Fingerprints are frequently encountered during both civil and criminal investigations. Fingerprints possess numerous characteristics that assist with personal identification. Determining the hand of origin (right or left) for an individual fingerprint would help reduce investigation time and potentially eliminate certain suspects. In this study, we collected a total of 2 900 single digit fingerprints from 290 individuals, and the whorl axis slant was examined in the 743 whorl pattern fingerprints (385 from the right hand and 358 from the left hand). A slant towards the right side was present in 81.82% of samples from the right hand, while a slant towards the left side was observed in 80.73% of samples from the left hand. After applying a chi-square test to the dataset, the results were found to be statistically significant for the determination of hand origin. Our results suggest that the whorl axis slant in a fingerprint is indicative of hand origin (right or left).Key pointsSingle digit fingerprints with whorl pattern were analyzed.Whorl "axis slant" was used to determine the hand origin.Right axis slant would indicate the right hand of the print.Left axis slant would indicate the left hand of the print.
在民事和刑事调查中，指纹经常会被遇到。指纹具有许多有助于个人识别的特征。确定单个指纹的起源手（右手或左手）将有助于缩短调查时间，并有可能排除某些嫌疑人。在本研究中，我们从290个人那里总共收集了2900个单指指纹，并对743个斗型纹指纹（右手385个，左手358个）的斗轴倾斜度进行了检查。右手样本中有81.82%呈现向右倾斜，而左手样本中有80.73%呈现向左倾斜。对数据集应用卡方检验后，发现结果对于确定起源手具有统计学意义。我们的结果表明，指纹中的斗轴倾斜度可指示起源手（右手或左手）。要点分析了具有斗型纹的单指指纹。使用斗“轴倾斜度”来确定起源手。向右轴倾斜表明指纹来自右手。向左轴倾斜表明指纹来自左手。
