Abstract	The rapid expansion of Artificial Intelligence (AI) has created significant opportunities for healthcare, finance, education, telecommunications, smart cities, cybersecurity, and other data-intensive sectors. However, conventional AI development generally requires centralized collection and processing of large datasets, creating substantial concerns regarding privacy, data ownership, security, and regulatory compliance. Federated Learning (FL) has emerged as a promising distributed machine-learning paradigm that enables multiple organizations or devices to collaboratively train AI models without directly sharing their raw data. Instead of transferring datasets to a central repository, participating clients train models locally and share model updates with an aggregation mechanism. This study examines the role of Federated Learning in developing privacy-preserving AI applications through a qualitative and comparative analysis of contemporary research. It examines the fundamental architecture of FL, major privacy-enhancement techniques, application domains, security threats, and implementation challenges. Particular attention is given to secure aggregation, differential privacy, homomorphic encryption, trusted execution environments, and decentralized learning architectures. The study demonstrates that FL can substantially reduce direct exposure of sensitive datasets while enabling collaborative model development across distributed environments. However, FL should not be considered inherently private because model updates may themselves reveal sensitive information and may be vulnerable to poisoning, inference, and reconstruction attacks. Effective privacy preservation therefore requires multiple complementary security mechanisms. The study concludes that the future of privacy-preserving AI will depend on the integration of Federated Learning with robust cryptographic techniques, trustworthy AI principles, efficient communication protocols, and appropriate governance frameworks.
