Getting started
Thank you for choosing a Viro biometric product.
This item combines electronic combination opening with a sophisticated
fingerprint-based recognition system.
It is well known that digital fingerprints are a unique and irreproducible
characteristic for every single person, even in the event of close relatives like
twins.
Digital fingerprints also stay the same throughout a person’s life and are therefore
the best possible means of identification, universally recognised throughout the
world.
This recognition system of digital fingerprints is based on fingerprint particulars
(details) rather than on its overall image. This means that the system processes
the fingerprint and extracts its unique characteristics such as, for example, the
start, end and forks of the lines that make up the fingerprint, and calculates their
reciprocal position (Figure 1).
Figure 1:
The fingerprint is identified by the reciprocal
position of the points of its particulars
(details). This technique allows alterations to
be taken into consideration, such as small
cuts on the fingertip, and ensures maximum
privacy for the fingerprint image.
Using the details instead of the overall image not only reduces processing times
for recognition to a minimum, but also provides the following fundamental
advantages:
-
The system can tolerate physiological alterations of the fingerprint,
such as small cuts or scratches. It is in fact very unlikely that such alterations
can cover enough details to make the fingerprint unrecognisable. When the
cut or scratch heals, the fingerprint will in any case be exactly the same as it
was before.
-
The system can tolerate small movements of the fingerprint on the
reader with respect to the original position, since the reciprocal position of
the details does not change.
-
It is not possible to use the details to trace the complete image of the
fingerprint that generated the details, thus ensuring secrecy in compliance
with the legal regulations regarding privacy.
Thanks to this technology, you have chosen the best in security and practicality.
