Mode for Carrying Out the Invention

[0050] Hereinafter, the present disclosure will be described in more detail with reference to the drawings and examples.

[0051] In related technologies, data circulation and sharing realized through a big data trading center cannot meet the needs of data demanders. Specifically, there are defects in meeting the privacy needs of users, mediating transactions that match the computing needs of data demanders, and ensuring the legality and / or regulatory compliance of data packets. For example, data API products cannot meet the user privacy needs of data demanders, data packet services cannot guarantee the non-disclosure of user privacy, and furthermore, for example, a big data trading center cannot select data providers based on the computing needs of data demanders and promote joint computing between data demanders and data providers.

[0052] Based on this, in various embodiments of the present disclosure, a data requester (i.e., the first node) transmits a computing requirement (i.e., the first information) to the first platform, whereby the first platform can match a data provider (i.e., the second node) based on the computing requirement. In other words, the first platform transmits the computing requirement to a data provider that matches the computing requirement, whereby the data provider can perform a calculation based on the requirement of the data requester, and further, the data requester can obtain a calculation result that matches its own requirement.

[0053] Also, in various embodiments of the present disclosure, based on the computing requirement of the data requester, in a scenario where the user privacy requirement of the data requester is protected and the data of the data provider does not appear (i.e., the data does not leave the domain of the data provider), it can be realized that the data of the data provider accesses the first platform.

[0054] Thirdly, in various embodiments of the present disclosure, the first platform can verify the availability of the data of the data provider, whereby it can guarantee data packet legality and / or compliance with regulations, and can further guarantee data security.

[0055] Embodiments of the present disclosure provide a communication method applied to a first node. The communication method includes a step of transmitting first information to a first platform, where the first information is used for joint calculation between the first node and at least one second node or calculation of at least one second node, and the first information includes related information required for the calculation.

[0056] In actual applications, the first node may also be referred to as a data requester node or a data requirement node (which can be expressed as Data Requirement Node in English and abbreviated as DRN). Embodiments of the present disclosure do not limit the name of the first node as long as its function is realized.

[0057] In actual applications, the second node may also be referred to as a data provider node, a data providing node, or a data service node (which can be expressed in English as Data Service Node and abbreviated as DSN). In the embodiments of the present disclosure, as long as its function is realized, the name of the second node is not limited.

[0058] In actual applications, the first platform may also be referred to as a data sharing service platform (DSSP: Data Sharing Service Platform) or a data sharing platform (DSP: Data Sharing Platform). In the embodiments of the present disclosure, as long as its function is realized, the name of the first platform is not limited.

[0059] In actual applications, the collaborative calculation between the first node and at least one second node can be understood as performing federated learning, that is, joint model training. Specifically, it may include horizontal federated learning, vertical federated learning, etc. The present disclosure does not limit the type of federated learning.

[0060] In actual applications, when the first information is used for the calculation of one second node, the calculation can include model training, target query (for example, blacklist query), operation of a specified formula, etc. When the first information is used for the calculation of multiple second nodes, the calculation refers to the collaborative calculation of multiple second nodes, that is, federated learning.

[0061] In actual applications, it is understandable that when the calculation corresponding to the first information requires the use of the data of the data requester (that is, the data stored in the first node), the first information is used for the collaborative calculation between the first node and at least one second node. When the calculation corresponding to the first information does not require the use of the data of the data requester, the first information is used for the calculation of at least one second node.

[0062] In one embodiment, the first information includes algorithm information required for the calculation, identifiers of the at least one second node (e.g., ID, i.e., abbreviation of Identifier), and may include at least one of the identifiers of the first node.

[0063] Here, the algorithm information required for the calculation may include information such as the name, identifier, and algorithm usage order of the calculation engine and algorithm agreed upon by the data requester and the data provider. Embodiments of the present disclosure do not limit the specific content of the algorithm information required for the calculation as long as its function is realized.

