089] It should be understood that the embodiments of the present application can be Figure 1a A node is selected from the multiple nodes in the blockchain node system shown as a contract node in the blockchain network corresponding to the blockchain node system. For example, the embodiment of the present application can use the node 1000a in the blockchain node system as a contract node in the blockchain network to illustrate the process in which the node 1000a can determine the target evaluation value of the first assessment file through a smart contract and write the associated business data information associated with the target evaluation value into the blockchain corresponding to the blockchain network.

[0090] For further understanding, please refer to Figure 1b , is a schematic diagram of a network architecture provided by an embodiment of the present application. Figure 1b As shown, the network architecture may include a node 1000a, a scanning terminal 2000, a reading terminal cluster and a review terminal 4000. It is understood that Figure 1b The node 1000a shown may be the above Figure 1a Node 1000a in the blockchain node system shown may be a contract node in the blockchain network corresponding to the blockchain node system. Figure 1b The reading terminal cluster shown may include multiple reading terminals. Figure 1b As shown, the reading terminal cluster may specifically include: a reading terminal 3000a, a reading terminal 3000b, ..., a reading terminal 3000n.

[0091] Among them, Figure 1bEach reading terminal and review terminal 4000 in the reading terminal cluster shown may include: a smart phone, a tablet computer, a desktop computer, and other intelligent terminals with business data processing functions. It is understandable that each reading terminal in the reading terminal cluster of the embodiment of the present application can evaluate the business data associated with the electronic assessment file scanned by the scanning terminal 2000.

[0092] like Figure 1b As shown, the scanning terminal 2000 can be connected to the node 1000a through a network connection, so that the scanning terminal can exchange data with the node 1000a through the network connection. In addition, the reading terminal 3000a, the reading terminal 3000b, ..., the reading terminal 3000n can be connected to the node 1000a through a network connection, so that each reading terminal can exchange data with the node 1000a through the network connection. The review terminal 4000 can also be connected to the node 1000a through a network connection, so that the review terminal can exchange data with the node 1000a through the network connection.

[0093] It should be understood that the scanning terminal 2000 can scan the target test paper into an electronic assessment file and send the electronic assessment file to the node 1000a. Among them, the target test paper can be the test paper for the college entrance examination, self-examination, adult college entrance examination, high school entrance examination and other various social examinations (computer grade examination, postgraduate examination, etc.). At this time, the node 1000a can obtain the cutting identifier of the electronic assessment file, and cut the electronic assessment file into at least one area based on the cutting identifier. Among them, the cutting identifier is the mark of the node 1000a cutting the electronic assessment file. It can be understood that each area cut out by the electronic assessment file corresponds to multiple terminals, and one area corresponds to one business data.

[0094] Furthermore, the node 1000a may select an area from at least one area in the electronic assessment file, and send the business data in the area to multiple terminals associated with the area. At this time, the node 1000a may determine the multiple terminals associated with the area as reading terminals, and refer to the area received by the reading terminal as a to-be-processed area. It is understandable that, if Figure 1bThe multiple reading terminals in the reading terminal cluster shown can be multiple terminals associated with the pending area (e.g., area A) of the electronic examination document. For example, the business data in the pending area can be the business data in the area where the fill-in-the-blank questions of a certain biology test paper are located. It should be understood that each reading terminal in the reading terminal cluster can sequentially display the business data in the area where the fill-in-the-blank questions of each biology test paper sent by the node 1000a are located, and cannot display the business data corresponding to other areas of the biology test paper (e.g., area B, short answer questions). In addition, the respondent information corresponding to the target test paper cannot be displayed on each reading terminal, thereby reducing the evaluation error of the business data in the pending area caused by the subjective factors of the user corresponding to the reading terminal.

[0095] It should be understood that the user corresponding to each reading terminal in the reading terminal cluster can evaluate the business data of the area to be processed (area A), so that the evaluated evaluation value can be input into the corresponding reading terminal, so that the reading terminal sends the evaluation value to the node 1000a. Among them, it can be understood that the electronic assessment file corresponding to the area to be processed that each reading terminal is reading at this moment is called the first assessment file in the embodiment of the present application. After the reading terminal determines the business data in the area to be processed of the first assessment file, the evaluation value can be continued to be determined for at least one electronic assessment file sent by the node 1000a. Among them, each of the at least one electronic assessment file has the same area to be processed as the first assessment file. At this time, the embodiment of the present application can collectively refer to at least one electronic assessment file having the same area to be processed as the first assessment file as the second assessment file.

[0096] It is understandable that the node 1000a can obtain Figure 1b The evaluation value determined by each reading terminal in the reading terminal cluster for the business data in the to-be-processed area is shown. In this embodiment of the application, the evaluation value determined by multiple reading terminals for the business data in the to-be-processed area of ​​the first assessment file may be referred to as the first evaluation value.

