Abstract

A personal health record, also referred to as a PHR system, is a sophisticated medical database that can be accessed by both patients and medical professionals. This type of database is known as a PHR system. On the other hand, there is always the possibility that unauthorized users or semi-trusted third parties will gain access to personally identifiable health information. The purpose of this application is to propose a patient-centered PHR sharing architecture that respects patients’ right to privacy while also giving them full authority over their own medical information (PHRs). Under this architecture, all protected health records (PHRs) are encrypted utilizing multi- authority attribute-based encryption prior to being outsourced. This eliminates the need for key hosting and enables access control that is more granular to be applied to PHRs. In addition, a proposal has been made for an anonymous authentication between the cloud and the user. The objective of this proposal is to maintain the integrity of data that is stored on the cloud without revealing the identity of the user at any point during the authentication process. It is possible for encrypted PHRs to withstand attempts at collusion and to not be forged during the entirety of the sharing process, which strengthens the patients’ control over their personal health records (PHRs).

Keywords: Anonymous authentication, attribute-based signature, multi-authority attribute-based encryption, personal health record.
