Data Publications

1. Digital Corpora Scenarios (2008-), forensic data from working systems but created by investigators according to scripts so that the images do not contain identifiable private information from actual persons. As such, IRB approval is not required. These images can be freely downloaded from https://digitalcorpora.org/. Teachers guides are available.
2. The Real Data Corpus (2005-2015), a collection of raw data extracted from data-carrying devices that were purchased on the secondary market around the world. Many studies have shown that hard drives, cell phones, USB memory sticks, and other data-carrying devices are frequently discarded by their original users without the data first being cleared or purged. By purchasing these devices and extracting their data, we have created a data set that closely mimics data as it is found in the real world.
3. GOVDOCS1 (2009), a collection of roughly 1 million files that have been characterized and are available for download and open use. By collecting documents already made publicly available by the US Government, this corpus avoids copyright and privacy issues.
