Abstract

Handwriting has been proposed as a possible biometric for a number of years. However, recent work has shown that handwritten passphrases are vulnerable to both human-based and machine-based forgeries. Pseudosignatures as an alternative are designed to thwart such attacks while still being easy for users to create, remember, and reproduce. In this paper, we briefly review the concept of pseudo-signatures, then describe an evaluation framework that considers aspects of both usability and security. We present results from preliminary experiments that examine user choice in creating pseudo-signatures and discuss the implications when sketching is used for generating cryptographic keys.
