Twister Ninja Software is developing a new program for the iPhone called “Lockbox”. With it, you can secure photos and notes. To unlock them you must make a gesture on the screen that has been pre-programmed. The author claims it has no weaknesses and, so far, is completely secure. Apple’s 4 digit PIN only takes about 10,000 inputs to break, this software takes significantly more. The gesture ranges from 12 to 20 cells so almost any pattern can be imagined. Here’s a link to the Lockbox site and here’s one to his Blog.