[0097] Furthermore, the node 1000a can determine the abnormal evaluation value from the first evaluation value by calling the smart contract, and refer to the first evaluation value excluding the abnormal evaluation value as the evaluation value to be processed. At this time, the node 1000a can send the business data in the area to be processed to Figure 1bThe audit terminal 4000 shown. It can be understood that the business data received by the audit terminal 4000 and the business data received by each reading terminal in the reading terminal cluster are business data in the same area to be processed sent by the node 1000a. The user (auditor) corresponding to the audit terminal 4000 can evaluate the business data in the area to be processed and input the evaluation value into the audit terminal 4000 so that the audit terminal 4000 can send the evaluation value to the node 1000a. Among them, the embodiment of the present application can refer to the evaluation value determined by the audit terminal 4000 for the business data in the area to be processed of the first assessment file as the second evaluation value.

[0098] The node 1000a determines the target evaluation value corresponding to the business data in the to-be-processed area according to the second evaluation value and the to-be-processed evaluation value, and writes the associated business data information associated with the target evaluation value into the Figure 1a In the blockchain corresponding to the blockchain network shown, the reliability of the target evaluation value can be improved. The target evaluation value refers to the evaluation value finally obtained by the business data in the area to be processed.

[0099] Optional, if Figure 1b In the first evaluation values ​​determined by the multiple reading terminals in the reading terminal cluster for the business data in the above-mentioned processing area, no abnormal evaluation value appears, then the node 1000a can perform mean processing on the first evaluation value to obtain the average value of the first evaluation value. It can be understood that the node 1000a can determine the average value as the target evaluation value corresponding to the business data in the processing area, and write the associated business data information associated with the target evaluation value into the following table: Figure 1a In the blockchain of the blockchain network shown. If the determined average value is a non-integer, the node 1000a can approximate the average value (for example, round it off) and use the approximate average value as the target evaluation value of the business data in the area to be processed.

[0100] For further understanding, please refer to Figure 2 , is a schematic diagram of a scenario for data interaction provided by an embodiment of the present application. Figure 2 As shown, the contract node can be the above Figure 1b The corresponding node 1000a may be the above-mentioned node 1000a. Figure 1a The node in the blockchain node system shown. The audit terminal can be the above Figure 1b The corresponding audit terminal 4000. The reading terminal A, the reading terminal B and the reading terminal C in the reading terminal cluster are respectively Figure 1bAny reading terminal in the reading terminal cluster shown, wherein each reading terminal in the reading terminal cluster is a reading terminal associated with the area to be processed.

[0101] Among them, the embodiment of the present application only takes three reading terminals as an example, namely, reading terminal A, reading terminal B and reading terminal C. Among them, it can be understood that the business data in the to-be-processed area of ​​the first assessment file in the embodiment of the present application can be the answers filled in by candidate A to the short-answer questions of the history test paper. In other words, the electronic assessment file of the history test paper of candidate A scanned by the scanning terminal can be called the first assessment file, and the area where the short-answer questions are located can be called the to-be-processed area.

[0102] like Figure 2 As shown, the contract node can obtain the area to be processed of the first assessment file scanned by the scanning terminal that has a network connection relationship with the contract node (i.e., the area where the short-answer questions of the history test paper of candidate A are located), and distribute the area to be processed to each reading terminal in the reading terminal cluster associated with the area to be processed. It should be understood that each reading terminal in the reading terminal cluster can determine a first evaluation value for the business data in the area to be processed. For example, the first evaluation value determined by the reading terminal A for the business data in the area to be processed can be K1 (for example, 20 points), the first evaluation value determined by the reading terminal B for the business data in the area to be processed can be K2 (for example, 25 points), and the first evaluation value determined by the reading terminal C for the business data in the area to be processed can be K3 (for example, 18 points).

[0103] Further, the three reading terminals can send their respective determined first evaluation values ​​to the contract node. At this time, the contract node can perform mean processing on the received first evaluation value through the smart contract in the contract node, so as to obtain the average value between the first evaluation values ​​(i.e., 21 points). Among them, the embodiment of the present application can refer to the average value obtained after the first evaluation value determined by multiple reading terminals is processed as the first average value. It should be understood that the contract node can determine the difference between each evaluation value in the first evaluation values ​​determined by the three reading terminals and the first average value. Among them, the difference between the first evaluation value (20 points) determined by the reading terminal A and the first average value is 1 point, the difference between the first evaluation value (25 points) determined by the reading terminal B and the first average value is 4 points, and the difference between the first evaluation value (18 points) determined by the reading terminal C and the first average value is 3 points.

[0104] It should be understood that the embodiment of the present application can pre-set an abnormal threshold (for example, 3 points), and the abnormal threshold is used to determine the abnormal evaluation value between the first evaluation values ​​determined by multiple reading terminals. It is understandable that the contract node can determine the first evaluation value whose difference is greater than the abnormal threshold as the abnormal evaluation value. Therefore, the contract node can determine the first evaluation value (25 points) determined by the reading terminal B as the abnormal evaluation value. Further, the contract node can exclude the abnormal evaluation value from the above-mentioned first evaluation value, and determine the first evaluation value excluding the abnormal evaluation value as the evaluation value to be processed. The evaluation value to be processed is the first evaluation value (20 points) determined by the reading terminal A and the first evaluation value (18 points) determined by the reading terminal C.

