Abstract:This paper presents and systematically evaluates the first masterkey attack against free-text keystroke dynamics. A masterkey is a typing sequence that matches, hence successfully impersonates, a large part of the population. Therefore, masterkeys are effective tools for an adversary who aims to impersonate someone without knowledge of their typing behavior. On top of the attack itself, we present a new unifying evaluation framework for masterkey attacks that allow for the comparison with knowledge-based authe… Show more
