The rapid advancement of healthcare technology has emphasized the importance of continuous, real-time monitoring of patients' vital signs and critical parameters. This project presents the design and implementation of an integrated health monitoring system The Innovative Security Solutions for Cloud-Based Key Access approach introduces a sophisticated access management system specifically designed for the digital environment, enabling smooth transitions and hierarchical access policies. This system empowers data owners from various organizational units to utilize any public cloud infrastructure as though it were a private cloud, ensuring stringent security. Regardless of their location, users within the organization can securely access the community cloud, both within and outside the corporate network. To control key access, our method leverages polynomial interpolation and Shamir's Secret Sharing algorithm. This approach is ideal for hierarchical organizational structures, offering a secure, flexible, and tiered access mechanism. Through the use of topological collation in directed graphs, including self-loops, only users with the necessary support from peers or higher-level users can access the key. This effectively mitigates the challenges associated with migrating mission-critical data to the community cloud. Additionally, our scheme significantly reduces storage overhead in both public and private contexts, while maintaining efficient key derivation computations. From a security perspective, our solution is resilient against collaboration attacks and ensures key in distinguishability. Importantly, the key is never stored, thereby eliminating the risk of data breaches from key exposure. In essence, our key access management system provides a robust solution for organizations seeking to exploit the benefits of public cloud systems while maintaining strict control over access to sensitive data. It incorporates advanced security features, reduces storage requirements, and removes the risks associated with key disclosure.
