Enhancing Cloud Healthcare Security Using Fine-Grained Access Control with Weight-Improved Particle Swarm Optimization and Zero-Knowledge Proofs

Abstract

Background Information: The improved security framework for cloud healthcare systems presented in this research combines Zero-Knowledge Proofs (ZKP), Weight-Improved Particle Swarm Optimization (WIPSO), and fine-grained access control. By improving privacy and data security, the framework guarantees safe access to private medical data. Objectives: Using WIPSO and ZKP to provide fine-grained access control will improve cloud healthcare security by reducing unwanted access and protecting user privacy, data integrity, and confidentiality. Methods: By optimizing access control policies, a WIPSO algorithm increases the effectiveness of security. ZKP provides safe, private access to cloud-stored medical data by ensuring user authentication without disclosing private information.
Results: Significant gains in access control efficiency and security are made possible by the suggested framework, which also lowers computing costs and prevents unwanted access attempts while safeguarding private medical information. Conclusion: A strong, scalable solution for cloud healthcare security is offered by the combination of WIPSO and ZKP, which offers efficient, privacy-preserving, and fine-grained access control over sensitive medical data.