[0064] In actual applications, the first information may include contents such as the data type required for the calculation, data set (e.g., the name of the fields that need to be included in the data), etc., and specifically can be set according to the needs of the data requester.

[0065] In actual applications, the data requester and the data provider can reach a cooperation intention offline to determine the first information and store the first information in the first node local database. In other words, the first node can obtain the first information locally.

[0066] In actual applications, the data requester and the data provider can directly send the first information from the first node to the first platform without prior offline negotiation. After receiving the first information sent by the first node, the first platform can send the first information to each second node based on the identifier of the second node. After receiving the first information sent by the first platform, each second node can review the first information. For example, the first node can be authenticated using a predetermined second policy, and if the authentication is passed, the calculation corresponding to the first information is performed.

[0067] In actual application, the first node can send the first information to the first platform according to a fourth request. The fourth request is used to request the execution of calculations corresponding to the first information. In other words, the fourth request includes at least the first information. After receiving the fourth request, the first platform matches (i.e., selects) an appropriate second node for the first node based on the first information, and then can send the fourth request to each matched second node. As a result, the second node can execute corresponding calculations based on the first information. Here, the fourth request may also be referred to as a data usage request, a data calculation request, a data application request, etc. Embodiments of the present disclosure do not limit the name and specific transmission timing of the fourth request as long as its function is realized.

[0068] In actual applications, the calculation corresponding to the first information can be understood as one application (which may also be referred to as a project, task, job, event, etc., and the embodiments of the present disclosure do not limit its name), and the first node, the first platform, and each second node need to generate a data application, that is, store information related to the application (for example, the first information). Exemplarily, after receiving the first information sent by the first node, the first platform can generate a data application based on the first information, that is, locally generate and store information related to the calculation corresponding to the first information, such as information about the collaborators participating in the calculation (that is, the first node and at least one second node, or at least one second node), the content of cooperation (that is, the goal of the calculation), the required data set, the data processing process, etc., and can send a data application request to the first node and each second node. The request can carry relevant information of the data application and can be used to request the generation of a data application by the first node or the second node. After receiving the data application request, the first node and the second node generate a data application based on the relevant information of the data application, that is, locally store the relevant information of the data application, and after generating the data application, can notify the first platform that the first node or the second node has already generated a data application by sending a data application request response message to the first platform.

[0069] In actual applications, before sending the first information to the first platform, the first node needs to access the first platform. Correspondingly, before the first platform sends the first information to each second node, each second node also needs to access the first platform.

[0070] Based on this, in one embodiment, the communication method is It may further include the step of accessing the first platform.

[0071] Here, the first node accessing the first platform can be understood as the first node establishing a communication connection with the first platform, and the access process may specifically include processes such as registration and login. Exemplarily, after the data requester and the data provider reach a cooperation intention offline, they can conclude an Internet connection contract on the first platform. Next, the data requester enters the management interface of the first node waiting for registration, requests the first platform to obtain the deployment packet of the first node, installs the deployment packet of the first node on the local server of the first node waiting for registration, and can obtain the registered first node. The data provider enters the management interface of the second node waiting for registration, requests the first platform to obtain the deployment packet of the second node, installs the deployment packet of the second node on the local server of the second node waiting for registration, and can obtain the registered second node. The first node and the second node respectively perform network information configuration so that the first node and the second node can communicate with the first platform. Next, the first node and the second node respectively dock with the first platform, and the first platform activates the accounts of the first node and the second node. The first node and the second node can respectively use the activated accounts to log in to the first platform. The login parameters may include information such as the username, password, and institution ID (i.e., the ID of the first node and the ID of the second node). After the first platform receives the login requests of the first node and the second node, if the corresponding login parameters are correct, the first platform can return a login response message to the first node and the second node.

[0072] In actual application, the first node and the second node may access the first platform synchronously (i.e., simultaneously) or asynchronously.

[0073] In actual application, the first platform can provide the algorithm packets required for the calculation to the first node and / or the second node.

