Problems solved by technology
[0003] However, if non-intrusive load monitoring is used by malicious attackers, there will be potential risks to the privacy of users such as electricity consumption information.
At present, noise is usually added to the electricity consumption data before the smart meter releases the electricity consumption data, in order to protect the user's privacy and reduce the accuracy of the operation status of the electricity consumption equipment.

The invention provides an energy consumption data encryption method, a noise generation method, equipment and a storage medium, and the encryption method comprises the steps of obtaining an input total accuracy rate which represents the accuracy degree of analyzing the on-off state of a plurality of pieces of energy consumption equipment in the time period through the encrypted data of the energy consumption data; determining a differential privacy coefficient according to the total accuracy rate through a preset constraint relationship; and generating noise according to the determined differential privacy coefficient, wherein the noise is used for encrypting the energy consumption data of the energy consumption equipment group to obtain the encrypted data. According to the invention, the noise in the energy consumption data added in each time interval in a time period can be determined according to the total accuracy expected to be reached by a user, so that the on-off state set of a plurality of energy consumption devices analyzed through the energy consumption data with the noise added can meet the total accuracy.
Description
technical field [0001] The present application relates to the technical field of data processing systems and methods, and in particular to an encryption method using energy data, a noise generation method, a device, and a storage medium. Background technique [0002] Non-intrusive load monitoring (Non-Intrusive Load Monitoring, NILM) can obtain the operating conditions of each user's electrical equipment by analyzing the total power consumption data (such as total voltage, total current, etc.) of multiple electrical equipment of the user. Telegram information. Through non-intrusive load monitoring, it can provide users with power consumption strategies, fault monitoring and fault analysis of power consumption equipment, and can also provide reference information for power grid planning of power companies. [0003] However, if non-intrusive load monitoring is used by malicious attackers, there will be potential risks to the privacy of users such as electricity consumption in...
