iPhone and iPad store motion profiles

Apple devices remember when a user was where. Two programmers have found the file and built an application that can view all their supplies data

The fact that smartphones are tracking bugs, like the Chaos Computer Club calls it, many users might already be clear. After all, it is not unlikely that a device that constantly knows his whereabouts to this notice as well. However, it creates an uneasy feeling when discoveries like the following are known: iPhone and iPad save all the recorded position data and transmit it updated iTunes to the user's computer as soon as the smartphone to be his or tablet computer with the software and comparing. It reported that two programmers Alasdair Allan and Pete Warden currently in the conference Where 2.0 in Santa Clara .

The two have iPhone application called Tracker written a with any Apple users to read data stored on it and the position on a map can represent.

The data are similar to those that will help Germany in connection with the retention of heated political discussions. Save for mobile service provider, from where and when each mobile phone to access the wireless network. They do this among other things, the settlement of the costs for the customer, usually up to 90 days. The EU demands even at least a half year period of storage, so that the police can use in certain cases, the data for investigations. Privacy advocates consider this a non-event-total surveillance. To illustrate the problem, ONLINE TIME visualized in an interactive graphic communication data of the Green Party politician Malte Spitz.
What iPhone and iPad record is, these so-called stock data are quite similar. The devices store longitude and latitude based on the position of mobile radio cells. "This is less accurate than GPS, but probably consumed less power," Allan writes on his website. In addition, the file contains a time stamp for each position in seconds, from 1 January 2001.

How often places the device that data is different, but probably it happens every time you login to a new cell. According to Allan and Warden in this capacity until the new operating system iOS 4 included, earlier versions did not store the data. If in doubt is recorded for about a year where someone was staying.

The data is not encrypted, but are before in an XML format, reported the two programmers. This also means that everyone who has access to the device or the computer with which it was synchronized, they can see. For example, partners or friends. Apple however does not seem to get the data, at least say Allan and Warden, that they had found no evidence that the file is sent to Apple.

But why this information is ever stored? A statement from Apple gives it to so far not. Allan and Warden speculate that Apple is planning any future applications, to build. However, they are sure that the storage is not a coincidence - after all, the file would be updated specifically for each synchronization and transferred to new devices.
