Beyond Parasitic Authentication

Parasitic authentication [Ebringer et al., 2000] is a novel approach for user authentication in electronic wallet systems which combines security and usability. We propose an extension to parasitic authentication that integrates it to payment protocols thus increasing the security of electronic wallets. The additional security comes at the expense of greater complexity in the secondary devices used in the authentication process.
