PSIlence is a package for the R statistical language, that implements differentially private algorithms for releasing statistics while safeguarding the privacy of individuals in the raw data.
It provides the underlying algorithms for PSI (Ψ): a Private data Sharing Interface, a system created to enable researchers in the social sciences and other fields to share and explore privacy-sensitive datasets with the strong privacy protections of differential privacy (Project|Paper). However, it can be used by itself in any application needing code for differentially private mechanisms.
PSI and the PSIlence package have been developed by the Privacy Tools Project, an interdisciplinary research group at Harvard and MIT.
