Privacy Information Security Protection of the Internet of Things in the Big Data Environment

With the deep integration of big data and the Internet of Things (IoT), IoT applications are becoming increasingly widespread. However, this has led to prominent privacy and information security issues. This paper analyzes the current situation, lists the harms caused by privacy breaches, and examines the reasons behind them. It also discusses research findings both domestically and internationally, explores the applicability and challenges of different technologies, and proposes various privacy protection solutions. The study shows that the comprehensive use of multiple technologies and strategies can enhance IoT privacy information security and ensure the healthy development of the IoT.
