A Visual Data Hash Method

Abstract

This report describes the Detector and Extractor of Fileprints (DEF) process for data protection and automatic file identification. The DEF process generates binary images from an arbitrary data file that are unique to the data file. These visual hashes, or fileprints as referred to herein, are based on spectral characteristics of the data. The DEF employs the patented Adjustable Bandwidth Concept Signal Energy Detector.
