Document Forensics Laboratory

Researchers in the Document Forensics Laboratory (DFL) have developed cutting edge methodologies for the quantification and analysis of handwriting and for automated finger print matching. The DFL has partnered with Gannon Technologies Group in exploiting their graph-based handwriting technologies for multi-language document exploitation and biometric identification. The original technical concepts were developed to recognize handwriting in multiple languages and they ultimately proved to be very powerful pattern matching tools not only for handwriting but also fingerprints and other forms of impression evidence. The Lab has been staffed by statistics professors, research professors, postdoctoral research fellows and graduate research assistants.

DFL research has been reported at the 1st ACM Workshop on Hardcopy Document Processing 2004; the FBI Laboratories Forensics Lecture Series 2005; SDIUT 2005 The 2005 Symposium on Document Image Understanding Technology; SACH06 Summit on Arabic and Chinese Handwriting; AAAS 2006 Annual Meeting; EAFS 2006, EAFS 2009 and EAFS 2012 European Academy of Forensic Science Meetings; AAFS 2008, 2009 and 2010 Annual Meetings of the American Academy of Forensic Sciences, IAFS 2008 Triennial Meeting of the International Association of Forensic Sciences; ICFIS08 The Seventh International Conference on Forensic Inference and Statistics; and ROBUST2008 Robust Biometrics: Understanding Science & Technology held in Honolulu, Hawaii, November 2-5, 2008.

DFL researchers have a three-year grant (2010-2013) from the National Institute of Justice: Quantifying the Effects of Database Size and Sample Quality on Measures of Individualization Validity and Accuracy in Forensics.

DFL researchers gave three presentations on statistical methods at the National Institute of Justice (NIJ) Trace Evidence Symposium, Kansas City, August 2011. The presentations were: “Predictive Modeling for Determining the Discriminative Power of Trace Glass Evidence as a Function of the Number of Sampled Glass Fragments”; “ROC Curves for Methods of Evaluating Evidence: A Common Performance Measure Based on Similarity Scores”; and “On Parametric Models for Pairwise Comparisons with Applications to Estimation of Random Match Probabilities.”

DFL researchers gave four presentations on statistical methods at the National Institute of Justice (NIJ) Impression and Pattern Evidence Symposium (IPES 2012), Clearwater, FL, August 2012. The presentations were: “The story of an Academic/Commercial Partnership: developing a product for the Forensic Community”; “The Effect of the Order of Suspect and Background Population Samples on the Assessment of the Value of Evidence”; “Automated Statistically Ranked Latent-to-Reference Print Overlays”; and “A Note on the Value of Forensic Evidence for Sparse Categorical Tables.”

“The Forensic Language-Independent Analysis System for Handwriting Identification (FLASH ID),” was presented at the Measurement Science and Standards in Forensic Handwriting Analysis Conference & Webcast,” National Institute of Standards and Technology, U.S. Department of Commerce, June 4-5, 2013, Gaithersburg, MD.
