Health Records Privacy Issues in Cloud Computing

Personal health record service avail patients to store and dominate their healthy information data through the cloud. Many users like medical doctors, health care providers and family members can access this data through the internet. However, there are privacy issues related to data exposure and data breaches, causing risk to patients' lives. Encryption techniques like public key encryption are applied but they are not efficient and very complex, in addition to scalability problems. In this paper, various multi-authority attributes based on encryption solutions features are discussed that able to protect the privacy for E-Health records after divide it to private and public domains. © 2018 IEEE.
