1. Handwriting and Specimen Signature Forensics By CA Sukumar Basu Research Paper on Handwriting and Specimen Signature Forensics

2. Research Paper on Handwriting and Specimen Signature Forensics Overview: This document is intended to serve as an approach to forensic handwriting examination for practitioners actively involved in casework, or for those interested in investigating general aspects of the practice of forensic handwriting examination . Like fingerprints, every person’s handwriting is unique and personalized. Handwriting is difficult to disguise or forge and analysis can provide a useful tool in forensics in excluding persons when determining a match between known materials (exemplar). CA Sukumar Basu

3. Research Paper on Handwriting and Specimen Signature Forensics Everyone’s handwriting exhibits natural variation due to several factors. Adults show slight variation because the characters are formed as a result of habit and their brain has been trained. A Signature is a combined result of cumulative effect of a number of factors such as muscular control, co-ordination, health, age, frequency of writing, temperature etc. Formal Signatures- Used on wills or other important documents. Informal Signatures- used on routine documents and personal corresponding. Careless Scribble- used for signing credit cards, mail deliveries, autographs, or hotel registration forms. CA Sukumar Basu

4. Research Paper on Handwriting and Specimen Signature Forensics Authentic Signature i s the combination of writing characters which are consistent with natural conditions surrounding the signed document. Characteristics of Authentic Signatures and Writing Written rapidly. Have Rhythm when written by experienced writer with proper health. May miss certain information. Introduce certain other forms. End Strokes Flourish. Smooth. Natural free flowing Appearance. CA Sukumar Basu

5. Research Paper on Handwriting and Specimen Signature Forensics Forged Signatures are practiced illegally and are not genuine are termed as forged signatures. Characteristics of Forged Signatures and Writing Appearance of being slowly written. Lack of Rhythm and Individuality. Unnatural Appearance. Appearance of being drawn. Attention towards formation of letters. CA Sukumar Basu

6. Research Paper on Handwriting and Specimen Signature Forensics Types of Forgeries Simple Forgery: the forger does not imitate the signature of the other person but he simply signs his own signature without any intention to imitate. Traced Forgery: the forger traces the original signature on the other document. This may be done with Carbon tracing, Simple tracing or Using transmitted light methods Simulated or Freehand Forgery: the forger practices the genuine signature and tries to imitate the same signature on the other document. Transplanted forgery: it is usually done on the stamps. CA Sukumar Basu

7. Research Paper on Handwriting and Specimen Signature Forensics Theory of Handwriting: Handwriting is an acquired skill. It is, therefore, a habitual as well as individualized; this individualization is basic principle in document examination. Most of the hand muscles are situated in the lower arm and connect to the fingers by an intricate set of tendons. Their ability in manipulating a writing instrument is precisely coordinated by a timing system under a neural controls of movements of the arm the hand and the fingers. CA Sukumar Basu

8. Research Paper on Handwriting and Specimen Signature Forensics Questioned Document Examination: When a question is raised about the authenticity of a document or a part thereof, that document becomes a questioned document, which is sometimes also referred to also ‘disputed’ or contested’ document. Following types of identification are regularly done in handwriting and signatures: Is the handwriting Genuine or Forged? Is the signature Genuine or Forged? Authorship of the Handwriting and Signatures? Is the A Handwriting Disguised? Is the Handwriting transplanted? CA Sukumar Basu

9. Research Paper on Handwriting and Specimen Signature Forensics Basic Principles of Handwriting and Signature Identification The basic philosophy behind Handwriting Identification is comparison of class and Individual characteristics of the given handwriting sample. The first step is to observe the general appearance of the questioned writing as compared with the genuine standard writing. By this method the conspicuous characteristics are determined. CA Sukumar Basu

10. Research Paper on Handwriting and Specimen Signature Forensics Forensic Handwriting and Signature Identification Handwriting Identification is completely based on the comparison of class and individual characteristics. It is similar to that of fingerprint Identification. Characteristics such as bifurcation, Island, Dot, Short ridge, Core, Delta etc. are compared in fingerprint identification. Similarly there are class and individual characteristics in handwriting comparison. CA Sukumar Basu

11. Research Paper on Handwriting and Specimen Signature Forensics The Process of Handwriting and Signature Identification Document analysis – examination and comparison of questioned documents with known material. Experts establish the authenticity of the documents and detect any changes, erasures, or obliterations that may have occurred. Questioned documents – signature or handwritings whose source or authenticity is in dispute or uncertain. Examples: checks, certificates, wills, passports, licenses, money, letters etc. Document Expert – specially trained person who scientifically analyzes handwriting and other features in a document, often to detect changes from the original. CA Sukumar Basu

12. Research Paper on Handwriting and Specimen Signature Forensics Discussion and Conclusion This paper is an approach to characterize handwriting and signature in forensic point of view. The detailed characters discussed on handwriting and signatures analysis are essential to eliminate a suspected signature or handwriting. The alterations made in the documents are also a kind of forgery so their examination and detection also becomes a very major aspect of forensic examination. The forensic handwriting examiners have ample knowledge about the class and individual characters used to identify handwriting. Hence forger must now think twice before he damages the document.
