Mit bildbasierten Passwörtern zum CAST-Preis: Ulmer Student entwickelt innovatives System für Mobiltelefone

(PresseBox) (Ulm, )
Handy, Computer, Facebook....täglich nutzen wir zahlreiche Text-Passwörter. Die Chance durcheinander zu kommen, ist dementsprechend hoch. Abhilfe schafft jetzt die "App" Picpass: In seiner Bachelorarbeit hat der Ulmer Informatikstudent Daniel Ritter das bildbasierte Passwortsystem MIBA (Multitouch Image Based Authentication) entwickelt und mit einem Passwortsafe kombiniert. Für diese Innovation hat der 24-Jährige jetzt den mit 3000 Euro dotierten "Förderpreis IT-Sicherheit" des "Competence Centers for Applied Security Technology" (CAST) erhalten.

Das MIBA-Prinzip ist einfach: Der Besitzer eines internetfähigen Mobiltelefons ("Smartphone") wählt auf hintereinandergeschalteten Bildern markante Punkte aus. In einer Straßenszene also etwa Plakatwand, Laterne und Taxi.
