Proficient Sharing of Personal Health Reports in Cloud

Brindha Kundavaran, G. Tagore Sai Prasad

A personal health report, or PHR, is a health report where health data and information cognate to the care of a patient is maintained by the patient. PHRs have the potential to avail analyze an individual’s health profile and identify health threats and amendment opportunities predicated on an analysis of drug interaction, current best medical practices, gaps in current medical care plans, and identification of medical errors. Hence it is an emerging patientcentric model of health information exchange, which is often outsourced to be stored at a third party, such as cloud providers. To have patients control it is very consequential to encrypt them afore outsourcing. The critical issues such as privacy, key management, flexible access and efficient utilizer revocation must be addressed. We utilize Attribute Predicated Encryption (ABE) to encrypt the PHR data, so that patients can sanction access not only by personal users, but withal sundry users from public domains with different professional roles, qualifications, and affiliationsthus enabling fine-grained and scalable data access control. The patient-centric framework provides a high degree of patient privacy by utilizing Attribute –Based Encryption techniques. The users in the PHR system are divided into multiple security domains that greatly reduce the key management intricacy for owners and users. This scheme additionally enables dynamic modification of access policies or files attributes, efficient on demand utilizer revocation and break glass access under emergency scenarios