[0105] At this time, the contract node can send the business data in the to-be-processed area of ​​the first assessment file (i.e., the answers filled in by candidate A in the area where the short-answer questions of the history test paper are located) to the Figure 2 The review terminal shown is used to enable the auditor corresponding to the review terminal to evaluate the business data in the pending area. The review terminal can send the evaluation value determined by the auditor to the contract node. Among them, the embodiment of the present application can refer to the evaluation value determined by the review terminal for the business data in the pending area of ​​the first assessment file as the second evaluation value.

[0106] Further, the contract node can obtain the first evaluation value with the maximum evaluation value and the first evaluation value with the minimum evaluation value from the above-mentioned evaluation values ​​to be processed, and the range formed by the first evaluation value with the maximum evaluation value and the first evaluation value with the minimum evaluation value is called the evaluation range. Among them, the contract node can determine from the above-mentioned evaluation values ​​to be processed that the first evaluation value with the maximum evaluation value is 20 points, and the first evaluation value with the minimum evaluation value is 18 points, so the evaluation range can be between 18 points and 20 points. In other words, the evaluation range includes 18 points, 19 points, and 20 points.

[0107] like Figure 2 If the second evaluation value (for example, 19 points) determined by the review terminal shown falls within the evaluation range, the contract node can perform mean processing on the second evaluation value and the evaluation value to be processed, so as to obtain the average value between the second evaluation value and the evaluation value to be processed (i.e., 19 points). Among them, in the embodiment of the present application, the average value obtained after the mean processing of the second evaluation value and the evaluation value to be processed can be referred to as the second average value. At this time, the contract node can use the second average value as the target evaluation value corresponding to the business data in the area to be processed. In other words, the contract node can determine that the answer filled in for the short-answer question in the history test paper of candidate A is 19 points.

[0108] Furthermore, the contract node can obtain the reading time of the business data in the pending area by each reading terminal in the reading terminal cluster, and determine the associated business data information associated with the target evaluation value according to the reading time, the abnormal evaluation value, the pending evaluation value, the second evaluation value, and the target evaluation value. The associated business data information is used to record the determination process of the target evaluation value of the business data in the pending area of ​​the first assessment file. The contract node can upload the associated business data information to the chain, thereby improving the reliability of the associated business data information.

[0109] in, Figure 2 The blockchain 1 shown can be the above Figure 1a The blockchain corresponding to the blockchain network in the contract node, the blockchain 1 can be an identical blockchain shared by each node in the blockchain network corresponding to the contract node, and each node can obtain the information stored in the blockchain in the blockchain 1. The blockchain 1 includes blocks 10a, 10b, ..., 10n and a target block, and the block 10a can be called the genesis block of the blockchain 1. The target block in the blockchain 1 contains the above-mentioned associated business data information.

[0110] Among them, the contract node can write the associated business data information into the blockchain in the blockchain network corresponding to the contract node. In other words, the contract node can obtain the block 10n with the maximum generation timestamp from the blockchain 1. Further, the contract node can generate a target block to be written into the blockchain 1 based on the associated business data information. At this time, the contract node broadcasts the target block containing the associated business data information to all blockchain nodes in the blockchain network (for example, consensus nodes used for consensus processing). When it is determined that all blockchain nodes have reached a consensus, the target block can be written into the above-mentioned blockchain 1, that is, the target block is used as the next block of block 10n.

[0111] The contract node in the blockchain network determines the target evaluation value of the business data in the area to be processed through the smart contract in the contract node, and writes the associated business data information associated with the target evaluation value into the blockchain. The specific implementation method can be seen below Figure 3-Figure 6 The corresponding embodiment.

[0112] For further information, see Figure 3 , is a flow chart of a data processing method provided in an embodiment of the present application. The method can be applied to contract nodes in a blockchain network. Figure 3 As shown, the method may include:

[0113] S101, obtaining first evaluation values ​​determined for business data in a to-be-processed area and sent by a plurality of viewing terminals.

[0114] Specifically, the contract node in the blockchain network can send the pending area of ​​the first electronic assessment file to multiple reading terminals associated with the pending area. Further, each of the multiple reading terminals can determine a first evaluation value for the business data in the pending area, and send the first evaluation value to the contract node. The pending area is the area in the first assessment file output by each reading terminal. The first assessment file refers to the electronic assessment file corresponding to the pending area that each reading terminal is reading at this moment.

[0115] It should be understood that the first electronic assessment file may be an electronic file sent to the contract node through the answering terminal where the examinee is located. The answering terminal refers to the terminal used by the examinee to answer the target test paper. For example, the first assessment file may be an electronic file of the answers given by examinee A on the answering terminal A for the computer-based test A (computer grade test).

