Enhanced Security Level for Sensitive Medical Data Transmitted through Visible Light

The recent events regarding worldwide human health sped up research efforts and resulted in the tremendous development of new technologies and applications. The last decade proved that new technologies find a proper place in worldwide human health and wellbeing, therefore the security of data during wireless transmission in medical facilities and for medical devices has become a research area of considerable importance. To provide enhanced security using conventional visible light wireless communication, we propose in this paper a novel communication protocol based on asymmetric encryption with a private key. We base the wireless communication protocol described in this work on a data encryption method using block chipers, and we propose it for medical facilities and devices with visible light transmission technology embedded. The asymmetric encryption with a private key algorithm, as part of a transmission protocol, aim to assure the security of sensitive medical data during wireless communication.
