Abstract: A Zero Knowledge Proof (ZKP)-based privacy protection method and system for authenticated data in a smart contract wherein initialization is performed. Inputting a security parameter obtains a public parameter. A Data Authenticator (DA) generates a public/private key pair. A key pair is generated using the public parameter and a verification circuit as inputs, the key pair including a proof and a verification key. Authentication on private data of a Decentralized App (DApp) User (DU) is performed using the private key of the DA, and generates a signature. A DU prover terminal inputs private data as an input value and a calculation result and hash value as output values. The DU generates a ZKP using the proof key. A validator verifies whether the ZKP is correct. If verification passes, the calculation result is correct; otherwise the calculation result is wrong. The validator executes a smart contract based on the verification result.
