[0049] 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.

[0050] It should be understood that the "embodiments of the present application" or "the aforementioned embodiments" mentioned throughout the specification mean that specific features, structures or characteristics related to the embodiments are included in at least one embodiment of the present application. Therefore, "in the embodiments of the present application" or "in the aforementioned embodiments" appearing throughout the specification may not necessarily refer to the same embodiment. In addition, these specific features, structures or characteristics may be combined in one or more embodiments in any suitable manner. In the various embodiments of the present application, the size of the sequence numbers of the above-mentioned processes does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application. The above-mentioned sequence numbers of the embodiments of the present application are for description only and do not represent the advantages and disadvantages of the embodiments.

[0051] Unless otherwise specified, the electronic device performs any step in the embodiments of the present application, and the processor of the electronic device may perform the step. It is also worth noting that the embodiments of the present application do not limit the order in which the electronic device performs the following steps. In addition, the methods used to process data in different embodiments may be the same method or different methods. It should also be noted that any step in the embodiments of the present application can be independently executed by the electronic device, that is, when the electronic device executes any step in the following embodiments, it may not rely on the execution of other steps.

[0052] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0053] The embodiment of the present application provides a production data transmission method based on a data request. The method can be applied to an electronic device. The electronic device may refer to a device where a data responder is located. Figure 1 As shown, the method includes the following steps 101 to 104:

[0054] Step 101: In response to a data request, a virtual request time is determined based on a sending time of a data requester and a first preset time.

[0055] Data requests in production lines mainly refer to requests involved in the real-time collection, transmission, processing and analysis of various data on production lines during industrial production. Data in production lines may include but are not limited to: the operating status of production lines, data generated during production, process parameters, manufacturing parameters, etc.

[0056] The data requester refers to the party that initiates the data request. The sending time refers to the time when the data requester sends the data request. The first preset time refers to a preset time; for example, the first preset time can be half an hour. The first preset time is obtained by the technical personnel of this application through a large number of tests, which can well implement the production data transmission method based on data request proposed in this application, and greatly improve the usability of this application.

[0057] The virtual request time refers to the time virtualized based on the sending time of the data requester. In a feasible implementation, the sending time of the data requester can be encrypted to obtain the virtual time, or a preset time (or other mask used to disguise the sending time) can be added to the sending time of the data requester to obtain the virtual time.

[0058] The purpose of setting the virtual request time is to protect the time when the actual data requester sends the data request (sending time). During the data transmission process, the virtual request time is transmitted instead of directly transmitting the actual sending time. This can prevent other organizations from capturing the sending time of the data requester and maliciously changing the system time or using a virtual machine to set the time, thereby improving the security and reliability of production line data requests.

[0059] In some implementations, a specific implementation of step 101 may be: determining the sum of the sending time of the data requester and the first preset time to obtain the virtual request time.

[0060] Step 102: Determine a key for the data request based on the basic information of the data requester and the virtual request time.

[0061] The basic information of the data requester can reflect the data that the data requester wants to access and the access method.

[0062] The basic information of the data requester refers to the basic information of the individual, team or system that initiates the data request in the production line. This information helps to ensure the accuracy, security and effectiveness of the data request. The basic information of the data requester may include, but is not limited to: the name of the data requester (individual name or team / department name), the purpose of the request, the specific reason or purpose of the data request, how the data will be used and the expected results, the type and scope of the data, the data format, the method and frequency of data transmission (real-time, batch, on-demand, etc.), the contact information of the requester, and other information.

[0063] In some implementations, step 102 may be specifically implemented by determining the key based on the target information and the virtual request time in the basic information of the data requester. Since the amount of information in the basic information is large and the attacker would not expect that the key is determined by the target information in the basic information, inconspicuous information may be selected from the basic information and the key may be determined using the information and the virtual request time.

[0064] In some implementations, step 102 may be specifically implemented as follows: determining the private data based on the basic information of the data requester; and determining the key based on the private data and the virtual request time.

[0065] It should be noted that the key is determined based on the privacy data and virtual request time to ensure that the privacy data and virtual request time cannot be captured or even arbitrarily modified by other organizations. The key is then transmitted during transmission, and the privacy data and virtual request time are obtained by decrypting the key when used. In this way, the system time can be prevented from being maliciously changed or the time is set using a virtual machine during data transmission, thereby improving the security and reliability of production line data requests.

[0066] Step 103: Determine whether the data request is abnormal based on the virtual request time and the current time in the key.

[0067] The purpose of determining whether there is an abnormality in the data request based on the virtual request time and the current time in the key is to determine whether the current data has been maliciously tampered with, so as to increase the security and reliability of production data during transmission.

