Embodiments of the invention

The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of this application.

The data processing method based on the smart contract provided in the embodiment of the present application (for convenience of description, the method provided in the embodiment of the present application may be referred to as the method). The method provided in the embodiments of the present application can be applied to any blockchain node server, and can also be applied to other node servers or related network nodes, and is not limited here. Taking a certain blockchain node server as an example, the method provided by the embodiment of the present application will be described with reference to FIGS. 1 to 4.

Refer to Fig. 1, which is a schematic flowchart of a data processing method based on a smart contract provided by an embodiment of the present application. The method provided in the embodiment of the present application may include the following steps 101-105.

101. Receive service data to be processed sent by the data sender.

In some feasible implementations, since the smart contract verifies data or executes the content of the contract to process the data based on the agreement reached by the contract participants, when receiving the pending business data sent by the data sender, It is necessary to verify whether the data sender is a contract participant, that is to say, it is necessary to verify whether the pending business data sent by the data sender meets the trigger condition of invoking the smart contract, so as to call the smart contract to perform business data processing on the received pending business data . In specific implementation, a blockchain node can deploy designated data content that meets the conditions for invoking the smart contract in any storage area connected to it. When the data sender sends the service data to be processed, the data identifier corresponding to the specified data content can be added to the service data to be processed. When receiving the service data to be processed from the data sender, it can be determined whether the specified data content in any of the above storage areas contains the data identifier of the service data to be processed. If it contains the data identifier of the service data to be processed, the data is determined The sender is the contract participant. At this time, the smart contract can be called and executed to perform business data processing on the above-mentioned pending business data. Among them, the above-mentioned data senders include but are not limited to transaction initiators, identity verification initiators, and product supply chain providers, etc., which are not limited here. It should be noted that the above specified data content and the above data identifier are only used to determine whether the business data to be processed meets the conditions for invoking the smart contract. The specific data expression form can be one or more combinations of numbers, letters, and symbols. There is no restriction. At the same time, any of the above-mentioned storage areas includes, but is not limited to, storage devices in the blockchain network, or cloud storage and hard disks connected to blockchain nodes, and there is no restriction here.

102. Determine, based on the first smart contract, whether the service data to be processed includes the data to be intercepted.

In some feasible implementations, since the general smart contract exists in the form of computer-readable code, and the smart contract itself does not have the ability to intercept data, before determining whether the above-mentioned service data to be processed includes the above-mentioned data to be intercepted, The first smart contract with the ability to intercept data needs to be generated. In specific implementation, the second smart contract for processing the above-mentioned service data to be processed may be determined according to the service data to be processed sent by the data sender, and the contract code of the above-mentioned second smart contract may be obtained. At the same time, after the data to be intercepted is determined based on the specific application scenarios when processing the business data sent by the data sender and the data sender, the interception code is generated according to the data to be intercepted, and generated in combination with the contract code of the second smart contract. The first smart contract mentioned above. Wherein, the above-mentioned first smart contract has the same business data processing capabilities as the above-mentioned second smart contract, and at the same time, it can intercept the pending business data that meets the interception conditions.

In some feasible implementation manners, after receiving the to-be-processed business data sent by the data sender, and the to-be-processed business data can call the first smart contract, the to-be-processed data can be verified before executing the first smart contract. Whether the service data includes the above-mentioned data to be intercepted, so as to determine whether to intercept the above-mentioned service data to be processed based on the above-mentioned first smart contract. In specific implementation, since the first smart contract contains the data to be intercepted, the business data to be processed can be matched with the data to be intercepted to determine whether the business data to be processed includes the data to be intercepted. However, due to the different data processing methods used by the data sender to process the business data to be processed, the business data to be processed will not be sent by the data sender in a fixed data format. Therefore, for the two different formats of data, it is impossible to determine Whether data in one format contains data in another format. Based on the foregoing reasons, before matching the foregoing business data to be processed and the foregoing data to be intercepted, the data format of the foregoing data to be intercepted and the data format of the foregoing business data to be processed may be acquired first. At this time, it can be determined whether the data format of the data to be intercepted is consistent with the data format of the business data to be processed. If the two are consistent, the data to be intercepted can be directly matched with the business to be processed, and when the business to be processed is When there is a data segment consistent with the data to be intercepted, it can be determined that the business data to be processed includes the data to be intercepted. For example, when the data format of the above-mentioned service data to be processed and the above-mentioned data to be intercepted are both binary data, and the partial data of the above-mentioned service data to be processed is "000101010001001011100", and the above-mentioned data to be intercepted is "0111", then the above-mentioned pending data is The business data contains the data segment "0111" that is consistent with the data to be intercepted, so it can be determined that the business data to be processed contains the data to be intercepted. If the data format of the data to be intercepted is inconsistent with the data format of the business data to be processed, the data format of the data to be intercepted and/or the data format of the business data to be processed can be modified to make the data format of the data to be intercepted and The data format of the business data to be processed is the same. For example, when the data to be intercepted is binary data and the amateur data to be processed is decimal data, the data to be intercepted can be processed to modify the data to be intercepted into decimal data. It is also possible to perform data processing on the service data to be processed to modify the service data to be processed into binary data. It is also possible to perform data processing on the service data to be processed and the data to be intercepted at the same time to modify the service data to be processed and the data to be intercepted into any hexadecimal data except binary and decimal. The specific implementation is not done here. limit.

