Uma arquitetura segura baseada na computação ubíqua para recuperação de registros médicos

Abstract

Medical Records systems are important tools for easy access and maintenance of patient data, such as its history of hospitalizations and medical exams. Currently, physicians, nurses and technicians need a quick and secure access to medical records, avoiding bureaucracy and uncertainties in the process of recovery of this information. The ubiquitous and pervasive computing can help in overcoming these challenges, however the problem of impersonation devices should be handled carefully to be no compromise private information or tampering in any kind of records. In order to mitigate this problem, this paper presents a secure architecture based on ubiquitous and pervasive computing to the restoration and maintenance of medical records. This architecture depends on the Near Field Communication technology (NFC). Thus, an authentication mechanism is designed to ensure the authenticity of the devices involved. The architecture is evaluated in Hospital de Caridade de Jaguari (HCJ). The results of analysis and validation shows that the mechanism is effective and promising, establishing mutual authentication. In addition, other important security properties are achieved, as the anti-replay protection and anti-tracking.
