Biometrics are distinguished into physiological, biological and behavioural features of human beings. Their inherently given und unchangeable information -each associated with strength and weaknesses- are particularly suitable for the process of human authentication. Moreover, biometrics are (often) cryptographically stronger than traditional authentication because they contain significantly more information. Modern approaches turn biometric methods attractive again and become a current field of research:  Examples: Gait-based Authentication:  The human gait is influenced by physiological and pathological conditions. Factors such as stride length, foot size and weight are considered as well. ECG-based Authentication:  The electrocardiogram is the recording of the electrical activity of the heart. Based on the size, position and orientation of the heart, combined with the age, sex and bodyweight of the individual, each wave contains unique features. Voice authentication: The Voice authentication (VA) is based on the phonetic and morphological features of individuals, combined with the varying size of vocal fold and larynx, which give the voice its uniqueness.
