Last March, Kaplin wondered if iPhones
live up to the hype they receive. Since then, Apple has released yet
another version of the iPhone and has sold millions of units despite mixed
reviews from both users and Consumer
Reports, a popular magazine that publishes reviews and comparisons of
consumer products.
Design and capability issues aside, there is another
argument against the iPhone – one that many users might not know about, or
think affects them. Not long ago I wrote about how increased connectivity has
allowed law
enforcement to develop new ways of catching criminals. If you're an iPhone
user, this may now pertain to you, too.
iPhone forensics is a new field of study for law enforcement
officials who are learning how to retrieve information from the phones in
criminal cases. This new discipline is made possible by the wealth of
information iPhones store unbeknownst to their users. Even when it appears that
users have deleted the information, it's still easily assessable by those who
know where to look.
People like Johnathan Zdziarski, a former hacker and now
author of the book iPhone Forensics,
know that the information saved in iPhones can be extremely telling. As he told
The Star Press, "These devices are people's companions today…They're not
mobile phones anymore. They organize people's lives. And if you're doing
something criminal, something about it is probably going to go through that
phone."
What Lies Beneath
Many users know that their cell phones can be tracked using cell
towers and if they've turned on the GPS locator. But the iPhone allows its users
to be tracked in other ways too.
- The
iPhone regularly stores information when users close applications. Need to use
a map? The iPhone can do that, but when closing out of the application, the
phone takes a screenshot and stores it. These images could be used to track
where a user was, which is useful in confirming a criminal suspect's alibi.
- Many
people rely on the camera-function of their phones for easy snapping and sharing.
What they may not know is that pictures taken with iPhones are embedded with
GEO tags and other identifying information, including the GPS location of where
the picture was taken along with the serial number of the phone it was taken
with.
- iPhone
apps store information about the user's location and history. This data is
intended to be used for targeted advertising, but it can also be useful for
police.
- The
keyboard cache logs everything that users type in order to learn autocorrect
for fixing typing mistakes. This cache is easily recovered by officials,
providing the order in which it was typed, if the content was an email or text,
and even if it had been deleted long ago.
Forensics experts say that even if this information is
deleted from an iPhone, it still lives in the database.
Thoughts
While iPhone forensics has a place for catching criminals,
there are millions of people who are iPhone users and do not commit crimes.
When Kaplin sent me the The Star Press article, he told me that his
iPhone-holding friends were indifferent when they learned about the stored
information.
I don't personally own an iPhone, but I am creeped out just
hearing about it. Just last night, I was reading a blogger's account of getting
a phone call from someone she didn't know while out to dinner. In that
instance, he used information from Foursquare to track her down. A savvy-enough
user could also track someone down based on the GPS information embedded in
iPhone photos.
As indicated in the comments from last
week's post on Internet security, privacy is often just an illusion. When
stories like this come to light, it's horrifying to see just how true that is.
If you own an iPhone, does this bother you? Should we even
be surprised by stories like this anymore?
What do you think?
