NIST (National Institute of Standards and Technology - USA), to gain more knowledge on the
issue of biometric standards and to be able to express our position on this respect.
We have to bear in mind how much quicker it would have been the work of “Mothers and
Grandmothers of the Plaza de Mayo” to find the children and grandchildren of their disappeared
relatives during the military regime in our country, if they had had more biometric records and
methods in the database with automated identification verification systems that collect this
information in an inviolable manner.
The point is that now to ensure a biometric identity one method is not enough (for
example only fingerprints) but what has been called “the biometric pyramid” has to be
considered.
The Biometric Pyramid
Human beings since their origin, that some researches date back to the old Chinese dynasties
or at least “before Christ”, have been using fingerprints as an additional element to “sign” their
work of art or possessions, allowing the verification of this fingerprint against the ones of the
individual who was claiming authorship or property. 6
A fingerprint is undoubtedly the most effective biometric method in the history of humanity,
as up to now, and considering the hundred million automated fingerprint records in the world,
there has not been found one single fingerprint identical to another individual’s fingerprint, not
even in the same individual. 7
If static biometric methods (because there are also dynamic ones or also called behavioural)
are represented by chess pieces we could say that the “Queen” would be the fingerprint. As
in other methods, its qualities of being perennial (since the moment they are formed they are
kept invariable in number, position, shape and direction), immutable (they do not mutate, since
they are formed at the sixth week of intrauterine life they do not change and they regenerate
to their original design) invariable (they cannot vary and also, depending on the cut produced
by an injure, they either regenerate or the design is invalidated by the scar, but their shape
does not change) and diversiform (they are all different), they are given supremacy over other
identification methods, moreover on the base that in crimes the biometric elements (traces) are
the most found. Nevertheless, it has to be taken into account that there is no religion or “uses
and customs” that oblige an individual to wear gloves or to cover them, for which a fingerprint
is the most exposed identification elements in everyday life.
Being able to approach the highest accuracy degree is a matter of usability, practicality and
statistics. For this reason it is not necessary to add any other biometric methods for not being
essential nowadays.
Following with the chessboard, although the “King” could be the DNA (Deoxyribonucleic Acid)
for its accuracy, and in security issues by the elements found as “traces”, it also has some
resistance in privacy aspects and sample handling as well as its use that, in some countries, is
