Hand Writing

At its base hand writing analysis for forensic purposes is simple: by comparing samples of the same hand writing it can be determined if it is authentic or a forgery. This possible because to a trained professional hand writing is like finger prints; unique to the individual.

Graphology can be considered the forerunner of forensic hand writing analysis. The two use similar components as a means of analysis. Although the two are similar hand writing analysis is based in science while graphology is based in psychology. Graphology started from the idea that hand writing originates in the brain and therefore can be used to create a psychological profile of the writer, while hand writing analysis is used for two main purposes. “One is to authenticate documents and other is used to link a suspect to a crime”1. Hand writing analysis seem basic but is actually very difficult because unlike finger prints writing can’t be broken down into eight specific classifications, it is built on comparative analysis on the premise of twelve characteristics. They are line quality, spacing of words, size of letters, lifts of the pen, connection of strokes, beginning and ending of strokes, unusual latter formation, pen pressure, slant, baseline habits, fancy writing habits, and placement of diacritics. By using these characteristics forensic hand writing analysts are able to notice subtle differences in hand writing which allows them to authentic documents and exclude or include suspects in a criminal criminal investigation.