[0068] In some implementations, step 103 may be specifically implemented by determining whether there is an abnormality in the data request based on the time interval between the virtual request time and the current time.

[0069] It should be noted that the larger the time interval between the virtual request time and the current time, the more likely the data has been maliciously tampered with or someone has used the virtual machine to set the time, and the time interval does not meet the requirements and the transmission operation cannot be performed.

[0070] Step 104: If there is no abnormality in the data request, the data that the data requester wants to access is sent to the data requester.

[0071] In the embodiment of the present application, the sending time of the data requester can be protected by the first preset time, and then the data can be transmitted with the virtual request time; the key of the data request is determined based on the basic information of the data requester and the virtual request time, and the virtual request time can be saved in the key. Then, when transmitting, the key is transmitted instead of the actual information, which can prevent the problem of maliciously changing the system time or using the virtual machine to set the time during the data transmission process, so as to improve the security and reliability of the production line data request. Based on the virtual request time and the current time in the key, it is determined whether the data request is abnormal, and it can be determined whether the current data has been maliciously tampered with, further improving the security and reliability of the production data during the transmission process. At the same time, even if the identity authority of the requester is diverse, it can greatly increase the security of the data transmission process, and maximize the intelligence, security and reliability of the production line data request.

[0072] Based on the above embodiments, the present application embodiment provides a production data transmission method based on data request, referring to Figure 2 As shown, the method comprises the following steps:

[0073] Step 201: In response to a data request, determine whether the data request is an operable request based on a preset data request operation table.

[0074] The data request operation table is pre-set and includes multiple operable data requests.

[0075] For example, if only requests for reading data can be processed currently, but requests for modifying data cannot be processed; then, various requests for reading data are stored in the data request operation table. In this way, after receiving a data request, the data request is matched with the requests in the data request operation table. If the match is successful, the data request is determined to be an operable request. If the match fails, it is not processed.

[0076] Step 202: If the data request is an operable request, basic information of the data requester and the sending time of the data requester are obtained.

[0077] In some implementations, step 202 may be specifically implemented as follows: if the data request carries basic information and sending time of the data requester, the basic information and sending time of the data requester may be directly obtained from the data request.

[0078] In some implementations, the specific implementation of step 202 may also be: in response to the data request, a basic information acquisition request is sent to the data requester to obtain the basic information of the data requester. Since the operation request carries timestamp information, the timestamp information in the operation request may be directly used as the sending time. The data transmission between the data requester and the data responder is encrypted transmission.

[0079] Step 203: Determine a virtual request time based on the sending time of the data requester and the first preset time.

[0080] Step 204: Send the basic information of the data requester to the privacy node for processing to obtain private data.

[0081] The privacy data may reflect the identity information of the data requester.

[0082] The privacy node is used to obtain the corresponding private data and registration data based on the basic information of the data requester, and can also be used to encrypt the private data and virtual request time to obtain the key.

[0083] In some implementations, step 204 may be specifically implemented by sending the basic information of the data requester to a privacy node for registration, and the privacy node matches the basic information of the data requester with a pre-stored correspondence between multiple data requesters and corresponding privacy data to obtain the corresponding privacy data.

[0084] Step 205: Encrypt the private data and the virtual request time to obtain the key.

[0085] The basic information of the data requester can reflect the data that the data requester wants to access and the access method.

[0086] In some implementations, an encryption algorithm may be used to encrypt the private data and the virtual request time to obtain a key. The encryption algorithm may be: a symmetric encryption algorithm, a secure hash algorithm, a stream encryption algorithm, or a hybrid encryption algorithm.

[0087] Step 206: Determine whether the data request is abnormal based on the virtual request time and the current time in the key.

[0088] In some implementations, step 206 may be specifically implemented by determining whether there is an abnormality in the data request based on a matching relationship between a time interval between the virtual request time and the current time and a preset time threshold.

[0089] In some embodiments, the specific implementation method of step 206 may be: decrypting the key to obtain the virtual request time; determining the time interval between the virtual request time and the current time; if the time interval meets the time threshold, determining that there is no abnormality in the data request; if the time interval does not meet the time threshold, determining that there is an abnormality in the data request.

[0090] The time interval satisfies the time threshold, which means that the time interval is less than or equal to the time threshold. The time interval does not satisfy the time threshold, which means that the time interval is greater than the time threshold.

[0091] In a feasible implementation, the key is decrypted using a decryption algorithm corresponding to the encryption algorithm to obtain the virtual request time.

[0092] Step 207: If there is no abnormality in the data request, the data that the data requester wants to access is sent to the data requester.

[0093] In some implementations, step 207 may be specifically implemented as follows: if the time interval is less than or equal to the time threshold, the data that the data requester wants to access is sent to the data requester.

