Handwriting, Document Analysis, and Electronic Media

ByHeidi H. Harralson, Larry S. Miller

Examinations of documents for purposes other than handwriting identification frequently require examination of original documents. Other requirements on the part of the examiner include: knowledge of products and product manufacture, experience with materials and their performance, understanding of appropriate technologies, and knowledge of scientific method and its application in testing. In order to analyze a signature digitally, and examine nonoriginal documents, there is a greater need to understand the technology behind digitization. The process of digitization involves the conversion of information into bits or bytes. An electronically-captured signature is one in which the signer employs conventional methods in physically signing a signature, except instead of using traditional ink and paper, the signer writes on a tablet or screen with a stylus or fingertip. It is sometimes important for document examiners to know how a digital signature may be a part of the digital signing process as digital signatures and electronic handwritten signatures are sometimes used together in signing a document.
