Privacy-Preserving AI Systems: Strategies for Responsible and Ethical Data Governance

Abstract

The rapid adoption of artificial intelligence (AI) in data-driven environments has intensified concerns surrounding privacy, security, and ethical data usage. This paper presents a comprehensive analysis of privacy-preserving AI, focusing on practical strategies for responsible data handling in modern intelligent systems. It begins by examining foundational privacy principles and the ethical implications of large-scale data collection and automated decision-making. The study then investigates key technical challenges, including data sensitivity, re-identification risks, and the trade-offs between model performance and privacy protection. To address these challenges, the paper systematically evaluates state-of-the-art privacy-preserving techniques such as differential privacy, federated learning, homomorphic encryption, and secure multi-party computation, highlighting their applicability across diverse AI workflows.