[0074] Based on this, in one embodiment, when the first information is used for joint calculation between the first node and at least one second node, and the first information includes algorithm information required for the calculation, the communication method is Sending a first request to the first platform based on the algorithm information required for the calculation, where the first request is used to request the acquisition of algorithm packets required for the calculation; Receiving the algorithm packets sent by the first platform based on the first request.

[0075] Here, it is understandable that a part of the algorithms required for the calculation may be deployed in the first node, that is, at least one algorithm packet required for the calculation is set locally in the first node. At this time, the first request may be used to request other algorithm packets required for the calculation other than the algorithm packets set by itself.

[0076] In actual application, after receiving the first request sent by the first node based on the algorithm information required for the calculation, the first platform can, based on the first request, send the algorithm packets required for the calculation to the first node.

[0077] In actual applications, each second node can send a third request to the first platform based on the algorithm information required for the calculation. The third request is used to request the acquisition of algorithm packets required for the calculation. After receiving the third request sent by each second node, the first platform can send the algorithm packets required for the calculation to each second node based on the third request. Understandably, a part of the algorithm required for the calculation may be deployed in each second node, and at least one algorithm packet required for the calculation set locally in each second node may be the same or different. Therefore, the algorithm packets requested by the third request sent by each second node may also be the same or different.

[0078] In actual applications, the first node and the second node may synchronously acquire the algorithm packets required for the calculation from the first platform, or may asynchronously acquire the algorithm packets required for the calculation from the first platform.

[0079] In actual applications, the algorithm packet may also be referred to as an algorithm component, etc., and can be understood as an installation packet for deploying one or more algorithms. The embodiments of the present disclosure do not limit the name of the algorithm packet as long as its function is realized. Also, the algorithms corresponding to the algorithm packets may include extreme gradient boosting (XGBOOST), logistic regression, decision trees, etc. The embodiments of the present disclosure do not limit the type of the algorithm as long as its function is realized.

[0080] In actual application, when the first information is used for collaborative computing between the first node and at least one second node, and the first information includes algorithm information required for the computing, after the first platform receives at least one algorithm packet sent by the first platform based on the first request, the first platform uses the first information and the received at least one algorithm packet to perform collaborative computing with the at least one second node to obtain a first calculation result.

[0081] Based on this, in one embodiment, when the first information is used for collaborative computing between the first node and at least one second node, and the first information includes algorithm information required for the computing, the communication method is It may further include the step of using the first information and the received algorithm packet to perform collaborative computing with the at least one second node to obtain a first calculation result.

[0082] Correspondingly, after each second node receives at least one algorithm packet sent by the first platform based on the third request, by using the first information and the received at least one algorithm packet to perform collaborative computing with the first node, the first node can obtain a first calculation result.

[0083] Here, the specific method of collaborative computing between the first node and the at least one second node can be set according to requirements, such as vertical federated learning, and the embodiments of the present disclosure are not limited thereto.

[0084] In actual application, when the first information is used for the calculation of at least one second node, after each second node receives at least one algorithm packet sent by the first platform based on the third request, the second node performs calculation by using the first information and the received at least one algorithm packet to obtain a third calculation result, and can send the third calculation result to the first platform. After the first platform receives the third calculation results sent by each second node and obtains at least one third calculation result, the first platform determines a second calculation result by using the first information and the at least one third calculation result, and can send the second calculation result to the first node. Here, the specific method for the first platform to determine the second calculation result by using the first information and the at least one third calculation result can be set according to requirements, such as performing parameter fusion by using the algorithm specified in the first information, and the embodiments of the present disclosure are not limited thereto.

[0085] Based on this, in one embodiment, when the first information is used for the calculation of at least one second node, the communication method may further include: receiving the second calculation result sent by the first platform, where the second calculation result is determined by the first platform by using the first information and at least one third calculation result, and each third calculation result is calculated by one second node by using the first information.

