Towards a Holistic Privacy Preserving Approach in a Smart City Environment

Nowadays, the adoption of smart city technologies in different contexts has improved individual’s quality of life. Besides, Cities and communities generate huge amount of data through a vast and growing network of connected technologies, cloud infrastructure, big data and internet of things applications. However, the use of these technologies raises several concerns regarding data privacy. Particularly, with the increasing number of actors (service providers, government, citizens….) involved in smart city environment, it becomes harder to protect citizen’s private information. Moreover, citizens become passive actors regarding the use, disclosure and exchange of their sensitive data. Motivated by this, we compare some of privacy preserving solutions suggested in smart cities ecosystems. From this study, we deduct that the major proposed works in the literature do not consider the concerns of the different stakeholders, especially the compliance with relevant privacy regulations. Thus, we make a comparison between the most known privacy laws followed by a case study applied in smart health sector.
