[0023] In one embodiment, if Figure 1 As shown, the present application discloses a sensitive data protection method for a new energy power grid system, which specifically includes the following steps: S10: Acquire server data to be stored, and acquire a data type based on the server data to be stored.

[0024] Specifically, in the process of storing the server data, the data type corresponding to the server data to be stored is obtained by performing type analysis on the server data to be stored.

[0025] S20: According to the data type, multiple node blockchains are obtained in a preset data blockchain mapping thread pool.

[0026] In this embodiment, the node blockchain refers to the blockchain used to store server data.

[0027] Specifically, according to the data type, multiple blockchains for storing server data are obtained in a data blockchain mapping thread pool preset in the cloud storage system.

[0028] S30: Storing the server data to be stored in the multiple node blockchains and generating a data smart contract.

[0029] In this embodiment, the data smart contract refers to an agreement on the contract terms for automatically executing and processing server data stored in the node blockchain.

[0030] Specifically, the server data to be stored is stored in the corresponding node blockchain, and the server data is stored in multiple node blockchains according to the data type to form redundant backup and fault-tolerant processing. Distributed storage can eliminate the risk of single point failure in the existing cloud storage system, thereby ensuring the security and reliability of the server data stored in the cloud storage system.

[0031] Furthermore, while the server data is stored in the node blockchain, an agreement on the contract terms for automatically executing the server data stored in the node blockchain is generated.

[0032] S40: Perform data encryption processing on the server data in the node blockchain according to the data smart contract.

[0033] Specifically, the server data stored in the node blockchain is encrypted according to the data smart contract to realize automatic encryption operation on the server data, further improve the privacy of the server data, and improve the security and privacy protection capabilities of the server data in the cloud storage system.

[0034] In this embodiment, during the storage of server data, the type of the server data to be stored is analyzed to obtain the data type corresponding to the server data to be stored. According to the data type, multiple node blockchains are obtained in the data blockchain mapping thread pool preset in the cloud storage system. The node blockchain refers to the blockchain used to store server data, and the server data to be stored is stored in the corresponding node blockchain. The server data is dispersedly stored in multiple node blockchains according to the data type to form redundant backup and fault-tolerant processing. Distributed storage can eliminate the risk of single point failure in the existing cloud storage system, thereby ensuring the security and reliability of the server data stored in the cloud storage system. While storing the server data in the node blockchain, a data smart contract is generated. The data smart contract refers to an agreement on the contract terms for automatically executing the server data stored in the node blockchain. According to the data smart contract, the server data stored in the node blockchain is encrypted to realize automatic encryption operation on the server data, further improve the privacy of the server data, and improve the security and privacy protection capabilities of the server data in the cloud storage system.

[0035] In one embodiment, if Figure 2 As shown, in step S40, the server data in the node blockchain is encrypted according to the data smart contract, specifically including: S41: Generate a data processing request according to the data smart contract, and build an encryption thread pool that is compatible with the server data to be processed according to the data processing request.

[0036] Specifically, a data processing request is generated according to the data smart contract, and the initial encryption thread pool in the cloud storage system is initialized. For example, according to the type of server data in each node blockchain, the parameters of the initial encryption thread pool in the cloud storage system are reallocated so that the allocated encryption thread pool matches the server data to be processed.

[0037] S42: Obtain a mapping relationship between the server data in the node blockchain and the encryption thread pool.

[0038] S43: According to the mapping relationship, the server data in the node blockchain is mapped to the encryption thread pool for execution, a data encryption processing rule adapted to the data processing request is obtained, and data encryption processing is performed based on the data encryption processing rule.

[0039] Specifically, through the mapping relationship between the server data in the node blockchain and the encryption thread pool, the server data in the node blockchain is mapped to the encryption thread pool for operation, so as to mobilize the corresponding encryption thread pool to perform parallel encryption processing on the server data in the node blockchain, thereby improving the orderliness of the encryption processing of the server data in the node blockchain, and controlling the encryption thread pool to perform encryption processing on the server data in the node blockchain through encryption processing rules, thereby improving the efficiency of encryption processing of the server data in the node blockchain.

[0040] In one embodiment, if Figure 3 As shown, after step S40, the sensitive data protection method of the new energy power grid system further includes: S401: Generate a second data processing request according to the data smart contract, and re-divide the data capacity of the node blockchain according to the second data processing request to obtain a data capacity threshold that meets the second data processing request.