[0086] In actual applications, when the first information is used for the calculations of multiple second nodes, after each second node receives at least one algorithm packet sent by the first platform based on the third request, the second node performs calculations using the first information and the at least one received algorithm packet to obtain a third calculation result, and can send the third calculation result to the first platform. After the first platform receives the third calculation results sent by each second node to obtain multiple third calculation results, the first platform determines a second calculation result using the first information and the multiple third calculation results, and can send the second calculation result to the first node.

[0087] In actual applications, when the first information is used for the calculation of one second node, after the second node receives at least one algorithm packet sent by the first platform based on the third request, the second node performs calculations using the first information and the at least one received algorithm packet to obtain a third calculation result, and can directly send the third calculation result to the first node. Here, to ensure data security, when the second node sends the third calculation result to the first node, it can encrypt by adopting the algorithm specified by the first information.

[0088] Correspondingly, in one embodiment, when the first information is used for the calculation of one second node, the communication method may further include the step of receiving the third calculation result sent by the second node, where the third calculation result is calculated by the second node using the first information and at least one algorithm packet required for the calculation.

[0089] In actual applications, in order to improve the security of data sharing, each second node uses a predetermined second policy (specific policies can be set according to requirements, such as policies for verifying the legitimacy of the first node, and the embodiments of the present disclosure are not limited thereto) to authenticate the first node. If the authentication is successful, further, the first information is used to perform joint calculations with the first node so that the first node obtains a first calculation result, or calculations are performed using the first information to obtain a third calculation result.

[0090] In actual applications, data requesters and data providers can perform data directory alignment, that is, make the names of the fields included in the data stored by both parties match. Thereby, situations such as the inability to match an appropriate data provider for the data requester due to the non - matching of the field names included in the data stored by the data requester and the data provider can be avoided, and the calculation efficiency can be improved.

[0091] In actual applications, before storing data, the first node and the second nodes can perform data storage according to the names of predetermined fields during data input, so that the names of the fields included in the data stored in the first node and each second node match.

[0092] Based on this, in one embodiment, before transmitting the first information to the first platform, the communication method may further include: obtaining second information, where the second information includes the names of the fields included in the data input to the first node; using a first database to calibrate the names of the fields included in the data input to the first node to obtain calibrated second information, where the first database includes the names of a plurality of predetermined fields; and storing the data input to the first node based on the calibrated second information.

[0093] In actual applications, each second node can execute the steps of: obtaining sixth information before receiving the first information sent by the first platform, where the sixth information includes the names of fields included in the data input to the second node; using a second database to calibrate the names of fields included in the data input to the second node to obtain calibrated sixth information, where the second database includes the names of a plurality of predetermined fields; and storing the data input to the second node based on the calibrated sixth information. Here, the first database includes the same field names as the second database.

[0094] In actual applications, the first node and each second node may achieve directory alignment through information exchange. In other words, through information exchange, the names of fields included in the data stored in both (i.e., the data requester and the data provider) are made to match.

[0095] Based on this, in one embodiment, before sending the first information to the first platform, the communication method includes: obtaining third information, where the third information includes the names of fields included in the data stored in the first node; obtaining fourth information of each second node, where the fourth information includes the names of fields included in the data stored in the second node; for each of the second nodes, determining whether the names of fields included in the data stored in the second node match the names of fields included in the data stored in the first node based on the third information and the fourth information of the second node; If the name of the field included in the data stored in the second node does not match the name of the field included in the data stored in the first node, the step of the second node transmitting the third information to the second node so that the second node can use the third information to update the name of the field included in the stored data may be further included.

[0096] In actual application, if the name of the field included in the data stored in the second node matches the name of the field included in the data stored in the first node, the first node can transmit the seventh information to the second node, and the seventh information represents that the name of the field included in the data stored in the second node matches the name of the field included in the data stored in the first node. When receiving the seventh information, the second node can determine that it is not necessary to update the name of the field included in the data stored in itself.

[0097] In one embodiment, the step of obtaining the fourth information of each second node is The step of sending a second request to each second node, where the second request is used to request the acquisition of the fourth information of the second node, The step of receiving the fourth information sent by each second node based on the second request may be included.

