Verifiable credentials (original) (raw)
Verifiable credentials (VCs) are an open standard for digital credentials. They can represent information found in physical credentials, such as a passport or license, as well as new things that have no physical equivalent, such as ownership of a bank account. They have numerous advantages over physical credentials, most notably that they're digitally signed, which makes them tamper-resistant and instantaneously verifiable. The security of verifiable credentials has been questioned. Verifiable credentials have also been subject to usability concerns. Verifiable credentials can be issued by anyone, about anything, and can be presented to and verified by everyone. The entity that generates the credential is called the Issuer. The credential is then given to the Holder who stores it for later

(en) Verifiable Credentials, in italiano Credenziali Verificabili, sono l'equivalente elettronico delle abituali credenziali fisiche (comunemente detti documenti cartacei) che tutti noi abitualmente possediamo, come ad esempio: carte d'identita', passaporti, diplomi ecc. Il modello dei dati per le Credenziali Verificabili è definito dalla raccomandazione W3C: "Verifiable Credentials Data Model 1.0" pubblicato il 19 novembre 2019. Il modello VC mette il possessore della credenziale (Utente) al centro dell'ecosistema dell'identita', dando all'individuo il pieno controllo dei suoi attributi identificativi (SSI, Self-Sovereign Identity). Questo contrasta con il modello d'identita' federato (Federated Identity Management, FIM), adottato da SAML e OpenID Connect, che mette il fornitore d'identita' (Identity Provider, IdP) al centro come dispensatore di attributi identificativi e determinando a quale Service Provider (SP) fornirli. Nel modello federato la privacy dell'utente e' violata, poiché l'IdP conosce ogni SP che l'utente visita. Il Modello delle Credenziali Verificabili, dall'altra parte, risolve questa centralizzazione dei dati, cercando di ricreare in forma digitale l'attuale modello fisico che tutti noi conosciamo con i documenti cartacei: l'utente detentore dei propri documenti (Holder) li conserva nel proprio portafoglio e può' presentarli ogni volta che qualcuno lo richiede (Verificatore, Verifier), per permetterne la verifica dell'autenticita'. Il tutto avviene senza richiedere il permesso all'autorita' che ha emesso il documento (Issuer). Questo modello e' decentralizzato in quanto chi emette il documento non ha poi il controllo su come questo viene usato e quando dal possessore del documento stesso, delegando a lui (Holder) il controllo sulla propria privacy.
