Probabilistic approach of fingerprint evidence

Online workshop

The Netherlands Forensic Institute (NFI) organizes a one-day online workshop 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 methods it selves, the reasons behind it and how it is used in casework. The software tools that are used for it will be demonstrated. In the preparative materials an introduction to Bayesian Reporting is offered in an e-learning, in which the Likelihood ratio method is explained.

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.
