Abstract: In this work, we study the use of digital credentials in an online digital identity management setting. We focus on the problem of users sharing their digital credentials with one another, a problem called the "transferability" or "lending" problem. Further, we present the detailed mathematics showing how non-transferability can be achieved through biometrics. By tying the physical identity of a user to their digital identity, we are better able to prevent users from sharing their credentials. Additionally, we implement a state of the art biometric key generation algorithm and apply it to voice biometrics. In our results, we found that we are able to generate cryptographic keys significantly stronger than those of previous work.
