The DFIQI is a software application originally developed by employees of the United States Government and provides a measure of the quality of friction ridge skin impressions.
The DFIQI software is a quality assessment software for friction ridge skin impression evidence. It measures the clarity of friction ridge impression minutiae and provides a quantitative assessment of the overall quality of an impression for comparison and evaluation purposes as it relates to determinations of Value, Complexity, and Difficulty of the impression during the Analysis phase of the examination methodology. The results provide an empirical foundation to experts’ opinions and an efficient framework for strengthening quality assurance protocols.
The technical publication in Forensic Science International provides comprehensive details regarding the development and validation of DFIQI.
