Why Cops Love The iPhone
The Chicago Sun-Times published an article expanding on how police are using iPhones in their investigations.
• Every time an iPhone user closes out of the built-in mapping application, the phone snaps a screenshot and stores it. Savvy law-enforcement agents armed with search warrants can use those snapshots to see if a suspect is lying about whereabouts during a crime.
• iPhone photos are embedded with GEO tags and identifying information, meaning that photos posted online might not only include GPS coordinates of where the picture was taken, but also the serial number of the phone that took it.
• Even more information is stored by the applications themselves, including the user’s browser history. That data is meant in part to direct custom-tailored advertisements to the user, but experts said some of it could be useful to police.
Clearing out user histories isn’t enough to clean the device of that data, said John B. Minor, a member of the International Society of Forensic Computer Examiners.
Just as users can take and store a picture of their iPhone’s screen, the phone itself automatically shoots and stores hundreds of such images as people close out one application to use another.
“Those screen snapshots can contain images of e-mails or proof of activities that might be inculpatory or exculpatory,” Minor said.
• The keyboard cache logs everything that you type in to learn autocorrect so that it can correct a user’s typing mistakes. Apple doesn’t store that cache very securely, Zdziarski contended, so someone with know-how could recover months of typing in the order in which it was typed, even if the e-mail or text it was part of has long since been deleted.
