The Dutch national office of statistics has tools intended to de-identify 'microdata' such that k-anonimity[1] is achieved called mu-argus[2] and tau-argus.

[1] A release of data is said to have the k-anonymity property if the information for each person contained in the release cannot be distinguished from at least k-1 individuals whose information also appear in the release. https://en.wikipedia.org/wiki/K-anonymity [2] https://research.cbs.nl/casc/mu.htm

This is really cool, and deserves a submission of its own, I'd say!
