*Event title:* Data usage by Big Government: What we are doing, what can be done and the privacy concerns for the next few years. *Event description:* We are going to discuss one major point here: what are the limits between the data gathering by the governments to develop public policies and the privacy of the citizens. To illustrate the discussions, we are going to briefly describe two big data project in Brazil: the Supremo em Números (Supreme Court in Numbers) and the Big Data Team - PENSA of the Rio de Janeiro City Hall. The first one is a typical civic hacking project, developed in the academia, to capture and analyze more than 1.2 million cases from the Brazilian Supreme Court website. We are going to see how those data were used to improve the quality of the public services and the consequent results already achieved, like a proposal of amendment of the Brazilian Constitution. The second case we are going to present is the Big Data Team - PENSA, of the Rio de Janeiro City Hall, and the public policies which are being developed with the gathering and the analysis of large data sets, like Waze reports, buses' GPSs and Call Detail Records - CDRs from mobile phones, among others. Finally, considering what the governments are already doing and what can be done in the next few years, we are going to discuss what would be the ideal regulatory framework to, at the same same, allow a responsible data usage by the governments and how it could be done without affect the privacy of the citizens. *Speaker:* Pablo Cerdeira *Law professor at FGV DIREITO RIO.
