[0025] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. To make the objectives, technical solutions, and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only configured to explain the present invention and are not configured to limit the present invention. For those skilled in the art, the present invention can be implemented without some of these specific details. The following description of the embodiments is only to provide a better understanding of the present invention by showing examples of the present invention.

[0026] It should be noted that, in this document, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprise", "include" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, the elements defined by the statement "comprising..." do not exclude the presence of additional identical elements in the process, method, article or device including the said elements.

[0027] The data processing method provided by the present invention can be applied to an architecture such as Figures 1 to 4 and will be described in detail in combination with Figures 1 to 4 specifically.

[0028] Figure 1 FIG. shows an architecture diagram of data processing provided by an embodiment of the present invention. As Figure 1 shown, this architecture can be applied to a blockchain network. The architecture diagram may include a user contract 110 and a regulatory encapsulation interface 120, where the regulatory encapsulation interface 120 includes a call to a regulatory instance 121.

[0029] Among them, the user contract 110 can communicate with a data query node. The data query node can be an electronic device or a server. The electronic device can be a device with a communication function such as a mobile phone, a tablet computer, a desktop computer, a vehicle-mounted terminal, and a wearable device. The server can be a cloud server or a server cluster and other devices with storage and computing functions.

[0030] In some embodiments, the blockchain network can be a Blockchain-based Service Network (BSN).

[0031] Continue to refer to Figure 1, the data query node can respond to a data query instruction issued by a user for querying target transaction data, generate a data query request corresponding to the data query instruction, and call a supervision encapsulation interface 120 through a user contract 110, so that a called supervision instance 121 receives the data query request for querying the target transaction data.

[0032] The called supervision instance 121 can receive the data query request sent by the data query node, and in response to the data query request, when determining that the target transaction data is compliant data, obtain the target transaction data to send the target transaction data to the data query node.

[0033] Therefore, after receiving the data query request sent by the data query node, only the compliant data can be sent to the data query node to avoid the leakage of non-compliant transaction data.

[0034] Figure 2 shows an architecture diagram of data processing provided by another embodiment of the present invention. As Figure 2 shown, the architecture diagram may include a user contract 110, a supervision encapsulation interface 120, and a status database 130. Among them, the supervision encapsulation interface 120 may be formed by encapsulating a called supervision instance 121 and a native data interface 122.

[0035] It should be noted that Figure 2 the principles of the user contract 110 and the called supervision instance 121 in the shown architecture are similar to those of the user contract 110 and the called supervision instance 121 in the Figure 1 shown architecture, and will not be elaborated here.

[0036] The status database 130 may be a database in a distributed ledger. The called supervision instance 121 can communicate with the status database 130 by calling the native data interface 122, so as to implement the acquisition and storage of compliance status marker values.

[0037] The status database 130 may pre-store multiple compliance status marker values. The called supervision instance 121 can call the status database to make the status database query the compliance status marker value corresponding to the target string, and after receiving the compliance status marker value corresponding to the target transaction data, when the received compliance status marker value is the target value, determine that the target transaction data is compliant data.

[0038] Therefore, the compliance status marker value corresponding to each transaction data that has been chained can be stored in the status database, and the compliance status marker value can be used to determine whether each transaction data that has been chained is compliant data.

[0039] Figure 3 shows an architecture diagram of data processing provided by yet another embodiment of the present invention. AsFigure 3 As shown, the architecture diagram may include a user contract 110, a regulatory encapsulation interface 120, a state database 130, and a regulatory contract 140. Among them, the regulatory encapsulation interface 120 may be formed by encapsulating a call regulatory instance 121 and a native data interface 122.

[0040] It should be noted that Figure 3 the principles of the user contract 110, the state database 130, and the call regulatory instance 121 in the architecture shown Figure 2 are similar to those of the user contract 110, the state database 130, and the call regulatory instance 121 in the architecture shown, and will not be elaborated here.

[0041] The call regulatory instance 121 can also communicate with the regulatory contract 140. The call regulatory instance 121 can also communicate with the state database 130 by calling the native data interface 122, so as to realize the acquisition and storage of target transaction data.

[0042] In some embodiments, before storing the target transaction data in the state database 130 through the native data interface 122, the call regulatory instance 121 can also call the regulatory contract 140 to detect the target data in the target transaction data through the regulatory contract 140 to obtain a regulatory result, so that the call regulatory instance 121 can store the compliance status flag value corresponding to the regulatory result and the target transaction data in the state database 130 when the regulatory result is that the target data does not exist in the target transaction data.

