Abstract: The digital revolution is causing a paradigm shift in writing tools. Handwriting can be digitally captured using a variety of tools with different features. A forensic handwriting examiner (FHE) may come across such kind of handwriting for examination. Digitally captured handwriting (DCH) provides qualitative as well as quantitative information about the dynamics of the handwriting process. Several frameworks and methods are suggested for analysing digitally captured handwriting and signatures. This review has explored the most recent advancements and challenges in the forensic analysis of dynamic handwriting and signatures. The majority of DCH research focuses on automatic handwriting verification or recognition through algorithms, but none of it considers a forensic perspective. Additionally, the generalised framework for forensic analysis of digitally captured handwriting or signatures is inadequate, and a standard framework must be established.

Keywords: forensic examination; handwriting; signature; dynamic signatures; forensic handwriting examiner; FHE.
