In this paper, we propose a delay-tolerant secure long-term health care scheme, RCare, for collecting patient’s sensitive personal health information (PHI). Specifically, to minimize the overall health care cost, RCare provides network connectivity to rural areas using conventional transportation vehicles (e.g., cars, buses) as relay nodes. These vehicles are expected to store, carry, and forward...
In this paper, we propose a patient-centric personal health information (PHI) sharing and access control scheme, SPS. Proposed SPS encompasses identity based cryptography to ensure security and privacy of PHI by using short digital signature and patient's pseudo-identity. SPS relieves the health service provider's (HSP) additional burden for PHI storage, management, and maintenance by incorporating...
In this paper, we propose an efficient and secure patient-centric access control (PEACE) scheme for the emerging electronic health care (eHealth) system. In order to assure the privacy of patient personal health information (PHI), we define different access privileges to data requesters according to their roles, and then assign different attribute sets to the data requesters. By using these different...
