In these mechanisms, privacy is treated separately from the truthfulness; it is not incorporated in players{\textquoteright} utility functions (and doing so has been shown to lead to non-truthfulness in some cases). In this work, we propose a new, general way of modelling privacy in players{\textquoteright} utility functions. Specifically, we only assume that if an outcome o has the property that any report of player i would have led to o with approximately the same probability, then o has small privacy cost to player i. We give three mechanisms that are truthful with respect to our modelling of privacy: for an election between two candidates, for a discrete version of the facility location problem, and for a general social choice problem with discrete utilities (via a VCG-like mechanism). As the number n of players increases, the social welfare achieved by our mechanisms approaches optimal (as a fraction of n).}, isbn = {978-1-4503-1962-1}, doi = {10.1145/2482540.2482549}, url = {http://dx.doi.org/10.1145/2482540.2482549}, author = {Yiling Chen and Stephen Chong and Ian A.
