Privacy-Conserved Health Care Information System with Efficient Cloud Security

Monitoring and advising patients via mobile health care system is the current trend in medical field that acts as a life saver due to its availability at anytime and anywhere. This e-healthcare system requires patient-s private data to be available at cloud, outsourced data storage. This situation faces privacy issues. Hence the proposed approach focus on providing a private cloud for mobile users to ensure less cost, effective and secure storage. The data keyed in the mobile is transferred to private cloud, which in turn is processed and again transferred to public cloud. The sensitivity of the outsourced cloud data is maintained using Attribute based Encryption technique which restricts data access based on encrypt/decrypt of data with its access structures. The data privacy is ensured by PRF based key management and secure indexing methodologies. Personal Health records view ability access control to the actual data owner is the core idea of this project. The project segregates the access users in to Public Domain Users and Private Domain users.
