Information sharing methods, apparatuses, and devices

A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform operations comprising:

• identifying, in a trusted execution environment (TEE), a transaction for invoking a smart contract, wherein the transaction is a first transaction initiated by a first institution or a second transaction initiated by a second institution, and wherein parameters of the first transaction comprise a first user identity of a first user and encrypted data of the first user, and parameters of the second transaction comprise a second user identity of a second user;
• updating accumulative invoking information for the smart contract based on the transaction, to obtain updated accumulative invoking information;
• setting a first threshold for an amount of user identities received in the updated accumulative invoking information;
• determining that the updated accumulative invoking information satisfies an execution condition for the smart contract in response to determining that the amount of the user identities reaches the first threshold;
• in response to determining that the updated accumulative invoking information satisfies the execution condition, executing the smart contract to obtain a user verification result, wherein the user verification result is obtained by executing the smart contract to verify data of the second user;
• and
• sending the user verification result to the second institution.

A computer-implemented system, comprising:

• one or more computers;
• and
• one or more computer memory devices interoperably coupled with the one or more computers and having tangible, non-transitory, machine-readable media storing one or more instructions that, when executed by the one or more computers, perform one or more operations comprising:
• identifying, in a trusted execution environment (TEE), a transaction for invoking a smart contract, wherein the transaction is a first transaction initiated by a first institution or a second transaction initiated by a second institution, and wherein parameters of the first transaction comprise a first user identity of a first user and encrypted data of the first user, and parameters of the second transaction comprise a second user identity of a second user;
• updating accumulative invoking information for the smart contract based on the transaction, to obtain updated accumulative invoking information;
• setting a first threshold for an amount of user identities received in the updated accumulative invoking information;
• determining that the updated accumulative invoking information satisfies an execution condition for the smart contract in response to determining that the amount of the user identities reaches the first threshold;
• in response to determining that the updated accumulative invoking information satisfies the execution condition, executing the smart contract to obtain a user verification result, wherein the user verification result is obtained by executing the smart contract to verify data of the second user;
• and
• sending the user verification result to the second institution.
