The paper contains an overview of security and forensic identification kinds through the ages. The systemization of the concepts, principles and methods of identification can be carried out according to various criteria with regard to the possibilities of the use of new information and communication technologies which enabled the application of the system access and biometric identification. Identification in terms of determining the identity and using the results of identification while proving an offence in criminal proceedings has the most general sense, however, the need for identification of various kinds of security activities cannot be overlooked either.
