Abstract:
Privacy of personal location information is becoming an increasingly
important issue. This talk discusses some of the challenges of providing
location privacy whilst at the same permitting location-based services
to function. Most methods of enabling location privacy in the literature
use access control; this talk introduces the mix zone model which takes
a different approach, enabling location privacy through anonymisation. A
mathematical model is developed to provide a quantitative measure of
anonymity and a method of providing direct feedback to the user is
discussed.
