Abstract:
A human body-recognizing combination lock comprising:a body part imaging device operable to obtain a plurality of images of one or more human body parts, said images having a spatial or temporal relationship with respect to one another; an image comparing computational element, responsive to said images from said imaging device, and operable to compare said images against a set of reference images of said one or more human body parts of an authorized user according to a first pre-determined criterion to ascertain whether said images meet said first pre-determined criterion and to compare said relationship of said images against a reference relationship selected by said authorized user to determine whether there is a match according to a second pre-determined criterion, wherein said computational element is adapted to produce an output recognition signal only if both said both first and second pre-determined criteria are met wherein said computational element detects said images that are obtained at different times, said recognition signal being output only when all of said images meet said first pre-determined criterion in a proper sequential order according to said second pre-determined criterion.
