transmitting the third motion data to the portable electronic device in a fourth security state of the portable electronic device,

wherein the wearable device transmits the third motion data earlier than the first motion data to the portable electronic device.

3. The method of claim 1 , further comprising:

determining a wearing state of the wearable device;

determining a wearing plan state of the wearable device; and

providing a report that recommends left-wearing or right-wearing of the wearable device,

wherein the wearing plan state is a state in which the user motion over a pre-defined threshold is detected by the motion sensor in a non-wearing state.

4. The method of claim 3 , further comprising:

counting a collection period of the first motion data; and

providing a report that recommends the left-wearing or the right-wearing of the wearable device, depending on whether the collection period of the first motion data satisfies a pre-defined period.

5. The method of claim 3 , further comprising:

determining an amount of collection of the first motion data; and

providing a report that recommends the left-wearing or the right-wearing of the wearable device, depending on whether the amount of collection of the first motion data satisfies a pre-defined amount.

6. The method of claim 3 , wherein the report includes at least one of visual, audible and tactile reports, and in providing the report, an output direction of the report is determined using the motion sensor.

7. The method of claim 2 , further comprising:

determining a wearing direction whether a user wears the wearable device on a right side or a left side based on a part of the motion data collected in the motion sensor.

8. The method of claim 7 , further comprising:

adding the motion data collected through the motion sensor to the first motion data or the second motion data depending on the wearing direction.

9. The method of claim 1 , wherein the first motion data is registered and the second motion data is not registered.

10. The method of claim 1 , wherein the first motion data and the second motion data are registered.

11. The method of claim 1 , wherein the first motion data and the second motion data are registered.

12. The method of claim 2 , wherein the fourth security state is a state in which the portable electronic device is locked, and the first motion data and the second motion data are not registered.

13. The method of claim 1 , wherein the first motion data and the second motion data comprise a plurality of feature points extracted from information received from the motion sensor.

14. The method of claim 13 , wherein the plurality of feature points of the first motion data and the second motion data is extracted from the portable electronic device.

15. A method for measuring left and right balance of a wearable device, the method comprising:

wirelessly communicating with a portable electronic device;

receiving a first motion data generated by a user's motion through a motion sensor provided in a first wearable device during a certain period of time or during collection of a certain amount of data;

transmitting the first motion data to the portable electronic device, the portable electronic device being in a first security state;

collecting a second motion data generated by the user's motion through the motion sensor provided in a second wearable device during a certain period of time or during collection of a certain amount of data; and

transmitting the second motion data to the portable electronic device in a second security state of the portable electronic device,

wherein the portable electronic device outputs a comparison result of the transmitted first and second motion data in a third security state, and

wherein the first security state is a state in which the portable electronic device is locked, the second security state is a state in which the portable electronic device is locked, and the third security state is a state in which the portable electronic device is unlocked.

16. The method of claim 15 , further comprising

performing a wireless communication between the first wearable device and the second wearable device, and in transmitting the second motion data to the portable electronic device, the second wearable device transmits the second motion data to the first wearable device, and the first wearable device transmits the second motion data to the portable electronic device.

17. The method of claim 15 , wherein the first wearable device and the second wearable device are determined depending on whether the wearable device is worn on the user's right side or left side.

18. A wearable device comprising:

a wireless communication unit that wirelessly communicates with a portable electronic device;

a motion sensing unit that senses user's motion; and

a control unit,

wherein the control unit collects a first motion data, which collects the motion data generated by the user's motion through a motion sensor provided in the wearable device during a certain period of time or during collection of a certain amount of data, and transmits the first motion data to the portable electronic device in a first security state of the portable electronic device, and

wherein the control unit collects a second motion data, which collects the motion data generated by the user's motion through the motion sensor provided in the wearable device during a certain period of time or during collection of a certain amount of data, and transmits the second motion data to the portable electronic device in a second security state of the portable electronic device, and the portable electronic device outputs comparison result of the transmitted first and second motion data in a third security state, and

wherein the first security state is a state in which the portable electronic device is locked, the second security state is a state in which the portable electronic device is locked, and the third security state is a state in which the portable electronic device is unlocked.

19. The wearable device of claim 18 , wherein the control unit collects a third motion data, which collects the motion data generated by the user's motion through the motion sensor provided in the wearable device during a certain period of time or during collection of a certain amount of data, and transmits the third motion data to the portable electronic device in a fourth security state of the portable electronic device, the third motion data being transmitted to the portable electronic device earlier than the first motion data.

20. The wearable device of claim 18 , wherein the control unit determines a wearing state of the wearable device and determines a wearing plan state of the wearable device to provide a report that recommends left-wearing or right-wearing of the wearable device, and

the wearing plan state is a state in which the user motion over a pre-defined threshold is detected by the motion sensor in a non-wearing state.
