Title: Approximate Matching: Definition and Terminology
Published: July 02, 2014
Abstract: This document provides a definition of and terminology for approximate matching. Approximate matching is a promising technology designed to identify similarities between two digital artifacts. It is used to find objects that resemble each other or to find objects that are contained in another object. This can be very useful for filtering data for security monitoring, digital forensics, or other applications. The purpose of this document is to provide a definition and terminology to describe approximate matching in order to promote discussion, research, tool development and tool acquisition.
