The ethical dimension of Artificial Intelligence. Biometric identity and human behaviour

The debate over the ethical repercussions of Artificial Intelligence (AI) cannot disre-gard the “sum total of ideas that bring into evidence a system of ethical reference that justifies that profound dimension of technology as a central element in the attainment of a ‘finalized’ perfection of man”(Galvan 2001). This implies an analysis of the an-cient processes that might help to understand the complexities of contemporary so-ciety and the new challenges posed to human development. Being at the core of the dichotomy between the human and the machine, biometrics will be central to the analysis carried out in this paper. Its measurement of physiological characteristics and behavioural patterns has politico-philosophical and legal consequences in terms of recognition and personal identity, as the use of artificial intelligence has shown. In information society, customs and traditions, cultural and communication processes, language and the self-determination of the individual have gradually acquired a stretched dimension that has led to a re-definition of the social structures within which the exchange of knowledge and data takes place, with AI-based technological devices playing a key role in such a scenario. The issue of biometric identity becomes highly complex when combined with thepotential of digital services, as it is at this level that it shows the large number of interconnections deriving from social and po-litical choices. The benefits of increased interconnection are limited by the risk of intrusion into the (social, personalor private) human sphere, which might pose a threat to both the physical, biological body, with its related freedoms (habeas corpus), and the digital body, in its multiple forms and media representations (habeas data).
