Abstract
Some embodiments are directed to a system for selectively disclosing attributes and data entries of a record. An issuer device generates a digital signature on a message comprising the attributes and a secret record identifier, and digital signatures on messages comprising respective data entries and each comprising the secret record identifier. The record, secret record identifier, and signatures are provided to a selector device. The selector device selectively discloses attributes and data entries of the record to a receiver device, proving authenticity by means of a zero-knowledge proof of knowledge of the signature on the attributes and signatures on respective data entries. The receiver device verifies the proof with respect to the public key of the issuer and the received attributes and data entries.
