Scrutiny and Comparison of Handwriting Characteristics in Questioned Guided Signatures with Standard Signature Samples

Abstract

Signatures are the identity of individuals. Eventually, signatures can be used to prove authenticity of a person. Guided signatures are hereby the signatures that are executed by the individual, by the help of a guided or assisted hand. Guided or assisted signatures are more often confused with the forgery. Though, it is incorrect to say that the guided or assisted signatures are always guided or assisted by the permission of the individual whose signatures are to be executed. So, guided or assisted signatures to require strenuous efforts by the examiner to determine the genuineness of the signatures. In the presented study aim was to determine the characteristics in case of guided signatures and to find the impact of the handwriting of guider handwriting over the handwriting of the genuine signature holder. In this study, 135 signature samples were collected from 90 individuals. The age group ranges from 25 to 60 years. The guided signature samples were collected in a pair, in which one was the individual whose signatures have to be executed and the other individual will be the guider. The features observed were alignment, hesitation, initial and terminal strokes, I dot and t crossbar, pen pause, pen pressure, size of letters, slant, spacing, style of writing, retouching, embellishment, and underscore. This study will assist in determining the peculiar class characteristics of handwriting to be found in guided signatures, also the difference between forgery and guided signatures can be made.
