It’s a bit weird but true. The main thing is that whenever you take your iPhone, iPad with you, your device is connected to your iTunes via GPS, when you connect your device with iTunes it copies a file of GPS into the Operating System’s folder and after that when your PC gets connected to the web it sends the IMEI of your device to satellite and you get caught !!! We got to thank to Pete Warden and Alasdair Allan who researched on it and came to the result while they have also released an application to know your recorded moments.
O’Reilly’s were the one who caught both of them for an interview, below is the interview:
What information is being recorded?
All iPhones appear to log your location to a file called “consolidated.db.” This contains latitude-longitude coordinates along with a timestamp. The coordinates aren’t always exact, but they are pretty detailed. There can be tens of thousands of data points in this file, and it appears the collection started with iOS 4, so there’s typically around a year’s worth of information at this point. Our best guess is that the location is determined by cell-tower triangulation, and the timing of the recording is erratic, with a widely varying frequency of updates that may be triggered by traveling between cells or activity on the phone itself.
Who has access to this data?
Don’t panic. As we discuss in the video, there’s no immediate harm that would seem to come from the availability of this data. Nor is there evidence to suggest this data is leaving your custody. But why this data is stored and how Apple intends to use it — or not — are important questions that need to be explored.
What are the implications of this location data?
The cell phone companies have always had this data, but it takes a court order to access it. Now this information is sitting in plain view, unprotected from the world. Beyond this, there is even more data that we have yet to look at in depth.
For example, in my own case I (Alasdair) discovered a list of hundreds of thousands of wireless access points that my iPhone has been in range of during the last year.
How can you look at your own data?
We have built an application that helps you look at your own data. It’s available at petewarden.github.com/iPhoneTracker along with the source code and deeper technical information.
What can you do about this?
An immediate step you can take is to encrypt your backups through iTunes (click on your device within iTunes and then check “Encrypt iPhone Backup” under the “Options” area).
