A Cryptography Framework for Secure Electronic Health Record and Exchange

Now days, the medical domain adopted Electronic Health Record (EHR) for digitalizing patient records and also computerizing medical core processes to get instant access of the patient health information. The EHR promises the ability of exchanging health information for betterment of social life. Since the EHR goal involves fully inter accessible, patient centric and easy to use the systems, it demand security while storing, accessing and transmitting health information from one to another. This paper presents a secure cryptography framework for Health Information Exchange (HIE) and Health Information Record (HIR). In this paper, the proposed secure cryptography framework uses Secure Hash Algorithm-3 (SHA-3) as security technique. The SHA function is constructed using linear equation and modulo exponentiation techniques. Finally, the secure framework implemented for few medical transcripts and benchmark medical images.
