Abstract

The rapid advancement of decentralized healthcare information exchange (HIE) networks has transformed the sharing of medical data, enabling real-time collaboration, improved patient care, and enhanced interoperability across healthcare providers. However, the inherent openness and distributed architecture of these networks expose them to numerous security threats, particularly cyber intrusions that can compromise sensitive patient data. Conventional intrusion detection systems (IDS) often struggle to maintain trust, integrity, and transparency in decentralized environments. To address these challenges, blockchain technology has emerged as a promising solution due to its decentralized, tamper-proof, and transparent nature. This review paper explores the integration of block chain-based intrusion detection techniques within decentralized healthcare information exchange networks. It examines the architecture, benefits, and limitations of existing blockchain-IDS frameworks, evaluates state-of-the-art methods, and discusses how smart contracts, consensus algorithms, and cryptographic techniques enhance intrusion detection capabilities. The paper further identifies current challenges, including scalability, data privacy, and computational overhead, while proposing future research directions to advance secure, reliable, and efficient healthcare data exchanges.
