Multi-Party Privacy-Preserving Logistic Regression with Poor Quality Data Filtering for IoT Contributors

Abstract

Nowadays, the internet of things (IoT) is used to generate data in several application domains. A logistic regression, which is a standard machine learning algorithm with a wide application range, is built on such data. Nevertheless, building a powerful and effective logistic regression model requires large amounts of data. Thus, collaboration between multiple IoT participants has often been the go-to approach. However, privacy concerns and poor data quality are two challenges that threaten the success of such a setting. Several studies have proposed different methods to address the privacy concern but to the best of our knowledge, little attention has been paid towards addressing the poor data quality problems in the multi-party logistic regression model. Thus, in this study, we propose a multi-party privacy-preserving logistic regression framework with poor quality data filtering for IoT data contributors to address both problems. Specifically, we propose a new metric gradient similarity in a distributed setting that we employ to filter out parameters from data contributors with poor quality data. To solve the privacy challenge, we employ homomorphic encryption. Theoretical analysis and experimental evaluations using real-world datasets demonstrate that our proposed framework is privacy-preserving and robust against poor quality data.

Analysis of IoT Security Challenges and Its Solutions Using Artificial Intelligence

“…The forecasting accuracy of a security model can be harmed by extreme variation, overfitting, expensive processing, and time-consuming model setup [ 93 ]. A high-dimensional dataset with many security attributes evaluated according to how important or relevant they are may make it easier to create an IoT security model [ 102 ]. Existing approaches include the correlation coefficient, the chi-squared test, and analysis of variance.…”

Non-Interactive and Secure Data Aggregation Scheme for Internet of Things

“…Based on homomorphic encryption technology, Al-Zubaidie et al [17] used a secure and lightweight signature algorithm to prevent user information leakage. Edemacu et al [18] proposed a multi-party privacy-preserving logistic regression framework and filtered out low-quality data for data contributors. Yang et al [19] designed an encryption scheme on account of elliptic curve encryption, which reduces the computation and communication costs.…”
