Is it possible to anonymously track someone's location via mobile apps?

Is it possible to anonymously track someone's location via mobile apps?

Assuming, of course, that the user consents and dow开发者_运维知识库nloads an app that can in the background?

iPhone OS 4 (coming "this summer") will allow you to run your app in the background, I believe that will allow you to keep track of the location.

The answer is both yes and no.

Yes, because Apple already supports this for MobileMe accounts, where you can track a registered iPhone through the "Find My iPhone" feature.

No, because you are not able to have an application run in the background on any current versions of the iPhone OS. It is possible that future versions will allow this, but not for any current versions.

So, Yes if you are Apple (which you are probably not) and no for the rest of us.

I guess the answer is yes, it's possible. Since you can share your location in various forms already, nothing is stopping a service to allow entry to the public.
