Digital forensics

Definition

Digital forensics is the process of collecting, preserving, analyzing, and presenting digital evidence in a manner that is legally admissible. It plays a crucial role in various fields, including law enforcement, cybersecurity, and data recovery, as it involves methodologies for recovering lost or deleted data and ensuring its integrity during analysis. This practice connects deeply with techniques such as laser scanning to create accurate digital representations of physical objects and environments, and with vocabularies that standardize terminology for cataloging cultural heritage assets.
