Claim Text:
1. A system comprising: an imaging device with a line of sight to a curved object having a curved surface with a fingerprint thereon, which is to be captured in an image of the curved object; a light source configured to illuminate the curved surface of the curved object, the light source to produce light being reflected off of the curved surface, the reflected light including glare reflected along the line of sight; and a passive, non-transmissive optical barrier positioned in the line of sight from the imaging device to the curved object, said passive, non-transmissive optical barrier being spaced apart from the imaging device along the line of the sight and said passive, non-transmissive optical barrier being sized and positioned to reduce the reflected light off the curved surface of the curved object directed along the line of sight from being captured in the image by the imaging device, wherein the passive, non-transmissive optical harrier comprises a curved configuration.
