Biometrische kryptografische Schlüssel

Abstract

Der Beitrag geht der Frage nach, ob und wie biometrische Eigenschaften (Fingerabdruck und Stimme) als "biometrischer Schlüssel" für die Kryptografie verwendet werden können. Dazu ist es wesentlich, Merkmale zu wählen, die sowohl über ausreichende Entropie als auch genügend "Stabilität" verfügen, um die Wiedergewinnung des Schlüsselmaterials sicher zu stellen.

An automated procedure for identification of a person using gait analysis

“…Currently, the preferred biometric techniques are fingerprints, iris scans, voice imprint, analysis of ears and face morphology, and motion analysis, which are some of the newest methods. 1 Biometrics can be used as a method for authentication, which is based on the measurement of physiological data or properties in relation to the behaviour of a person. 2 Behavioural characteristics are the characteristics that are very stable, and it is very difficult to change them intentionally because they are produced as a result of multiple inputs of conscious and subconscious activities such as voice colour, style of speech, body and movement of its parts during walking, writing style and signature.…”
