Smartphones equipped with advanced positioning technology
continuously collect users' location information and make that information
easily accessible to third party app and/or library developers.
Users are becoming increasingly aware of the resultant privacy threats,
and demanding effective privacy preserving solutions that will allow them
to securely use location-based services. In addition, academic and industrial
communities are paying special attention to the development of
more friendly and socially-accepted approaches to location privacy. In
this work, we model, design and evaluate LP-Cache, a mobile platform
based service that protects locations by modifying the location resource
handling process. It applies caching technique to protect users' private
locations and establishes personalised location permission controls. We
define the design decisions and implementation requirements towards the
viability and feasibility of the model deployment. We also evaluate resources
and storage requirements in order to minimise the computational
and communication overheads. Empirical results of 2 months comparative
study show a 2.26% change in the network fingerprints at 34 distinct
places that required only 2.07% change in the overall cache storage. Both
these results demonstrate feasibility of the model.
