Statistical methods for digital image forensics: Algorithm mismatch for blind spatial steganalysis and score-based likelihood ratios for camera device identification

Type: , Research Area(s):

Published: 2020 | By: Stephanie Reinders

Forensic science currently faces a variety of challenges. Statistically suitable reference databases need to be developed and maintained. Subjective methods that can introduce bias need to be replaced by objective methods. Highly technical forensic methods need to be clearly and…

Bayesian hierarchical modeling for the forensic evaluation of handwritten documents

Type: , Research Area(s):

Published: 2020 | By: Amy Crawford

The analysis of handwritten evidence has been used widely in courts in the United States since the 1930s (Osborn, 1946). Traditional evaluations are conducted by trained forensic examiners. More recently, there has been a movement toward objective and probability-based evaluation…

Mock Jurors’ Evaluation of Firearm Examiner Testimony

Type: Research Area(s):

Published: 2020 | By: Brandon L. Garrett

Objectives: Firearms experts traditionally have testified that a weapon leaves “unique” toolmarks, so bullets or cartridge casings can be visually examined and conclusively matched to a particular firearm. Recently, due to scientific critiques, Department of Justice policy, and judges’ rulings,…

Probabilistic Reporting in Criminal Cases in the United States: A Baseline Study

Type: Research Area(s):

Published: 2020 | By: Simon Cole

Forensic evidence reporting shows a high degree of adherence to prevailing disciplinary standards.  Probabilistic reporting of forensic results remains rare.  Probabilistic reports were mostly subjective verbal assignments of posterior probabilities.
