This document discusses different types of forgery including:
1. Free hand forgery which involves copying a model signature without direct tracing.
2. Transplantation forgery which is transferring a signature or image from one document to another, often using computers or photocopying to commit fraud.
3. Forgery over a genuine signature which alters an original document signed legitimately to deceive the signer, such as changing amounts on a check.
Detection methods include examining paper fibers, ink, handwriting style, and instrument marks to determine if a signature or document has been tampered with or forged. Forensic analysis plays an important role in uncovering forgery attempts.
1) Manual typewriters produce identifiable characteristics over time such as misaligned or damaged letters that can be used to match documents to a specific machine.
2) Electric typewriters use either a daisy wheel or golf ball to print letters, which deteriorate with use and produce flaws that appear across documents from the same machine.
3) Printers are more difficult to trace to a specific device than typewriters, but laser printers may transfer tiny scratches that offer identifying evidence.
Class characteristics are common features of handwriting within a group, such as size, spacing, speed, slant, and skill. Size refers to the largeness of writing. Spacing is the amount of space between letters, words, and lines. Speed is the time it takes to write. Slant is the angle of letters relative to the baseline. Skill improves with practice. Other characteristics include pen pressure, movement, alignment, and line quality.

The examination of questioned documents involves both criminalistic examination to detect forgeries and alterations, as well as handwriting identification to determine authorship, which requires extensive study and experience. The scientific process involves analyzing, comparing, and evaluating characteristics and properties between questioned and known documents.
Handwriting refers to writing created with a pen or pencil and can include both printing and cursive styles. Each person's handwriting is unique, making it possible to verify the writer of a document and identify health issues based on deterioration of handwriting over time. There are two main types of handwriting analysis: graphology which studies how handwriting reveals personality and character traits, and forensic document examination which determines if unknown writing samples match known writing samples, such as in ransom notes, forged documents, death threats, or suicide notes. Forensic document examiners analyze and compare known and unknown writing samples based on various characteristics to determine if they were written by the same person.
This document discusses handwriting analysis and the analysis of signatures and documents. It provides information on how to analyze writing characteristics like style, skill, alignment, individual letters, size, slant, speed. It describes different types of forgeries like freehand, simulated, traced, and techniques to alter documents. The document then discusses a specific Singapore Supreme Court case where handwriting analysis was used to determine if a signature on a letter was forged. A fourth expert was brought in and used human behavior science in addition to handwriting science to make a determination in the case.
Document analysis examines questioned documents to determine authenticity by comparing them to known samples. Questioned documents include signatures, writing, or marks whose source is uncertain. Experts analyze characteristics like handwriting style, paper type, and added security features to detect alterations. Handwriting is unique to each individual and difficult to forge. Forensic document examiners follow scientific guidelines to compare questioned samples to known exemplars and determine authorship in court.
This document discusses the nature and scope of questioned document examination. It defines questioned documents as any document whose authenticity or authorship is in doubt. Common questioned documents include checks, wills, contracts, and letters. The analysis of questioned documents involves examining the document and comparing similarities and differences to known samples to determine if they were produced by the same source. Handwriting analysis is an important part of document examination, as handwriting is unique to each individual. Experts analyze handwriting traits and compare questioned documents to handwriting exemplars. Forgery and counterfeiting are also discussed, as are security features used to prevent fraudulent reproduction of documents like checks and currency.
Document examiners analyze questioned documents through years of training to recognize individual handwriting characteristics. No two individuals write exactly alike due to unique factors like letter style, spacing, and writing skill. Examiners compare a sufficient number of these characteristics between known and questioned samples to determine authorship, though no single factor is definitive on its own. Proper collection of known writing exemplars is critical for the examination outcome.
This document discusses various types of disputed documents that may be examined by forensic document examiners. It describes questioned documents as any material containing marks intended to communicate a message that is potentially disputed in court. Forensic document examiners use scientific methods to examine questioned documents to determine their authenticity, identify alterations, and attribute handwriting or machine printing to help resolve legal disputes.

Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

2. WHAT IS A QUESTIONED DOCUMENT ?
Any object that contains handwritten, typewritten markings, alphabets,
letters, words, markings or combination of all whose source or authenticity
is in doubt.
Questioned Document Examination is a branch of forensic science that
deals with documents having a suspicious authenticity. Also called as
Forensic Document Examination, it involves the application of scientific
methods and principals for document examination. This helps to produce
evidence about a questioned document that is admissible in the court of
law to prove its legitimacy.
3. Section-47 INDIAN EVIDENCE ACT
When the Court has to form an opinion as to the person by whom any document was written or
signed, the opinion of any person acquainted with the handwriting of the person by whom it is
supposed to be written or signed that it was or was not written or signed by that person, is a
relevant fact.
Explanations
A person is said to be acquainted with the handwriting of another person when he has seen that
person write, or when he has received documents purporting to be written by that person in
answer to documents written by himself or under his authority and addressed to that person, or
when, in the ordinary course of business, documents purporting to be written by that person
have been habitually submitted to him.
Illustrations
The question is, whether a given letter is in the underwriting of A, a merchant in London.
B is a merchant in Calcutta, who has written letters addressed to A and received letters
purporting to be written by him. C is B’s clerk, whose duty it was to examine and file B’s
correspondence. D is B’s broker, to whom B habitually submitted the letters purporting to be
written by A for the purpose of advising him thereon. The opinions of B, C and D on the question
whether the letter is in the handwriting of A are relevant, though neither B, C nor D ever saw A
write.
4. SECTION 29 INDIAN PENAL CODE
The word “document” denotes any matter expressed or described upon any substance by means of letters,
figures or marks, or by more than one of those means, intended to be used, or which may be used, as evidence of
that matter.
Explanations
It is immaterial by what means or upon what substance the letters, figures or marks are formed, or whether the
evidence is intended for, or may be used in, a Court of Justice, or not.
Illustrations
A writing expressing the terms of a contract, which may be used as evidence of the contract, is a document.
A cheque upon a banker is a document.
A power-of-attorney is a document.
A map or plan which is intended to be used or which may be used as evidence, is a document.
A writing containing directions or instructions is a document.
Explanations
Whatever is expressed by means of letters, figures or marks as explained by mercantile or other usage, shall be
deemed to be expressed by such letters, figures or marks within the meaning of this section, although the same
may not be actually expressed.
Illustrations
A writes his name on the back of a bill of exchange payable to his order. The meaning of the endorsement as
explained by mercantile usage, is that the bill is to be paid to the holder. The endorsement is a document and must
5. HANDWRITING IS UNIQUE
Handwriting: A person’s individual style of writing with an
implement (pen, pencil, etc.)
• -Based on the premise that handwriting is unique to an individual
• -Subconscious behavior
• -As one become more proficient in writing, one will develop their own
personal style
This will present more distinguishable features & leads
experts to believe that handwriting may be as individual as
our fingerprint

