Dynamic access policy in cloud-based personal health record (PHR) systems
With the development of cloud computing, an increasing number of users are using cloud-based personal health record (PHR) systems. The PHR is closely tied to patient privacy, and thus existing studies suggest encrypting PHRs before outsourcing. Comparison-based encryption (CBE) was the first to implement time comparison in an attribute-based access policy by means of the forward and backward de...
متن کاملAttribute-based Access Control for Cloud-based Electronic Health Record (EHR) Systems
Electronic health record (EHR) system facilitates integrating patients' medical information and improves service productivity. However, user access to patient data in a privacy-preserving manner is still challenging problem. Many studies concerned with security and privacy in EHR systems. Rezaeibagha and Mu [1] have proposed a hybrid architecture for privacy-preserving accessing patient records...
متن کاملFine-grained Access of Personal Health Record in Cloud Computing
Cloud computing is used broadly in various services which maintain Personal Health Record (PHR). It is an emerging Health-centric model of patient health information interchange. Personal Health Record (PHR) information can be stored in a third party server i.e.Cloud server. The most important issues are fine–grained access, cryptographically enforced data access control, scalability in key man...
متن کاملHCBE: Achieving Fine-Grained Access Control in Cloud-Based PHR Systems
With the development of cloud computing, more and more users employ cloud-based personal health record (PHR) systems. The PHR is correlated with patient privacy, and thus research suggested to encrypt PHRs before outsourcing. Comparison-based encryption (CBE) was the first to realize time comparison in attribute-based access policy by means of the forward/backward derivation functions. However,...
متن کاملConditions potentially sensitive to a Personal Health Record (PHR) intervention, a systematic review
BACKGROUND Personal Health Records (PHRs) are electronic health records controlled, shared or maintained by patients to support patient centered care. The potential for PHRs to transform health care is significant; however, PHRs do not always achieve their potential. One reason for this may be that not all health conditions are sensitive to the PHR as an intervention. The goal of this review wa...
