Deloitte Adds Privacy Tech to Its Education-Credentials Blockchain

Professional services giant Deloitte has added zero-knowledge proof privacy tech to its enterprise blockchain offering. Announced Tuesday at the ZKProof Community Event in Amsterdam, Deloitte has teamed up with Israeli zero-knowledge proof experts QEDIT, to help users control how a blockchain shares data about the certificates and qualifications they have earned. Deloitte’s Eduscrypt platform allows organizations to track, share and validate qualifications, using a private, permissioned version of ethereum. But there are instances where it is critically important to have control over what is shared, and with whom. This could be the case in Europe where the General Data Protection Regulation (GDPR) forbids information about individuals being shared willy-nilly.
One way around this is by avoiding putting data on a blockchain at all and instead replacing it with proofs about that data. This is what zero-knowledge proof technology does: one party (the prover) can prove to another party (the verifier) that they know some secret information, without conveying anything at all about the information. “You can have a person prove their credentials and reveal them to the right people and fully retain control of who gets to learn what, and still have that in a notarised blockchain with all the security that it provides,” said Jonathan Rouach, co-founder and CEO at QEDIT.
