Biometrische Verfahren werden häufig im Rahmen der Authentifizierung zum Schutz wichtiger Daten und Systeme eingesetzt. Hierzu werden biometrische Referenzen gespeichert, die Informationen über biometrische Charakteristika der betroffenen Individuen enthalten. Um diese biometrischen Referenzen in offenen und verteilten ...

Biometric gait recognition is a well suited method for authentication on mobile devices as it is unobtrusive and concurrent. Hence, in contrast to PIN authentication it is no extra-effort for the user. The characteristic gait of a subject can be recorded using accelerometers which are nowadays already contained in many ...