[0116] Optionally, the first electronic assessment file can be a file obtained by the contract node from a scanning terminal having a network connection relationship with the contract node. It is understandable that the contract node can obtain the first assessment file for the target test paper sent by the scanning terminal and the cutting identifier of the first assessment file, and can cut the first assessment file into at least one area based on the cutting identifier. Among them, the target test paper can be the test paper of the college entrance examination, self-examination, adult college entrance examination, high school entrance examination and other various social examinations (graduate entrance examination, etc.). The contract node can obtain the area to be processed from the at least one area, and distribute the business data in the area to be processed to multiple terminals associated with the area to be processed. Further, the contract node can determine the multiple terminals associated with the area to be processed as reading terminals respectively, and receive the first evaluation values ​​determined for the business data in the area to be processed respectively sent by the multiple reading terminals. Among them, each area in the at least one area corresponds to multiple terminals respectively; one area corresponds to one business data. Among them, the first assessment file can also be obtained by other means, which is not limited here.

[0117] Among them, the contract node can be Figure 2 The corresponding contract node can be the above Figure 1b The node 1000a in the Figure 1a The contract node in the blockchain node system. The reading terminal can be Figure 1b Any reading terminal in the corresponding reading terminal cluster. The scanning terminal can be the above Figure 1bThe corresponding scanning terminal 2000.

[0118] It should be understood that the scanning terminal having a network connection relationship with the contract node can scan the target test papers of multiple candidates participating in the assessment into an electronic assessment file. It is understandable that the electronic assessment file carries a cutting identifier. Among them, the cutting identifier is a mark of the contract node cutting the electronic assessment file.

[0119] For further understanding, please refer to Figure 4 , is a schematic diagram of an electronic assessment file provided in an embodiment of the present application. Figure 4 As shown, the electronic examination file 100a may be an electronic scanned file obtained after the scanning terminal scans the target examination paper. The electronic examination file may be the answer sheet of subject A filled in by a candidate in the XX National College Entrance Examination. Figure 4 The content of the title 30 shown may be "2019 National College Entrance Examination Chinese Language Answer Sheet"

[0120] It should be understood that Figure 4 The identifier 20 shown is the location identifier used by the contract node to locate the electronic assessment file, and the identifier 10 is the cutting identifier used by the contract node to cut the electronic assessment file. It can be understood that the contract node can obtain the identifier 20 and locate the electronic assessment file through the identifier 20. Further, the contract node can obtain the identifier 10 in the electronic scan file and divide the electronic assessment file into at least one area based on the identifier 10. Figure 4 As shown, the contract node can divide the electronic assessment file 100a into five areas, namely area A, area B, area C, area D and area E.

[0121] Each of the five areas corresponds to multiple terminals, and each area corresponds to a business data. For example, area A corresponds to the area where multiple-choice questions are located, area B corresponds to the area where classical Chinese reading is located, area C corresponds to the area where ancient poetry appreciation is located, area D corresponds to the area where modern Chinese reading is located, and area E corresponds to the area where composition is located.

[0122] Furthermore, the contract node may obtain a to-be-processed area (e.g., area B) from the five areas, and send the business data in area B to multiple terminals associated with area B. At this time, the contract node may determine the multiple terminals associated with area B as reading terminals. The reading terminals may be the above-mentioned Figure 2 The corresponding reading terminals in the reading terminal cluster are reading terminal A, reading terminal B and reading terminal C.

[0123] It should be understood that the user corresponding to each reading terminal in the reading terminal cluster can evaluate the business data (classical Chinese reading) of the area B, and input the evaluated evaluation value into the corresponding reading terminal. Among them, the input method may include voice input, keyboard input, gesture input, etc. At this time, each reading terminal can send the evaluation value determined by the reading terminal to the contract node. Among them, the embodiment of the present application can refer to the evaluation value determined by the three reading terminals for the business data in area B as the first evaluation value. For example, the first evaluation value determined by the reading terminal A for the business data in the area B can be K1 (for example, 9 points), the first evaluation value determined by the reading terminal B for the business data in the area B can be K2 (for example, 8 points), and the first evaluation value determined by the reading terminal C for the business data in the area B can be K3 (for example, 4 points).

[0124] S102, determining an abnormal evaluation value from the first evaluation value through the smart contract in the contract node, and determining the first evaluation value other than the abnormal evaluation value in the first evaluation value as the evaluation value to be processed.

[0125] Specifically, the contract node can perform mean processing on the first evaluation value through the smart contract in the contract node to obtain a first average value between the first evaluation values. Then, the contract node can also determine the difference between each first evaluation value in the first evaluation value and the first average value, and determine the first evaluation value whose difference is greater than the abnormal threshold as the abnormal evaluation value. Further, the contract node can exclude the abnormal evaluation value from the first evaluation value, and determine the first evaluation value excluding the abnormal evaluation value as the evaluation value to be processed.

