For the purposes of making the objects, technical solutions and advantages of the present application more apparent, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure. Embodiments and features of embodiments in this application may be combined with each other arbitrarily without conflict. Also, while a logical order of illustration is depicted in the flowchart, in some cases the steps shown or described may be performed in a different order than presented.

The terms first and second in the description and claims of the present application and in the above-described figures are used for distinguishing between different objects and not for describing a particular sequential order. Furthermore, the term "include" and any variations thereof is intended to cover non-exclusive protection. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those listed steps or elements but may include other steps or elements not listed or inherent to such process, method, article, or apparatus. The term "plurality" in the present application may mean at least two, for example, two, three or more, and embodiments of the present application are not limited.

In the technical scheme, the data are collected, transmitted, used and the like, and all meet the requirements of national related laws and regulations.

Before describing a data updating method provided in the embodiments of the present application, for convenience of understanding, a technical background of the embodiments of the present application is first described in detail.

Currently, in the process of processing data by cooperation of multiple devices, in order to protect private data of each device, the multiple devices are required to be provided with a computing node and a local database, wherein the computing node is used for processing and operating acquired data locally by the devices, and the local database is used for storing the processed and operated data by the devices. And, the multiparty device may also need to verify the processed data at the local node. The method of processing operation adopted by the device is generally privacy calculation, and the device needs more calculation resources when accessing devices with different levels or devices with different authorities because sensitive data or privacy data are involved, so that usable sensitive data can be obtained.

Specifically, existing privacy calculations are applied in different fields such as: (1) The privacy computing method based on the container technology can determine a privacy data protection strategy based on the use habit and the historical privacy data of the user, and protect the privacy data of the user according to the protection strategy. (2) Privacy calculation is carried out in the block chain facing to the auditing service, equipment obtains data to be audited according to equipment data of more than two parties, a server database is accessed to obtain an operation instruction, and the data to be audited is forwarded according to the operation instruction. (3) The method is applied to cross-domain data calculation, and by constructing a zero-trust data storage environment, the data provider only needs to audit the application of the data user, and the application can approve the application to use the sensitive data of the data provider without malicious leakage behaviors. In the privacy computation related to the application method, the device needs to access the sensitive database and calculate based on the privacy disclosure coefficient to ensure that the data meets the security requirement. However, the above method may still cause leakage of part of user data in the process of calculation, and the device needs to additionally access databases of a plurality of servers, and calculate whether the data meets the security requirement for the private data multiple times. Taking litigation data processing in the government affairs field as an example, when a worker (such as a case transactor) of any place court determines that the data sent by the case related party in the civil litigation are abnormal, a server of the place court needs to calculate updated data for the case related party at a local server node after obtaining the user data. In a scenario where there is a higher demand for data security and data processing efficiency, such as in the field of civil litigation, it is difficult for the currently employed method to satisfy the demands of the server for data processing and updating.

Thus, in fields such as civil litigation, the update of user data by a server is inefficient.

In order to solve the above problems, the present application provides a data updating method for improving the updating efficiency of a server to user data.

For example, the computing node may be deployed at the first server, and the computing node of the first server may perform privacy computation according to data of any user provided by the first client, and provide update information for the user to the first client. When privacy calculation is performed, the method is not limited to privacy disclosure coefficient calculation, and secure multiparty calculation (secure multi-party computation, MPC) and federal learning calculation (Federated Learning, FL) such as quick secure exchange can be performed according to the data of the multiparty server, so that update information can be obtained by integrating multiparty data, and update efficiency of the server to user data can be improved.

By way of example, the method and the device can also realize that the computing resources are provided only at the first server, so that the first client side can be saved from purchasing high-performance computing power resources. In specific implementation, the method adopts a domestic cryptographic algorithm (or called national cryptographic algorithm), encrypts data aiming at actual service scenes, and realizes encrypted transmission of calculation results through a data sandbox mechanism, so that the security of sensitive data of a client is further improved. The data sandboxed mechanism refers to a device deployment data sandboxed component that may be used for data caching, determining an algorithm protocol (i.e., determining an algorithm to generate a key). The first server may encrypt or decrypt the data with the private key in the data sandboxed component, thereby further improving the security of the data. Data sandbox mechanism

The present application may also set a client-server (client-server) mode. The server may act as a server device. The client may act as a client device. The server has a computing node deployed therein. The client is deployed with a database. In this application, the first server and the second server may be server devices. The client-server is classified based on the algorithm component, so that the times of additional access of the client to databases of servers of different levels can be reduced, the first server and the second server which are in the same node process the data and provide operation results for the first client, the informatization operation and maintenance cost of the client can be reduced, and the problems of limited access capacity of the client and cross-level database access can be solved.

Fig. 1 schematically shows a flow chart of a data updating method. Illustratively, the method is performed by a first server.

