Zero-knowledge Proof

Zero-knowledge proof (ZK or ZKP) is an innovative cryptography technique of proving some given statements are true without disclosing any data that needs to keep private. In every zero-knowledge proof system, one party - the prover - can convince another party - the verifier - that a given statement is true without conveying any sensitive information, for example, the possessing of some secret parameters. The technology has already been adopted as the answer to privacy problems in various digital systems.
In our SSI model, privacy is designed as a built-in feature because users’ privacy is our top priority and is always protected by default. With ZKP technology, we allow anyone to prove who they are without the need to disclose their sensitive information or to selectively share a part of their personal information. This approach will tremendously reduce the risks of identity fraud and identity theft.
