Abstract
Handwriting biomechanics may bear biometric value. Kinematic and kinetic handwriting characteristics of authentic and forged handwriting samples have been contrasted in previous research. However, past research has only considered pen-on-paper forces while grip kinetics, i.e., the forces applied by writers’ fingers on the pen barrel, have not been examined in this context. This study compares multiple grip kinetic features between repeated samples of authentic signatures and skilled forgeries in a sample of 20 functional adult writers. Grip kinetic features differed between authentic and well-practiced bogus signatures in less than half of the participants. In instances where forces differed between authentic and bogus, there was no clear trend in the difference. Forgeries are not necessarily associated with different or more variable grip kinetics. As long as the written text is well-practiced and written naturally, the handwriting kinetics tend to be similar to those of authentic signature writing.