[0126] It should be understood that the contract node can obtain the Figure 4 The first evaluation values ​​determined by the business data in area B (i.e., the area where the classical Chinese reading is located) shown are 9 points, 8 points, and 4 points. The contract node can perform mean processing on the received first evaluation values ​​through the smart contract in the contract node, so as to obtain the average value between the first evaluation values ​​(i.e., 7 points). Among them, the embodiment of the present application can refer to the average value obtained after mean processing of the first evaluation values ​​determined for multiple reading terminals as the first average value. It should be understood that the contract node can determine the difference between each of the first evaluation values ​​determined by the three reading terminals and the first average value. Among them, as Figure 2 As shown, the difference between the first evaluation value (9 points) determined by the reading terminal A and the first average value is 2 points, the difference between the first evaluation value (8 points) determined by the reading terminal B and the first average value is 1 point, and the difference between the first evaluation value (4 points) determined by the reading terminal C and the first average value is 3 points.

[0127] It should be understood that the embodiment of the present application can pre-set an abnormal threshold (for example, 2 points), and the abnormal threshold is used to determine the abnormal evaluation value between the first evaluation values ​​determined by multiple reading terminals. It is understandable that the contract node can determine the first evaluation value whose difference is greater than the abnormal threshold as the abnormal evaluation value. Therefore, the contract node can determine the first evaluation value (4 points) determined by the reading terminal C as the abnormal evaluation value. Further, the contract node can exclude the abnormal evaluation value from the above-mentioned first evaluation value, and determine the first evaluation value excluding the abnormal evaluation value as the evaluation value to be processed, which is the first evaluation value (9 points) determined by the reading terminal A and the first evaluation value (8 points) determined by the reading terminal B.

[0128] S103, calling the smart contract and sending the business data in the area to be processed to the review terminal.

[0129] Specifically, after removing the abnormal evaluation value, the contract node sends the business data in the pending area corresponding to the abnormal evaluation value to the audit terminal by calling the smart contract. The audit terminal can be the above Figure 2 The corresponding audit terminal can be the above Figure 1b The corresponding audit terminal 4000.

[0130] It should be understood that Figure 2 As shown, the contract node removes abnormal evaluation values ​​(i.e., the reading terminal C is for Figure 4 After the first evaluation value determined by the business data in area B shown in the figure is 4 points, the business data in area B can be sent to the audit terminal associated with area B. At this time, the auditor corresponding to the audit terminal can evaluate the business data in area B. In other words, the auditor can evaluate the answer filled in by the examinee A in the area where the classical Chinese reading is located.

[0131] S104, obtaining a second evaluation value determined for the business data in the area to be processed and returned by the audit terminal.

[0132] Specifically, the audit terminal can send the evaluation value determined for the business data in the area to be processed to the contract node. In this embodiment of the present application, the evaluation value determined by the audit terminal for the business data in the area to be processed can be referred to as the second evaluation value. Further, the contract node can receive the second evaluation value sent by the audit terminal.

[0133] S105: Based on the second evaluation value and the evaluation value to be processed, determine the target evaluation value corresponding to the business data in the area to be processed, and write the associated business data information associated with the target evaluation value into the blockchain corresponding to the blockchain network.

[0134] Specifically, the contract node can obtain the first evaluation value with the maximum evaluation value and the first evaluation value with the minimum evaluation value from the evaluation value to be processed, and determine the evaluation range formed by the first evaluation value with the maximum evaluation value and the first evaluation value with the minimum evaluation value. Further, the contract node can determine the belonging relationship between the second evaluation value and the evaluation range, so as to determine the target evaluation value corresponding to the business data in the area to be processed, and write the associated business data information associated with the target evaluation value into the blockchain corresponding to the blockchain network.

[0135] It should be understood that Figure 2 As shown, the contract node can determine from the above-mentioned pending evaluation values ​​that the first evaluation value with the maximum evaluation value is 9 points, and the first evaluation value with the minimum evaluation value is 8 points, so the evaluation range can be between 8 points and 9 points. It can be understood that the evaluation range includes 8 points and 9 points.

[0136] If Figure 2 If the second evaluation value (for example, 8 points) determined by the review terminal shown belongs to the evaluation range, the contract node can perform mean processing on the second evaluation value and the evaluation value to be processed, so as to obtain the average value between the second evaluation value and the evaluation value to be processed (that is, 8.3 points). Among them, the embodiment of the present application can refer to the average value obtained after the second evaluation value and the evaluation value to be processed are averaged as the second average value. It can be understood that when determining the second average value, there may be a situation where the second average value is a non-integer. At this time, the contract node can approximate the second average value (for example, rounding), so as to use the approximate second average value as the target evaluation value corresponding to the business data in the area to be processed. In other words, the contract node can determine that the score obtained by the examinee A in the classical Chinese reading part is 8 points.

