Problems solved by technology

However, the power transaction data information under the blockchain is public in the nodes, and attackers can maliciously mine and utilize the transaction relationship between the accounts of different power users by analyzing and sorting out the transaction data information and analyzing the transaction relationship between the accounts of different power users. Transaction information, so that the privacy of the trader's account information is disclosed

Embodiment 1

[0044] A data processing method based on power trading, including cloud, the cloud processing method for data includes:

[0045] S10. Carry out real-time fixed-point sampling of the power transaction data in the region to obtain real-time data values ​​and real-time change increments, and randomly store the data in several servers after being divided into blocks, encrypted and numbered; the method of storing the data to the servers is :

[0046] S11. Appending a BLOCK identifier at the end of each encrypted data;

[0047] S12. Create metadata for indexing encrypted data, and store the metadata in the main storage medium of the server;

[0048] S13. Store metadata and encrypted data in n Cache storage media of the server, n≥1; the server includes m Cache storage media, m≥n; n Cache storage media where a batch of encrypted data is stored At least one of them is not full;

[0049]S14. Merge the data in the full Cache storage medium into a file and store it in the slave storage...

Embodiment 2

[0058] A data processing method based on power trading, including cloud, the cloud processing method for data includes:

[0059] S10. Carry out real-time fixed-point sampling of the power transaction data in the region to obtain real-time data values ​​and real-time change increments, and randomly store the data in several servers after being divided into blocks, encrypted and numbered; the method of storing the data to the servers is :

[0060] S11. Appending a BLOCK identifier at the end of each encrypted data;

[0061] S12. Create metadata for indexing encrypted data, and store the metadata in the main storage medium of the server;

[0062] S13. Store metadata and encrypted data in n Cache storage media of the server, n≥1; the server includes m Cache storage media, m≥n; n Cache storage media where a batch of encrypted data is stored At least one of them is not full;

[0063] S14. Merge the data in the full Cache storage medium into a file and store it in the slave storag...

Embodiment 3

[0076] A data processing system based on power trading, including a cloud, where the cloud includes a sampling module, a data processing module, and an index generation module;

[0077] The sampling module performs real-time fixed-point sampling of the power transaction data in the area to obtain real-time data values ​​and real-time change increments, and the data processing module randomly stores the data in several servers after being divided into blocks, encrypted and numbered;

[0078] The index generation module stores the number of the encrypted data rather than the data itself in the block chain; the storage method is:

[0079] Generate a string similar to the form of the identification data in the original data, calculate the difference between the original data and the generated string, and the string generated at each sampling moment is the same string; the original data includes identification data and other data ;

[0080] The difference is sorted according to th...

Abstract

The invention relates to the field of information technology security, provides a data processing method and system based on power transaction, and is used for solving the problem of power transactiondata leakage. In the data processing method based on power transaction, a cloud is provided, and the method comprises the steps: S10, carrying out the real-time fixed-point sampling of power transaction data in a region, obtaining an instant data value and a real-time change increment, partitioning, encrypting and numbering the data, and randomly storing the data in a plurality of servers; and S20, storing the serial number of the encrypted data instead of the data in the blockchain. And the security of data storage is improved.

Description

technical field [0001] The invention relates to the field of information technology security, in particular to a data processing method and system based on power trading. Background technique [0002] With the development of smart grid and big data technology, the data sharing mode of data mining and analysis of the state of the power industry by using the released power system big data has become the development trend of the electric power information age. However, while data sharing brings convenience, it is also accompanied by the risk of personal privacy data leakage, so the release of privacy-protected data has attracted widespread attention. [0003] Traditional privacy-preserving data release models, such as k-anonymity, l-diversity, t-approximation and other models, they generalize all data records into several groups of records according to the characteristics of the original data, not only making each group in each group Records cannot be distinguished from each o...
