The method includes: obtaining identification information used to identify a user based on bio information of the user that is obtained by a device; determining whether control over an external device is approved based on the identification information; obtaining control information used to control an operation of the external device based on the determination; and transmitting a message including the control information to the external device. ## Claims ### Claim 1 A method, performed by a device, of transmitting a message, the method comprising: obtaining identification information used to identify a user based on bio information of the user, wherein the bio information is obtained by the device; determining whether control over an external device is approved based on the identification information; obtaining control information used to control an operation of the external device based on the determining; and transmitting a message comprising the control information to the external device. ### Claim 2 (depends on 1) The method of claim 1, wherein the obtaining of the control information comprises: obtaining state information indicating a current state of the user based on the bio information; and obtaining the control information that is determined corresponding to the state information. ### Claim 3 (depends on 1) The method of claim 1, wherein the obtaining of the control information comprises obtaining the control information when it is determined that the control over the external device by the user is approved. ### Claim 4 (depends on 2) The method of claim 2, wherein the message further comprises the identification information and the state information. ### Claim 5 (depends on 4) The method of claim 4, wherein the identification information is stored in a predetermined first field of the message, the state information is stored in a predetermined second field of the message, and the control information is stored in a predetermined third field of the message. ### Claim 6 (depends on 1) The method of claim 1, wherein the obtaining of the identification information comprises obtaining the bio information by using a sensor included in the device. ### Claim 7 (depends on 1) The method of claim 1, wherein the bio information comprises at least one of fingerprint information, heartbeat information, iris information, vein information, palm pattern information, gait information, blood vessel information, body temperature information, electrocardiogram (ECG) information, blood pressure information, and location information. ### Claim 8 (depends on 1) The method of claim 1, wherein the determining of whether the control over the external device is approved comprises: determining an identification (ID) corresponding to the user based on the identification information; and determining whether the determined ID is included among one of more IDs that are allowed to control the external device. ### Claim 9 (depends on 1) The method of claim 1, wherein the control information comprises priority order information indicating an order of the control over the external device by a plurality of devices among which is included the device. ### Claim 10 A device comprising: a bio information obtaining unit configured to obtain bio information from a user; a controller configured to: obtain identification information used to identify the user based on the obtained bio information, determine whether control over an external device is approved based on the identification information, and obtain control information used to control an operation of the external device based on the determination; and a transmission unit configured to transmit a message comprising the control information to the external device. ### Claim 11 (depends on 10) The device of claim 10, wherein the controller is further configured to: obtain state information indicating a current state of the user based on the bio information, and obtain the control information determined corresponding to the state information. ### Claim 12 (depends on 10) The device of claim 10, wherein the controller is further configured to obtain the control information when it is determined that the control over the external device by the user is approved. ### Claim 13 (depends on 11) The device of claim 11, wherein the message further comprises the identification information and the state information. ### Claim 14 (depends on 13) The device of claim 13, wherein the identification information is stored in a predetermined first field of the message, the state information is stored in a predetermined second field of the message, and the control information is stored in a predetermined third field of the message. ### Claim 15 (depends on 10) The device of claim 10, further comprising a sensor configured to obtain the bio information. ### Claim 16 (depends on 10) The device of claim 10, wherein the bio information comprises at least one of fingerprint information, heartbeat information, iris information, vein information, palm pattern information, gait information, blood vessel information, body temperature information, electrocardiogram (ECG) information, blood pressure information, and location information. ### Claim 17 (depends on 10) The device of claim 10, wherein the controller is further configured to: determine an ID corresponding to the user based on the identification information, and determine whether the determined ID is included among one or more IDs that are allowed to control the external device. ### Claim 18 (depends on 10) The device of claim 10, wherein the control information comprises priority order information indicating an order of the control over the external device by a plurality of devices among which is included the device. ### Claim 19 (depends on 1) A non-transitory computer-readable recording medium having embodied thereon a computer program for performing the method of claim 1. ### Claim 20 A computer-program product comprising a non-transitory computer-readable storage medium having instructions for: obtaining identification information used to identify a user based on bio information of the user, wherein the bio information is obtained by the device; determining whether control over an external device is approved based on the identification information; obtaining control information used to control an operation of the external device based on the determining; and transmitting a message comprising the control information to the external device.
