Apple collecting info on where you have been :-

Seems to be becoming more and more prevalent, I wonder if people realise quite how much data is collected by the likes of google and apple.

I find the techniques described in this article brilliant and fascinating.  I find the implications somewhat threatening...

 

Discuss.

 

Very scary. But I would think it would also depend on very good routing by the sources ISP. For instance, where do they route you out to the Internet backbone from their infrastructure.

 

One of the tools we use for clients for testing bandwidth is www.speedtest.net. The interesting thing about this site is it uses various techniques to find the "closest" server to you to test, and you can see an approximation of where "you" are in the map. I have one client here that is on a new range of IP's that Bell Canada just got. When we go to speedtest, it thinks the site is on the northern most point of Hudson Bay, in Nunavut. The closest server to test is in the Northwest Territories... Huh?? Not even close...  Of course for a few days last week, it also thought we were in Manitoba... And I do not doubt the tool as it works pretty flawlessly most of the time for us. I more doubt the ability of Bell to build a decent infrastructure...

 

This all seems to be based on the routing within the ISP's infrastructure. The better the routing, the more accurately people can pin you down.

 

Guess it is time to start using my VPN Proxy more often. ;)