[0137] If Figure 2 If the second evaluation value (e.g., 10 points) determined by the review terminal shown does not fall within the evaluation range, the contract node can trigger the review mechanism in the smart contract to distribute the business data in the pending area to Figure 2 The three reading terminals in the reading terminal cluster shown in FIG. In other words, the contract node can Figure 4The business data in area B shown is sent again to reading terminal A, reading terminal B and reading terminal C, so that the users corresponding to the three reading terminals can re-evaluate the answers filled in by the examinee A in the area where the classical Chinese reading is located. Among them, the embodiment of the present application can determine the evaluation value determined by multiple reading terminals in the reading terminal cluster again for the business data in the pending area in the first assessment file as the third evaluation value. It can be understood that the contract node can receive the third evaluation value determined by the three reading terminals, and update the above-mentioned first evaluation value based on the third evaluation value. At this time, the contract node can perform the same steps as the above-mentioned first evaluation value on the third evaluation value through the smart contract in the contract node, so that the target evaluation value of the business data in the pending area can be determined, which will not be repeated here.

[0138] Optional, if Figure 2 If there is no abnormal evaluation value in the first evaluation value obtained by the contract node shown in the figure, the contract node can perform mean processing on the first evaluation value to obtain a first average value between the first evaluation values. At this time, the first average value can be used as Figure 4 The target evaluation value of the business data in area B is shown. For example, Figure 2 The first evaluation value determined by the reading terminal A for the business data in area B is 8 points, the first evaluation value determined by the reading terminal B for the business data in area B is 7 points, and the first evaluation value determined by the reading terminal C for the business data in area B is 8 points. At this time, the contract node can determine that the first average value corresponding to the first evaluation value is 7.67 points, and the first average value is approximated, and the first average value after approximation is 8 points. At this time, the contract node can determine the difference between each first evaluation value and the first average value. Since the abnormal threshold is 2 points, the contract node does not determine the abnormal evaluation value in the first evaluation value. It should be understood that the contract node can use the first average value after approximation as the target evaluation value of the business data corresponding to the area B (i.e., 8 points). In other words, the contract node can determine that the score obtained by the candidate A in the classical Chinese reading part is 8 points.

[0139] Furthermore, the contract node can obtain Figure 2 Each reading terminal in the reading terminal cluster shown is Figure 4 The reading time of the business data in area B shown in the figure is determined, and the associated business data information associated with the target evaluation value is determined according to the reading time, the abnormal evaluation value, the pending evaluation value, the second evaluation value, and the target evaluation value. The associated business data information is used to record the determination process of the target evaluation value of the business data in the pending area of ​​the first assessment file. Figure 2As shown, the contract node can upload the associated business data information to the chain. Due to the immutability of blockchain technology, the reliability of the associated business data information can be improved.

[0140] Among them, blockchain 1 can be the above Figure 1a The blockchain corresponding to the blockchain network in the contract node, the blockchain 1 can be an identical blockchain shared by each node in the blockchain network corresponding to the contract node, and each node can obtain the information stored in the blockchain in the blockchain 1. The blockchain 1 includes blocks 10a, 10b, ..., 10n and a target block, and the block 10a can be called the genesis block of the blockchain 1. The target block in the blockchain 1 contains the above-mentioned associated business data information.

[0141] Among them, the contract node can write the associated business data information into the blockchain in the blockchain network corresponding to the contract node. In other words, the contract node can obtain the block 10n with the maximum generation timestamp from the blockchain 1. Further, the contract node can generate a target block to be written into the blockchain 1 based on the associated business data information. At this time, the contract node broadcasts the target block containing the associated business data information to all blockchain nodes in the blockchain network (for example, consensus nodes used for consensus processing). When it is determined that all blockchain nodes have reached a consensus, the target block can be written into the above-mentioned blockchain 1, that is, the target block is used as the next block of block 10n.

[0142] In an embodiment of the present application, a contract node in a blockchain network can obtain a first evaluation value determined for business data in an area to be processed and sent by multiple reading terminals. The area to be processed is an area in the first assessment file outputted in each reading terminal. The contract node can determine an abnormal evaluation value from the first evaluation value through a smart contract in the contract node, and determine the first evaluation value other than the abnormal evaluation value in the first evaluation value as the evaluation value to be processed. At this time, the contract node can call the smart contract, send the business data in the area to be processed to the audit terminal, and obtain the second evaluation value determined for the business data in the area to be processed returned by the audit terminal. Furthermore, the contract node can determine the target evaluation value corresponding to the business data in the area to be processed based on the second evaluation value and the evaluation value to be processed, and write the associated business data information associated with the target evaluation value into the blockchain corresponding to the blockchain network. It can be seen from this that the contract nodes in the blockchain network can call smart contracts to determine the target evaluation value of the business data in the pending area of ​​the first assessment file, and write the associated business data information associated with the target evaluation value into the blockchain corresponding to the blockchain network. Since the business data information on the blockchain is tamper-proof, the reliability of the target evaluation value, the business data, can be improved.

[0143] For further information, see Figure 5 , is a flow chart of another data processing method provided in an embodiment of the present application. The method is applied to a contract node in a blockchain network. Figure 5 As shown, the method may include:

[0144] S201, obtaining first evaluation values ​​determined for business data in a to-be-processed area and sent by a plurality of viewing terminals.