Referring to the flow shown in fig. 1, the method provided in the embodiment of the present application may include the following steps:

in step 101, a first server obtains user information and first data of a first user from a first client, where the first data is data of litigation cases related to the first user.

Step 102, the first server sends a data request to the second server according to the user information of the first user and the first data.

Step 103, the second server obtains the second data according to the data request.

Step 104, the second server sends the second data to the first server.

In step 105, the first server determines updated information for litigation cases associated with the first user based on the second data.

In step 106, the first server provides the update information to the first client, and the update information is used for updating the first data by the first client.

Step 101 is described below. The first server obtains user information and first data of a first user from a first client, wherein the first data is data of litigation cases related to the first user.

Illustratively, the first server is any one of a plurality of servers. The plurality of servers further includes a second server, and the first server and the second server may be servers of the same level in the same region, or may be servers of the same level in different regions. For example, the first server and the second server are both provincial server nodes in the same region, or the first server and the second server are provincial server nodes across regions. In the litigation system, the inspection province level server and the inspection province level server, the inspection province level server and the court province level server all belong to the same-level server, and the inspection province level server and the inspection base level server (or the court base level server) belong to different-level servers.

It will be appreciated that any provincial server having a computing node deployed can be used as the first server, the first server being the party that receives the user information and the first data of the first user, and the second server being the party that receives the data request of the first server.

Alternatively, the first server or the second server may include a plurality of server nodes, and the plurality of server nodes may transmit data to each other. The first server and the second server may deploy a data sandbox, i.e. implement a data sandbox mechanism in the respective servers, the data transmitted in the data sandbox being encrypted data. For example, according to a data sandbox mechanism, the first server and the second server encrypt data according to a key, and transmit the encrypted data. The key may be generated based on a cryptographic algorithm, such as SM2 or SM4 algorithm, as used in the present application.

Illustratively, in litigation systems, either the first server or the second server is at a different level than the first client. The first client may have a database for the first client to receive user information and first data sent by the first user and for the first client to receive update information sent by the first server.

Illustratively, the first user refers to a user who sends data to be updated. The data to be updated sent by the first user comprises user information and first data of the first user, wherein the user information and the first data can be used for the first server to acquire update information from the second server, so that the first server can provide the update information for the first user.

For example, as shown in fig. 2, litigation systems can be divided into extranet and intranet. The government intranet may include a first server, a second server, and a first client. The plurality of servers of the litigation system can be classified into provincial servers (a review provincial server and a court provincial server) and basic-level servers (a review base-level server and a court base-level server) according to the level of the servers. The provincial server of the inspection department can be a first server, the provincial server of the court can be a second server, and the first server and the second server can mutually transmit data without limiting access additionally. And the inspection yard provincial server and the court provincial server can both carry out algorithm scheduling or service scheduling according to the deployed sandboxed program. The algorithm schedule may be used to determine the same privacy calculation key between the first server and the second server, and the traffic schedule may be used to transfer data between the first server and the second server. The specific process of algorithm scheduling and service scheduling may be determined based on the needs of the first server and the second server according to specific privacy calculations of the manager of the servers. The first client may include a plurality of clients, only one client is taken as an example in fig. 2, in practical situations, there may be a server corresponding to a plurality of clients, and each client may refer to the flow of obtaining the update information by the first client in the flow of obtaining the update information, so that details are not repeated. The first client may include a WEB page (WEB) front end and a database, the WEB front end may be used for the first client to obtain user information and data of a user, and the database may be used for the first client to store the user information and data of the user and also to store update information sent by the first server after the privacy calculation is completed. The government external network can comprise a privacy computing node front end processor, and the front end processor can be used for service scheduling and algorithm scheduling of the first server. The front-end processor can be set according to the needs of the manager of the server, and the application is not repeated.

In addition, in a litigation system, the first user may be the interested party of the litigation case. The user information may be information such as the name, identity information, etc. of the interested party in the litigation case. The first data may be data of litigation cases related to the interested party.

Optionally, the first client may generate a key according to a cryptographic algorithm, and encrypt the user information and the first data according to the key, so as to improve security of the first server for obtaining the user information and the first data of the first user. The first client may request the first server to receive encrypted first user data of the first client, where the first user data includes user information of the first user and the first data, and the request may be a post request. Correspondingly, the first server can receive the data of the first user sent by the first client after encryption, and then decrypt the data in the data sandbox to obtain the user information and the first data of the first user. The cryptographic algorithm comprises an SM2 or SM4 algorithm.

