A blind signature ensures that the server never learns which message it’s signing. A partially-blind signature protocol allows the server to see a part of the message, but hides another part. For example, a partially-blind signature protocol might allow the server to see the driver’s license data that it’s signing, but not learn the value K that’s being embedded within a specific part of the credential. A second way to accomplish this is for the User to simply commit to K (e.g., compute a hash of K), and store this value within the credential. The ZK statement would then be modified to prove: “I know some value K that opens the commitment stored in my credential.” This is pretty deep in the weeds.
