Apple is reportedly trying out a pattern-based unlocking system for its iOS devices such as the iPhone and iPad.

According to 9 to 5 Mac, Apple has already implemented the lock screen system internally to be used in the employee Apple Connect app for iDevices. However, it is not clear if the system will ever be released to the public.

Apple has been under constant pressure to deploy a more secure method of locking and unlocking its iOS-based devices.

However even after the roll out of the new pattern-based unlocking system, the iPhone users will have to face another security hole in the form of smudges. As per different researches, finger oil or smudges on the touchscreen of a device could allow someone decode a pattern lock code.

It may be noted here that Google has already deployed that kind of pattern lock system on Android OS-based devices.

At present, users of the iOS-based devices are capable of setting up a 4-digit unlock password or a longer character-based password to secure their devices.
