Abstract

Silicon fingerprint sensor cost is proportional to the area of silicon. Sweep sensors have been proposed to replace square sensors in order to reduce the cost, but are still quite large. This paper describes a simulation to determine what could be a reasonable minimum width of a sweep sensor. A database acquired with the FingerChip(r) is used as a reference, and FAR/FRR curves are computed using cropped images against full and reduced images.