7. Common Types of Questioned Documents
Subjected to Forensic Document
Examination
At present, every other person is adept at using Adobe Photoshop, Acrobat
and other visual editing software. This has made document forgery a
cakewalk for individuals with corrupt intentions. The properties of a
questioned document that are examined include handwriting, signatures,
and typewriting.
Sometimes even documents that do not bear any visible mark is subjected
to forensic document examination. For example, documents kept below
other documents while writing may contain impression evidence.
Even burned or shredded documents can give significant leads to an
investigation if they are reconstructed.
8. COMMON TYPES OF QUESTIONED
DOCUMENTS SUBJECTED TO FORENSIC
DOCUMENT EXAMINATION ARE
• Wills
• Cheques
• Bank Drafts
• Agreements
• Receipts
• Laminated Documents
• Photocopied Documents
• Stamp Papers
• Passports
• ID Cards
• Licenses
• Currency notes
• Suicide notes
9. TYPES OF FORENSIC DOCUMENTS
SPECIMEN WRITING – Specimen writing refers to any signature or
handwriting taken by any suspect or deceased in presence of the
investigating officer
ADMITTED WRITING – Admitted writing refers to any writing or signature
that the individual admits or writes during its daily course of time.
EXAMPLE – Normal bank withdrawal slip, official document
QUESTIONED DOCUMENT – Questioned writing refers to any handwriting
or signature whose authenticity is under doubt.
10. CRIMES RELATED TO QUESTIONED
DOCUMENT
• Identity Theft
• Forgeries
• Counterfeiting
• Suicides
• Homicides
• Fraud
• Kidnappings
• Bank Robberies
• Contested Wills
• Extortion
• Medical Malpractices
• Stalking
• Title/Deed Lawsuits
• Contested Contracts
Handwriting examination enables document
examiners to distinguish a forged handwriting from
the genuine one. This helps them confirm or exclude
suspects from the investigation.
11. RULES OF HANDWRITING
RULES OF HANDWRITING WERE GIVEN BY ORDWAY HILTON
1) The handwriting of every mature writer is personal and individual to him alone.
2) It is impossible for a person to produce exactly same that has been written first. There must be a natural
variation in the writing of the same person.
3) From the above principle, it is a fact that one cannot write two signatures precisely alike.
4) If two of signatures are alike then one of them is forged.
5) Every person’s writing undergoes gradual changes in the course of life, however, in most of the cases the
changes are very slow and they may not be discernible.
6) Two different persons cannot write in similar style.
7) A writer cannot exceed his writing skill and ability unless he makes serious efforts and practice.
8) A person cannot adopt different styles of writing at different times, as to change one’s normal style of
writing us an exceeding difficult task.
9) A disguise is always superficial. Disguise leads to an inferior quality of writing.
10) The attempt of disguise in most of the cases is simple in nature.
12. CLASS CHARACTERISTICS
Class characteristics of natural genuine handwriting refers to those characteristics
that are common among the writing of all the individuals who happened to learn
the same system of writing forms every individual introduced some personal
modifications but substantially the base form remains the same.
Line Quality
Size Consistency
Shading
Skills
Connecting Strokes
Alignment
Slant
Punctuation
13. INDIVIDUAL CHARACTERISTICS
These are created by individual consciously or unconsciously by
modifying the copybook writing forms of letter digits etc.
The problem arises only when the writer of question the document
is unknown and more than one sample / standard are available for
the purpose of comparison to narrow down the list of suspects.
These specimens are also called examples every mature writer has
its unique handwriting which has its own unique identifying
characteristics these characteristics are different from most of the
others .
Skill Level
Slant or inclination
Form
Movement
Proportions/Symmetry
Height Ratio

