Why not? It's not hard to set up streaming filters that count how many people visit a certain mall in realtime without ever persisting the raw location stream.

But when the data you have is detailed logs of individual movements, second by second, meter by meter - stepping down to "number of unique IMEIs in a 100 square km area" is moving to "highly aggregated data". If that is what is seen as anonymization, the yeah. But then you've pretty much reduced a dataset to information that answers a specific question. Typically anonymization is (AFIK/IMNHO) taken to mean taka a dataset that can answer some questions, and transform it to a dataset that can still answer some questions we haven't come up with, but avoids answering questions that lead to identifying individuals. Eg: the problem with the NYC taxi driver data: http://arstechnica.com/tech-policy/2014/06/poorly-anonymized-logs-reveal-nyc-cab-drivers-detailed-whereabouts/ http://arstechnica.com/tech-policy/2014/06/poorly-anonymized...
