• One of the problems faced by fingerprint identification is a dificulty to estimate its degree of uncertainty. A computer program has been developed in order to help solve this problem. By means of this application, it has been possible to create a database of characteristic points that consists of about ten thousand dactylograms. The dactylograms are evenly distributed by sex, finger and fingerprint type. Morphology has been taken into account, as well as the orientation and location of points taken as valid in order to perform a survey of said database, the purpose being to find out any correlations between the distribution and frequency of characteristics points, which might have an impact on the calculation of cumulative frequencies. Additionally, a methodology has been designed that makes it possible to estimate the descrimination rate in edentifications