[0145] Specifically, the contract node in the blockchain network can send the pending area of ​​the first electronic assessment file to multiple reading terminals associated with the pending area. Further, each of the multiple reading terminals can determine a first evaluation value for the business data in the pending area, and send the first evaluation value to the contract node. The pending area is the area in the first assessment file output by each reading terminal. The first assessment file refers to the electronic assessment file corresponding to the pending area that each reading terminal is reading at this moment.

[0146] S202, determining an abnormal evaluation value from the first evaluation value through the smart contract in the contract node, and determining the first evaluation value other than the abnormal evaluation value in the first evaluation value as the evaluation value to be processed.

[0147] Specifically, the contract node can perform mean processing on the first evaluation value through the smart contract in the contract node to obtain a first average value between the first evaluation values. Then, the contract node can also determine the difference between each first evaluation value in the first evaluation value and the first average value, and determine the first evaluation value whose difference is greater than the abnormal threshold as the abnormal evaluation value. Further, the contract node can exclude the abnormal evaluation value from the first evaluation value, and determine the first evaluation value excluding the abnormal evaluation value as the evaluation value to be processed.

[0148] S203, calling the smart contract and sending the business data in the area to be processed to the review terminal.

[0149] Specifically, after removing the abnormal evaluation value, the contract node sends the business data in the pending area corresponding to the abnormal evaluation value to the audit terminal by calling the smart contract. The audit terminal can be the above Figure 2 The corresponding audit terminal can be the above Figure 1b The corresponding audit terminal 4000.

[0150] S204: Obtain a second evaluation value returned by the audit terminal and determined for the business data in the area to be processed.

[0151] Specifically, the audit terminal can send the evaluation value determined for the business data in the area to be processed to the contract node. In this embodiment of the present application, the evaluation value determined by the audit terminal for the business data in the area to be processed can be referred to as the second evaluation value. Further, the contract node can receive the second evaluation value sent by the audit terminal.

[0152] S205: Based on the second evaluation value and the evaluation value to be processed, determine the target evaluation value corresponding to the business data in the area to be processed, and write the associated business data information associated with the target evaluation value into the blockchain corresponding to the blockchain network.

[0153] Specifically, the contract node can obtain the first evaluation value with the maximum evaluation value and the first evaluation value with the minimum evaluation value from the evaluation value to be processed, and determine the evaluation range formed by the first evaluation value with the maximum evaluation value and the first evaluation value with the minimum evaluation value. Further, the contract node can determine the belonging relationship between the second evaluation value and the evaluation range, thereby determining the target evaluation value corresponding to the business data in the area to be processed, and write the associated business data information associated with the target evaluation value into the blockchain corresponding to the blockchain network.

[0154] The specific implementation of steps S201 to S205 can be found in the above Figure 3The description of step S101 to step S105 in the corresponding embodiment will not be repeated here.

[0155] S206: Acquire at least one second assessment file associated with the first assessment file, and determine the viewing terminal associated with the abnormal evaluation value as a terminal to be monitored.

[0156] Specifically, the contract node may obtain at least one second assessment file having the same to-be-processed region as the first assessment file. Figure 1b In the process of determining the first evaluation value for each reading terminal in the reading terminal cluster shown, the contract node can determine the reading terminal associated with the abnormal evaluation value as the terminal to be monitored. In this embodiment of the application, other electronic assessment files having the same area to be processed as the first assessment file can be collectively referred to as second assessment files.

[0157] S207, monitoring the fourth evaluation value determined by the terminal to be monitored for each second assessment file through the smart contract.

[0158] Specifically, after the reading terminal associated with the area to be processed determines the first evaluation value for the area to be processed, the reading terminal may continue to determine the evaluation value for the business data in the area to be processed of the second assessment file. In this embodiment of the present application, the evaluation value determined by the reading terminal for the business data in the area to be processed of the second assessment file may be referred to as the fourth evaluation value. Furthermore, the contract node may monitor the fourth evaluation value determined by the monitored terminal for the business data in the area to be processed of each second assessment file through the smart contract.

[0159] S208: Within the target time period, count the number of times the fourth evaluation value is the abnormal evaluation value.

[0160] Specifically, within the target duration, the contract node can count the number of times the fourth evaluation value determined by the monitored terminal is an abnormal evaluation value. The target duration refers to the duration taken by the monitored terminal to determine the fourth evaluation value for the business data in the to-be-processed area of ​​all second assessment files.

[0161] S209: Determine the behavior confidence information corresponding to the terminal to be monitored based on the number of times and the reading duration of each second assessment file.

[0162] Specifically, the contract node can determine the behavior confidence information of the user corresponding to the reading terminal according to the number of times the fourth evaluation value determined by the terminal to be monitored is an abnormal evaluation value and the reading time of each second assessment file. The behavior confidence information is used to indicate that the user corresponding to the terminal to be detected has the authority to read the assessment file.

