ANALYSIS OF TIME BOUND COLLABORATIVE ACCESS CONTROL DELEGATION MODEL IN ELECTRONIC HEALTH RECORDS

Electronic Health Records (EHR) is the digital record shared across multiple users like hospital, personal physicians, researchers, insurance companies and many. Such a scenario of data sharing attracts much attention towards security and privacy of their own medical records. These data are patient centric and patients are very much concerned towards the limitations in sharing of their own medical records. We present a time bound combined access control model which provides concerns on spatial dimensions and time constraints to concern over temporal dimensions. This model aims in providing privacy since dynamic key creation and distribution is included based on the time constraint using a new key assignment scheme suitable for hierarchical systems. The research focus will be on insisting the importance of the role of Delegation and Access Control in Health care. Time Bound Access Control is to be proposed and concentrated much on developing and implementing algorithms related to combining various access controls techniques as a time bound delegation model. Combining privacy policy through an analyzer will control the access of data, which gives the privacy of the data.
