Google Maps mobile with "My Location": Privacy Loophole

I had quoted earlier from the Google Help page on Google Maps mobile's My Location feature, that it was totally private and Google did not record or store any person's or phone's identifiable information, tied to a particular location.

The New York Times' Bits blog has this to say about a loop-hole when you use Google Maps mobile which has the My Location feature to do a search for say a close-by business:

The payoff for Google from building out its mapping service is to get people to conduct searches from their cellphones. This is a nice feature. Push a button on the map software, type “Starbucks” and it will display a map of the closest source of a latte fix, based on the cell tower or GPS data. The catch, is that this query, with your location, is entered in Google’s log files along with your phone’s unique ID.

So, the "My Location" feature itself will not uniquely identify you. But doing a search will uniquely identify your phone, and tie it to a location. That is a damned good catch by the Bits blog, I say!

Needless to say, if Google wants, it can tie your uniquely identifiable phone to the uniquely identifiable Google login ID you might use on the phone. I am not saying that Google does that. I am saying that Google can do that. Perhaps, under pressure from a subpoena or the Chinese government?

Google Maps for Mobile: Now location aware without GPS!

Google Maps for mobile phones has announced a new feature called My Location (still in beta). This feature brings an approximate location information to Google Maps on your mobile phone, even if the phone does not have GPS functionality. Google uses cell tower identification to provide the location information. So, a lot depends on the number of cell towers at the location. The accuracy could be off by as much as a couple of kilometers (over one-and-a-quarter mile).

Here's a video from Google explaining how this feature works:


The My Location feature is available on a few selected devices right now.

Regarding the all important question that lot of people would have, this is what Google Help says:

Will Google always know where I am if I use My Location (beta)?

No, Google does not know who you are when you use Google Maps for mobile. All handsets are anonymous. When you use our product, we do not collect personal information like your username or phone number, so we do not know who owns or is using the handset. Therefore, when we identify approximate location [as part of the My Location feature], all we can determine is the approximate location of the handset. This location information is also only in our system when a user has opted-in to the My Location (beta) service. If the My Location (beta) feature is disabled, we will not continue to send radio information back to Google servers to determine your handset's approximate location while you use Google Maps for mobile.

Good job answering that question upfront!


Android Update: This feature is sure to be available in future versions of Android (if it is not already). This means, any Android application which needs your location information would work, kind of, even if your Android cell phone does not have GPS! Wow!
