Pseudonymization approach in a health IOT system to strengthen security and privacy results from OCARIOT project

Abstract

Regarding security and privacy in Internet of Things (IoT), especially in a digital health system, is necessary to guarantee that user rights are respected. This requires an approach that considers security-in-depth strategy established on risk-based results, actors, their privacy and the entire ecosystem, including the applications and platform. This paper presents an approach to strengthen the security and privacy aspects, using different security layers based on cryptographic, pseudonymization and anonymization technics to protect the processed, stored and transmitted data. The approach present at this paper was developed and applied in a digital health platform in the Project OCARIoT.
