Open-source Data sets

CSAFE offers access to open-source datasets and databases for forensic scientists and forensic researchers to implement in their laboratories. They can also improve the statistical rigor of their evidence analysis techniques by using our datasets and databases as a guide. As you implement CSAFE open source forensic data into your work, please contact us with any questions or concerns that arise.

We also invite you to review CSAFE contributions to the NIST Ballistics Toolmark Database.

Pattern Evidence Data sets

Handwriting Database

A repository of 27 scanned writing samples from over 90 participants, making 2430 handwriting samples in total. In addition, survey data are available in a table format, including demographic variables and session specific information for each participant.

Shoe Outsole Impression Data Set

Images of 160 pairs of athletic shoes in two styles and four sizes. Participants wore the shoes for at least 10,000 steps per week, and images of the shoes were taken at five-week intervals, producing five observation points for each pair of shoes. 

2D Footwear Outsole Impression Data Set

A database of two-dimensional images of footwear outsole scans. There are 1,500 impressions from 150 pairs of used shoes. The information about the database contains the ID of the users, genders (for size), brands, models and sizes. 

Glass Elemental Data Set

Data on the chemical composition of float glass samples. The dataset includes 31 panes of float glass manufactured by Company A and 17 panes manufactured by Company B.

Bloodstain Pattern Data Set

A dataset of 61 blood spatter patterns scanned at high resolution, generated by controlled impact events corresponding to forensic beating situations. 

Digital Evidence Data sets

Stegoapp DB: Forensic Image Database

A dataset of over 960,000 innocent and stego images using 10 different phone models from 24 distinct devices, with detailed provenanced data such as a wide range of ISO and exposure settings, EXIF data, stego app, message information, embedding rate and other information.

Event-based Digital Forensics Datasets

Five datasets including email communications, mobile app usage, device location pings, web browsing and authentication.


Examiner Surveys

This dataset reports the findings of a survey of forensic fingerprint examiners to capture baseline data related to reporting practices across the discipline and practitioners’ attitudes and characterizations of probabilistic reporting.