[0094] In some embodiments, the specific implementation method of "sending the data that the data requester wants to access to the data requester" in step 207 can be: sending the private data to the data right holder so that the data right holder initiates a data transmission channel based on the private data; and sending the data that the data requester wants to access to the data requester through the data transmission channel.

[0095] The data rights holder is used to authorize data transmission, that is, to open the data transmission channel.

[0096] In some embodiments, the production data transmission method based on data request may further include: if there is an abnormality in the data request, the private data is not sent to the data right holder for data transmission.

[0097] In some implementations, if the time interval is greater than the time threshold, the private data is not sent to the data rights holder for data transmission.

[0098] Based on the above embodiment, in other embodiments of the present application, the production data transmission method based on data request may also include the following steps 208 to 209:

[0099] Step 208: Send the basic information of the data requester to the privacy node for processing to obtain registration data.

[0100] In some implementations, step 206 may be implemented by sending the basic information of the data requester to the privacy node, and the privacy node may extract registration data from the basic information of the data requester. The registration data may include, but is not limited to, the data requester's data request record, credit score, and authority.

[0101] In some implementations, the specific implementation method of step 206 can also be: sending the basic information of the data requester to the privacy node for registration, and the privacy node obtains the data requester's data request record, credit score, authority and other information from the database based on the basic information of the data requester to obtain the registration data.

[0102] Step 209: Determine whether the data request satisfies processing authority based on the registration data and the key.

[0103] In some implementations, step 209 may be specifically implemented as follows: determining whether the data request satisfies the operation authority based on the registration data; determining whether the data request satisfies the transmission authority based on the key; and processing authority includes operation authority and transmission authority.

[0104] In some implementations, step 209 may be implemented by steps 2091 to 2094 as follows:

[0105] Step 2091: Determine whether the data request satisfies the operation authority based on the request record, credit score, and authority in the registration data.

[0106] The authority may include but is not limited to: production worker, supervisor, and supervisor. The operation authority may be determined based on at least one of the request frequency, credit score, and authority. For example, the operation authority may be that the request frequency does not exceed 5 times per hour, the credit score is greater than 7, and the authority is a supervisor. The request frequency can be obtained based on the request record.

[0107] Step 2092: Based on the private data in the key, determine whether the data request satisfies the transmission authority.

[0108] In some implementations, step 2092 may be specifically implemented by: determining whether the representation data request satisfies the transmission authority based on a matching relationship between the privacy data and a plurality of preset authority data.

[0109] In some embodiments, the specific implementation method of step 2092 may be: sending the key to a matching node so that the matching node obtains the privacy data based on the key, and based on the matching relationship between the privacy data and a plurality of preset permission data, determines a matching result representing whether the data request satisfies the transmission permission; and receiving the matching result sent by the matching node.

[0110] The matching node can be used to determine whether the data request satisfies the transmission permission.

[0111] Step 2093: If the data request satisfies the operation authority and the transmission authority, determine that the data request satisfies the processing authority.

[0112] Step 2094: If the data request does not satisfy the operation authority and / or the data request does not satisfy the transmission authority, determine that the data request does not satisfy the operation authority.

[0113] In this way, step 207 may be: if the data request satisfies the processing authority and there is no abnormality in the data request, the data that the data requester wants to access is sent to the data requester.

[0114] It should be noted that, for the description of the same steps and the same contents in this embodiment as those in other embodiments, reference can be made to the description in other embodiments and will not be repeated here.

[0115] It should be noted that, in the existing blockchain privacy protection method, although the request is fair and cannot be tampered with, when it comes to privacy requests, each request directly outputs the requester information, and it is impossible to guarantee that the information of the requesting participants will not be leaked. The risk of privacy leakage is high, and there is a problem of maliciously changing the system time or using a virtual machine to set the time, which leads to a great security risk in the request process. After obtaining the data request, the present application does not directly transmit the privacy data and sending time of the data requester, but obtains the privacy data by sending the basic information of the data requester to the privacy node, and saves the privacy data and the virtual request time in the key. In this way, the risk of privacy leakage can be minimized to the greatest extent, and the privacy data and the virtual request time can be prevented from being modified at will. It solves the problem of maliciously changing the system time or using a virtual machine to set the time during the data transmission process in the existing scheme, greatly increases the security of the data transmission process, and maximizes the intelligence, security and reliability of the production line data request.

[0116] In the embodiment of the present application, the sending time of the data requester can be protected by the first preset time, and then the data can be transmitted with the virtual request time; the key of the data request is determined based on the basic information of the data requester and the virtual request time, and the virtual request time can be saved in the key. Then, when transmitting, the key is transmitted instead of the actual information, which can prevent the problem of maliciously changing the system time or using the virtual machine to set the time during the data transmission process, so as to improve the security and reliability of the production line data request. Based on the virtual request time and the current time in the key, it is determined whether the data request is abnormal, and it can be determined whether the current data has been maliciously tampered with, further improving the security and reliability of the production data during the transmission process. At the same time, even if the identity authority of the requester is diverse, it can greatly increase the security of the data transmission process, and maximize the intelligence, security and reliability of the production line data request.

