DSAS A SECURE DATA SHARING AND AUTHORIZED SEARCHABLE FRAMEWORKS FOR E-HEALTH CARE SYSYTEM (KEY IJP************297)
Abstract
In the realm of e-healthcare, the exchange of encrypted Personal Healthcare Records (PHRs) between patients and medical professionals has enhanced access to quality medical services. However, challenges persist in efficiently searching for information within encrypted PHRs, along with the costs associated with ensuring continuous online availability of doctors for remote monitoring and research. This project introduces a novel and secure Proxy Searchable Re-Encryption method, named DSAS, designed to enable effective and secure remote PHR monitoring and research. DSAS prioritizes the privacy and confidentiality of PHRs by limiting access to authorized doctors and research institutions. Additionally, it facilitates the delegation of medical decisions by the primary healthcare provider, ensuring that patient records are encrypted before uploading to a cloud server. This setup allows remote access for secondary healthcare providers or research institutions, thereby restricting direct access to sensitive information stored on the cloud server. The security of the proposed scheme is rigorously formalized, and performance analysis confirms its effectiveness.
