Analyzing handwriting or writing style
have been considered an art so far. But
with the advent of a calligraphy-deducing
application developed by Virginia-based
Gannon Technologies Group, the practice will
acquire a more scientifi c approach.
Gannon Technologies unveiled their
technology at the annual meeting of
American Association for the Advancement
of Science, where they were armed with a
dozen computers and a database of 500
handwriting samples, all of which were
reproductions of a single paragraph titled
“London Letter”. The company claims that
their application can differentiate varied
forms of handwriting while simultaneously
matching different samples of the
handwriting of the same person.

Here, the key functional area is statistical
analysis. From size to curvature gradation
of each and every character, the instrument
measures more than 200 different
parameters of a letter or a digit. Currently,
the group is also attributing a substantial
amount in research and development to
prove that the technology attains the same
accuracy level as that of DNA analysis.
It is felt that this technology of
evaluation will assign a scientifi c precision
to the forensic investigators’ or document
examiners’ efforts. Presently, this discerning
is solely dependent on manual skills to judge
and draw a conclusion on whether a writing
style presumed to be somebody’s is truly
his. But the prosecutors can challenge these
conclusions as they are aware about the fuzz
factor and the lack of proper technology to
substantiate such arguments. However,
with the new technology in hand, the
handwriting experts should calibrate
their scale of opinions ranging from
“certainty”, “highly probable”, “merely
probable” and “no conclusion” to
something more specifi c and fi gurative.
