     "Face Recognition Technology"
     Law and Order Magazine
     nov 2001 issue

face recognition technology analyzes contours and
bone structures of the face and converts it into
a code or number. A data base is then searched
to see if the code matches a know criminal or
person.

The key to the FACETRACE technology is a
"good frontal shot of the face with both
eyes shown"

Another issue concerning face recognition
is the ability of individuals to deceive
the camera by using sunglasses, wearing hats,
growing facial hair, etc.

According to Dan Blackburn, "if sunglasses
actually hide the eyes, identification is
made more difficult." he did indicate that
as long as the sunglasses do not
totally conceal the eyes, identification is
possible. the same is true for hats and
facial hair. (so criminals and fugitives
hide your eyes with the biggest and blackest
sunglasses you can find! even at night time)

Research revealed that the likelihood of
finding the correct person is about 99% with
a camera angle of 15-25 degrees. the probability
drops to 88% for a 40 degree  camera angle, and
58% for a 60 degree camera angle. (privacy seekers
keep as far away from the camera as you can)

As expected the shorter the distance between
the subject and the camera the greater the
accuracy.

The lighting must be good enough to see the
face clearly, without significant shadowing.

One use of face recognition technology is
using it to decide who to question.

At a border crossing the government
has a data base of know drug traffickers
and pictures of people crossing the
border are compared for matches. those
that match are questioned.  or it could
be a government roadblock or checkpoint.
(so if the government has your photo and
wants to talk to you keep away from the
cameras)

For freedom lovers and civil right activists
I recommend reading law and order magazine.
its written by cops for cops. if you have
not already figured it out you will see
that cops are more interested in protecting
the government and the police, not the citizens.

You will find articles routinely written with
the attitude of getting a conviction is more
important then obeying in the bill of rights.
and that officer safety is more important the
citizen safety and civil rights.
