As mentioned above, it is sometimes desirable to prevent users from sharing their credentials. In general, there are two well-known approaches. One approach tries to make the credential more protection deserving for the prover by embedding additional valuable secrets into the system. The aim is to make it unpleasant for the prover to share the credential by connecting it with other systems. The other approach is of more technical nature and tries to prevent the prover from sharing credentials by embedding biometric access control. Of course, it should be guaranteed that this access control does not break the user’s anonymity.
