摘要： An authentication apparatus is provided. A forgery determination threshold is determined on the basis of two types of parameters, a forgery similarity and a forgery difficulty. If a calculated value for an object under test is lower than or equal to the forgery determination threshold, then, it is determined that the object is a biologic object. Thus, easiness in impersonation with a fake of a biologic object that is easy to forge may be reduced, and a false rejection due to a determination in which a biologic object is erroneously determined as a fake may be reduced.

摘要： The present invention intends to provide a method for liveliness detection and fitness measurement using information optically extracted from a fingertip. For liveliness detection, the present method examines the change in a color index of a finger at its touching portion measured while the finger is being pressed onto an inspection surface and while the finger is released from the same surface. If the change is equal to or larger than a predetermined value, the finger is regarded as a live finger. For fitness measurement, an index indicative of the stiffness of the blood vessel of the finger is obtained from the change in the color index of the finger at its touching portion against the change in the contact area of the finger while the finger is being pressed onto the inspection surface.

摘要： A finger sensing device may include a finger sensing area, at least one processing stage coupled to the finger sensing area and having at least one adaptively determined processing parameter, and a controller for spoof reduction. More particularly, the controller may determine a spoof attempt based upon a change in the at least one adaptively determined processing parameter. For example, the at least one adaptively determined processing parameter may include a feedback determined processing parameter. Accordingly, the finger sensing device has enhanced spoof reduction, since different materials, for example, will cause a change in an adaptive processing parameter and thereby indicate the attempted spoof.

摘要： Disclosed is a method for detecting a latent fingerprint image provided to a biometric input device of a fingerprint based security system. First and second images of the fingerprint are captured during a time period interval Δt. At least one of the first and second images are analyzed to identify an extractable feature within a global reference frame, the extractable feature useable for authenticating an individual. The first and second images are compared one with the other to determine differences indicative of motion about the identified extractable feature within a local reference frame during the time period interval Δt. Absent motion about the identified extractable feature being detected, the fingerprint is registered as a latent fingerprint and cannot be used to authenticate the individual who is seeking authorization.
