A data integrity and security approach for health care data in cloud environment

Abstract

Healthcare digitalization has turned out to be a significant paradigm in the advancement of medical sector. Resultant, there is production of huge volume of patient’s digital information. Moreover, storing and safeguarding such information tends to become a critical point of concern. The cloud technology assures to be an effective mechanism towards handling and distributing healthcare information by attending the concerns pertaining to data integrity, security and privacy. The significant benefits and accessibility offered by the cloud technology has immensely raised the storage of healthcare information. It’s highly important that the sensitive healthcare data residing in the cloud is completely secured amidst the healthcare providers and the cloud server. There has been a rising concern associated with secured data access within the cloud environment. That is, the cloud framework must assure a robust authentication control mechanism which allows the healthcare users to confidently share medical information across it. Towards accomplishing the same, a secured and light weight data access management system has been recommended that promises data Integrity and Security. Moreover, the proposed system offers the feature of authority control authorization and authentication mechanism for safeguarding the health-related data residing and circulating within the cloud. A CIAM (Customer identity and access management) helps in secured Data Access Control and OAuth 2.0 aids in providing right privilege with authorisation. Also, by the means of Progressive Attribute Based Encryption approach, sensitive medical information can be encrypted from the cloud storage in a secure manner. The proposed light weight framework yields in efficient, reliable and stable output within the cloud.
