Trying to find cases that show the different techniques of data de-identification.
Professor Latanya Sweeney http://latanyasweeney.org/ talked about how she managed to re-identify “de-identified” data during the AINow event last week (Artificial Intelligence Now) at NYU. Perhaps you could look for things written by her. Here is one:
De-anonymizing South Korean Resident Registration Numbers Shared in Prescription Data: http://techscience.org/a/2015092901/
Solomon Barocas is a relevant scholar on big data and ethics, he might mention some cases that then you could research further.
Also Professor Foster Provost at NYU Stern could be a good person to ask. Happy to make the introduction.
