These are ALMOST biometrics

Here are some biometrics that perform a weak identification, not an individual identification.

Voici quelques technologies biométriques qui sont une forme faible d'identification, mais pas une identication formelle d'un individu.


Proximal Phalanx / Age identification

It is interesting to know the age group of an individual, just to define its access rights (for instance to restrict access to mature content).

Il est intéressant de connaître l'age d'un individu, simplement pour définir ses droits d'accès (par exemple pour restreindre l'accès aux contenus adultes).

I-Mature proposes an age group recognition system.
Technical information : i-Mature performs a safe, non-invasive test with very low frequency of ultrasound waves, to determine the bone status of the user’s finger. The location of performed measurement is the Proximal Phalanx of the third finger.

Finger pressure

(2006 Sep) The Bio-Metric Scanner Room Guard announces nosy brothers or sisters trying to enter, while allowing silent entry only to the person whose hand matches the five-finger pressure-sensitive password. An alarm sounds if an “intruder” tries to enter! This electronic sentinel fits all doors and uses 3 AA batteries (sold separately). 3" x 5". Ages 9+.

These are NOT biometrics


Body Salinity
Salinité du corps

This is NOT a biometric trait, although some websites indicates as a possible future biometrics.
The confusion comes from a development conducted by IBM and the Massachusetts Institute of Technology (MIT). The Personal Area Network (PAN), works by exploiting the natural level of salinity, or salt, in the human body which is accomplished by an electric field which passes a tiny electrical current through the body (salt is an effective conductor of electricity), on which data can be carried. Speeds equivalent to a 2400-baud modem have been claimed, giving 400,000 bits per second data transfer (Computer Business Review, 1998).
The idea was to exchange (electronic) business cards when shaking hands... here is the identification part :-)

Ce n'est PAS une biométrie.
La confusion provient d'un développement mené par IBM et le MIT. Le "réseau personel" exploiterait la conductivité naturelle du corps humain grâce au sel, et servirait de conducteur pour échanger des données équivalentes à un modem 2400-baud.
L'idée était d'échanger sa carte de visite (électronique) au moment de se serrer la main... de là vient la confusion avec l'identité de la personne :-)
