How is a biometric template generated?

A pattern is found by taking key characteristic measurements of the  shape of the lines that constitute the fingerprint. Some common key  characteristics that are used for this purpose are ridges and  bifurcations of the finger. These are now commonly referred to as Minutia points. The principle behind this is that two different images of the same  fingerprint will still present the same Minutia points if they are in  fact from the same fingerprint. The algorithms to generate these  templates are constantly improved and depurated; Ceelox’s architecture  was designed with these constant changes in mind allowing modular  capability to ensure the best algorithms are always available through  our products.
