Collecting Biometric-based Crime Evidence

Silmultaneous with the advancement of science and technology, criminals’ methods and tactics get more complicated, too and police should equip itself with the world’s latest technology to extricate from this challenge. One of these technologies is biometrics which enables police to take giant steps in collecting crime evidence. The present research is of applied type in terms of kind and objective with a qualitative approach. The study society includes elite and experts with a sample mass of eighteen people to the saturation level using targeted sampling method and the collection tool includes semi-structured interviews in which the results of the interview were transcribed and encoded. The findings of this research indicated thatcollecting biometric-based crime evidence is possible in foiur deminsions (laboratories, field investigations, Web and cyber- management) where these dimensions are interrelated. According to the findings of this research, biometrics will augment police crime laboratories capabilities, particularly identity recognition laboratories which are in line with the most important function of biometrics and during course of police field investigations, the biometric technology will increase the police investigations domain in order to enable the police to obtain reliable evidence and be able to track in cyber domain and to provide  electronic surveillance with the help of biometrics and to collect crime evidence.
