摘要
目的针对指纹鉴定常用的5类纹型所占的概率、4类细节特征点所占的概率及4类细节特征点组合概率,探讨用数字计算出指纹鉴定结论相同概率的方法。方法取已破案件被比中人员中具有5类纹型及4类细节特征点的指纹1000人份,分为10组,每组100人份进行概率分析。结果指纹的5类纹型、4类细节特征点及组合概率存在稳定的规律。结论可以数字化描述指纹鉴定结论。
Based on a sample of 10000 fingerprints from 1000 individuals, the frequencies of five patterns and four minutiae characteristics have been analyzed statistically. The author suggested that these frequencies can be used for probability conclusion of fingerprint comparison.