[0117] The following describes the application of the production data transmission method based on data request provided in an embodiment of the present application in a practical scenario.

[0118] In traditional blockchain networks, all institutions participating in data requests (blockchain nodes) communicate with other institutions using a centralized network. However, during the communication process, failures and restriction policies such as gateways, proxies, and central servers may cause communication interruptions between institutions or increase additional costs in the communication process. In the traditional model, data is owned by each institution, and modification operations are easy to perform, but it is difficult to verify the authenticity and validity of data requested between institutions.

[0119] In the production line, because the production plan of the production line, the information of the products produced and other data involve a lot of confidentiality and privacy, it is not feasible to fully disclose the data, and the protection of privacy information is particularly important. However, the request privacy protection method of the above blockchain still has the following shortcomings: although the request is fair and cannot be tampered with, the design of request authentication does require that once a privacy request is involved, each request directly outputs the requester information, and it cannot guarantee that the information of the requesting participants will not be leaked. The risk of privacy leakage is high, and the identity permissions of the sender and the requester are diverse, which may cause difficulties in data supervision, and there is a problem of maliciously changing the system time or using a virtual machine to set the time, which leads to great security risks in the request process.

[0120] To this end, an embodiment of the present application provides a production data transmission method based on a data request, including:

[0121] S100. When a data request is received, the data requester information and the request time node data are obtained, and virtual request time node data is calculated according to the request time node data and the preset time interval data.

[0122] Here, the data requester information may refer to the basic information of the data requester. The request time node data may refer to the sending time of the data requester. The preset time interval data may refer to the first preset time. The virtual request time node data may refer to the virtual request time.

[0123] It should be noted that, before step S100, the following may also be included: presetting a time threshold and preset time interval data in the control module.

[0124] The time threshold and preset time interval data can be set according to actual business needs.

[0125] In a feasible implementation method, the preset time interval data can be set to half an hour, and the time threshold can be set to 5 seconds. The above settings are obtained by the technical personnel of this application through a large number of tests, and can well implement the production data transmission method based on data request proposed in the embodiment of this application, thereby greatly improving the usability of this application.

[0126] In some embodiments, the specific implementation of "calculating the virtual request time node data according to the request time node data and the preset time interval data" in S100 can be: calculating the sum of the request time node data and the preset time interval data to obtain the virtual request time node data. The virtual request time node data in this application is later than the request time node data.

[0127] Specifically, the data request-based production data transmission method provided in the embodiment of the present application also includes: before executing step S100, establishing a data request operation table; when executing step S100, when an operation request is received, judging whether the operation request is a data request according to the data request operation table; if so, obtaining data requester information and request time node data, and calculating virtual request time node data according to the request time node data and the preset time interval data; if not, not executing the operation.

[0128] S200: Input the data requester information into the privacy node for registration, obtain registration data and privacy data, and encrypt the privacy data and virtual request time node data to obtain a key.

[0129] Specifically, the production data transmission method based on data request provided in the embodiment of the present application also includes:

[0130] Before executing step S200, a privacy node is established in the blockchain network.

[0131] Specifically, the production line production data exchange monitoring method based on data collection provided in an embodiment of the present application also includes: when executing step S200, the privacy data is stored in the privacy node, the privacy data and the virtual request time node data are encrypted to obtain a key, and the registration data and the key are sent back to the blockchain network.

[0132] S300: Determine whether the registration data meets the data request operation authority requirements, if so, execute step S400; otherwise, do not execute the operation.

[0133] Specifically, the registration data includes the data request record, score and authority of the data requester; when executing step S300, it is determined whether the data request record, score and authority in the registration data meet the data request operation authority requirements. If so, step S400 is executed; otherwise, no operation is performed.

[0134] S400: Match the data transmission operation of the data requester's private data through the key to determine whether the match is successful; if so, obtain the virtual request time node data and the current time node data through the key, calculate the time interval data between the virtual request time node data and the current time node data, determine whether the time interval data is less than or equal to the time threshold, and determine whether to send the private data to the data right holder for data transmission operation based on the judgment result.

[0135] Specifically, the embodiment of the present application determines whether the time interval data is less than or equal to the time threshold, and determines whether to send the private data to the data right holder for data transmission operation according to the determination result, including:

[0136] If the time interval data is less than or equal to the time threshold, the private data is sent to the data rights holder for data transmission.