For example, the first client may generate a node certificate through the SM2 algorithm, and the certificate may include a pair of public and private keys, where the public key may be denoted as PKh, the private key may be denoted as Sk1, and the PKh may be used as a key of the first client. A clerk at the first client may log into the first client. The first client may obtain monetary Data and user information related to the first user in litigation cases, the monetary Data and user information being noted as Data. The first client may encrypt Data according to PKh to obtain Data'. The first client may use Sk1 as the digital signature for Data' and Sk1 as the post request. The first client may send Data' and post requests to either server node of the first server via hypertext transfer protocol (hypertext transfer protocol, HTTP). The server node of the first server may generate a public key PK1 according to the SM2 algorithm, PK1 for verifying Sk1 sent by the first client. After verification, the server node decrypts Data' in the Data sandbox to obtain Data of the first user of the first client, wherein the Data is user information and first Data of the first user of the first client.

Step 102, the first server sends a data request to the second server according to the user information of the first user and the first data.

Alternatively, the data request may include any data identification that may be generated by the first server based on the user information of the first user and the first data. The data request may be for the first server to request second data from the second server. The first device may determine the data identity based on the user information and the value or data type of the first data, and use the data identity as the data request.

Step 103, the second server obtains the second data according to the data request.

Alternatively, the second server may comprise a plurality of server nodes. The server node may be configured to obtain node data, which may be used by the first server to determine update information. After the second server obtains the data request, the second server may obtain, according to the data request, data related to the first user from a plurality of server nodes corresponding to the second server as second data, and the second server may send the second data to the first server. That is, the second data may be data transmitted by the same user (i.e., the first user) at a plurality of server nodes of the second server, and the data includes accurate data or real data corresponding to the first data of the user, so that the update information determined based on the second data may improve the accuracy of the update information.

Alternatively, the second data may correspond to data of the same user as the first data. The second data may comprise a database from any server node. The database of the second server comprises user information corresponding to any user and data of the user. The second server may determine a plurality of data of the first user, i.e., determine the second data, among the plurality of server nodes according to the user information of the first user.

Optionally, the second server may audit the data request, obtain the data identifier in the data request after the audit is passed, and determine the user information of the first user according to the data identifier.

Step 104, the second server sends the second data to the first server.

Alternatively, the second server may send the second data to the first server via a data sandbox. The data sandbox of the second server may be used to store the second data.

Alternatively, the second server may encrypt the second data according to the key of the second server, and send the encrypted second data to the first server.

Correspondingly, the first server receives the second data.

In step 105, the first server determines updated information for litigation cases associated with the first user based on the second data.

Alternatively, the update information may include intersection data or a data update model. The update information may be determined by the first server from second data of the second server. Based on the data sandboxed mechanism, the update information may be intersection data or a data update model determined from the encrypted second data.

Alternatively, the first server may determine update information according to the data of the first server and the second data, where the update information is intersection data. The data of the first server comprises third data, which may be data of the first user in a server node of the first server. The plurality of server nodes of the second server may include a first server node and a second server node, and the second data may include first node data from the first server node and second node data from the second server node. The first server can determine intersection data according to the first node data and the second node data, and can further determine intersection data according to the first node data, the second node data and the third data, so that the first server can obtain more accurate updating information. The first server may encrypt the third data and then obtain intersection data with the encrypted second data.

Optionally, the first server may further determine update information according to the data of the first server and the second server, where the update information is a data update model. The data of the first server includes fourth data, which may be data of the first user in a server node of the first server. The plurality of server nodes of the second server may include a third server node and a fourth server node, and the second data may include third node data from the third server node and fourth node data from the fourth server node. The first server can determine intersection data according to the third node data and the fourth node data, and can further determine a data update model according to the third node data, the fourth node data and the fourth data, so that the first server can obtain more accurate update information.

It should be noted that the first server may select only the intersection data of the second data as the update information, or only the data update model obtained from the second data as the update information, or may provide the first client with the update information including the intersection data and the data update model, with both the intersection data and the data update model as the update information.

Optionally, the first server may determine the training data and the labeling information corresponding to the training data according to the configured model file, and the training process of the data update model may be determined by a server manager of the configuration file. The input data of the trained data updating model can be false data or error data of the first user, the output data can be updated data of the first user, and the updated data has accuracy. It is understood that the model files generated based on the requirements of the claimant and the model training process corresponding to the model files are not limited in the application.

Optionally, the first server may also determine, according to the configured model file, labeling information corresponding to the training data according to the third node data, the fourth node data, and the fourth data as training data, to obtain a trained data update model. It should be noted that the above training process may be performed by the first server according to the requirement of the server manager, and the specific training process is not limited in this application.

For example, the first server may obtain an expert model file sent by a case handling person, determine a data update calculation model according to the expert model file, input the data update model according to the first data, and output the data update model as update information for the first data.

Optionally, the first server may overlay the first data in the data sandbox according to the update information, so that the first server provides the update information to the first client, so that the first client may update the first data according to the update information.

Optionally, the process of step 105 is described below with the first server being a server node of the provincial server for inspection and the second server being a server node of the provincial server for court, and the update information being intersection data.

Optionally, the server node of the provincial server of the inspection department can establish a node cooperation application with the server node of the provincial server of the court through a distributed-deployment privacy computing platform.
