The two have explained their discovery during one of the conferences of the Where 2.0 event. Researchers have ensured that all iPhone models perform this registration (application).
Apple terminals store the points through which their users pass, marking the exact length and length. This record remains hidden, but it is not protected or encrypted. In fact, the two researchers say that every time the phone connects with a computer, the file is shared. The information is not protected and by sharing it is totally exposed.
In statements collected by the Guardian newspaper, the researchers comment that they have not located a record of this type in terminals of other brands. With the data of the registry you can make a tracking map of the users, which could be a serious violation of their privacy.
Apple has not ruled on the issue, although according to The Guardian, the agreement that authorizes users to use iTunes contemplates the possibility of storing this type of data.