[0043] In other embodiments, when the target transaction data is transaction data that has been chained, the call regulatory instance 121 can also call the regulatory contract 140 to detect the target data in the target transaction data through the regulatory contract 140 to obtain a regulatory result, so that the call regulatory instance 121 can store the compliance status flag value corresponding to the regulatory result and the target transaction data in the state database 130.

[0044] Among them, the target data can be a preset keyword, such as a sensitive word.

[0045] Therefore, before or after chaining the transaction data, it is possible to screen for target data such as sensitive words in the transaction data to avoid leakage of the transaction data.

[0046] Figure 4 shows an architecture diagram of data processing provided by still another embodiment of the present invention. As Figure 3As shown in the figure, the architecture diagram may include a user contract 110, a regulatory encapsulation interface 120, a state database 130, and a regulatory system server 150 of an offline regulatory agency. Among them, the regulatory encapsulation interface 120 includes a call regulatory instance 121 and a native data interface 122, and the call regulatory instance 121 is also communicatively connected to the regulatory system server 150.

[0047] It should be noted that Figure 4 The principles of the user contract 110, the state database 130, and the call regulatory instance 121 in the architecture shown are similar to those of the user contract 110, the state database 130, and the call regulatory instance 121 in the architecture shown, and will not be elaborated here. Figure 2 shown, and will not be elaborated here.

[0048] In some embodiments, before storing the target transaction data into the state database 130 through the native data interface 122, the call regulatory instance 121 may also send the target transaction data to the regulatory system server 150, so that the offline regulatory agency can use the regulatory system server 150 for automatic or manual supervision, obtain the supervision result corresponding to the target transaction data, and feedback the supervision result to the call regulatory instance 121. The call regulatory instance 121 may store the compliance status mark value corresponding to the supervision result and the target transaction data into the state database 130 when the supervision result is that the target data does not exist in the target transaction data.

[0049] In other embodiments, when the target transaction data is transaction data that has been chained, the call regulatory instance 121 may send the target transaction data to the regulatory system server 150, so that the offline regulatory agency can use the regulatory system server 150 for automatic or manual supervision, obtain the supervision result corresponding to the target transaction data, and feedback the supervision result to the call regulatory instance 121. The call regulatory instance 121 may determine the compliance status mark value corresponding to the supervision result and store it into the state database.

[0050] Therefore, the offline regulatory agency can be used to supervise the transaction data before or after chaining, and then determine whether the transaction data is compliant data to avoid the leakage of transaction data.

[0051] Figure 5 shows a schematic flowchart of a data processing method provided by an embodiment of the present invention.

[0052] In some embodiments of the present invention, Figure 5 the method shown may be executed by Figures 1 to 4 the call regulatory instance 120 in the architecture shown, or may be executed by a smart contract engine, and is not limited here.

[0053] As Figure 5As shown, the data processing method may include the following steps.

[0054] S510. Receive a data query request sent by a data query node; wherein, the data query request is used to query target transaction data.

[0055] In some embodiments of the present invention, the data query node may call a supervision encapsulation interface through a user contract, so that the called supervision instance receives the data query request through the supervision encapsulation interface.

[0056] S520. In response to the data query request, when it is determined that the target transaction data is compliant data, obtain the target transaction data.

[0057] In some embodiments of the present invention, the target transaction data may be stored in the form of key-value pairs. Wherein, the key of the key-value pair may be a target string, the value of the key-value pair may be the target transaction data, and the target string may be used to index the target transaction data.

[0058] Further, the data query request may carry a target string, and the target string may be associated with a stored compliance status flag value, and the compliance status flag value may be used to determine that the target transaction data is compliant data. When the compliance status flag value is the target value, it can be determined that the target transaction data is compliant data; when the compliance status flag value is not the target value, it can be determined that the target transaction data is not compliant data.

[0059] Taking the target value as 1 as an example, when the compliance status flag value is 1, it can be determined that the target transaction data is compliant data, and when the compliance status flag value is 0, it can be determined that the target transaction data is not compliant data.

[0060] In these embodiments, before S520, the data processing method may further include:

[0061] Parse the data query request to obtain data query request information; wherein, the data query request information includes the target string corresponding to the target transaction data;

[0062] Obtain the compliance status flag value corresponding to the target string;

[0063] Wherein, determining that the target transaction data is compliant data may include:

[0064] When the compliance status flag value is the target value, determine that the target transaction data is compliant data.

