A Systematic Review of Personal Information Sharing in Smart Cities: Risks, Impacts, and Controls

Abstract

AbstractSmart cities aim to deliver smart services that rely on emerging technologies to their users. In order for users to get the provided services, they need to share their personal information with different parties. However, sharing personal information in smart cities may impact the privacy of that information. Thus, there is a need to address privacy risks relevant to sharing personal information in smart cities. This study aims to address this issue by conducting a systematic literature review (SLR) to identify and extract privacy risks, impacts, and existing controls associated with sharing personal information, considering elements involved and interacting during the sharing activity in smart cities. A set of 83 selected studies in both academic and industry fields were reviewed, and the results were categorised into three main groups: privacy risks, impacts, and controls. Moreover, the implications and future research directions were also reported. The proposed privacy risk taxonomy will provide a much-needed foundation for the industry and research community, intending to research and evaluate privacy risk frameworks and design solutions for sharing personal information in smart cities.
