A method for identification of past document falsification

The gradual decline in the motor system and in general body functions, such as cognitive, kinematic, working memory, motor performance, and neuromuscular functions, as age increases will change a signature’s features gradually, and after a relatively long period of time, such changes can be differentiated. We introduce an approach for identifying the changes in a signature’s features with the age of the same person within a certain time period. The method is potential for countering the crime associated with falsification of documents created in the past by the same person, as a complement to the already standard methods with an error of less than three years. This work has been published in Australian Journal of Forensic Science with the title “How human age affects the signature’s curvature, density, and amplitude to wavelength ratio and its potential application for countering document falsification