[0163] For further understanding, please refer to Figure 6 , is a schematic diagram of a scenario for determining the behavior confidence information corresponding to the terminal to be monitored provided by an embodiment of the present application. Figure 6 As shown, node A can be the above Figure 2 The corresponding contract node can be the above Figure 1b The corresponding node 1000a may be the above-mentioned node 1000a. Figure 1a The node 1000a in the blockchain node system shown. The reading terminal cluster can be the above Figure 2 The corresponding reading terminal cluster may specifically include reading terminal A, reading terminal B and reading terminal C.

[0164] like Figure 6 As shown, the node A can obtain at least one electronic assessment file in the second assessment file 200, wherein each electronic assessment file in the second assessment file 200 is identical to the first assessment file ( Figure 4 The electronic assessment file 100a) shown in FIG. 1 has electronic assessment files of the same area to be processed (area B). It should be understood that the node A can send each electronic assessment file in the second assessment file 200 to each reading terminal in the reading terminal cluster. In other words, each reading terminal in the reading terminal cluster can send each electronic assessment file in the second assessment file 200 to each reading terminal in the reading terminal cluster. Figure 4 After determining the first evaluation value for the electronic assessment file 100a (first assessment file) shown in FIG. 1 , a fourth evaluation value may be determined for each electronic assessment file in the second assessment file 200. The second assessment file 200 may include at least one electronic assessment file. Figure 6 As shown, the second assessment file 200 may specifically include: an electronic assessment file 200a, an electronic assessment file 200b, ..., an electronic assessment file 200n.

[0165] It should be understood that when each reading terminal in the reading terminal cluster determines the first evaluation value for the first assessment file, the node A can determine the reading terminal associated with the abnormal evaluation value as the terminal to be monitored. For example, the node A can determine that the first evaluation value determined by the reading terminal C in the reading terminal cluster is an abnormal evaluation value. At this time, the node A can determine the reading terminal C as the terminal to be monitored.

[0166] Further, after determining the first evaluation value for the business data in area B of the first assessment file, the reading terminal C may continue to determine the fourth evaluation value for the business data in area B of each electronic assessment file in the second assessment file 200. At this time, the node A may monitor the fourth evaluation value determined by the reading terminal C through the smart contract. The node A may count the number of times the fourth evaluation value determined by the reading terminal C is an abnormal evaluation value within the target duration. The target duration refers to the duration spent by the reading terminal C to determine the business data in the to-be-processed area of ​​all electronic assessment files in the second assessment file 200.

[0167] It should be understood that the node A can determine the behavior confidence information corresponding to the reading terminal C based on the number of times and the reading time of the reading terminal C for each electronic assessment file in the second assessment file 200. It can be understood that if the reading terminal C has more abnormal evaluation values ​​within the target time, and the shorter the reading time for the business data in the area B, the behavior confidence information of the user C corresponding to the reading terminal C will be lower. When the behavior confidence information of the user C is lower than the preset judgment threshold, the reading qualification of the user C is cancelled. In other words, the user C does not have the authority to read the target test paper. Among them, the node A can improve the accuracy and efficiency of the business data in the area to be processed by determining the behavior confidence information of the reading terminal corresponding to the abnormal evaluation value.

[0168] In an embodiment of the present application, a contract node in a blockchain network can obtain a first evaluation value determined for business data in an area to be processed and sent by multiple reading terminals. The area to be processed is an area in the first assessment file outputted in each reading terminal. The contract node can determine an abnormal evaluation value from the first evaluation value through a smart contract in the contract node, and determine the first evaluation value other than the abnormal evaluation value in the first evaluation value as the evaluation value to be processed. At this time, the contract node can call the smart contract, send the business data in the area to be processed to the audit terminal, and obtain the second evaluation value determined for the business data in the area to be processed returned by the audit terminal. Furthermore, the contract node can determine the target evaluation value corresponding to the business data in the area to be processed based on the second evaluation value and the evaluation value to be processed, and write the associated business data information associated with the target evaluation value into the blockchain corresponding to the blockchain network. It can be seen from this that the contract nodes in the blockchain network can call smart contracts to determine the target evaluation value of the business data in the pending area of ​​the first assessment file, and write the associated business data information associated with the target evaluation value into the blockchain corresponding to the blockchain network. Since the business data information on the blockchain is tamper-proof, the reliability of the target evaluation value, the business data, can be improved.

[0169] For further information, see Figure 7 , is a schematic diagram of the structure of a data processing device provided in an embodiment of the present application. The data processing device 1 can be applied to a contract node in a blockchain network, and the contract node can be the above Figure 2 The data processing device 1 may include: a first acquisition module 10, a first determination module 20, a calling module 30, a second acquisition module 40, a writing module 50, a second determination module 60, a monitoring module 70, a statistics module 80 and a third determination module 90.

[0170] The first acquisition module 10 is used to acquire first evaluation values ​​determined for business data in a to-be-processed area sent by multiple reading terminals; the to-be-processed area is an area in the first assessment file outputted by each reading terminal.
