Data is everywhere. It is being collected in almost every industry and in every layer of government. While there have been many discussions about the automated decision making algorithms, there has not been enough investigation into the data itself, how it is collected, transferred in and out of the public sector, used in governance, and stored. As more data systems are built in all areas of life, we want to take a step back to explore the ever-growing collection and use of data and its hidden impacts. The symposium will explore these issues from a variety of perspectives, including those of lawyers, academics, journalists, media experts, political scientists, philosophers, industry experts, technologists, and policy makers.