In some feasible implementation manners, in the process of determining whether the to-be-intercepted data is included in the to-be-processed business data based on the data segment that is consistent with the to-be-intercepted data, the to-be-processed data cannot be determined. Whether the business data contains data that has the same semantics as the above-mentioned data to be intercepted but has a different data presentation form. For example, when the data to be intercepted is data representing "paper invoices", that is to say, the first smart contract can be used to intercept the business data to be processed containing "paper invoices", if the business data to be processed contains "non-electronic "Invoice", the above-mentioned first smart contract will determine that the above-mentioned pending business data does not contain the to-be-intercepted data, which in turn leads to the intelligent interception of pending business data containing "paper invoices" based on the above-mentioned first smart contract, and cannot be intercepted. "Non-electronic invoice" pending business data. In order to improve the above situation, after the data to be intercepted is determined, at least one target data that is semantically consistent with the data to be intercepted and whose data expression format is different from the data to be intercepted can be determined from the preset database. Among them, the data in the above-mentioned preset database can be common intercepted data obtained from the Internet, big data platforms or other storage spaces, or can be intercepted data pre-designated by the data sender, data receiver, and smart contract manager , The specific source is not restricted. In the process of determining whether the service data to be processed includes the data to be intercepted, it can be determined whether there is a data segment consistent with any one of the at least one target data in the service data to be processed, so as to expand the first intelligence. The scope of the contract's identification of the above-mentioned pending business data. When there is a data segment consistent with any one of the at least one target data in the above-mentioned service data to be processed, it can be determined that the above-mentioned service data to be processed includes the above-mentioned data to be intercepted. Wherein, the data format of any data in the preset database is consistent with the data format of the data to be intercepted, and in the process of matching the business data to be processed with the at least one target data, the data format of the business data to be processed is The data format needs to be consistent with the data format of the data to be intercepted above, and will not be repeated here. It should be noted that if the service data to be processed sent by the data sender is data that has been processed through encryption, compression, etc., it is necessary to decrypt and decompress the service data to be processed to obtain the complete service data to be processed. , And then obtain the data format of the service data to be processed, which will not be repeated here.

103. If the service data to be processed includes the data to be intercepted, the service data to be processed is intercepted based on the first smart contract. If the service data to be processed does not include the data to be intercepted, the data to be intercepted is processed based on the first smart contract. The business data to be processed is processed for business data.

In some feasible implementation manners, if the service data to be processed does not include the data to be intercepted, business data processing is performed on the service data to be processed based on the first smart contract. For example, for the supply chain provider, the company, institution, product and other information in the data provided by the supply chain provider can be verified based on the corresponding smart contract, so that the supply chain data remains accurate and effective at every link. For another example, for the transaction initiator, the transaction request can be verified based on the corresponding smart contract, which further simplifies the transaction process and reduces data errors.

In some feasible implementation manners, if the service data to be processed includes the data to be intercepted, the service data to be processed can be intercepted at this time. In specific implementation, the aforementioned pending business data can be deleted to prevent the aforementioned first smart contract from performing business data processing on the aforementioned pending business data, or while the aforementioned pending business data is deleted, a deletion notification can be generated and based on the aforementioned pending data. Send the deletion notice to the data sender, so that the data sender modifies the pending service data and resends the revised pending service information after receiving the deletion notice. For details, please refer to FIG. 2, which is a schematic flowchart of a method for intercepting service data to be processed based on a smart contract according to an embodiment of the present application. The method for intercepting service data to be processed based on a smart contract provided in the embodiment of the present application may include the following steps 201-203.

201. Determine the number of data segments consistent with the data to be intercepted in the business data to be processed, and determine the risk level of the business data to be processed based on the number of data segments.

In some feasible implementation manners, when it is determined that the business data to be processed has a data segment consistent with the data to be intercepted, or when it is determined that the business data to be processed has data that is consistent with any one of the foregoing at least one target data During segment time, the number of data segments between the to-be-processed business data and the data to be intercepted or any target data can be determined, and then the risk level of the to-be-processed business data can be determined according to the number of data segments. Among them, the larger the number of data segments, the higher the risk of the business data to be processed, and the smaller the number of data segments, the lower the risk of the business data to be processed. Therefore, after receiving the alarm information, the data sender can take different influence measures according to the risk level of the service data to be processed. It should be particularly noted that when the above-mentioned data to be intercepted is related bad information such as pornography, Trojan horses, and viruses, the above-mentioned risk level may reflect the severity of the security risk of the data sender itself and the service data to be processed. When the above-mentioned data to be intercepted is information that is not applicable to the current application scenario (such as accounts, invoices, etc.), the above-mentioned risk level can reflect the degree of data management norms of the data sender and the data to be processed, which can be combined with specific The application scenarios and the types of data to be intercepted determine different response measures.

