Grammar-based reduction for toolmark analysis

This study analyses PDF documents, employing a grammar-based reduction method with the intent of aiding examiners in identifying toolmarks left by the software that created the files. This research contributes to FDDE methodologies. Stored in this repository are the files that were subjected to toolmark analysis, the spreadsheets used to navigate them, and the most important scripts used to process them, as well as the compiled toolmark profiles for each of the tools that were specifically examined.
