Improving the Understanding and the Reliability of the Concept of "Sufficiency" in Friction ridge Examination

The goal of this project is to study the current accuracy, reliability and reproducibility of the determination of sufficiency for comparison and sufficiency for identification by fingerprint examiners; and proposes to develop training protocols, methods and quantifiable measures of sufficiency to supports operational decisions and source inferences made by examiners when comparing fingerprints. The scientific foundations of fingerprint identification will then be supported by a large scale testing or latent fingerprint examiners hand in hand with a systematic assessment of the weight of the features used during the ACE process. ca/ncf
