> Location information cannot be effectively anonymized without basically nullifying its utility. I was under the impression that properly anonymizing location data includes aggregating a sufficient amount of individuals and the radius of this aggregation of course changes based on the population density in a given area. In with anonymized location data we can only draw conclusions on a populace and not an individual, which is still very useful. Of course, I generally agree with you. In most cases it won't be done properly and just replacing PI with the same "anonymous" id on a set of location data points of an individual achieves next to nothing.
