The occurrence of famous fingerprint identification errors,such as the McKie case in the UK and the Madrid train bombing case in Spain,has triggered an increase in the scientific requirements for fingerprint evidence,and the industry is in urgent need of basic theoretical research on close non-matches(CNMs).In addition,with the continuous expansion of the fingerprint database,the fingerprints screened by automatic fingerprint identification system with the highest scores are highly similar to the fingermarks,and the identification risks brought by CNMs are constantly amplified.The problem of CNMs has become one of the important research contents in the field of fingerprint inspection,which is of great significance to the construction of fingerprint identification standards.In this paper,firstly,the research background of CNMs is expounded with the Madrid train bombing case.Secondly,the concept of CNMs and a peer-reviewed standard are introduced.Then,the causes of CNMs(mainly monozygotic twins and automatic fingerprint identification system),the false positive error rate and the causes of identification errors are comprehensively and deeply analyzed and summarized.Finally,combined with the research status,some prospects for its future development trend are put forward,with a view to supplementing the basic theory of fingerprint identification and providing some reference for the quantitative evaluation of fingerprint evidence.
