Allowing data, particularly big data, to be shared between the public and private sectors has significant benefits. These include improved public services, transparency and citizen engagement – not to mention the potential for driving economic opportunities and business innovation. And the private sector has an important role to play, not only in leveraging the value of government open data, but in making some of its own data open or available to the public sector through collaboration. Many of these data-driven public-private partnerships have already proven successful. For instance, Uber released their data on traffic to aid transportation planners and city officials; Statistics Canada has partnered with smart meter companies to access electricity consumption data to better understand consumption patterns; and the telecommunications company, Airtel, shared data with the World Health Organization to help combat tuberculosis in India…Yet with great potential comes great risk. Big data sharing raises pressing questions about security, privacy and consent. These questions have become even more salient in recent years, as we’ve learned more about how our data has been handled by technology companies and others.
