AUTHENTICITY AND ORIGIN

Questioned document examination is a discipline within forensic science that pertains to documents with disputed authenticity or origin. The primary purpose of the examination is to provide evidence about suspicious or questioned documents using a variety of scientific principles and methods.

Examiners inspect documents for the presence of alterations, obliterations, paper inconsistencies, and other signs of tampering. Through the course of the analysis, examiners can often reach a scientific determination of document origin and authenticity.

  • Handwriting & signatures
  • Surface features
  • Watermarks
  • Alterations
  • Use of different inks
  • Embedded invisible information
  • Latent images
  • Ink stamps
  • Tampering and photo-substitution
