The notion of remote biometric identification system as used in this Regulation should be defined functionally, as an AI system intended for the identification of natural persons typically at a distance, without their active involvement, through the comparison of a person’s biometric data with the biometric data contained in a reference data repository, irrespectively of the particular technology, processes or types of biometric data used. Such remote biometric identification systems are typically used to perceive (scan) multiple persons or their behaviour simultaneously in order to facilitate significantly the identification of a number of persons without their active involvement. Such a definition excludes verification/authentication systems whose sole purpose would be to confirm that a specific natural person is the person he or she claims to be, as well as systems that are used to confirm the identity of a natural person for the sole purpose of having access to a service, a device or premises. This exclusion is justified by the fact that such systems are likely to have a minor impact on fundamental rights of natural persons compared to remote biometric identification systems which may be used for the processing of the biometric data of a large number of persons. In the case of ‘real-time’ systems, the capturing of the biometric data, the comparison and the identification occur all instantaneously, near-instantaneously or in any event without a significant delay. In this regard, there should be no scope for circumventing the rules of this Regulation on the ‘real-time’ use of the AI systems in question by providing for minor delays. ‘Real-time’ systems involve the use of ‘live’ or ‘near-‘live’ material, such as video footage, generated by a camera or other device with similar functionality. In the case of ‘post’ systems, in contrast, the biometric data have already been captured and the comparison and identification occur only after a significant delay. This involves material, such as pictures or video footage generated by closed circuit television cameras or private devices, which has been generated before the use of the system in respect of the natural persons concerned.
