A user verification system responding to commands comprises a control unit (11, 21), input means (221) for receiving commands and output means (224, 225) for presenting information to the user. The control unit (21) is adapted to create a harsh value from one or more received commands which is presented to the user by use of the output means (224, 225). The input means (221) is adapted to receive the hash value from the user in, and the control unit is further adapted to verify the identity of the user and associate the identified individual with the received commands based on the received hash value.
