Minutiae are unique characteristics of a fingerprint linked via algorithms. This linking forms a unique pattern called a minutiae template. Traditionally, minutiae points are ridge ending, bifurcating and core locations. Together they form a pattern, like a fingerprint, that is unique and detectable with great precision. Different applications favor the selection of one technique over another.
Performance varies based on the application and circumstances.
For example, fingerprint systems are unaffected by variation in ambient light conditions, while facial recognition is. We believe that fingerprint recognition has more versatility than all other systems. A very small group of people has damaged fingerprints that would not perform well in these systems and may generate a false rejection . Yes, the PFS-100 is an optical device that includes a prism and a CMOS sensor. Other devices are made from capacitors that measure galvanic response and thermal sensors that attempt to measure slight temperature differences between ridges and valleys in the fingerprint.
