create variable of the reference pattern corresponding to the multi-touch input, based on at least one of the touch area or the touch shape, which correspond to the touch regions of the multi-touch input.

4. The electronic device of claim 1, wherein the processor is further configured to:

detect a touch movement corresponding to a first touch input among the at least one touch input, and

create variables of the reference pattern corresponding to the first touch input by additionally using the detected touch movement, based on at least one of the touch area, the touch shape, or the number of touches, which correspond to the first touch input.

5. The electronic device of claim 1, wherein the processor is further configured to create at least one of a haptic effect or a graphic effect to correspond to at least one of the touch area, the touch shape, or the number of touches.

6. The electronic device of claim 1, wherein the processor is further configured to:

create a user input pattern, based on at least one of the touch area, the touch shape, or the number of touches, which correspond to each of the at least one touch input detected through the touch screen, and

unlock the electronic device, based on the comparison result of the user input pattern and the reference pattern.

7. The electronic device of claim 6, wherein the processor is further configured to:

unlock, if the user input pattern matches the reference pattern, the electronic device, and

maintain, if the user input pattern does not match the reference pattern, the electronic device in the locked state.

8. An electronic device comprising:

a touch screen; and

a processor configured to;

detect a touch area corresponding to each of a plurality of touch inputs detected through the touch screen,

detect an average of the touch areas corresponding to the plurality of touch inputs, and

create a reference area for separating the touch area to create an input pattern corresponding to the unlocking of the electronic device, based on the average of the touch areas.

9. The electronic device of claim 8, wherein the processor is further configured to:

separate the type of touch area corresponding to each touch input of the plurality of touch inputs, based on the comparison result of the touch area corresponding to each touch input of the plurality of touch inputs detected through the touch screen and the reference area, and

create a reference pattern for the unlocking, based on the type of touch area corresponding to each touch input of the plurality of touch inputs.

10. The electronic device of claim 9, wherein the processor is further configured to:

separate the type of touch area corresponding to each touch input of the plurality of touch inputs, based on the comparison result of the touch area corresponding to each touch input of the plurality of touch inputs detected through the touch screen and the reference area,

create a user input pattern, based on the type of touch area corresponding to each touch input of the plurality of touch inputs, and

unlock the electronic device, based on the comparison result of the user input pattern and the reference pattern.
