Method & Evidence

AimCan the integration of rare fingerprint minutiae features into standard matching algorithms improve the accuracy of forensic fingerprint identification?

MethodQuantitative analysis and algorithmic enhancement

ProcedureA novel method was developed to quantify the similarity between latent and tenprint fingerprint minutiae, using rare minutiae as reference points. This quantitative measure was then used to modify the similarity scores of existing minutiae-based matchers, thereby incorporating the impact of rare features. The enhanced system was tested on a forensic fingerprint database.
