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 for dynamic encryption and signing includes: obtaining, by a terminal during session connection, a predetermined first key index and a randomly-generated first signature index; signing session request data with a first signature corresponding to the first signature index; encrypting the session request data with a first key corresponding to the first key index; sending the encrypted session request data and the first signature index to the server; and receiving, from the server, session response data signed with a second signature corresponding to a second signature index and encrypted with a second key corresponding to a second key index, after decryption and signature verification by the server over the session request data succeed. The second signature index and the second key index are randomly selected by the server and saved in a login session object accessible by both the server and the terminal.

Device, system and method for creating virtual credit are provided. The method includes acquiring user real-name information from a user interface by a terminal device, wherein an electronic exchange account associating with the acquired user real-name information is not saved in a first server; sending the user real-name information to a second server; detecting if a credit card account associating with the user real-name information is saved in the second server, and creating a virtual credit card account if the credit card account is saved in the second server; and storing the virtual credit card associated with the virtual credit card account in the data storage of the first server.

A method for dynamic encryption and signing, a terminal and a server are provided. The method includes that: at least one key and at least one signature are generated through native data; a first predetermined key index and a first random signature index are selected during session connection; a first key and a first signature are located from the at least one key and the at least one signature according to the first key index and the first signature index; session request data is signed with the first signature, and the session request data is encrypted with the first key and sent to a server; and session response data signed with a second random signature and encrypted with a second random key is received from the server after decryption and signature verification by the server over the session request data succeed.

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.

The present disclosure provides a smart card information querying method, including: sending a terminal configuration request to a server, so that the server determines, according to the terminal configuration request, whether a terminal configuration file cached in a terminal needs to be updated, wherein the terminal configuration file is configured based on a geographical area indicated by a smart card and is used for querying smart card information; receiving an update file delivered by the server, when the server determines that the terminal configuration file cached in the terminal needs to be updated; updating the terminal configuration file cached locally according to the update file delivered by the server; and when a connection is established to the smart card in a short-distance communications mode, querying card information of the smart card according to the updated terminal configuration file.