202. Determine an alarm mode and alarm information corresponding to the service data to be processed based on the risk level.

In some feasible implementation manners, after intercepting the above-mentioned service data to be processed based on the above-mentioned first smart contract, alarm information may be generated based on the intercepted service data to be processed and sent to the data sender. Among them, the alarm information generated based on the intercepted service data to be processed may include the data to be intercepted, so that the data sender can respond to the alarm to be intercepted after receiving the alarm information.

203. Send the alarm information and the service data to be processed to the data sender based on the alarm mode.

In some feasible implementation manners, after the risk level of the service data to be processed is determined, different alarming methods can be determined according to different risk levels, so that different alarming methods are used to send the alarm information to the data sender. For example, when the risk level of the aforementioned business data to be processed is a high risk level, a faster warning method (instant alarm, telephone notification, etc.) can be used to send the alarm information to the data sender so that the data sender is the first Time to take countermeasures. When the risk level of the above-mentioned business data to be processed is low risk level, the alarm method (email, SMS, etc.) with a slower alarm speed can be used to send the alarm information to the data sender so that the data sender can take countermeasures according to the actual situation. The implementation of the specific alarm method is not limited here.

In the embodiment of the present application, the sending method of the alarm information can be determined based on the risk level of the business data to be processed, so that the alarm information corresponding to different risk levels has different alarm methods, making the alarm of the business risk data more targeted and flexible , High applicability.

104. Determine whether the processed business data contains the aforementioned data to be intercepted.

In some feasible implementation manners, since the process of executing the smart contract is a process of data verification and processing, data changes in the process of performing business data processing on the business data to be processed based on the first smart contract cause The processed business data may contain the aforementioned data to be intercepted. That is to say, after performing business data processing on the business data to be processed through the first smart contract, business data to be processed that does not originally need to be intercepted needs to be intercepted because the data to be intercepted is generated. Therefore, after the processed business data is obtained, it is necessary to determine again whether the processed business data includes the data to be intercepted. The specific determination method is as shown in step 102, which will not be repeated here.

In some feasible implementation manners, after the processed business data is obtained, the data type of the processed business data can also be obtained, and the data processing tool that processes the corresponding data type is used to determine the processed business data according to different data types. Does your business data contain the aforementioned data to be intercepted? For example, when the processed business data is image data, an image processing tool can be used to determine whether the image data contains the data to be intercepted. For another example, when the processed service data is audio data, an audio processing tool can be used to determine whether the audio data contains the data to be intercepted. Optionally, when the above-mentioned processed service data includes multiple types of data (for example, both image data and audio data), multiple data processing tools may be used at the same time to determine whether the processed service data contains data to be intercepted . In addition, by calling a third-party data processing platform with data analysis, identification and interception capabilities, when the processed business data is generated, the above-mentioned first smart contract can directly call the relevant interface of the third-party processing platform to enable third-party data processing The platform can receive and determine whether the processed business data contains the aforementioned data to be intercepted, and the specific implementation method is not limited here.

105. If the above-mentioned processed business data contains the above-mentioned data to be intercepted, intercept the above-mentioned processed business data, and if the above-mentioned processed business data does not contain the above-mentioned data to be intercepted, then send the above-mentioned processed business data to the data receiver square.

In some feasible implementation manners, when the processed business data includes the intercepted data, the processed business data can be intercepted. The specific interception method is as shown in step 103, which will not be repeated here. Optionally, after the service data to be processed is processed based on the first smart contract, the processed service data needs to be sent to the data receiver. Among them, the above-mentioned data receivers include but are not limited to transaction accounting platforms, product distribution systems, and data distribution platforms, etc., which are not limited here. When the above-mentioned processed business data is intercepted, in order to avoid the data receiver’s failure to receive the processed business data and cause the data receiver to generate alarms and other negative effects, the above-mentioned processed business data can be intercepted and sent to the data receiver at the same time. For sending alarm information, refer to step 103 for a specific implementation manner. Interception notification information may also be generated to inform the data receiver that the above-mentioned processed business data has been intercepted, so as to avoid unnecessary losses.

In the embodiment of the application, in the embodiment of the application, the smart contract with data interception function is generated based on the data to be intercepted, so that when the service to be processed is processed based on the smart contract, the data to be intercepted can be intercepted. Processing business data improves the data processing capabilities of smart contracts. In addition, by intercepting the processed business data, the ability to intercept data based on smart contracts can be further improved, with higher adaptability. At the same time, while realizing the interception of the business information to be processed, it can provide the data sender and data receiver with corresponding alarm methods. Not only can the data sender and data receiver take timely response measures, but also further eliminate the data Security risks.
