Blockchain in EU e-health - blocked by the barrier of data protection?

Abstract

Compliance with data protection requirements is always a tricky business and even more intricate when it comes to cutting-edge technologies such as distributed ledger technology (DLT), better known as Block Chain Technology (BCT). These difficulties increase even more when the personal data concerned is accorded a special level of protection, as is the case with health data. The following article aims to describe and analyze the legal issues associated with this scenario. The focus here is on the European Union's (EU) General Data Protection Regulation (GDPR) 1, which took effect on May 25, 2018. Furthermore, the functionality of BCT and its possible fields of application in healthcare will be outlined.
