detect the face of the target person based on the additional indication.

15. The electronic device of claim 11 , wherein the connection controller is further configured to:

transmit a connection request including the at least one facial feature;

receive, from the target device, a response message for connecting to the electronic device; and

establish the connection with the target device based on the response message.

16. The electronic device of claim 15 , wherein the response message includes security information for verifying the target device, and

wherein the connection controller is further configured to verify the response message based on the security information.

17. The electronic device of claim 16 , wherein the security information includes at least one of environmental sound data captured by the target device and facial feature data of a user of the electronic device.

18. The electronic device of claim 11 , wherein the connection controller is further configured to:

transmit a connection request including the at least one facial feature; and

establish the connection with the target device based on whether a plurality of response messages is received for connecting to the electronic device.

19. A non-transitory computer-readable storage medium comprising instructions for connecting to a target device, the instructions causing a processor of an electronic device to perform the operations of:

capturing an image including a pointing object and a face of a target person associated with the target device;

recognizing an indication of the target person, wherein the indication corresponds to at least the pointing object in the captured image;

detecting the face of the target person in the image based on the indication;

extracting at least one facial feature of the face in the image; and

connecting to the target device based on the at least one facial feature.

20. The non-transitory computer-readable storage medium of claim 19 , wherein recognizing the indication comprises detecting the pointing object in the image as the indication of the target person.

21. The non-transitory computer-readable storage medium of claim 19 , wherein recognizing the indication further comprises:

receiving an input sound; and

recognizing a speech command from the input sound as an additional indication of the target person.

22. The non-transitory computer-readable storage medium of claim 19 , wherein connecting to the target device comprises:

transmitting a connection request including the at least one facial feature;

receiving, from the target device, a response message for connecting to the electronic device; and

establishing the connection with the target device based on the response message.

23. The non-transitory computer-readable storage medium of claim 22 , wherein the response message includes security information for verifying the target device, and

wherein establishing the connection with the target device comprises verifying the response message based on the security information.

24. An electronic device for connecting to a target device, comprising:

means for capturing an image including a pointing object and a face of a target person associated with the target device;