[0065] Specifically, after receiving a data query request, the calling supervision instance can parse the data query request to obtain data query request information, and then obtain the target string carried in the data query request from the data query request information. Then, the calling supervision instance can query the compliance status flag value corresponding to the target string, and determine that the target transaction data is compliant data when it is determined that the compliance status flag value is the target value.

[0066] In some embodiments, the target string and the compliance status flag value corresponding to the target string can be associated and stored within the calling supervision instance.

[0067] In other embodiments, the target string and the compliance status flag value corresponding to the target string can be associated and stored within the state database of the distributed ledger.

[0068] In these embodiments, optionally, before obtaining the compliance status flag value corresponding to the target string, the data processing method may further include:

[0069] Call the state database to enable the state database to query the compliance status flag value corresponding to the target string;

[0070] Correspondingly, obtaining the compliance status flag value corresponding to the target string may include:

[0071] Obtain the compliance status flag value corresponding to the target string fed back by the state database.

[0072] Specifically, the calling supervision instance can call the state database according to the target string to enable the state database to query the compliance status flag value corresponding to the target string. The calling supervision instance can receive the compliance status flag value corresponding to the target string fed back by the state database to achieve the acquisition of the compliance status flag value corresponding to the target string.

[0073] Furthermore, the calling supervision instance can call the state database through the native data interface 122 according to the target string.

[0074] In these embodiments, optionally, before obtaining the target transaction data, the data processing method may further include:

[0075] Call the state database to enable the state database to query the target transaction data corresponding to the target string;

[0076] Correspondingly, obtaining the target transaction data may include:

[0077] Obtain the target transaction data fed back by the state database.

[0078] Specifically, the calling supervision instance can call the status database according to the target string, so that the status database indexes the target transaction data corresponding to the target string among multiple pre-stored transaction data, and then feeds back the target transaction data to the calling supervision instance, so that the calling supervision instance receives the target transaction data fed back by the status database.

[0079] Specifically, the calling supervision instance can call the status database through the native data interface 122 according to the target string.

[0080] S530. Send the target transaction data to the data query node.

[0081] In an embodiment of the present invention, after receiving the data query request sent by the data query node for querying the target transaction data, if it is determined that the target transaction data is compliant data, the target transaction data is obtained and sent to the data query node. Therefore, after receiving the data query request sent by the data query node, only the compliant data can be sent to the data query node, avoiding the leakage of non-compliant transaction data.

[0082] In another embodiment of the present invention, in order to further avoid the leakage of transaction data, after S510, the data processing method may further include:

[0083] In response to the data query request, when it is determined that the target transaction data is not compliant data, a first prompt message is sent to the data query node; wherein, the first prompt message is used to prompt that the target transaction data is non-compliant.

[0084] Thus, the calling supervision instance can, when determining that the target transaction data is not compliant data, prompt the user through the first prompt message that the target transaction data to be queried is non-compliant, so as to further avoid the leakage of transaction data.

[0085] Wherein, the first prompt message may include information for characterizing "data violation, unable to query" to prompt the user that the target transaction data to be queried is non-compliant.

[0086] Optionally, the calling supervision instance can send the first prompt message to the data query node through the user contract.

[0087] Further, the calling supervision instance can call the user contract through the supervision encapsulation interface to send the first prompt message to the data query node.

[0088] In some embodiments of the present invention, in order to further avoid the leakage of transaction data, after S510, the data processing method may further include:

[0089] In response to a data query request, when it is determined that the target transaction data is not compliant data, the target transaction data is refused to be sent to the data query node.

[0090] Thus, when it is determined that the target transaction data is not compliant data, the calling supervision instance can refrain from feeding back the target transaction data to the data query node, so as to further avoid the leakage of transaction data.

[0091] In another embodiment of the present invention, when the target transaction data is stored data, that is, when the target transaction data is on-chain transaction data, in order to further avoid the leakage of transaction data, before S510, the data processing method may further include:

[0092] Sending the target transaction data to the supervision system server so that the supervision system server feeds back the supervision result corresponding to the target transaction data;

[0093] Receiving the supervision result fed back by the supervision system server;

[0094] Determining the compliance status flag value corresponding to the supervision result.

[0095] Specifically, if the calling supervision instance is communicatively connected to the supervision system server, the calling supervision instance can send the target transaction data to the supervision system server of the offline supervision agency, so that the offline supervision agency can use the supervision system server for automatic or manual supervision to obtain the supervision result corresponding to the target transaction data, and feed back the supervision result to the calling supervision instance.

