Blockchain Integration in Cloud Security : A Case Study Approach
Keywords:
EHRs, dPoS, AWS, PoAAbstract
In this paper, the integration of blockchain technology in cloud security was considered based on its applications in healthcare data management. ForElectronic Health Records (EHRs) stored in cloud based healthcare systems, data confidentiality and privacy is becoming increasingly vulnerable to threats, hence, blockchain becomes a potential solution to secure EHRs and allow better data sharing. Through case study analysis, this research examines three key approaches: Augmenting healthcare with a blockchain, MediBchain, a privacy preserving framework for decentralized healthcare data, and bitcoin for wearable medical devices, hybrid cryptography for wearable medical devices, and a blockchain based framework for secure healthcare data sharing. Strengths and limitations of these blockchain implementations are discussed, along with their potential to facilitate security challenges in a cloud environment. Future research directions for blockchain based healthcare solutions are on scalability, interoperability, and privacy.
