  • More developed procedures are generally characterised by that the dermatoglyphic patterns are stored in information recording equipment, so that they can be evaluated by a computer technology device, in a data store containing a large amount of data, and the pattern intended to be compared is compared to the data placed in this store earlier

Abstract

L'invention concerne l'accélération de la comparaison de configurations dermatoglyphiques, en particulier, d'empreintes palmaires et digitales, ce qui consiste à créer des groupes basiques de signes, pouvant être traités par le dispositif de comparaison, par exemple, des particularités, des configurations principales d'individus appartenant à un groupe primaire et à produire un ensemble de référence à partir d'un agrégat de certains groupes basiques de signes, puis à recueillir cet ensemble, en se basant sur les parties porteuses d'informations des configurations à examiner, dans un groupe ciblé, correspondant aux éléments porteurs d'informations des configurations principales, à créer des groupes de signes soumis à investigation et pouvant également être traités par le dispositif de comparaison et à comparer, à l'aide de ce dispositif de comparaison, les groupes de signes soumis à investigation avec les groupes basiques de l'ensemble de référence, à enregistrer le résultat de l'analyse et à créer à partir de ce résultat des indicateurs de rapport, et enfin à produire un ordre de rapport par mise en relation des groupes basiques de signes de l'ensemble de référence avec les indicateurs de rapport. L'invention est caractérisée par le fait qu'en dehors de créer les groupes de signes (22) soumis à investigation des configurations à examiner (21), elle permet également de créer des groupes de signes exclus (33) pouvant être traités par un dispositif de comparaison supplémentaire (50) et concernant les éléments porteurs d'informations (32a), par exemple, les particularités, des configurations vivantes (32) de personnes (31) appartenant au groupe exclu (30), ce qui consiste à comparer d'abord les groupes de signes (22) soumis à investigation des configurations à examiner (21) aux groupes de signes exclus (33) des configurations vivantes (32) à l'aide du dispositif de comparaison supplémentaire (50) et à supprimer des configurations à examiner (21) les groupes de signes (22) de la paire de ces signes (22) soumis à investigation et les groupes de signes exclus (33) au cours de la comparaison, ce qui permet de limiter le nombre des configurations à examiner (21) par création d'un ensemble de configurations (40) examinées au préalable, seuls les groupes de signes (22) soumis à investigation et introduits dans l'ensemble de configurations (40) examinées au préalable étant comparés aux groupes basiques de signes (12) de l'ensemble de référence (13).
