MuoviMe: Secure Access to Sustainable Mobility Services in Smart City

Sustainable mobility is a key objective for many Smart Cities. In this paper, we present an application for sustainable mobility that aims at encouraging citizens to use low-impact vehicles instead of private cars. Through a partnership between the University Messina and the Municipality of the Messina city (Italy), we developed MuoviME, a digital application to assign citizens electric bikes, free of charge for a limited period of time. The key issue we addressed in the development of such an application is security, both in terms of secure authentication of citizens that access the service and tracking of the whole assignment process, from the user's bicycle request to its restitution. To achieve this goal, we implemented a solution for the physical recognition of the user based on two-factor authentication (2FA) and Blockchain technology. This paper summarizes the secure by design approach, implementation details, and some experimental results on the service efficiency.
