Abstract
Techniques are provided for entering a secret into a security token using an embedded tactile sensing user interface with the purpose of verifying the secret against a stored representation of the same secret. In particular, an embodiment of the security token according to the invention comprises a tactile sensing user interface being arranged to receive a user-encoded secret, a decoding unit being arranged to generate a decoded secret by decoding the user-encoded secret, a comparison unit being arranged to compare the decoded secret with a copy of the secret stored in the token in order to verify the authenticity of a user. Thereby, the security token provides on-card matching functionality.
