The professional services giant, Deloitte, has added to its supply of business block chains a privacy protection technology to proof of knowledge.
Announced on Tuesday at ZKProof community event In Amsterdam, Deloitte has teamed up with QEDIT, an Israeli zero-knowledge proofing specialist, to help users control how a chain of blocks shares the data on certificates and qualifications that they have. they have acquired.
Deloitte Eduscrypt This platform allows organizations to track, share, and validate credentials using a private, licensed version of Ethereum. But there are cases where it is extremely important to control what is shared and with whom. This could be the case in Europe where the General Data Protection Regulation (GDPR) prohibits information about individuals being shared at will.
One solution is to avoid placing data in a blockchain and replacing it with evidence of that data. This is what zero-proof technology does: one party (the prover) can prove to another party (the verifier) that it knows secret information without disclosing anything to that information.
"You can ask a person to prove his credentials, to reveal it to the right people and to retain full control of who learns what, and to have him in a notary blockchain with all the security that it provides. ", said Jonathan Rouach, co-founder and CEO of QEDIT.
Antonio Senatore, Head of Technology at Blockchain Lab of Deloitte EMEA, said that validating, managing and recording staff qualifications and potential hires can be a very expensive and expensive process for most companies, with fines regulatory requirements for non-compliance.
"The integration of QEDIT's Zero-Knowledge Proof privacy solution ensures businesses can trust the authenticity of qualifications, while maintaining the confidentiality of the underlying data and maintaining regulatory compliance," he said. he declared.
Basic need to know
In addition to complying with the GDPR, Rouach pointed out special cases where ZKP would be useful, as aA person who has changed career may want to choose information that can be shared about him.
"For example, a person will prove that she got a security certification from a computer school, but she also learned statistics about the players. So when they go to apply to a bank, they would like to show that they have security but possess nothing else that they could have acquired during their studies. said Rouach.
The event in Amsterdam, presented as the first European "Zero Knowledge" event, is organized by QEDIT and Deloitte and takes place in the offices of the latter. Personalities like ING Bank and Facebook's Calibres also appear.
The goal is to bring the ZKP community together with industries looking to use technology and set standards.
"ZKPs are evolving rapidly, and companies that want to deploy ZKPs do not have experts who can say which implementations are the most mature and reliable," said Rouach.
