11:00 – 12:00: Keynote Speech: TIME for Better Privacy

Alastair Beresford (University of Cambridge, UK)

ABSTRACT: The Transport Information Monitoring Environment (TIME) is an umbrella project at the University of Cambridge Computer Laboratory which is investigating how the use of computers, sensors and networks can improve transportation, with a particular focus on deploying prototypes in the city of Cambridge, England. Newer transportation schemes---such as congestion charging and pollution monitoring---often utilise mobile sensors attached to individuals or their vehicles. Therefore location information is a key component of data collection, yet this same location data often also contains private information. This talk will describe some of the privacy measures we have been developing as part of several TIME-related initiatives, ranging from improved sensing techniques and mobile sensor platforms, through to new pseudonym schemes and novel methods for controlling the disclosure of personal information.
