Abstract: Soleprint is an impression of the friction ridge of a part of the human plantar, a point on the sole of the foot adjacent to the big toe, at the flat space behind the toes, Lepers do have soleprint but mostly do not have fingerprint. The three (3) soleprint samples, a whorl, a loop and an arch were picked out of the 240 soleprint images collected from 120 lepers of 9 colonies in Nigeria, and compare withthree (3) fingerprint images, a loop, a whorl and an arch, drawn from a database created in 2010 during my PhD research. The fingerprint recognition algorithm was applied to the images for comparison, with interest in finding local ridges orientation, Gabor filtering and binarization. The orientation patterns revealed that fingerprint and soleprint images belonging to same class do have their line of orientation similar. The Binarized images were discovered to contain lots of false minutiae points because of dirt and little mutilation on the foot. The fact remains that 1/10 of a portion of the entire surface is sufficient enough to conduct a match. The image can also be enhancedusinga good technique for better results. The soleprint has identical features to that of the fingerprint that can produce minutiae points.
