Signature Verification Forensics Test

Handwritten signatures are widely used in everyday life. It serves as the means of persons identification and intent. It is distinctive and unique for each person. Although it is unique, it can be forged. For example, banks use signatures to verify cheques; art museums use signatures to identify the respective owners, and in many such scenarios, handwritten signatures are used. Thus, authenticating signatures is extremely important. A signature verification forensics test is a biometric process used to verify writing features like writing movements, strokes, pressures & the type of writing instruments (pen or pencil) and substrate (ink) used in the respective documents.

What is Biometrics?

The word biometrics is associated with human traits or behavior, which can be measured & used for individual recognition. According to the personal traits considered, there are two types of biometrics:

  • Physical/Physiological – It considers the biological characteristics of users, like fingerprints, iris, face, hand, etc.
  • Behavioral – It considers dynamic elements such as voice, handwritten evidence, and particular expressions. Biometric systems offer enhanced security due to two main factors:
  1. Users do not have to memorize passwords or carry access keys,
  2. Genuine biometric data is difficult to steal, imitate, or generate

Signatures serve as identity verification; the same person’s signature varies due to various factors and conditions. It is found that signatures have three main attributes: form, movement, & variation, the movement being the most important. In addition, the experts found that slight variations occur over time once a signature style has been adopted. A genuine signature results from a lifetime of practice and habitual movement of the arm and wrist. On the other hand, forgery signatures result from handwriting, characterized by a conscious/purposive attempt to reproduce. Forensic tests for signature verification can identify these formations & curves and can declare them as genuine or fraudulent.

What Kinds of Documents are Analyzed for Signature Verification Tests?

With modernization, it is easy to create fraudulent documents by copying the handwriting or signature of a person. Therefore, the chance of cheating is more in all sectors, including business, legal, and finance. A signature verification forensics test can help in the following cases:

  • Extortion notes
  • Will documents
  • Suicide notes under question
  • Loan & mortgage documents
  • Property/Inheritance documents
  • Cheque & Stamp Analysis
  • Authenticity of Legal Documents
  • Forged business contracts
  • Counterfeiting, etc

Document Forgery And Its Signs

Forgery, also called white-collar crime, refers to the alteration of a document intending to defraud someone. It comes under section 465 IPC (Indian Penal Code) & shall be punished with imprisonment or with fine, or both. Now, how to spot document forgery? There are some key indicators of forged documentaries in signature verification tests:

  • Slow and methodical strokes – They are one of the most common signs of forgery. When people are writing in their style with their handwriting, the writing is done fast. When a person is copying a writing style or a signature, they usually do so slowly and methodically, trying to get everything right. Writing in this way creates very even strokes with little to no mistakes in how they write.
  • No variation in pen pressure – It is also one of the most common signs of forgery in a document. When one starts to write, they write quickly. You will notice hard & thick lines and light & thin lines in your text. If one tries to copy your writing or signature, they will form the characters more carefully, creating even lines with no variation in pen pressure.
  • An unnatural tremor – Tremors can happen because someone was nervous when writing. When one compares original handwriting to forged handwriting, one can spot a difference when an unnatural tremor is caused by stress, fear, a medical condition, or other factors.
