wherein, the at least one processor is further configured to, when the information is received and the wearable device is authenticated by the wearable device, control the display to display the private screen.

3. The mobile device of claim 2 , wherein the at least one processor is further configured to, when the information is received and the wearable device is not authenticated, control the display to display the public screen comprising the notification that the information is received.

4. The mobile device of claim 2 , wherein the at least one processor is further configured to:

determine if the information is received while a user using the wearable device is absent, and

when the information is received and the wearable device is authenticated, include the information in the private screen.

5. The mobile device of claim 1 , wherein the at least one processor is further configured to, when second information is generated by the mobile device, include the second information in the private screen.

6. The mobile device of claim 1 ,

wherein the at least one processor is further configured to, when the information is not received, determine an application to include in the private screen.

7. The mobile device of claim 1 , further comprising:

a communication device configured to connect the mobile device to the wearable device; and

an auxiliary signal detector configured to detect an auxiliary signal generated by the wearable device,

wherein, when the auxiliary signal is detected, the at least one processor is further configured to determine if the wearable device is authenticated based on the auxiliary signal.

8. The mobile device of claim 7 ,

wherein a communication signal of the communication device has a transmission distance shorter than a transmission distance of the auxiliary signal, and

wherein the auxiliary signal includes a magnetic field.

9. The mobile device of claim 1 , further comprising:

a GUI generating unit configured to generate the public screen and generate the private screen.

10. A method for displaying a screen of a mobile device comprising:

receiving information;

determining whether a wearable device is proximate to the mobile device; and

in response to determining that the wearable device is proximate to the mobile device, displaying one of a private screen comprising the information and a public screen comprising a notification that the information is received based on whether the wearable device is authenticated by the wearable device.

11. The method of claim 10 , further comprising:

when the information is received and the wearable device is authenticated by the wearable device, displaying the information in the private screen,

wherein the wearable device is authenticated based on authentication information input into the wearable device.

12. The method of claim 11 , when the information is received and the wearable device is not authenticated, displaying the public screen comprising the notification that the information is received.

13. The method of claim 11 , further comprising:

determining if the information is received while a user using the wearable device is absent, and

when the information is received and the wearable device is authenticated, including the information in the private screen.

14. The method of claim 10 , further comprising, when second information is generated by the mobile device, including the second information in the private screen.

15. The method of claim 10 , further comprising, when the information is not received by the mobile device, determining an application to include in the private screen.

16. A non-transitory computer-readable recording medium comprising a program for executing a method for displaying a screen of a mobile device, the method comprising:

receiving information;

determining whether a wearable device is proximate to the mobile device; and

in response to determining that the wearable device is proximate to the mobile device, displaying one of a private screen comprising the information and a public screen comprising a notification that the information is received based on whether the wearable device is authenticated by the wearable device.

17. A wearable device comprising:

an input device configured to receive authentication information from a user;

a communication device configured to connect the wearable device to a mobile device;

an auxiliary signal generating unit configured to generate an auxiliary signal; and

at least one processor configured to, in response to the wearable device being connected to the mobile device and the wearable device being authenticated based on the authentication information, control the auxiliary signal generating unit to generate the auxiliary signal comprising a magnetic field.

18. The wearable device of claim 17 , wherein the auxiliary signal has a transmission distance shorter than a transmission distance of a communication signal of the communication device.

19. The wearable device of claim 17 , further comprising:

a storage configured to store authentication information,

wherein the at least one processor is further configured to determine if the wearable device is authenticated by comparing the stored authentication information with second authentication information received though a user interface.

20. The wearable device of claim 17 , further comprising:

a release detector configured to detect detachment of the wearable device,

wherein the communication device transmits release information to the mobile device to stop displaying a private screen.

21. The wearable device of claim 17 , wherein the at least one processor is further configured to generate a user interface to perform authentication with respect to the user who uses the wearable device,

wherein a communication signal and the auxiliary signal are used for a second authentication.

22. A method for controlling a wearable device, the method comprising:

receiving authentication information from a user;

determining whether the wearable device is authenticated based on the authentication information;

when the wearable device is authenticated and the wearable device is proximate to a mobile device, performing local area communication to connect the wearable device to the mobile device; and

in response to connecting to the mobile device, generating an auxiliary signal comprising a magnetic field to control the mobile device.
