Application of probalistic reasoning in fingerprint casework

Application of probalistic reasoning in fingerprint casework Open Inschrijving (internationaal)

Workshop The Netherlands Forensic Institute (NFI) organizes a two-days workshop at the NFI on the current probabilistic approach as applied by the WOVI team of the NFI. This workshop, taught by the WOVI-team of the NFI, focuses on the method itself, the reasons behind it and how it is used in casework. Software tools that are used to explore our dataset will be demonstrated. In the preparative materials an introduction to Bayesian Reporting, in which the Likelihood ratio method is explained, is offered as an e-learning.

Inhoud

During the course you will have the opportunity to make acquaintance with the LR method as applied at the NFI. You will receive hands-on exercises developed for this course:

  • You will be performing comparison exercises
  • You will be trained on using our tables, graphs and other data to underpin your verbal Likelihood ratio
  • A demonstration will be given of the Automated Feature Evaluation Software (AFES) to assess the evidential value

Target group
Fingerprint investigators from the police or a forensic institute

Objectives
Once you have successfully completed the workshop you:

  • Will have gained insight in the current probabilistic approach as applied by the WOVI team of the NFI (how do we do it?)
  • Will understand the reasons behind the choice for a probabilistic approach of fingerprint evidence (why do we do it?)
  • Will have been shown multiple NFI case-examples using examples of fingermarks that were concluded as fit or not fit for a probabilistic interpretation.
  • will have gained insight in how to arrive at a verbal expression of the evidential value.
  • will have been shown how NFI WOVI applies a frequency model on fingermark comparisons.
  • will have been shown which software tools were developed in order to analyse the NFI dataset in order to extract frequencies for fingerprint patterns, core-delta distances and minutiae types.
  • Will have performed comparisons exercises
  • Will have trained the use of the verbal scale
  • Will have trained to find the relevant data to underpin your verbal expression of the LR
  • will have received a demonstration on the Automated Feature Evaluation Software (AFES) to underpin your chosen verbal expression of the LR
