A blockchain-based data processing method and apparatus, a computer device, and a computer-readable storage medium. The method includes: obtaining a data authorization request transmitted by an authorization terminal, the data authorization request including a data authorization certificate associated with an authorizer; performing authorization verification on the authorizer according to the data authorization request to obtain a first verification result; signing the data authorization certificate according to a private key of a first blockchain in a case that the first verification result is a valid result to obtain a first certificate signature, determining the first certificate signature as a to-be-uploaded signature, and performing uploading on the data authorization certificate carrying the to-be-uploaded signature; and transmitting the data authorization certificate to a second blockchain, and providing a query permission to a query terminal in a case that signature verification on the to-be-uploaded signature by the second blockchain succeeds.

A method and system for implementing verification within data transfer are provided. The method includes obtaining a user card identifier and a data transfer password of a selected user card through a data transfer request interface. A data transfer verification request to a data transfer server is initiated, the data transfer verification request being generated according to the user card identifier, the data transfer password and a data transfer user identifier. A current time valid identifier that is returned by the data transfer server is received when the data transfer verification is passed, the current time valid identifier being issued when the data transfer server determines that the current time does not exceed a valid period of card-binding time of the selected user card. A secondary verification interface is skipped according to the current time valid identifier. A data transfer confirmation interface is entered.
