Sidenotes

Attribute-based digital signatures offer many new possibilities: a police officer, for instance, can sign a report with his/her name and police-registration number; in this way the integrity and authenticity of this report is guaranteed in the whole criminal justice chain. Also, a medical doctor can sign a medical statement with his/her own medical credentials, so that everyone can verify that this statement is actually signed by a medical doctor (and also by whom). Within organisations all kinds of decisions can be registered reliably and verifiably with digital signatures. Yivi is the only identity platform that seamlessly combines both authentication and signing.
