ABE Based Online Personal Health Record System Using Cloud Computing

Abstract

:Online PHR system enables the user's to share the personal health records via the internet. PHRs grant patients access to a wide range of health information sources. In this system PHR owner is responsible for create, manage and control the personal health data in a centralized place using the web. Due to the high cost of building and maintaining a specialized data centers the PHRs are outsourced to store at a third party such as cloud servers. Cloud computing servers provides the platform for storage of data. The confidentiality of the PHR is the major problem when patients use commercial cloud servers to store their records because it can be view by everyone. The third party servers are semi-trusted servers and hence it is important to provide encryption before outsource the PHR to the third party servers, which ensures the patient's full control over their PHR. The Attribute Based Encryption(ABE) technique is used to encrypts patient's health records and also provides break glass access under emergency scenarios. The security problems of break glass access can be resolved by using hardware token security.
