Asimina Tsouplaki, Carol Fung, Christos Kalloniatis · Internet of Things · 2025
The proliferation of Internet of Things (IoT) devices has brought tremendous convenience in our daily lives but has also brought significant privacy concerns. In recent years, many solutions have been found in the literature to address these challenges through advanced technologies such as Artificial Intelligence (AI). This paper aims to provide a comprehensive survey of the current landscape of IoT privacy, focusing on the role of AI in enhancing privacy measures. We categorize critical privacy challenges, outline AI strategies to address these challenges, and present AI-driven solutions that have shown real and substantial results in major sectors. We examine various AI techniques, assess their effectiveness, and highlight existing research gaps to inform future researchers. Our main contributions include a taxonomy of AI applications for IoT privacy, an analysis of AI-driven privacy solutions, and a discussion on the ethical implications and compliance requirements. This paper is recommended to researchers, practitioners, and policymakers seeking to develop secure and privacy-aware IoT systems. Unlike previous surveys that analyze thoroughly individual privacy-preserving methods, this study provides a multi layer synthesis of AI techniques tailored to IoT architectures and deployment realities, presenting a taxonomy grounded in both theoretical robustness and implementation feasibility.
