[0040] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. 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.

[0041] With the development of Internet of Things technology, intelligent monitoring equipment, such as ball control equipment, is becoming more and more popular. The data collected by these intelligent monitoring devices usually need to be managed.

[0042] Traditional data management methods are usually based on the decentralized and tamper-proof characteristics of blockchain technology, and the collected data is uploaded to the blockchain for data storage.

[0043] However, existing intelligent monitoring equipment has shortcomings in data security and privacy protection. For example, the data collected by the surveillance equipment is easily attacked and tampered by hackers, and traditional data management methods cannot ensure the security of the data uploaded to the blockchain. Therefore, traditional monitoring data management methods have the problem of low data reliability.

[0044] In view of this, the present application provides a data management method, device, equipment, readable storage medium and program product, which receives a data collection request sent by a control ball device, can determine the data source corresponding to the data type through an oracle and a smart contract, and obtain the target data from the data source through the oracle, and can upload the target data to the blockchain through the smart contract, wherein the data collection request includes the data type. In this way, there is no need for the control ball to collect data by itself, but to receive the data collection request sent by the control ball, so that the oracle deployed on the server confirms the secure data source according to the data type included in the data collection request, and then collects the required target data from the data source through the oracle, and uploads the target data to the blockchain, avoiding the problem of low data reliability caused by the lack of security authentication of the data source of the data collected by the control ball device itself in the traditional technology. The present technical solution determines a secure data source through an oracle, and then obtains the target data on the chain from the secure data source, thereby ensuring the reliability of the data.

[0045] The data management method provided in the embodiment of the present application can be applied to Figure 1In the application environment shown. Among them, the control ball device 101 is connected to the server through an external adapter, and the control ball device 101 is deployed with an interface corresponding to the oracle, which can send data requests to the oracle deployed in the server. The number of control ball devices 101 can be multiple, and different control ball devices 101 correspond to unique identifiers; the external adapter supports control ball devices that access different communication protocols. In the embodiment of the present application, the external adapter supports devices that adapt to the MQTT protocol (Message Queuing TelemetryTransport, a lightweight message protocol based on the publish / subscribe mode) and the HTTP protocol (HyperText TransferProtocol, Hypertext Transfer Protocol), and 1 supports cross-chain interoperability protocols, etc.; the server 102 can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides cloud computing services. The server 102 is deployed with an oracle and a smart contract. The oracle can use the related servers of the oracle, and the smart contract can access the blockchain and perform related operations of the blockchain.

[0046] In an exemplary embodiment, Figure 2 As shown, a data management method is provided, which is applied to Figure 1 Taking the server 102 in the example as an example, a oracle and a smart contract are deployed in the server, and the method includes the following steps 201 to 203. Among them:

[0047] Step 201, receiving a data collection request sent by a control ball device.

[0048] The control ball device can be a device used to collect data. Different control ball devices may support different network protocols, such as MQTT protocol, HTTP protocol and cross-chain protocol.

[0049] In an embodiment of the present application, a oracle interface will be deployed on the control ball device so that the control ball device can communicate with the language oracle service.

[0050] In a possible implementation, different control ball devices may collect data of different data types. When the control ball device needs to collect data, the server will receive a data collection request sent by the control ball device, wherein the data collection request includes the data type.

[0051] The data type may be the type of data that the surveillance device needs to collect, such as temperature, location information, etc.

[0052] Optionally, the server can periodically receive data collection requests sent by the control ball device through the oracle. Optionally, when the control ball device triggers a specific event, the server can receive data collection requests sent by the control ball through the oracle.

[0053] Step 202, determine the data source corresponding to the data type through the oracle and the smart contract, and obtain the target data from the data source through the oracle.

[0054] After receiving the data collection request, the server can determine the data source corresponding to the data type by calling the oracle and the smart contract.

[0055] In the embodiment of the present application, the data source is a data source preset in the smart contract and has been securely authenticated. The data source may be a preset URL, an identifier of a data acquisition device, etc., that is, the data source may also be the control device itself.

[0056] In one possible implementation, a mapping function is stored in the smart contract, and the server can call the mapping function based on the data type through an oracle to determine the data source corresponding to the data type.

[0057] In one possible implementation, a mapping table is stored in the smart contract, and the server can use an oracle to look up the table based on the data type to determine the data source corresponding to the data type.

[0058] Once the data source is determined, the server can obtain the target data from the data source through the oracle. Optionally, the server can call the oracle to directly obtain the target data corresponding to the data type from the data source according to the data type; optionally, after the server calls the oracle to directly obtain the data corresponding to the data type from the data source according to the data type, it will also generate a data source identifier and data acquisition time corresponding to the data source at the same time. The server can use the obtained data, data source identifier and data acquisition time as the target data.