15. Questioned Document Analysis by Document
Examiners
Document examiners use scientific principles of handwriting and ink
analysis for examining the different types of questioned documents.
Questioned Document Analysis by document examiners includes
handwriting examination and the analysis of several other features of
the questioned document.
SIGNATURE & HANDWRITING EXAMINATION
Handwriting and signature are unique to a particular individual. This
makes it possible for document examiners to identify forgery or
alterations. Document examiners trained in handwriting and signature
analysis are thus able to identify a forged handwriting/signature from a
genuine one.
16. Examination of Printers, Fax Machines, Typewriters and Photocopy
Machines
In the case of typewritten questioned documents, Document Examiners go to the extent of examining
the very machines that produced them. For instance, a typewriter output always has certain exclusive
properties. Some of these properties are the same for a particular model of the machine –
electric/manual, carbon film ribbon/fabric ribbon etc. Typewriters, printing or photocopy machines also
produce unique properties on its output depending on its abuse, damage, wear and tear.
17. Ink Examination
Document examiners sometimes use liquid chromatography to extract
samples of ink from a questioned document for analysis. Other methods of
ink examination include subjecting the questioned document to infrared
radiation. This helps identify forged documents because different inks react
differently when exposed to different frequencies of infrared light.
18. Detection of Indentation
Documents recovered from a crime scene or a suspect may also give
crucial leads from impression evidence or indented writing. Certain
documents do not contain any distinguishing mark or note. However, when
analyzed with an Electrostatic Detection Device (EDD), they reveal certain
invisible impressions or indentations. These could help establish crucial
links between a suspect and the crime.
19. Detection of Deletions, Erasures
and Other Alterations
Forensic Document Examination can reveal for evidence of alterations, obliterations, erasures
and page substitutions. Such changes that are not visible to the naked eye can be
detected using photography and UV/IR imaging devices. Imaging instruments such as
a Video Spectral Comparator (VSC) use radiations of different wavelengths to identify
additions, erasures or alternations. This is possible by the different reactions of different inks
to varied wavelengths of light.
20. COUNTERFEITING
Counterfeiting is a crime of making an
unauthorized imitation of a genuine article,
typically money, with the intent to deceive or
defraud. Counterfeit money is currency that is
produced without the legal sanction of the state or
government.
Counterfeit money is imitation currency produced
without the legal sanction of the state or
government, usually in a deliberate attempt to
imitate that currency and so as to deceive its
recipient. Producing or using counterfeit money is
a form of fraud or forgery.

25. INDIAN PASSPORT
Regular passport (Deep Blue) - Issued to regular citizens for ordinary
travel, such as for vacation, study and business trips (36 or 60 pages). It is a
Type "P" passport - P stands for personal.
Official passport (White cover) - Issued to individuals representing the
Indian government on official business. It is a Type "S" passport - S stands
for Service.
Diplomatic passport (Maroon cover) - Issued to Indian diplomats, top
ranking government officials and diplomatic couriers. It is a Type "D"
passport - D stands for Diplomat.
26. SECURITY FEATURES OF INDIAN PASSPORT
There are a number of Security Features which are currently present
in the Indian Passports. Both GIP (Genuine Indian Passport) and
FIP(Fake Indian Passport) can be distinguished with each other on
the basis of Security Features.
In the current research work all the Security Features present in the
passport is discussed below. All these Security Features can be
viewed under different light source in UV Light [365nm (long-wave
UV), 312 nm (medium wave UV) and 254 nm (shortwave UV)], Visible
Normal Flood Light, and Infrared/Spot Light as well as in Transmitted
Light & Oblique/Side Light.

31. Handwriting
Examination
Document Examiners involved in handwriting examination
divide handwriting samples into two types – Collected
Writing Specimens and Requested Writing Specimens.
Collected Writing Specimens are handwriting samples of the
subject, collected from the site or crime scene prior to the
investigation.
Requested Writing Specimens are writings that are dictated
to the subject (writer) by the investigator. Such specimens
are purposely created under controlled conditions for the
purpose of handwriting examination. It involves a close
monitoring of the writer by the investigator and/or document
examiner.
Documents such as letters, diaries, canceled cheques,
medical records, business contracts or other legal
documents containing a signature are good sources of
writing samples.
Handwriting Examination involves the analysis of several
handwriting characteristics such as letter and word spacing,
speed, the position of the pen, capitalization, slope/slant,
legibility and many other attributes.
34. IMPORTANT
CONTRIBUTION
Albert Sherman Osborn is considered the father of the science
of questioned document examination in North America.
His book Questioned Documents was first published in 1910 and later
heavily revised as a second edition in 1929. Other publications,
including The Problem of Proof (1922), The Mind of the Juror (1937),
and Questioned Document Problems (1944) were widely acclaimed
by both the legal profession and by public and private laboratories
concerned with matters involving questioned documents.
Osborn is also known for founding the American Society of
Questioned Document Examiners (ASQDE) on September 2, 1942. In
1913 Osborn began inviting select practitioners to informal
educational gatherings hosted in his home and those meetings
eventually led to formation of the ASQDE. He became the society's
first president and was involved intimately with the discipline and
Society until his death four years later.
