An ECC-based secure EMR transmission system with data leakage prevention scheme

Abstract

In this paper, we propose a secure electronic medical record (EMR) service system, named the ECC-based Secure EMR Transmission System (ESEMRT for short) which employs a cloud database, an elliptic curve cryptography (ECC) integration unit, a smart card, and portable devices to provide users with a secure environment for EMR transmission. The ECC integration unit, which integrates a 256-bit ECC chip, wireless transceiver, smart card reader, and USB interface for fast computing and reducing the communication load of a portable device, can securely protect the EMRs when these EMRs are delivered between the cloud database and the portable device so as to enhance their transmission security and the patient care quality. Besides, the data leakage prevention scheme is also implemented in the ESEMRT to avoid illegal duplication. Our simulation shows that the proposed system can provide a higher security level and reduce portable devices’ hardware resource requirements.
