Development of SWIM Registry for Air Traffic Management with the Blockchain Support.

System Wide Information Management (SWIM) including SWIM Registry for Air Traffic Management (ATM) has been successfully developed and applied in Europe and United States. The most developing countries have just started to study the employment of SWIM concept, which its establishment is required prior to the development of SWIM Registry. In this paper, we introduce the experience of the development of SWIM Registry Brazil, which comprises the study of the architecture, components, services and data accessing. In order to encourage consumers and providers to participate in the SWIM community, we developed a prototype of SWIM Registry Demonstration for the Brazilian ATM society. We propose a model based on Blockchain for managing services currently provided by Brazilian ATM in order to certificate operations which are performed by consumers, authorities and involved stakeholders. The proposed model is expected to provide services for SWIM Registry with integrity, efficiency, security and authenticity, which are fundamental for the proper operation of Brazilian aviation system.
