Hi all.This has been an interesting discussion thread.  Here are my 2 cents worth
Generally when data are de-identified, there is a loss of detail as there are various suppression technics that are used. A general overview can be found at https://www.ihsn.org/sites/default/files/resources/IHSN-WP005.pdf
Since that paper was written, there has been progress made in software to assist in the creation of anonymous files and an increasing use of remote dat access.  One example is from Statistics Canada https://www.statcan.gc.ca/eng/rtra/rtra
A third approach that is used is to establish data enclaves.  An example:  https://www.statcan.gc.ca/eng/microdata/data-centres 
Someday, we hope to reach a state where data will not have to leave home but rather will be "visited" by researchers.  
Each approach has pros and cons. 

Cheers, Ernie+1-613-290-2804
