Embodiment

[0043] Such as figure 1 As shown, the model diagram of the Ubiquitous Power Internet of Things dynamic data release method based on differential privacy in this embodiment uses federated learning to construct the main model and build a distributed RNN model for real-time prediction of the current time based on the currently released data Stamped statistics, and use the predicted values ​​to perform adaptive sampling and adaptive privacy budget allocation.

[0044] Such as figure 2 As shown, a differential privacy-based ubiquitous power Internet of Things dynamic data release method in this embodiment mainly includes the following steps: prediction, adaptive sampling, privacy budget allocation, group merging, noise addition, and release.

[0045] Such as image 3 As shown, the RNN-based network architecture diagram of this embodiment is used to predict the number and data prediction value to be released.

[0046] The whole method steps are as follows:

[0047] 1) Prepare u...

Abstract

The invention discloses a ubiquitous power Internet of Things dynamic data publishing method based on differential privacy in the technical field of information security. The method comprises the following steps: 1) constructing and deploying a federated learning-based RNN model based on a ubiquitous power Internet of Things cloud- side network architecture; 2) introducing differential privacy, designing an adaptive sampling module to judge whether original data is disturbed or not, and through a privacy budget adaptive allocation mechanism, allocating privacy budget more reasonably, and maximizing the utilization of the privacy budget; 3) for sampling point data, reducing the interference of injected noise through a grouping and merging mechanism; and 4) safely and anonymously publishingthe processed data. The method has the advantages that the privacy of the data is protected, background knowledge attacks and differential attacks are resisted, meanwhile, the availability of the published data is guaranteed to the maximum extent, and the purpose of efficient dynamic data security publishing is achieved.

Description

technical field [0001] The invention belongs to the technical field of information security, and in particular relates to a method for publishing dynamic data of the ubiquitous power Internet of Things. Background technique [0002] With the rapid development of information technologies such as cloud computing and the Internet of Things, smart grids are becoming more and more intelligent and efficient. In 2019, the concept of ubiquitous power Internet of Things was proposed. The Ubiquitous Power Internet of Things fully applies modern information technologies such as mobile Internet and artificial intelligence, and advanced communication technologies to realize the interconnection of all things and human-computer interaction in all aspects of the power system. It has the characteristics of comprehensive state perception, efficient information processing, and convenient and flexible applications. The development of the Ubiquitous Power Internet of Things has brought massive ...
