Core Concepts

The author proposes AerisAI, a decentralized collaborative AI framework, to address data privacy issues in federated learning by employing homomorphic encryption and differential privacy techniques.

Abstract

The content discusses the challenges of data privacy in federated learning systems and introduces AerisAI as a solution. It explains how AerisAI improves security, ensures auditability, and preserves privacy while achieving high model performance through innovative techniques like homomorphic encryption and group key management based on CP-ABE.

The proposed framework addresses weaknesses in existing FL systems, such as the need for a centralized server, lack of auditability, and privacy issues related to gradient leakage. By decentralizing the system and implementing advanced encryption methods, AerisAI significantly outperforms state-of-the-art baselines in terms of security and model accuracy.

AerisAI's approach involves aggregating encrypted parameters using blockchain technology without the need for a trusted third party. The framework also perturbs gradients with noise to prevent information leakage while ensuring efficient group key management for scalability.

Overall, AerisAI offers a comprehensive solution for secure and efficient collaborative AI with attribute-based differential privacy.
