ABSTRACT:
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.
