An arrangement for secure user authentication includes a computer or
telecommunication terminal with a smartcard and a device. The smartcard
is adapted to securely store biometric information relating to at least
one user and the device is adapted to detect biometric data of users. The
smartcard and the device include a radio interface for communicating
together and a module for exchanging biometric information between each
other. In this way, tampering of the transferred biometric information is
difficult. In order to increase the security, one or more of the
following measures may be used: a secure communication channel between
the device and the smartcard, a direct (preferably short range)
communication channel between the device and the smartcard and encryption
and decryption of biometric information transferred between the device
and the smartcard.
