In this talk I will describe two examples of this work. First, I'll present Keypad, an auditing file system for theft- and loss-prone mobile devices that permits users to track and control accesses on their mobile data, even after a device has been stolen.\n Second, I'll describe Vanish, a global-scale distributed-trust system that allows users to cause all copies of desired Web data objects, online or offline, to simultaneously self destruct at a specified time. A common thread of these efforts is the integration of systems and crypto techniques to solve new problems in data management brought on by technological change.\n Biography: Roxana Geambasu is a doctoral candidate in the Department of Computer Science & Engineering at the University of Washington. Her interests span broad areas of systems research, including cloud and mobile computing, operating systems, file systems, and databases, with a focus on security and privacy. She received her B.S. in Computer Science from the Polytechnic University of Bucharest in 2005 and was the recipient of the first Google Fellowship in Cloud Computing in 2009.\n \n Host: Prof. Ramesh Govindan, USC DTSTART:20110215T153000 LOCATION:SSL 150 URL;VALUE=URI: DTEND:20110215T170000 END:VEVENT END:VCALENDAR
