Forensic Analysis of Electronic Signatures
Heidi H. Harralson · Routledge eBooks · 2013
The forensic examination of digital and electronic signatures and handwriting is reviewed and discussed. There are forensic challenges associated with electronic interpretation of signatures from both hardware and software perspectives including the way signers approach electronic devices, and how devices and computerized digital capture can alter natural handwriting. The diverse technology used for signature capture including poor and high-quality resolution capture methods presents challenges in forensic analysis. The need for standardization in electronic signature examination is recognized, so forensic handwriting examiners may need to approach some types of electronic signatures conservatively. Recommended methods and standards for the forensic examination of electronic signatures are introduced. A recent court case involving a disputed electronic signature is reviewed as it highlights the challenges facing document examiners in the courtroom when examining and testifying about electronic signature cases.
