We are entering a cyber world where millions of sensors continuously collect data. From the ocean bottom to deep space, scientists are monitoring environments at unprecedented scales. On a more personal level, implanted medical devices can now monitor our well-being and "smart chips" embedded in passports, IDs and transit cards can track our comings and goings. Massive, ubiquitous databanks offer promise of great benefits but also dangers. How do we manage this data onslaught wisely? How do we guard our privacy and ensure our safety? UW scientists are asking these questions and blazing trails on the latest frontiers of cybersecurity. From the Series:Engineering Lecture Series 2009: Engineering Xtreme Challenges