[0098] In actual applications, in order to improve the calculation efficiency, before at least one second node performs calculations corresponding to the first information, the first platform can verify the availability of the data stored in each second node by using the fourth information of each second node. Specifically, the first platform obtains the fourth information of each second node, and uses the fourth information and a predetermined first policy to verify the availability of the data stored in each second node. After the availability of the data is verified (the availability of the data passes the verification), the first information can be sent to each second node. Here, the first policy is used to verify whether there is any illegal data and / or private data in the data stored in each second node (for example, whether the bit length of the identity certificate number meets the requirements), whether the data sample satisfies a normal distribution, etc. The specific policy can be set according to requirements. The embodiments of the present disclosure do not limit this as long as its function is realized.

[0099] In actual applications, when the availability of the data stored in each second node in the at least one second node is verified, the first platform can send fifth information to the first node. The fifth information indicates that the availability of the data stored in the at least one second node has been verified (the availability has passed the verification). After receiving the fifth information, the first node performs joint calculations with the at least one second node. In this way, the calculation efficiency can be improved.

[0100] Based on this, in one embodiment, when the first information is used for joint calculations between the first node and at least one second node, the communication method is receiving the fifth information sent by the first platform, where the fifth information indicates that the availability of the data stored in the at least one second node has been verified, and After receiving the fifth information, performing collaborative computing with the at least one second node to obtain a first calculation result, in other words, when receiving the fifth information transmitted by the first platform (i.e., when receiving the fifth information), performing collaborative computing with the at least one second node to obtain a first calculation result, where the fifth information represents that the availability of the data stored in the at least one second node has been verified, and the step may further be included.

[0101] In actual applications, to ensure data security, the communication between the first node and the first platform, the communication between the first platform and each second node, and the communication between the first node and each second node can perform encrypted transmission using a predetermined algorithm. The predetermined algorithm may include a privacy calculation algorithm, specifically, it may include an inadvertent transmission algorithm, etc. The specific type of the predetermined algorithm can be set according to requirements, and the embodiments of the present disclosure do not limit this as long as its function is realized.

[0123] In one embodiment, the communication method may further include the step of accessing the first platform.

[0124] Here, it should be noted that since the specific processing process of the second node has been described in detail above, it will not be repeated here.

[0125] In the communication method provided by the embodiments of the present disclosure, a first node transmits first information to a first platform, the first information is used for collaborative computing between the first node and at least one second node, or for the calculation of at least one second node, the first information includes related information required for the calculation, the first platform receives the first information transmitted by the first node, transmits the first information to each second node, and the second node receives the first information transmitted by the first platform. In the solution provided by the embodiments of the present disclosure, a data requester (i.e., the first node) transmits a calculation requirement (i.e., the first information) to the first platform, whereby the first platform can match a data provider (i.e., the second node) based on the calculation requirement. In other words, the first platform transmits the calculation requirement to a data provider that matches the calculation requirement, whereby the data provider can perform a calculation based on the requirement of the data requester, and further, the data requester can obtain a calculation result that matches its own requirement.

[0126] Also, in various embodiments of the present disclosure, based on the calculation requirement of the data requester, in a scenario where the user privacy requirement of the data requester is protected and the data of the data provider does not appear (i.e., the data does not leave the domain of the data provider), it can be realized that the data of the data provider accesses the first platform.

[0127] Thirdly, in various embodiments of the present disclosure, the first platform can verify the availability of the data of the data provider, thereby ensuring data packet legality and / or regulatory compliance and further ensuring data security.

[0128] Hereinafter, the present disclosure will be described in more detail with reference to application examples.

[0129] In this application example, the first node is called a DRN, the first platform is called a DSSP or a DSP, the second node is called a DSN, a DRN is deployed for data consumers, and a DSN is deployed for data providers.

[0130] Hereinafter, with reference to FIG. 3, a process for realizing data circulation by accessing data on both the data consumer side and the data provider side to DSSP or DSP will be described.

