iPhone lock-screen password app pulled

Apple has removed a third-party application that was gathering user-submitted lock-screen passwords for what its creator claims were research purposes.

The software, dubbed "Big Brother Camera Security," was created by developer Daniel Amitay to serve as an alternative to Apple's lock-screen security.

Users could run it when leaving their iPhone or iPod Touch unattended, and the application would require an iOS-style passcode to resume. If a user entered the incorrect password, the software would take a photo of that person, and if the app was exited, an alarm would sound.

A side feature, added by Amitay in the most recent software update, began sending him user-entered passcodes, which were anonymized. Amitay on Monday posted the results of that data, which was made up of 204,508 recorded passcodes, to show what some of the most common passwords were. The move did not go over well in Cupertino. "Got a call from Apple last night regarding the removal of Big Brother from the App Store," Amitay wrote in a blog post today. "Apparently, Apple believed that I was 'surreptitiously harvesting user passwords,'" Amitay wrote.
