In any database whose fields have at least 4 meaningful ranges, 16 fields give 4.000.000.000 possibilities. Now I am on my iphone. As long as ranges are meaningful (i.e. they do divide the group in somewhat even parts), the individuating possibilities are HUGE. And fields do have usually many more than 4 ranges.

Anonymizing datasets is a weasel term.

The database is secure or it is not. As any database is quite likely insecure, we are doomed.

An anonymized version would be one where you have a tally for each value/category in each field, without any correlating table between the fields. Only store the histograms.

Well, yes, but then that is not what advertisers want... That is the thing.

Whenever a large enough database exists with individual data, we are doomed.
