A luggage lifting occurs frequently, but clearance rate is only 16.9 percent. For the prevention of this problem, there are some systems that use radio intensity. However, the accuracy of these systems is not high, and this system cannot identify the luggage lifting and the thing left behind. For the solution of the previously discussed problems, a new method to detect luggage lifting is proposed in this study. In the event of a luggage lifting, an owner is stopping and a lifting luggage is a walking state. In this method, a luggage lifting is recognized using the above properties. Thus, we define the two states (“Walking” and “Stopping”). By the use of acceleration sensors, the states of a luggage and the owner are able to be distinguished. In this proposed method, the luggage lifting is detected based on the states. This method can identify the luggage lifting and the thing left behind. In the event of a luggage lifting, the owner is notified with a sound, and the culprit is intimidated by warning sound. There is a strong likelihood that a criminal discard the luggage because the luggage warning sound is conspicuous. In addition, the accuracy to detect the luggage lifting is higher than that of conventional systems using radio intensity. By using this method, owners can be detected at an early stage luggage lifting. Therefore, the damage caused by the luggage lifting is reduced.
