Automated firearm identification: on using a novel multiple-slice-shape (MSS) approach for comparison and matching of firing pin impression topography

摘要

Digital forensics is an advancing field that finds and infers original evidence in the form of electronic data. More precisely, digital crime scene analysis complements this data, providing security while recording, documenting, and processing, and overall information management. Firearm identification in digital crime scene analysis is an integrated part of digital forensics dealing with firing pin shape matching. This paper introduces a multiple-slice-shape (MSS) approach to accurately process the firearm toolmark surface data.
