Abstract

The proliferation of smart devices in the Internet of Things has given rise to the Smart City. Despite improvements in the service quality, the Smart City suffers from potential privacy threats. Adversaries can take advantage of Smart Cities and launch various attacks to learn sensitive information about individuals, especially through social links and locations. Motivated by this, we comprehensively survey current attacks and existing protection schemes. In addition, we place special focus on social link privacy and location privacy, which are two primary privacy issues under the scenario of the Smart City. Built upon the survey, we further propose some possible promising future research directions to pave the way for potential privacy protection methods.

    A further improvement oriented toward a big data perspective consists in nourishing the model with a dynamic database, able to track real-time values of actual prices, travel durations, and departure and arrival times, therefore making the model as realistic as possible. This could allow overcoming the limited attention reserved by decision makers of private and public transportation organisations to users’ centrality in designing and implementing smart mobility services (Qu et al., 2019; Papa and Lauwers, 2015). From the scenarios depicted, it is possible to demonstrate that, due to the broad dissemination of digital and smart technologies, the mobility of people is increasingly configurable as a data driven process (Badii et al., 2019; Qiu et al., 2019) impacting companies’ competitiveness and territories’ socio-economic and environmental goals (Faulin et al., 2019).
