I think this is an odd takeaway from this article after reading the rest of it:
“In other words, as urban planners, tech companies, and governments collect and share data, we now know that “it’s anonymized” is never a guarantee of privacy. And as they dig deep into the data we generate, cities and citizens need to demand that this data can never be reidentified.”
The MIT study just showed how ridiculously easy it is to take a couple of anonymous data sets, combine them together, and turn them into anything but anonymous. I think demanding that it be made “more anonymous” misses the point. The only way to guarantee that is to not collect it, or share it, in the first place.
Where are the calls for that?
