In NYU Tandon School of Engineering’s third, eagerly anticipated Sloan Cyber Security Lecture, Federal Trade Commissioner Julie Brill explores the expanding collection and use of Big Data in the marketplace, recognizing the challenges it presents for consumers and businesses–as well as for agencies like the Federal Trade Commission, responsible for safeguarding both. Commissioner Brill embraces the enormous benefits offered by Big Data analytics, but also believes it presents fundamental challenges to traditional notions of individual privacy. She encourages the highly decentralized community of Big Data purveyors to adopt practices that follow laws that already govern the way data can be used and calls for industry to engage in robust de-identification of consumer data. She concludes by taking us through her comprehensive initiative, “Reclaim Your Name,” to give consumers knowledge and tools to reassert control over their personal data.
