Login Information Data Processing
Techniques related to login information data processing are described. In one example method, a smart contract is created based on a predetermined smart contract template. The smart contract includes login information corresponding to a user. The created smart contract is stored at a storage address in a blockchain network based on the identifier. A login information query request is received from the user, and the login information query request includes the identifier. At least one smart contract is retrieved from the blockchain network based on the identifier, and the smart contract corresponding to the user is determined from the at least one retrieved smart contract. The smart contract corresponds to the user is executed to obtain at least one login information, and sending the obtained login information to the user.

- 1. A computer-implemented method, comprising:
creating, at an information-processing device, a smart contract based on a predetermined smart contract template, wherein the smart contract comprises login information corresponding to a user, wherein the login information is determined based on a login information storage request sent from the user, and wherein the login information storage request comprises an identifier; storing, the created smart contract at a storage address in a blockchain network based on the identifier; receiving, a login information query request from the user, wherein the login information query request comprises the identifier; retrieving, at least one smart contract from the blockchain network based on the identifier, and determining the smart contract corresponding to the user from the at least one retrieved smart contract; and executing, the smart contract corresponds to the user to obtain at least one login information, and sending the obtained login information to the user.
- 8. A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform operations comprising:
create, at an information-processing device, a smart contract based on a predetermined smart contract template, wherein the smart contract comprises login information corresponding to a user, wherein the login information is determined based on a login information storage request sent from the user, and wherein the login information storage request comprises an identifier; store, the created smart contract at a storage address in a blockchain network based on the identifier; receive, a login information query request from the user, wherein the login information query request comprises the identifier; retrieve, at least one smart contract from the blockchain network based on the identifier, and determining the smart contract corresponding to the user from the at least one retrieved smart contract; and execute, the smart contract corresponds to the user to obtain at least one login information, and sending the obtained login information to the user.
- 15. 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:
creating, at an information-processing device, a smart contract based on a predetermined smart contract template, wherein the smart contract comprises login information corresponding to a user, wherein the login information is determined based on a login information storage request sent from the user, and wherein the login information storage request comprises an identifier;
storing, the created smart contract at a storage address in a blockchain network based on the identifier;
receiving, a login information query request from the user, wherein the login information query request comprises the identifier;
retrieving, at least one smart contract from the blockchain network based on the identifier, and determining the smart contract corresponding to the user from the at least one retrieved smart contract; and
executing, the smart contract corresponds to the user to obtain at least one login information, and sending the obtained login information to the user.
