| Abstract | Electronic Health Record (EHR) systems have an abundance of convenience for telediagnosis, medical data sharing and management. The main obstacle for wide adoption of EHR systems is due to the privacy concerns of patients. In this work, we propose a role-based access control (RBAC) scheme for EHR systems to secure private EHRs. In our RBAC, there are two main types of roles, namely independent patients and hierarchically organized medical staff. A patient is identified by his/her identity, and a medical staff is recognized by his/her role in the medical institute. A user can comprehend an EHR only if he/she satisfies the access policy associated with this EHR, which implies a fine-grained access control. A public auditor is employed to verify whether the EHR is correctly encapsulated with the specified access policy, which provides an a priori approach to find fraudulent EHRs and prevent potential medical disputes. Moreover, our RBAC enforces a forward revocation mechanism. A revoked user cannot access to the future EHRs even if his/her previous role satisfies the access policy. We analyse the security and efficiency of our RBAC, showing that it is an practical solution to secure EHRs. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
