In a fully “smart” city, every movement an individual makes can be tracked. The data will reveal where she works, how she commutes, her shopping habits, places she visits and her proximity to other people. You could argue that this sort of tracking already exists via various apps and on social-media platforms, or is held by public-transport companies and e-commerce sites. The difference is that with a smart city this data will be centralized and easy to access. Given the value of this data, it’s conceivable that municipalities or private businesses that pay to create a smart city will seek to recoup their expenses by selling it.
By analyzing this information using data-science techniques, a company could learn not only the day-to-day routine of an individual but also his preferences, behavior and emotional state. Private companies could know more about people than they know about themselves.
For marketers, this is a dream come true. Imagine the scenario: A beverage company knows a particular individual’s Friday or Saturday night routine. The company knows what he drinks, when he drinks, who he drinks with and where he goes. It also knows how the weather affects what beverage the individual chooses and how changes in work patterns influence how much alcohol he consumes. By combining this information with the individual’s social-media profile, the company could send marketing messages to the person when he is most susceptible to the suggestion to buy a drink.
