Apple has recently acquired a pair of new patent applications. The patent published by the USPTO is a gesture-based unlocking system for Apple’s devices iPhone and the iPad. The system involved in this is quite secure and somewhat similar to the Android based platform. But, the better part here is that the number of provisions are better than Android, making the encryption even harder.
The patent describes a gesture lock screen user interface elements which have a user changeable property. The user can change it in terms of both size and position. This would be quite effective as the changing size would make it easier or may be harder to hit and altering its position would prevent the potential hacking attempts on the device. There is also an option wherein the system can use invisible dots too.
Obviously Apple will introduce a lot more into it and completely differentiate it from Android and then will get it into its own devices.
