Electronics giant Samsung is seeking a patent for a new way to unlock smartphones using a drawing or doodle. The said patent was filed in September 2012, according to Global Post.

A portion of the patent filing read: "The feature allows users to unlock (smartphones) in a more convenient way. As patterns are not restricted to an area, spot or shape, users can unlock screens more freely than before."

According to VentureBeat, the new technology also allows users to set "hot keys" for certain apps and commands by dragging the finger or stylus across the screen. Functions such as call answering, call rejecting, or camera activation could be brought up with pre-set doodles and without the use of the lock screen. The number of intersections in the drawing will determine the app or command to be used, the report explained.

The Korean Intellectual Property Office revealed the patent filing on Thursday, Global Post reported.