[0059] Step 203: Upload the target data to the blockchain through a smart contract.

[0060] After obtaining the target data, the server can upload the target data to the blockchain through a smart contract.

[0061] In one possible implementation, corresponding processing methods will be set in the smart contract for data of different data types. The server can perform preset processing on the target data through the smart contract to obtain the on-chain data, and then upload the on-chain data to the blockchain.

[0062] Regarding preset processing, optionally, it can be a preset encryption processing. For some data, it may be necessary to upload encrypted data to ensure the security of the data. Before uploading the target data to the blockchain through a smart contract, the server can first determine the preset encryption processing method according to the smart contract to obtain the processed chain data. Then, the server uploads the chain data to the blockchain.

[0063] In another possible implementation, the data collection request also includes a control ball identifier, and the server can determine the target blockchain through the smart contract and the control ball identifier, and then upload the target data to the target blockchain.

[0064] For different control ball devices, the server can set a unique, tamper-proof, and privacy-inclusive control ball identifier for each control ball device during its data life cycle based on blockchain technology. For different control ball devices, the server can upload its corresponding data to a specific blockchain. Therefore, in an embodiment of the present application, the server can determine the target blockchain corresponding to the control ball device through a smart contract and the control ball identifier, and then upload the target data to the target blockchain.

[0065] In a possible implementation, after the server uploads the target data to the blockchain through a smart contract, it can also obtain the on-chain result corresponding to the target data, and then send the on-chain result to the control ball device.

[0066] The above data management method receives the data collection request sent by the control ball device, and can determine the data source corresponding to the data type through the oracle and the smart contract, and obtain the target data from the data source through the oracle, and upload the target data to the blockchain through the smart contract, wherein the data collection request includes the data type. In this way, there is no need for the control ball to collect data by itself, but to receive the data collection request sent by the control ball, so that the oracle deployed on the server confirms the secure data source according to the data type included in the data collection request, and then collects the required target data from the data source through the oracle, and uploads the target data to the blockchain, avoiding the problem of low data reliability caused by the lack of security authentication of the data source of the data collected by the control ball device itself in the traditional technology. The technical solution determines the secure data source through the oracle, and then obtains the target data on the chain from the secure data source, thereby ensuring the reliability of the data.

[0067] In one embodiment, based on the above Figure 2 The embodiment shown, see Figure 3 , this embodiment involves the process of determining the data source corresponding to the data type through an oracle and a smart contract. Figure 3 As shown, step 202 may include step 301 and step 302 .

[0068] Step 301, determine multiple candidate data sources through an oracle and a smart contract.

[0069] Step 302, determine the data source corresponding to the data type from multiple candidate data sources through a oracle.

[0070] In an embodiment of the present application, candidate data sources corresponding to different data types are set in the smart contract. The server can call the oracle to screen each candidate data source according to the data type to determine the data source corresponding to the data type.

[0071] After obtaining the data source corresponding to the data type through the above method, the server can obtain the target data from the data source by calling the oracle. In one possible implementation, the server can obtain initial data from the data source through the oracle, and in the process of obtaining the initial data, generate acquisition process data through the oracle, wherein the acquisition process data at least includes the data source identifier corresponding to the data source and the acquisition time of the initial data. Finally, the initial data and the acquisition process data are used as target data.

[0072] In this way, not only can the data obtained from the data source be uploaded to the blockchain, but the data acquisition process can also be retained, ensuring the richness of the data.

[0073] In one embodiment, referring to Figure 4 , provides an exemplary data management method, which is used in a server, in which an oracle and a smart contract are deployed, and the method can be applied to Figure 1 In the implementation environment shown.

[0074] Step 401, receiving a data collection request sent by a control ball device.

[0075] The data collection request includes the data type.

[0076] Step 402, determine multiple candidate data sources through an oracle and a smart contract.

[0077] Step 403, determine the data source corresponding to the data type from multiple candidate data sources through a oracle.

[0078] Step 404, obtaining initial data from the data source through the oracle, and in the process of obtaining the initial data, generating acquisition process data through the oracle.

[0079] The acquisition process data at least includes a data source identifier corresponding to the data source and the acquisition time of the initial data.

[0080] Step 405: Use the initial data and the acquisition process data as target data.

[0081] Step 406: Preset processing is performed on the target data through the smart contract to obtain the on-chain data.

[0082] Step 407, upload the on-chain data to the blockchain.

[0083] Step 408, obtaining the on-chain result corresponding to the target data.

[0084] Step 409, sending the uplink result to the control ball device.

[0085] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-mentioned embodiments can include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.
