Questioned Document Examination System

Background

Writing by hand has been a major method of communication for centuries. Between the twelfth and thirteenth centuries writing was used by the educated classes, and has evolved today to the point that the written signature is universally recognized as legal identification. Each of us learns to write according to a prescribed school copy, but as soon as we reach writing fluency we alter the form and size ratios in a manner peculiarly characteristic to our writing style. This writing style differentiates our writing from others.

Document Examination is an established field of scientific study that came into being early in this century as a means of identifying forgery and establishing the authenticity of documents in dispute. It grew out of the need to correctly evaluate document evidence in court. Forgery has been practiced from the earliest times wherever writing was the medium of communication. Because an examiner's work involves some form of handwriting the field is sometimes referred to as "Handwriting Identification" or "Handwriting Analysis" and the practitioner as a "Handwriting Expert". See Wikipedia's description of Questioned document examination (QDE).
