The two programmers, Alasdair Allan and Pete Warden, presented their discovery at a conference in San Francisco.
The file called “consolidated.db” keeps a record of GPS data on Apple’s 3G systems and updates regularly depending on the user’s location, according to the New York Times.
The information stored on the phone is sent to the iTunes app as well when the user synchronizes an iPhone or an iPad 3G.
“The presence of this data on your iPhone, your iPad, and your backups has security and privacy implications,” said Alasdair Allan, one of the programmers who have found the file.
The two developers have contacted Apple’s product security team but said they had not yet had a response.
Pete Warden said he created an application that allows users to see data collected about them by the IOS device. After downloading, which can be free, the application displays the information that the iPhone has recorded and stored about previous movements.
Both developers say the current storing of user information shouldn’t be a reason to panic, but it’s not yet know how Apple intends to use the stored data.
Information about the location of mobile phone users have always been stored, but could be available only through a court order. The possibility of viewing the information on IOS devices could cause them to become available to anyone with access to the phone.
In the following video, Allan and Warden discuss how the file was discovered and examine the data contained in the file.
