Abstract
Different countries have different norms of the number of minutiae considered necessary for identification in fingerprint comparison. Minutiae were investigated with respect to finger, pattern and hand in a sample of 100 Dutch males. The minutiae were counted in the 16 cells of a 20 .times. 20 mm grid placed on the fingerprint. Statistical analysis showed that individual-pattern- and fingerfactors determine the number of minutiae. In this quantitative respect the fingers of both hands can be grouped in 2 groups. Because an identification based on a fingerprint depends on the expected number of minutiae, this study draws special attention on the variation in this number. The number of minutiae needed for identification depends on finger, pattern, sex and population group of the individual.
