Approximately optimal auctions for selling privacy when costs are correlated with data
Lisa Fleischer, Yu-Han Lyu · 2012
We consider a scenario in which a database stores sensitive data of users and an analyst wants to estimate statistics of the data. The users may suffer a cost when their data are used in which case they should be compensated. The analyst wishes to get an accurate estimate, while the users want to maximize their utility. We want to design a mechanism that can estimate statistics accurately without compromising users' privacy.
