According to another exemplary embodiment, the wearable device 100 may determine through a proximity sensor whether a user is wearing the wearable device 100. The proximity sensor may be disposed on the contact portion when the user is wearing the wearable device 100. For example, in the case of a smart watch, the proximity sensor may be disposed below the display unit 120 to measure a distance between the smart watch and the user's wrist.
In operation 430, the wearable device 100 may identify the user by comparing the captured vein image with a registered vein image. The wearable device 100 may search for a vein image from among a plurality of vein images stored in the memory 130 that matches the captured vein image. When the wearable device 100 determines that the captured vein image and the registered vein image match each other by a predetermined ratio or more, in terms of a structure, or the like, the wearable device 100 may determine that the captured vein image and the registered vein image match each other. The wearable device 100 may then identify which user is wearing the wearable device 100 by determining which user corresponds to the matching registered vein image.