[0096] In some embodiments, the supervision system server may input the target transaction data into a pre-trained compliance detection model to obtain the supervision result corresponding to the target transaction data, so as to achieve automatic supervision.

[0097] In other embodiments, the supervision system server may push the target transaction data to the mobile terminal and the web terminal, so that the supervisors of the offline supervision agency can perform manual supervision on the target transaction data to obtain the supervision result corresponding to the target transaction data, so as to achieve manual supervision.

[0098] Specifically, when the supervision result indicates that the target transaction data is compliant data, the calling supervision instance can determine that the compliance status flag value is the target value; when the supervision result indicates that the target transaction data is not compliant data, the calling supervision instance can determine that the compliance status flag value is not the target value.

[0099] In other embodiments, before sending the target transaction data to the supervision system server, the data processing method may further include:

[0100] Generating a target event according to the target transaction data;

[0101] Accordingly, sending the target transaction data to the supervision system server may include:

[0102] Sending the target event to the supervision system server.

[0103] Specifically, the supervision system server may also subscribe to the events in the invoked supervision instance. For example, when the invoked supervision instance detects that there is target transaction data in the on-chain transaction data that has not been supervised, the invoked supervision instance will generate a target event based on the target transaction data and send the target event to the supervision system server, so that the supervision system server can obtain the target transaction data and conduct offline supervision.

[0104] In some other embodiments of the present invention, when the target transaction data is stored data, that is, when the target transaction data is on-chain transaction data, in order to further avoid the leakage of transaction data, before S510, the data processing method may further include:

[0105] Invoking a supervision contract to enable the supervision contract to detect target data in the target transaction data and obtain a supervision result corresponding to the target transaction data;

[0106] Receiving the supervision result fed back by the supervision contract;

[0107] Determining a compliance status flag value corresponding to the supervision result.

[0108] Specifically, if the invoked supervision instance has a callable supervision contract, the invoked supervision instance may call the supervision contract to enable the supervision contract to detect target data in the target transaction data and obtain a supervision result corresponding to the target transaction data. When it is detected that there is no target data in the target transaction data, the supervision result indicates that the target transaction data is compliant data; when it is detected that there is target data in the target transaction data, the supervision result indicates that the target transaction data is not compliant data.

[0109] After the invoked supervision instance receives the detection result fed back by the supervision contract, when the supervision result indicates that the target transaction data is compliant data, it may determine that the compliance status flag value is the target value; when the supervision result indicates that the target transaction data is not compliant data, it may determine that the compliance status flag value is not the target value.

[0110] Therefore, in the embodiments of the present invention, the on-chain transaction data can be supervised. If the transaction data is non-compliant, the non-compliant transaction data is marked by setting the compliance status flag value, thereby restricting the access of the data query node to the non-compliant transaction data. In addition, the supervision behavior is flexibly configurable and can be upgraded or updated at any time.

[0111] In some embodiments, after determining the compliance status flag value corresponding to the supervision result, the data processing method may further include:

[0112] Obtain the target string corresponding to the target transaction data;

[0113] Associate and store the target string and the compliance status flag value in the status database.

[0114] Specifically, after determining the compliance status flag value corresponding to the supervision result, the invoked supervision instance may send it and the target string corresponding to the target transaction data to the status database, so that the status database associates and stores the target string and the compliance status flag value corresponding to the target string in the status database.

[0115] In some other embodiments, after determining the compliance status flag value corresponding to the supervision result, the invoked supervision instance may also associate and store it with the target string corresponding to the target transaction data locally.

[0116] In yet another implementation manner of the present invention, before receiving the data query request sent by the data query node, the data processing method may further include:

[0117] Receive the data storage request sent by the data storage node;

[0118] In response to the data storage request, parse the data storage request to obtain the data storage request information; wherein, the data storage request information includes the target string and the target transaction data;

[0119] Associate and store the target string and the target transaction data in the status database.

[0120] Specifically, after receiving the data storage request sent by the data storage node, the invoked supervision instance may parse the data storage request to obtain the target string and the target transaction data to be stored in the data storage request information, and then associate and store the target string and the target transaction data in the status database.

