Apple has filed a patent title “Image-Based Authentication” that suggests it may be contemplating a move from authenticating with passcodes.

As reported by Wired UK, the patent depicts a new security system around object and people recognition in images. The system’s approach wouldn’t use the same image over and over again; rather, it would consider the images that have been recently used and displayed and vary the one used for security purposes.

The patent says that images could be tagged to have specific inputs required so that famous objects or people weren’t correct answers that would allow a stranger or another friend who knows the user’s friends have access to the device.

The patent also allows for increased security options by requiring multiple image identifications or in conjunction with another authentication factor.