[0131] As shown in FIG. 3, when the data of the data consumer needs to participate in the calculation, the process of realizing data access and data circulation on the premise that the data does not appear may include the following steps.

[0132] In step 301, the data provider logs in (i.e., accesses) to the DSSP (or DSP) via the DSN. The login parameters may include a username, a password, a DSN ID, etc., and then step 302 is executed.

[0133] In step 302, the DSSP returns a login response to the DSN, and then step 303 is executed.

[0134] In step 303, the data consumer logs in (i.e., accesses) to the DSSP via the DRN. The login parameters may include a username, a password, a DRN ID, etc., and then step 304 is executed.

[0135] In step 304, DSSP returns a login response to DRN and then executes step 305.

[0136] In step 305, DRN sends a data usage request (i.e., the fourth request) to DSSP and then executes step 306.

[0137] Here, the data usage request may include the first information, i.e., data provider information participating in the current calculation (e.g., DSN ID), data requester information (e.g., DRN ID), required algorithm information, etc.

[0138] In step 306, DSSP generates a data application (or project) and then executes step 307.

[0139] In step 307, DSSP sends a data application request to DRN and then executes step 308.

[0140] In step 308, DRN returns a data application request response to DSSP and then executes step 309.

[0141] In step 309, DSSP sends a data application request to DSN and then executes step 310.

[0142] Here, DSSP can send a data application request to DSN based on the request (i.e., demand) of the data requester, i.e., the data application request may include the first information.

[0143] In step 310, DSN returns a data application request response to DSSP and then executes step 311.

[0144] In step 311, DSN sends an algorithm download request to DSSP and then executes step 312.

[0145] In step 312, the DSN obtains (i.e., downloads) the algorithm from the DSSP, and then executes step 313.

[0146] In step 313, the DRN sends an algorithm download request to the DSSP, and then executes step 314.

[0147] In step 314, the DRN obtains (i.e., downloads) the algorithm from the DSSP, and then executes step 315.

[0148] In step 315, the DRN sends a data calculation request (such as vertical federated learning) to the DSSP, and then executes step 316.

[0149] In step 316, the DSSP sends a data calculation request to the DSN, and then executes step 317.

[0150] In step 317, the DSN and the DRN perform data calculation, and then execute step 318.

[0151] Here, the DSN and the DRN adopt the algorithm agreed upon in this data application to perform joint calculation.

[0152] In step 318, the DRN obtains the result (i.e., the first calculation result), in other words, the data requester obtains the desired data.

[0153] In actual application, step 301 and step 303 may be performed synchronously (i.e., simultaneously), and step 311 and step 313 may also be performed synchronously.

[0154] The following will describe, with reference to FIG. 4, a process for realizing data circulation in which the data requirer does not need to provide data and only the data on the data provider side accesses the access DSSP (or DSP).

[0155] As shown in FIG. 4, when the data of the data requirer does not need to participate in the calculation, the process of realizing data access and data circulation on the premise that the data does not appear may include the following steps.

[0156] In step 401, log in (i.e., access) to the DSSP via the data provider DSN. The login parameters may include the user name, password, DSN ID, etc., and then execute step 402.

[0157] In step 402, the DSSP returns a login response to the DSN, and then executes step 403.

[0158] In step 403, the data requirer logs in (i.e., accesses) to the DSSP via the DRN. The login parameters may include the user name, password, DRN ID, etc., and then execute step 404.

[0159] In step 404, the DSSP returns a login response to the DRN, and then executes step 405.

[0160] In step 405, the DRN sends a data usage request (i.e., the fourth request) to the DSSP, and then executes step 406.

[0161] Here, the data usage request may include the first information, that is, the data provider information participating in the current calculation (for example, DSN ID), the data requirer information (for example, DRN ID), the required algorithm information, etc.

[0162] In step 406, the DSSP generates a data application (or project), and then executes step 407.

[0163] In step 407, DSSP sends a data application request to DRN and then executes step 408.

