Signature identification and the questions of disguise, forgery, and genuineness account for a significant proportion of a document examiner's case load.
Abstract
It is also one of the most demanding fields of document examination. To gather and evaluate a body of controlled data on the likely methods of producing disguised and forged signatures, 144 subjects were surveyed. A first group of 72 subjects each completed one set of eight genuine signatures and one set of eight attempts at disguise of their signature. A second group of 72 subjects were each given one of the sets of genuine signatures produced by the first group. The second group was asked to produce two forgeries, using the set of genuine signatures as models. The data gathered enabled disguise habits and methods of forgery, and the most common failings in the quality of the forgery attempts, to be described and compared. (Publisher abstract)
