WebDec 14, 2024 · Apparently, untraceability introduces a trade-off between privacy and authentication (e.g., protection against illicit use). Indeed, untraceability requires hiding the user’s identity, while authentication requires the user’s identity to be known in order to be verified (Samfat et al., 1995 ).
