Description The study entitled “Determination of Common Characteristics in Handwriting of
Closed Genotypic Family Members” was carried out at the Department of Forensic Science,
SHUATS, Allahabad with the major objectives, To determine the similar and different
characteristics in handwriting of closely related genotypic family members, To study the
similarities in handwriting due to same copy book form, To establish a relationship between the
similarity and differences in handwriting due to hereditary and due to adaptability and To provide
a modified and enhanced examination method for questioned document examination.
Since there are several Legal Issues in Handwritten Document Examination which
includes Individuality Problem that is whether the handwriting of every Individual is distinct.
The Validation Problem that is whether the procedures used by examiners are repeatable and the
Uncertainty Problem that is whether the inevitable uncertainty in individualization /exclusion can
be quantified. To minimize this Statistical Tests can be used to address the individuality problem.
The method can be formalized to validate existing methods as being repeatable and the use of
computing the methods of analysis by which various probabilities of interest in quantifying
uncertainty in the opinion can be computed.
In the first phase of the work the chi square value for the observed frequency of writers of family
were observed and the results were computed as per Pearson chi square test with an alternate
hypothesis that different handwriting combinations of parent has a significant effect on child’s
handwriting,
The second phase of the thesis deals with the chi square value for the observed
frequency of writers among school students who have studied the same copy copybook form,
were collected from different English medium schools of Allahabad and the observations were
made after detailed examination of each set of writing. The results were computed as per Pearson
chi square test to test the Hypothesis considered.
The third phase of the work deals with the analysis to check the statistical significance
of the observations made during the study in order to establish a relationship between the
similarity and differences in handwriting due to hereditary and due to adaptability.
The last part the thesis deals with the computational analysis where 10 families
handwriting were computed in order to observe the similarities among parent and their offspring,
the handwriting were analyzed by a Graphical User Interface tool developed in MatLab, which
computes the values in pixel according to defined mathematical formula.