[0164] In step 408, DRN returns a data application request response to DSSP and then executes step 409.

[0165] In step 409, DSSP sends a data application request to DSN and then executes step 410.

[0166] Here, DSSP can send a data application request to DSN based on the request (i.e., demand) of the data requester, that is, the data application request may include the first information.

[0167] In step 410, DSN returns a data application request response to DSSP and then executes step 411.

[0168] In step 411, DSN sends an algorithm download request to DSSP and then executes step 412.

[0169] In step 412, DSN obtains (i.e., downloads) the algorithm from DSSP and then executes step 413.

[0170] In step 413, DRN sends a data calculation request (such as blacklist query) to DSSP and then executes step 414.

[0171] In step 414, DSSP sends a data calculation request to DSN and then executes step 415.

[0172] In step 415, DSN performs data calculation and then executes step 416.

[0173] Here, the DSN performs corresponding calculations locally based on the agreed algorithm and the demand of the DRN (i.e., the first information).

[0174] In step 416, the DSN transmits the data calculation result (i.e., the third calculation result) to the DSSP, and then executes step 417.

[0175] Here, the DSN can transmit the calculation result to the DSSP by means of a privacy calculation method such as an accidental transmission technology.

[0176] In step 417, the DSSP performs data calculation, obtains the result (i.e., the second calculation result), and then executes step 418.

[0177] Here, the DSSP calculates locally based on the calculation result transmitted by the DSN to obtain the final data calculation result (i.e., the second calculation result).

[0178] In step 418, the DSSP transmits the data calculation result to the DRN.

[0179] In actual application, steps 401 and 403 may be performed synchronously (i.e., simultaneously).

[0180] Hereinafter, the configurations of the DSN and the DRN will be described with reference to FIG. 5.

[0181] In this application embodiment, DSN and DRN can be understood as data access devices for realizing data circulation by accessing a large amount of data to DSSP (or DSP) on the premise that local data does not appear. As shown in FIG. 5, both DSN and DRN include a connection module, a data calculation module, and a data directory management module. Here, the function of the connection module may include communicating with the DSSP network, that is, communicating with DSSP and maintaining the connection relationship with DSSP (that is, maintaining). In other words, maintaining communication with DSSP, sending requests (such as the first request) to DSSP, and receiving requests (such as the data application request) and responses from DSSP. The function of the data calculation module may include receiving the data application request of the connection module and performing data calculations such as model training, model output, and calculation result output based on the data application request. The function of the data directory management module may include publishing the data directory of the local-side data source (that is, the name of the field included in the data on this side) to DSSP and performing data directory alignment for the opposite-side data source. Here, the external connection of DSN and DRN (that is, the connection between DSSP and the local-side data source) is shown in FIG. 6.

[0182] Hereinafter, with reference to FIG. 7, another data circulation process when local data does not appear will be described.

[0183] As shown in FIG. 7, DSSP includes a management support platform (DSS-M: Data Sharing Service-Management), a trading platform (DSS-T: Data Sharing Service-Trading), and a calculation adjustment platform (DSS-C: Data Sharing Service-Calculation). The data circulation process among DRN, DSSP, and DSN may include the following steps.

[0184] In step 701, the connection module of the DRN sends a data usage request (i.e., the fourth request) to the DSSP (or DSP), and then executes step 702.

[0185] Here, the data requester sends a data usage need to the DSS-C via the connection module of the DRN. In other words, the data usage request may include information such as the data requester and data application (such as the first information).

[0186] In step 702, the DSSP sends a data usage request to the connection module of the DSN, and then executes step 703.

[0187] Here, the DSS-C sends a data usage need to the connection module of the DSN.

[0188] In step 703, the connection module of the DSN sends a data usage request to the data calculation module of the DSN, and then executes step 704.

[0189] Here, the connection module of the DSN transfers the data usage request to the data calculation module.

[0190] In step 704, the data calculation module of the DSN sends a data call request to the local data source (i.e., the database of the data provider), and then executes step 705.

