| You are probably thinking of rule-based personalization, where someone decides in advance what's appropriate for you when you are in an area. What Nathan Eagle does is use past behavior of others and you to predict what you will do in a new location. If the system can't store the location of others, then it has no "model" to figure out what you will do when behaving similarly. Furthermore, if it can't save your past behavior, a system cannot build a model of your personality to leverage and the phone must transmit your whole behavioral history to the system every time it wants to predict for you. In a sense, this is even more risky because now you must worry about things intercepting the data. Europe, as far as I know, has done very little research in this area of predictive geographic modeling. I think it is because of this law. It is fine to make such a decision, but it has tradeoffs that people may have failed to consider. And it is a truism that Europe is especially sensitive to privacy issues in the area of business (not so much if Big Brother--aka the government--is watching). The US is much more permissive to corporations, and there are downsides to that as well. Dan R.
