Readers who are interested in the Data Privacy field may find our new paper (Perry, Matloff, Tendick) of interest, https://tdp.cat/issues21/tdp.a478a22.pdf….

There we introduce a new method that we call RWN, Randomization within Neighborhoods. We present a bit of supporting theory and do some empirical evaluation. We also present a qualitative comparison to other major methods, including Differential Privacy.

An R package is in development (let me know if you wish to use the R code for now).
