Abstract
Currently, health information systems are decentralised and hyperconnected to third-party data sources and systems. For their proper use, they require adequate security measures to verify the validity of information, thus avoiding potential harm to patients using erroneous, corrupt or altered data. These systems must be able to avoid vulnerabilities to decentralisation, prevent record modification and data integrity problems, and facilitate fast and efficient verification operations, since it is very important that security mechanisms must not hinder the operation of these systems on which human lives depend. In this paper, we propose a decentralised registry system for healthcare environments based on Blockchain technology. This register can provide the same security as transaction registers in distributed databases, but allows for load balancing as it is a decentralised system, thus facilitating fast and efficient operations, and provides Blockchain mechanisms to maintain the integrity of the validation register.
