Claim:
An image password lock system by tracing the position information of the organism or article features, comprising: a photographic device, for photographing a movable target object to read a dynamic image data having a predetermined shooting range set to be a whole-region image; the target object corresponds to a target object image; and the whole-region image has a central region and a plurality of specific password regions, wherein a number of the specific password regions is eight, respectively located above, top right of, right of, bottom right of, below, bottom left of, left of, top left of the central region, and represented by 1, 2, 3, 4, 5, 6, 7, and 8, respectively; a display device; and an image processing device, including: a calculation module of a center point of the target object, for calculating a center coordinate point of the target object image in the dynamic image data; a validation module of the target object movement, for outputting a password corresponding to one of the specific password regions, when the center point of the target object image moves toward one of the specific password regions from the central region and then back to the central region, wherein the validation module of the target object movement outputs a warning action to indicate that the specific password region has not been reached when the center point of the target object image moves toward but still away from the specific password region; a password display module, for displaying the password output on the display device; and a password validation device, for comparing whether the password is the same as a predetermined correct password, where when the password is the same as the predetermined correct password, outputs a password-correct action.
