Provided are a method and system for automatically tracking a face position and recognizing a face. In the present invention, after a face image of a user is captured, a capturing unit is moved such that the face image is moved to a face authentication region where optimum face recognition is performed, thereby having a changed capturing direction. This can allow face recognition of the user to be executed without movement of the user. Accordingly, convenience in face recognition can be maximized. Further, a plurality of registered face images are stored with matching frequencies indicating the number of times that the plurality of registered face images have been matched with an authentication image, and the authentication image is firstly compared with registered face images having large matching frequencies. This can enhance a face recognition speed.