[0191] Here, the data call request can be understood as a data read request.

[0192] In step 705, the local data source authenticates the current data call, i.e., authenticates that the requester and data application are legal, and then executes step 706.

[0193] Here, in the authentication process, if the data requester determines that the data requester and the data application are legal and permitted, the data requester can permit the current data reading.

[0194] In step 706, the data stream of the local data source is transmitted to the data calculation module of the DSN, and then step 707 is executed.

[0195] In step 707, the data calculation module of the DSN performs calculations including modeling, operations (such as operations of a specified algorithm), etc. based on the usage requirements, and then step 708 is executed.

[0196] In step 708, the data calculation module of the DSN transmits the result (i.e., the third calculation result) to the connection module of the DRN via the connection module of the DSN.

[0197] In this application embodiment, before the data is circulated, it is necessary to align the data directory of the data requester with the data directory of the data provider. Hereinafter, with reference to FIGS. 8 and 9, two methods for aligning the data directory will be described.

[0198] In actual applications, the data provider can publish its own data directory in the DSSP (or DSP) via the data directory management module of the DSN. That is, the directory of the names of the fields included in the data of the data provider is published so that the data requester can check whether the data of the data provider meets the needs of the data requester. Although the same type of data exists for both the data provider and the data requester, if the names of the data directories are inconsistent, the data requester may not be able to match with the data provider that meets the requirements, so data directory alignment is necessary.

[0199] As shown in FIG. 8, the DRN and DSN use the data directory management module to align the names of the fields included in the input data, so as to match the data directories of the same type of data between the data requester and the data provider, that is, the names of the fields included in the data can be matched.

[0200] Specifically, the data directory management module can provide a data directory standard name library (that is, the first database and the second database). The data provider or the data requester inputs the data directory name to the data directory management module, that is, inputs the name of the field. The data directory management module automatically matches the standard name closest to the input directory name from the data directory standard name library based on the input directory name, and presents it to the data provider or the data requester, and asks the data provider or the data requester to confirm whether it is the directory name they want to input. If it is "yes", the data provider or the data requester further inputs the next data directory name based on the requirement. If it is not the directory name that the data provider or the data requester wants to input, the data provider or the data requester can be made to return to changing the directory name input to the data directory management module.

[0201] In actual application, if the standard name that matches one directory name input several times (the number threshold can be set according to the requirement) by the data provider or the data requester cannot be found all the time, the data directory management module can input the directory name into the candidate directory list of the data directory standard name library, and be reviewed by the DSSP (or DSP), and determine whether to record the directory name in the data directory standard name library.

[0202] As shown in FIG. 9, another process of data directory alignment may include the following steps.

[0203] In step 901, the DRN requests the DSN to feedback a data field, and then executes step 902.

[0204] Here, the data requester can send the name of a data field that may be the same as that of the DSN to the connection module of the DSN via the connection module of the DRN, and request the data provider to feedback the data field.

[0205] In step 902, the DSN feedbacks the name of the data field to the DRN, and then executes step 903.

[0206] Here, the data provider receives the request via the connection module of the DSN, and feedbacks the name of the field included in the data stored in itself to the data requester.

[0207] In step 903, the DRN determines whether the names of both data fields are the same. If they are the same, it feedbacks to the connection module of the DSN that the names of both fields match (i.e., the seventh piece of information). If the names do not match, it feedbacks to the connection module of the DSN the new name of the field corresponding to the data requester (i.e., the third piece of information), and then executes step 904.

[0208] Here, the data requester obtains the name information of the data field of the data provider (i.e., the fourth piece of information) via the connection module of the DRN. If both names are the same, it feedbacks to the connection module of the DSN of the data provider that the names of both fields match (i.e., the seventh piece of information). If the names do not match, it feedbacks to the connection module of the DSN of the data provider the new name of the field corresponding to the data requester (i.e., the third piece of information).

[0209] In step 904, the DSN changes the name of its own data field according to the demand.
