Privacy-Preserving Federated AI Frameworks for Secure Data Collaboration across Distributed Enterprise Cloud Platforms

Abstract

 Privacy-preserving federated artificial intelligence (AI) provides an emerging approach for enabling collaborative machine learning across distributed enterprise cloud platforms without requiring organizations to directly centralize sensitive datasets. Conventional centralized AI architectures often require data to be transferred to common repositories, creating concerns regarding confidentiality, regulatory compliance, data ownership, and security. Federated learning addresses these concerns by allowing participating organizations or cloud environments to train models locally and exchange model updates rather than raw data. However, model updates can still expose sensitive information, while malicious participants, insecure communication channels, and heterogeneous data distributions can affect the reliability of collaborative learning. This study proposes a privacy-preserving federated AI framework for secure data collaboration across distributed enterprise cloud platforms. The framework integrates federated learning with encryption, secure aggregation, differential privacy, participant authentication, access control, anomaly detection, and model governance. The research methodology employs a distributed experimental environment representing multiple enterprise organizations with heterogeneous datasets and cloud infrastructures. Evaluation focuses on model accuracy, communication overhead, convergence time, privacy protection, resilience against malicious participants, and computational cost. Different privacy configurations are compared to examine the trade-off between privacy strength and learning performance. The proposed framework aims to establish a secure and scalable foundation for collaborative AI in environments where data cannot be freely centralized, while maintaining organizational control, auditability, and compliance throughout the federated learning lifecycle
