Personal data is a key building block for innovative smart city services. However, as seen in cases like the Sidewalk Labs’ effort in Toronto, concerns about governance and unclear usage of personal data can create pushback from the public and erode trust. In response, cities around the world are adopting approaches to personal data management that put people in control of their data. This human-centric approach both protects and empowers residents, whilst encouraging the growth of data-driven services.
