The Rise of the Smart City
The information revolution is changing the way cities are run - and the lives of its residents. Cities have a way to go before they can be considered geniuses. But they’re getting smart pretty fast.
In just the past few years, mayors and other officials in cities across the country have begun to draw on 【1】 - about income, traffic, fires, illnesses, parking tickets and more - to handle many of the problems of urban life. Whether it’s making it easier for residents to find parking places, or giving smoke alarms to the households that are most likely to suffer fatal fires, big - data technologies are beginning to 【2】 the way cities work.

In theory, anyway. Widespread use of sensors and video can also present privacy risks unless 【10】 are taken. The technology “is forcing cities to face questions of privacy that they haven’t had to face before,” says Ben Green, a fellow at Harvard’s Berkman Klein Center for Internet and Society and lead author of a recent report on open-data privacy.
