Abstract :
Nowadays World Wide Web makes use of Human Interactive Proofs and CAPTCHA to distinguish legitimate users from bots. This paper presents an overview of current systems and their weaknesses and proposes a unified theory for a multilingual handwriting CAPTCHA. We further describe our French and Spanish CAPTCHAs, as an extension to the English version, with the potential of being more useful on websites in those languages. Highly interdisciplinary techniques used to generate our CAPTCHAs are also discussed.
