In the feld of criminal justice, any testimony, no matter how minor or trivial, cannot be ignored, as supplementary evidence has always turned the case around. A common form of evidence is documentary proof. Document exhibits come in a number
of formats and can be handwritten, digital, or printed. Handwriting may be used as a
starting point for attempting to identify uniqueness. Different people have different
writing patterns, which is a natural act. Even if the person deliberately wants to alter,
certain characteristics are peculiar to a single person. On the basis of class and individual characters, an attempt was made to differentiate between male and female handwriting. In a case where the investigation involves handwriting, this can be a valuable
piece of supplementary evidence. It can also be used to exclude possible suspects. With
the writers using the same writing instrument and surface, over 200 samples were analyzed based on 6 parameters, and many of them yielded positive results in deciding
whether the writers were male or female. Te observation can be used as a frst step in
the feld of Graphology in terms of gender identity
