Privacy of Health Information in Telemedicine on Private Cloud

Vanishree Arun, Padma SK, Shyam V

Telemedicine involves many people at many levels with potential access to health records or medical data or the health details of a particular person. Privacy and security have always been an issue in telemedicine. In order to overcome this problem, cloud has been adopted to store and securely access data. Cloud offers a way to allow medical data and images to be transferred from patient to medical clinicians providing security. But individual patient data is not provided with privacy when it is outsourced to public cloud. In this paper, using a case study of screening the masses for early detection of non-communicable diseases at Sri Kshetra Suttur, privacy is built into telemedicine or mobile health care system with the help of the private cloud. Efficient key generation, Encryption, Decryption and analysis of health data misuse by authenticating authorized Clinicians to access patient records using Paillier Cryptosystem and Searchable Symmetric Encryption are some of the salient features introduced in this paper.
