Abstract
Methods and apparatus are provided for embedding auxiliary information in one-time passcode authentication tokens. Auxiliary information is embedded in authentication information transmitted to a receiver by obtaining the auxiliary information; and mapping the auxiliary information to a codeword using a secret key, wherein the secret key is shared between the security token and an authentication authority; and combining the codeword with a tokencode generated by a security token to generate a one-time passcode. The one-time passcode can then be transmitted to the receiver.
