Abstract
Examples in this application disclose information sharing methods, media, and systems. One example computer-implemented method includes identifying, in a trusted execution environment (TEE), a transaction for invoking a smart contract, where the transaction is a first transaction initiated by a first institution or a second transaction initiated by a second institution, the first transaction comprise a first user identity of a first user and encrypted data of the first user, and the second transaction comprise a second user identity of a second user, updating accumulative invoking information for the smart contract based on the transaction, determining whether the updated accumulative invoking information satisfies an execution condition for the smart contract, executing the smart contract to obtain a user verification result to verify data of the second user, and sending the user verification result to the second institution.
