According to a recent eWeek.com article, Daniel Amitay, the developer of the iPhone app Big Brother Camera Security, discovered that a fascinating 14.4 percent of its users have one of ten common four-digit PIN codes.
Built for the iPhone 4, Big Brother Camera Security uses the front-facing camera to automatically take a picture of anyone using the phone at a given time. The rationale behind this application is to keep track of any unauthorized users of the device. In the latest update for the app, code was added to collect information regarding the PIN used to secure the application.
Out of 204,508 codes that were anonymously sent, ‘1234’ was the most commonly used with 4.3 percent users.
“With a 15 percent success rate, about 1 in 7 iPhones would easily unlock,” Amitay said.
Since a PIN only contains 4 characters, the max possible combinations of numbers that could be formed is only 10,000 different combinations, which is not very secure and can be brute forced almost instantly. Passwords in the form of gestures and alphanumeric characters not limited by size are by-far more secure than simple 4-digit passwords.
Big Brother Camera Security was pulled from the App Store yesterday. More details via Macstories
