1
Chapter 10 Handwriting Analysis, Forgery, and
Counterfeiting By the end of this chapter you
will be able to
  • Describe 12 types of handwriting characteristics
  • that can be analyzed in a document
  • Demonstrate an example of each of the 3 types of
    handwriting traits
  • Identify the major goal of a forensic handwriting
    analysis

2
Chapter 10 Handwriting Analysis, Forgery, and
Counterfeiting By the end of this chapter you
will be able to
  • Distinguish between the terms forgery and
    fraudulence
  • Identify several ways that businesses prevent
    check forgery
  • Describe 4 features of paper currency that are
    used to detect counterfeit bills

Introduction
  • Examine and compare questioned documents with
    known material
  • Questioned document source is in dispute or is
    uncertain (signature, handwriting, etc.)
  • Field investigations include
  • Handwriting
  • Computer printouts
  • Commercial printing
  • Paper and ink
  • Threatening, ransom, or suicide notes
  • Analysis helps identify a documents author

5
Introduction
  • Document Expert compares handwriting and other
    features using a scientific method.
  • vs.
  • Graphologist indicates the personality of the
    writer. Not accepted in the scientific community!

History of Forensic Handwriting Analysis
  • 1930shandwriting analysis played a role in the
    famous Lindbergh case.
  • 1999the US Court of Appeals determined that
    handwriting analysis qualifies as a form of
    expert testimony
  • To be admissible in court, scientifically
    accepted guidelines must be followed
  • Scotland Yard, the FBI, and the Secret Service
    use handwriting analysis

  • Letter Form
  • shape
  • curve
  • angle (slant)
  • size
  • connecting lines between letters,
  • correct letters (dotted is, crossed ts)
  • Line Form smoothness of letter and the darkness
    of the lines on upward and downward strokes
  • Formatting
  • Spacing between words and lines
  • Placement of words on a line
  • Margins a writer leaves empty on a page

10
Introduction to Handwriting
  • Everyones handwriting shows natural variations.
    Here are 6 of the 12 major, specific traits.

11
Introduction to Handwriting
  • The traits are functions of formatting or of
    letter or line form. Here are the other 6 of the
    12 major, specific traits.

Handwriting Examination
Each person has a unique handwriting style!!!
  • Two writings came from one person if
  • their similarities are unique and
  • no unexplainable difference(s) are found
  • Examine the questionable document for detectable
    traits and record them
  • Obtain a known sample of the suspects writing
    (an exemplar) used as a tool to include or
    exclude persons.
  • Compare and draw conclusions about the authorship
    of the questionable document

13
Handwriting Examination
  • Conscious writing effort to avoid this
  • Do Not show suspect the known document
  • Give no instructions on punctuation or grammar
  • Use similar pen or pencil

14
Technology Used in Handwriting Analysis
Initial comparisons are done with the naked eye,
lens or microscope!
  • Biometric Signature Pads
  • Learns to recognize how a person signs
  • Evaluates speed, pressure, and rhythm of the
    signature
  • Recognizes forgeries by the detection of even
    slight differences
  • Computerized Analysis
  • Compares handwriting samples objectively, and
    faster than by an individual
  • The Forensic Information System for Handwriting
    (FISH) is a database used and maintained by the
    Secret Service.

15
Handwriting
  • After handwriting samples are scientifically
    analyzed, the expert handwriting witness prepares
    a written report of the analysis to present to a
    jury.
  • Evidence in the Courtroom
  • Expert explains how comparisons were made
  • Cross-examination by defense attorney may follow
  • Shortcomings in Analysis
  • Are the base documents real or fake?
  • Did mood, age, fatigue impact the handwriting?
  • Did experts miss details any details?

16
Forgery
  • Forged documents include
  • checks
  • employment records
  • legal agreements
  • licenses
  • wills
  • Fraudulenceforgery for material gain
  • (to profit from the fake or
    alterations)

17
Forgery
  • Check forgery can include
  • ordering anothers checks from a deposit slip
  • altering a check
  • intercepting anothers check, altering, and
    cashing it
  • creating a check from scratch

18
Preventing Check Forgery
  • Chemically sensitive paper
  • Large font size requires more ink and makes
    alterations more difficult
  • High resolution borders that are difficult to
    copy
  • Multiple color patterns
  • Embed fibers that glow under different light
  • Use chemical wash detection systems that change
    color when a check is altered

19
Literary Forgery - forgery of a writing, such as
a historic letter or manuscript
  • Best forgeries aim to duplicate the materials
    found in the original
  • old paper
  • chemically treated materials to fake an older
    look
  • inks mixed from substances that would have been
    used at the time
  • watermarks that add the appearance of age
  • tools and styles that would have been popular at
    the time

Counterfeiting - when false documents or other
items are copied for the purpose of deception
  • A criminal activity existing since antiquity
  • Items commonly forged today include
  • Currency
  • Travelers checks
  • Food stamps
  • Certain bonds
  • Postage stamps
  • The number one way we suspect fakes is the feel
    of the texture

22
Counterfeit Currency
  • Security features are added to paper currency
    that scanning cannot reproduce
  • EX. Tiny intricate lines and details that
    cannot be scanned well
  • Regular printer paper contains starch.
  • Paper currency contains rag fiber instead of
    starch.
  • Government continues to change the design of
    paper money

23
Counterfeit vs. Authentic
24
Verifying Authentic Currency
  • New security features
  1. Portrait stands out and appears raised off the
    paper
  2. Contains clear red and blue fibers woven
    throughout the bill
  3. Has clear, distinct border edges
  4. Treasury seal is shown with clear, sharp
    saw-tooth points
  5. Watermark appears on the right side of the bill
    in the light

25
Verifying Authentic Currency
  • New security features
  • The security thread is evidenta thin embedded
    vertical strip with the denomination of the bill
    printed in it
  • There is minute printing on the security threads,
    as well as around the portrait
  • When the bill is tilted, the number in the lower
    right-hand corner makes a color shift from copper
    to green
  • Counterfeiting pens contain iodine which reacts
    with the starch in printing paper. Real currency
    does not contain starch. 98 effective.
  • Turns bluish-black when reaction occurs.
    Counterfeit !!!!
  • Turns pale yellow and fades away when exposed to
    real currency!

. . . . . . . . . . . . . . . . . Summary
  • Handwriting analysis compares questioned
    documents with exemplars to establish authorship.
  • Aspects of a persons handwriting style can be
    analyzed to ascertain authenticity.
  • Many new features of paper currency help prevent
    counterfeiting.
  • Technological advances have enhanced chances of
    detecting forged documents.