[0121] In some embodiments of the present invention, in order to further avoid the leakage of transaction data, before associating and storing the target string and the target transaction data in the status database, the data processing method may further include:

[0122] Invoke the supervision contract to enable the supervision contract to detect the target data in the target transaction data to obtain the supervision result corresponding to the target transaction data;

[0123] Receive the supervision result fed back by the supervision contract;

[0124] Determine the compliance status flag value corresponding to the supervision result;

[0125] Correspondingly, associatively storing the target string and the target transaction data in the status database may include:

[0126] When the compliance status flag value corresponding to the supervision result is the target value, associatively store the compliance status flag value and the target transaction data with the target string in the status database respectively.

[0127] Optionally, if the invoked supervision instance has a callable supervision contract, the invoked supervision instance may call the supervision contract, so that the supervision contract detects the target data in the target transaction data based on a preset supervision rule to obtain a supervision result corresponding to the target transaction data. When it is detected that the target data does not exist in the target transaction data, the supervision result indicates that the target transaction data is compliant data; when it is detected that the target data exists in the target transaction data, the supervision result indicates that the target transaction data is not compliant data. After receiving the supervision result fed back by the supervision contract, the invoked supervision instance may determine the compliance status flag value corresponding to the supervision result. When the supervision result indicates that the target transaction data is compliant data, the invoked supervision instance may determine that the compliance status flag value is the target value; when the supervision result indicates that the target transaction data is not compliant data, it may be determined that the compliance status flag value is not the target value. Finally, when the compliance status flag value corresponding to the supervision result is the target value, the invoked supervision instance may associatively store the target string and the target transaction data in the status database, thereby only saving the transaction data initially determined to have no leakage risk by the supervision contract in the status database, thereby avoiding the leakage of transaction data.

[0128] In some other embodiments of the present invention, in order to further avoid the leakage of transaction data, before associatively storing the target string and the target transaction data in the status database, the data processing method may further include:

[0129] Send the target transaction data to the supervision system server so that the supervision system server feeds back the supervision result corresponding to the target transaction data;

[0130] Receive the supervision result fed back by the supervision system server;

[0131] Determine the compliance status flag value corresponding to the supervision result;

[0132] Correspondingly, associatively storing the target string and the target transaction data in the status database may specifically include:

[0133] When the compliance status flag value corresponding to the supervision result is the target value, associatively store the compliance status flag value and the target transaction data with the target string in the status database respectively.

[0134] Optionally, if the invoked supervision instance is communicatively connected to the supervision system server, the invoked supervision instance may send the target transaction data to the supervision system server of the offline supervision agency, so that the offline supervision agency can use the supervision system server for automatic or manual supervision to obtain the supervision result corresponding to the target transaction data, and feedback the supervision result to the invoked supervision instance. When the supervision result indicates that the target transaction data is compliant data, the invoked supervision instance may determine that the compliance status flag value is the target value; when the supervision result indicates that the target transaction data is not compliant data, the invoked supervision instance may determine that the compliance status flag value is not the target value. Finally, when the compliance status flag value corresponding to the supervision result is the target value, the invoked supervision instance may associatively store the target string and the target transaction data in the status database, and then only save the transaction data initially determined to have no leakage risk by the supervision contract in the status database, thereby avoiding the leakage of transaction data.

[0135] Therefore, in the embodiments of the present invention, penetrative and imperceptible supervision can be performed on the transaction data on the chain. The user only needs to invoke the supervision encapsulation interface, the transaction data does not need to be signed, and the user is unaware of the supervision behavior.

[0136] In some embodiments, after determining the compliance status flag value corresponding to the supervision result, the data processing method may further include:

[0137] When the compliance status flag value corresponding to the supervision result is not the target value, feedback a second prompt message to the data storage node; wherein, the second prompt message is used to prompt that the detection of the target transaction data fails.

[0138] Thus, when the invoked supervision instance determines that the compliance status flag value corresponding to the supervision result is not the target value, it can determine that the target transaction data is non-compliant, and then prompt the user through the second prompt message that the target transaction data to be stored is non-compliant, so as to further avoid the leakage of transaction data.

[0139] Wherein, the second prompt message may include information for representing "data violation, unable to be uploaded to the chain" to prompt the user that the target transaction data to be stored is non-compliant.

[0140] In some embodiments, after determining the compliance status flag value corresponding to the supervision result, the data processing method may further include:

[0141] When the compliance status flag value corresponding to the supervision result is not the target value, reject associatively storing the target string and the target transaction data in the status database.

[0142] Thus, when the call supervision instance determines that the detection result is the detection of the target data, it may not upload the target transaction data to the status database to further avoid the leakage of transaction data.
