Abstract
Recent work has shown that certain handwriting biometrics are
susceptible to forgery attacks, both human- and machine-based. In this
paper, we examine a new scheme for using handwritten input that
attempts to address such concerns. Pseudo-signatures are intended to be
easy for users to create and reproduce while being resilient to
forgeries. Here we evaluate their feasibility in terms of usability and
security through several user studies. Our initial experiments suggest
that, when well-chosen, pseudo-signatures may prove to be an attractive
biometric, although more research is required.
