The technological advent of Blockchain, Bigdata, Cloud, and AI made it easier to be stored retrieved Electronic Health Record (EHR) data then used by patients, doctors, research groups for treatments analytics. Blockchain security ensures the patients' records with smart contracts due most reliable secure platform many industries such as finance, IoT, healthcare, logistics management. innovative use in healthcare industry enables a system provide privacy complete protection record able integrate various entities sector. criticality acquiring, storing, securing EHR is essential faster services. Integrating multiple providers accrues benefits quick insurance approvals dealing emergencies critical situations. It expedites medical access companies, primary providers, pharmaceuticals, laboratories reap efficiently. challenges are storage, which can addressed security, integrating Bigdata provides huge scalability, performance store maintain Often securing, maintaining involves excessive administrative operative costs. Most work done on technology frameworks implementation but part storage maintenance yet focused area, how manage this long term. This paper intends best based architectural framework systems at lesser cost compared other Infrastructure facilities utilizing inexpensive hardware grouped into clusters assigned resources share across network easy even after procuring securely.

The rise of data-sharing platforms, driven by public demand for open data and legislative mandates, has raised several pertinent issues. These encompass uncertainties over accuracy, provenance lineage, privacy concerns, consent management, the lack equitable incentives providers. advanced nature blockchain makes it well-suited to address these concerns. Yet, limitations blockchains, particularly their restricted performance, scalability, high cost, make them less adept at managing four “V” big - volume, variety, velocity, veracity. As body work proposing blockchain-based solutions grows, so does confusion in selecting between terms sharing mechanisms, services, quality applications. In this paper, we aim fill knowledge gap through an in-depth survey architectures We first identify key challenges existing techniques lay out foundations blockchains. Our focus then shifts intersection sharing, wherein clarify landscape propose a reference architecture sharing. Subsequently, explore various industrial applications spanning healthcare, smart grids, transportation, decarbonization. For each application, draw from real-world deployments present lessons learned implementation Lastly, shed light on current research avenues further study space. This paper aims serve as comprehensive resource researchers/practitioners looking navigate complex terrain solutions.

A number of recent studies have shown that wastage and inefficiency are a significant problem in all global healthcare systems. One initiative could radically improve the operational efficiency health systems is to make paradigm shift data ownership—that is, transition such patient-centric model management by deploying blockchain technology. Such development would not only an economic impact, cutting wastage, but deliver social benefits improving patient outcomes satisfaction. However, blockchain-based solution presents considerable challenges.

With the rapid development of artificial intelligence (AI) in healthcare industry, sharing personal data plays an essential role advancing medical AI. Unfortunately, is plagued by challenges like ambiguous ownership and privacy leakage. Blockchain, which stores hash shared on-chain ciphertext off-chain, treated as a promising approach to address above issues. However, this lacks flexible reliable mechanism for incremental updates same case data. To avoid overhead authentication, access control, rewards caused changes, we propose blockchain trusted execution environment (TEE)-based privacy-preserving scheme that supports updates. Based on chameleon TEE, achieves verification without changing In scheme, concerns, off-chain are protected through symmetric encryption, whereas verification, decryption, computation performed within TEE. The experimental results show feasibility effectiveness proposed scheme.
