Laboratory for Analysis and Architecture of Systems
The approach we favor is to reduce location accuracy to reach an acceptable tradeoff between the utility of location-sensitive tasks and privacy protection. Some cryptographic techniques (e.g., secure multiparty computation) can also compute a global result depending on a large number of people without disclosing any information on particular individuals.
To this aim we develop a toolkit to evaluate the trade-off between location accuracy and privacy. In this toolkit, one can import new attacks algorithm and new sanitization techniques, in order to evaluate this trade-off.
