Abstract: An image password lock system by tracing the position information of the organism or article feature is provided. In this embodiment, a photographic device photographs a movable target object to read a dynamic image data. Moreover, the dynamic image data has a predetermined shooting range set to be a whole-region image, and the whole-region image has a central region and a plurality of specific password regions. A target object image is displayed by a display device, and then processed by an image processing device, thereby calculating a center coordinate point of the target object image in the dynamic image data, compiling a password constituted by a movement position of the target object image, displaying the password, and validating the password. Therefore, benefits of a novel password input mode without any contact, an efficient anti-theft function and the like are provided.
