Secure and Privacy Preserving Mobile Healthcare Data Exchange Using Cloud Service

Healthcare using Mobile devices and Cloud Computing is an emergent topic of interest in both industry and research. Though ubiquity of mobile devices and availability of e-Health record plays an important role to enhance health care quality and services, it introduces several challenges too such as, limited power of mobile devices, privacy and anonymity of patient data, the reliability of end user, interoperability and availability of e-Health records, etc. Under HIPAA regulations, healthcare data needs to be secured from unsolicited disclosure when sharing among multiple medical service providers. In this paper, we focus on exchanging healthcare data among doctor and patient's healthcare service providers. We develop an android mobile application and a Cloud service to exchange patient's data among authorized users in a secure and privacy-preserving manner. The cloud service that we developed performs cryptographic computations, communicates with mobile application and also overcomes the limitations of mobile devices. We evaluate our proposed solution using real-world data set. The performance analysis proves the efficiency of our application. Privacy analysis of our proposed solution depicts that our system is secure and protects the privacy of healthcare data.
