Two mathematics from Arizona (USA) have developed a mathematical model to create fingerprints. This model allows to reproduce the image of fingerprints.

For modelling it has been taken into account that according to the geometry of the dactile buds appear three basic forms in the fingerprints: arches, curves and lines. For example, in the rounded buds of the fingers predominates the tendency to form lines and in the oppressed buds the arches. According to these mathematicians, these trends reproduce well the models they have developed.

But fingerprints can form complex figures. The model is not yet quite accurate, it has problems with ramifications and other particularities, but they have manifested their intention to gradually materialize.
