Electronic health record (EHR) systems play a relevant role in hospital daily activities. They support the access of patient data, such as medication delivery and history of hospitalizations. Currently, it is essential to provide easy and secure access to medical records by hospital staff. Pervasive and ubiquitous computing can lead to a better way to manage EHR systems. In this scenario, one of the greatest research challenges is to ensure device authentication avoiding its impersonation. The main contribution of this work is to carry out an extended experimental evaluation of a secure architecture based on ubiquitous computing for medical records retrieval and maintenance to demonstrate its feasibility through of experiments in laboratory and hospital scenarios. For evaluation, this article implements a prototype that performs the medication delivery procedure. Experimental results indicate the system functionality, usability with a decreasing user learning curve, and no significant overhead in terms of communication delay.

2. Literature Review

Recently, several works have highlighted the NFC technology as a prominent tool to extend the ubiquitous computing and communication. NFC is a data communication technology that uses radio waves at high frequency of 13.56 MHz. The key to communication is proximate identification, usually limited to about 10cm (Aziza, 2010; Coskun et al., 2013; Page, 2016; Want, 2011). However, the short range of NFC transceiver does not totally avoid security attacks, as impersonation of devices.
