Abstract: A method and an apparatus for authenticating a user using height of the user are provided to enhance convenience of the user by accurately authenticating users without using complicate user authentication information. A face recognition unit(122) detects a face region from an image obtained by a camera, and calculates a first height from an intersection between an elongated line from an FOV(Field of View) and a user face to a head tip of the user. A distance sensor(124) calculates a first distance from the camera to the intersection between the elongated line and the face of the user. A memory(130) stores a third height between a ground and the camera. A key calculator(125) calculates a second height from the camera to the intersection between the elongated line from the FOV and the user. The key calculator uses a moving angle of the camera and the first distance. A controller(100) controls the face recognition unit according to a user request, calculates the first height and the first distance, and calculates a height of the user.
