Biometrics

Abstract: We live in a society that is increasingly interconnected, where communication between individuals is mostly mediated via electronic platforms, and transactions are often carried out remotely. In such a world, traditional notions of trust and confidence in the identity of those with whom we interact, once taken for granted, can be much less reliable. Biometrics, the scientific discipline of identifying individuals by measuring unique personal attributes, provides a reliable means of establishing or confirming an individual's identity. These attributes include facial appearance, fingerprints, iris patterns, voice, handwriting, and even the way we walk. The new technologies of biometrics have a wide range of practical applications, from securing mobile phones and laptops to establishing identity in bank transactions and travel.
