Secure and Scalable Personal Health Record Sharing in Cloud Computing

Problem Definition

Problem Description: The main problem that needs to be addressed is the secure sharing of personal health records (PHRs) in cloud computing while ensuring scalability and flexibility in access control. Currently, the storage of PHRs by third-party providers in the cloud raises concerns about privacy and unauthorized access to sensitive patient information. Although encryption can address some of these concerns, there are still challenges related to key management, access control, and user revocation. In order to ensure that patient information remains secure and private in PHRs, a patient-centric framework is needed along with mechanisms for efficient data access control. This framework should leverage attribute-based encryption techniques to encrypt each patient's PHR file and reduce key management complexity.

By dividing users into multiple security domains and implementing multi-authority ABE, a high level of privacy can be maintained while also supporting efficient user and attribute revocation. Overall, the problem to be addressed is how to securely share personal health records in the cloud while ensuring scalability, flexibility, and efficient access control. This can be achieved through the implementation of a novel patient-centric framework and mechanisms for data access control using attribute-based encryption techniques.

Proposed Work

The proposed work aims to address the security and privacy concerns related to the sharing of personal health records (PHRs) in cloud computing using attribute-based encryption (ABE). The project titled "Scalable and Secure Sharing of Personal Health Records in Cloud Computing using Attribute-based Encryption" focuses on developing a patient-centric framework and a suite of mechanisms for data access control to PHRs stored in a semi-trusted server. By utilizing ABE techniques, each PHR patient's file is encrypted to ensure privacy and confidentiality. The key management complexity is reduced by dividing users in the PHR system into multiple security domains, and multi-authority ABE is used to provide a high degree of privacy to the patient's PHR. This novel approach also supports efficient user/attribute revocation and break-glass access under emergency scenarios.

The project falls under the category of C#.NET Based Projects and the subcategory of .NET Based Projects. The implementation of this system will address the challenges of privacy exposure, scalability in key management, flexible access, and efficient user revocation in sharing personal health records securely in cloud computing environments.

Application Area for Industry

This project can be applied in various industrial sectors such as healthcare, pharmaceuticals, insurance, and telemedicine where the secure sharing of personal health records (PHRs) is crucial. Industries in these sectors face challenges related to privacy concerns, unauthorized access to sensitive patient information, key management complexity, and efficient access control. By implementing the proposed solutions of a patient-centric framework and attribute-based encryption techniques, these industries can ensure the security, scalability, and flexibility of sharing PHRs in cloud computing environments. The benefits of adopting this project include enhanced privacy and confidentiality of patient information, reduced key management complexity, support for efficient user and attribute revocation, and the ability to provide break-glass access in emergency situations. Overall, the implementation of this system will help industries in these sectors address the challenges they face in securely sharing personal health records while complying with data protection regulations and maintaining patient trust.
