Of course, there's absolutely no guarantee that Apple will implement this method in the future versions of iOS, but a patent application has recently surfaced describing how the technique could work in detail. Instead of having to enter a PIN code or a password, the user will be required to identify an object or objects in an image that's displayed on the screen. By the looks of it, in order to set this unlock method up, the device will have to scan its own storage space for images, and will then prompt you to add some key words describing these images. Each time you attempt to unlock your device, there may be a different image displayed. You'll be able to unlock device by either typing or saying the needed word.
Do you like this new unlocking method and would you use it should Apple decide to add it to iOS?
Here's the abstract from the patent application:
