Workshop scope

Developments in mobile and surveying technologies over the past decade have enabled the collection of Individual­level geographic information at unprecedented scale. While this large pool of information is extremely valuable to answer scientific questions about human behavior and interaction, privacy intrusion is an imminent risk when detailed individual travel patterns are used for commercial purposes such as customer profiling, or even for political persecution. The GeoPrivacy workshop will hence focus on discussing methods to protect individual’s privacy in geographic information collection and analysis.

Topics of Interest

Topics of interest for the workshop include, but are not limited to:

• Awareness
• Perception of privacy
• Obfuscation
• Methods of privacy­preserving anonymization
• Geo­credibility, trust and expertise
• The role of geoprivacy in policy decisions
• Location Based Services
• Online Geosocial Networks
• Geofencing
• Privacy implications of Big Data
• Sample, training and test datasets
• Privacy in near­field communication
• Abstraction of geo data for privacy preservation
• Analysis of anonymized datasets
• Privacy implications of public displays and signage
• Gamification and geogames

Workshop format

The workshop will be kicked off with an invited keynote (to be announced), followed by presentations of full papers (30 minutes) and extended abstracts (20 minutes). Each session will include plenty of time for questions and discussions to enable an interactive workshop. The afternoon will be dedicated to small breakout groups to work on focused topics that emerge from the presentations in the morning sessions. Such a highly interactive workshop format has great potential to spark a significant number of new ideas for research and future collaborations in the realm of GeoPrivacy.

Keynote Speaker

John Krumm : Where Do You Want to Go Today? Challenges in Understanding Location

Location is important to the survival of every mobile creature for finding food, shelter, companions, and entertainment. The rise of mobile computing gives us opportunities to help people satisfy these needs using algorithms and data. Researchers have found a rich vein of questions and prospects around location, including how to sense location without exhausting a phone’s battery and how to use this location data to infer the mobile user’s context. They have used location data to predict destinations and paths, to create personalized driving routes, and to make road maps. Commercialization of these ideas leads to concerns about location privacy, which researchers have also addressed, producing some surprising results. This talk will describe new research on these topics in location and also suggest some promising new directions.

Bio: John Krumm graduated from Carnegie Mellon University in 1993 with a PhD in robotics and a thesis on texture analysis in images. He worked at the Robotics Center of Sandia National Laboratories in Albuquerque, New Mexico for the next four years. His main projects there were computer vision for object recognition for use in robots and vehicles. He has been at Microsoft Research in Redmond, Washington, USA since 1997, and is currently a principal researcher. He concentrates on location tracking of people and devices and on methods to use location data to benefit the user. He holds 50 U.S. patents. He was a PC chair for UbiComp 2007, ACM SIGSPATIAL 2013, and is a PC chair for the ACM SIGSPATIAL conference in 2014. He served on the editorial board of IEEE Pervasive Computing Magazine, and is currently a coeditor in chief for the Journal of Location Based Services.