[0041] Specifically, according to the second data processing request, the node blockchain in the cloud storage system is initialized, such as redividing the data capacity of the node blockchain according to the capacity of the received server data, and setting the maximum number of message receptions for each node blockchain, so that the storage of the server data to be stored meets the optimal operating efficiency of each node blockchain in the cloud storage system, thereby obtaining a message capacity threshold that meets the second data processing request.

[0042] S402: Adjust the data storage time of the server data in each node blockchain so that the adjusted data storage time meets the processing requirements of the data capacity threshold, thereby obtaining the target data storage time.

[0043] Specifically, the data storability time refers to the length of time that the node blockchain stores the server data. During the data storability time, the stored server data can only be stored in the node blockchain, reducing the probability of the same server data being repeatedly stored in multiple node blockchains. For example, the storage time of the server data is determined based on the capacity of the node blockchain, and this time is used as the data storability time, so that the adjusted data storability time meets the processing requirements of the data capacity threshold, thereby obtaining the target data storability time.

[0044] S403: According to the target data storage time, the data renewal time of the server data in each node blockchain is adjusted to obtain the target data renewal time that meets the second data processing request.

[0045] Specifically, according to the target data storability time, the server data renewal time of each node blockchain is dynamically adjusted. For example, the target data storability time of each node blockchain is monitored separately. When the target data storability time ends, the target data renewal time is called to automatically renew the server data of the node blockchain. During the data renewal time, the storability of the server data is changed through the node blockchain, and the change result is returned to the node blockchain and the corresponding server data storability time is updated, thereby completing the automatic update and renewal of the server data in the node blockchain.

[0046] S404: Generate a data processing time rule according to the target data storage time and the target data renewal time, and perform data update processing on the server data in the node blockchain based on the data processing time rule.

[0047] Specifically, corresponding data processing time rules are generated according to the adjusted target data storage time and target data renewal time, so as to facilitate rapid data storage and update processing of server data in the node blockchain according to the data processing time rules, thereby improving the processing efficiency of the cloud storage system for server data.

[0049] S60: According to the data processing rule, the server data in the node blockchain is mapped to the data processing thread pool for data processor adaptation, and the data processor with the best adaptation degree is selected to process the server data in the node blockchain.

[0050] Specifically, through the data smart contract, a data processing rule is generated for automatic execution of the server data in the node blockchain. According to the data processing rule, the server data in the node blockchain is mapped to the data processing thread pool, and the server data in the node blockchain is processed by the data processor with the best adaptation degree, so that the server data in each node blockchain is decoupled and distributed to the corresponding data processor for data processing through the corresponding data processing thread pool, so that the server data in each node blockchain in the cloud storage system can be processed in parallel, thereby improving the orderliness of server data processing, and reducing the operation and maintenance cost of the cloud storage system by mapping the server data in each node blockchain to different thread pools for parallel processing.

[0051] In one embodiment, if Figure 5As shown, in step S60, that is, according to the data processing rule, the server data in the node blockchain is mapped to the data processing thread pool for data processor adaptation, and the data processor with the best adaptation degree is selected to process the server data in the node blockchain, specifically including: S61: According to the data processing rules, data renewal processing is performed on the server data in the node blockchain to obtain renewal server data running according to the target data renewal time.

[0052] Specifically, according to the data processing rules, data renewal processing is performed on the server data in the node blockchain. For example, when the cloud storage system receives new input of server data, the data processing rules are called to renew the newly input server data, so that the server data newly input into the node blockchain is cyclically renewed according to the target renewal time to obtain the renewed server data.

[0053] S62: Perform data processing thread pool adaptation processing on the renewal server data, and construct a thread pool mapping relationship between the renewal server data and the data processing thread pool.

[0054] Specifically, the renewal server data is matched to the data processing thread pool through the data uniqueness of the renewal server data, such as data classification and data unique identification code, to obtain the thread pool mapping relationship between the renewal server data and the data processing thread pool. S63: According to the thread pool mapping relationship, the renewal server data is adapted to the data processors in the data processing thread pool, and the optimal data processor with the best adaptation degree is selected.

[0055] S64: Establishing a data distribution relationship between the renewal server data and the optimal data processor, and performing data processing on the renewal server data according to the data distribution relationship.

[0056] Specifically, the renewal server data and the data processor are adapted in the data processing thread pool to obtain the optimal data processor that is best adapted to the current renewal server data. The renewal server data is distributed and processed through the data distribution relationship between the optimal data processor and the renewal server data. The data distribution process of the renewal server data is dynamically operated and maintained by the data processor to improve the intelligence of the cloud storage system.
