SECURE ACCESS TO MEDICAL HEALTH RECORD THROUGH ATTRIBUTE BASED ENCRYPTION IN CLOUD

The patient-centric model, Personal Health Records (PHR) have completely transformed the interchange of health information. PHR services give patients the ability to create, manage, and control their own personal health information on a centralised web-based platform, which improves the effectiveness of storing, retrieving, and sharing medical data. In order to give patients full control over their medical information, our research focuses on presenting a cutting-edge architecture for secure exchange of personal health records in cloud computing. By encrypting the PHR files, patients can enforce access control policies, determining who can access their health data and to what extent. This granular control enables patients to selectively share their records with healthcare providers, family members, or friends, according to their preferences and requirements. The encryption ensures that only authorized users, possessing the necessary decryption keys or attributes, can access the sensitive information stored in the cloud. The proposed framework addresses the security and privacy concerns associated with sharing personal health records in cloud environments. It emphasizes the importance of patient autonomy and control, aligning with the patient-centric approach. By providing patients with the ability to encrypt their PHR files, the framework empowers them to safeguard their privacy while still facilitating data sharing for improved healthcare outcomes. The proposed this framework, suitable cryptographic techniques such as Attribute-Based Encryption (ABE) or other fine-grained access control mechanisms can be employed. These techniques ensure that patients have the authority to manage their personal health records securely, while cloud servers serve as mere storage repositories without compromising data privacy. The study in this paper aims to establish a secure and patient-centric approach to sharing personal health records in cloud computing. By encrypting PHR files and granting patients complete control over access, this research work contributes to the realization of patient empowerment, privacy preservation, and efficient health data exchange.
