Secure Data Sharing Architecture for Heterogeneous Information Systems

Abstract

In modern information infrastructures, data is typically distributed across heterogeneous platforms and managed by independent organizations. Ensuring secure and efficient data sharing under such conditions remains a critical challenge. Existing solutions often rely on centralized authorization mechanisms, which limit scalability and system robustness. This study presents a decentralized data sharing architecture that integrates access control, encrypted storage, and distributed audit mechanisms. The proposed system supports flexible permission configuration and fine-grained data management across heterogeneous environments. By introducing dynamic identity authentication and secure transmission protocols, the framework effectively mitigates unauthorized access and data leakage risks. Experimental evaluations show that the proposed architecture achieves high data sharing efficiency while maintaining strong security guarantees, making it suitable for cross-domain information collaboration scenarios.
