Abstract - Human identification is becoming one of
the major worldwide issues now days. Dental
biometrics is the leading biometric technique to identify
individuals on the basis of their dental characteristics.
Dental Features of persons are naturally unique, one of
feature include jaws of a person maxillary jaw (upper
jaw) and mandible (lower jaw). Here, most of the
similarities are matched so that human being can be
exactly identified by its unique feature i.e. maxillary
jaw. We will use efficient workable method to
authenticate humans correctly and identify them
properly, which is based on dental work information
extracted out from dental data. This paper is all about a
proposed method where it includes some major
processing stages that consist of preprocessing, feature
extraction, classification etc. This whole part will be
implemented in matlab software for easy identification.
Matlab software contains a powerful tool to employ all
processing stages.
Key Words: Dental biometric, maxillary jaw, mandible.
1.INTRODUCTION
The field of biometrics has got so much importance
from few years because it is an interesting and a
different way to identify humans than that of
traditional authentication systems previously
developed like passwords. Under various
circumstances e.g. disasters conventional biometric
characteristics like fingerprints etc, may not be able
to work because of their incompatibility in such
cases .In this case, dental features are considered a
useful tool for of human identification. In order to
achieve our desired mentioned goal, dental
biometrics automatically analyzes dental
radiographs, stored in a database through some
described processing. In addition to this, forensic
human identification is crucial and a big issue world-
wide. At present security conditions, biometric
identification is the most promising way to authentic
humans with highest accuracy rate. A lot of research
has been done in the field of different biometric
modalities like Finger-print, Iris, Hand-Veins etc to
identify humans. Within these various modalities,
Dental Biometric has leading edge over others.
Because of reason a lot of dental biometric
characteristics have been associated with maxillary
bone. Other modalities e.g. finger print, palm print;
they have more complex features in it. They might
leads sometimes towards high error rate. And also,
there analysis is more complex. Thus dental
biometrics gets priority over other in considering
features and analysis point of view. Approaching in a
different Way, the system of dental biometrics has
not as developed as some other modalities. In this
sense, it is being an intelligent approach to explore
the new fields of research. Human identification has
been done in various modalities like finger print, ear,
face, hand vein recognition. Various strategies have
been proposed and a lot of advancement is required
also.
The maxillary jaw is a name for the upper jaw, and it
includes several bones stuck (or fused) together, and
it is in front of and just below the cranium. Also
attached to the cranium and form the cheek, the
nose, and the roof of the mouth. The air filled space
known as maxillary antrum or sinus that sits just
under the cheekbone, and just above the roof of the
mouth.There is one on each side of the face, either
side of the nose. The anterior nasal spine is a bit of
bone which protrudes from the maxilla at the lower
end of the nose. The zygomatic process is a curved
