METHOD FOR UPDATING SEED DATA IN DYNAMIC TOKEN

摘要

A method for updating seed data in a dynamic token comprises: an interaction interface sends user information to an application server for verification, receives a verification result returned by the application server, continuously receives dynamic token information when the verification result is valid, and sends same to the application server; the application server generates a request data packet containing the dynamic token information and application information and sends same to an authentication centre; the authentication centre acquires seed data corresponding to the dynamic token information and the application information and sends same to the application server; the application server converts the seed data into photosensitive data and displays same by means of the interaction interface; and the dynamic token obtains the seed data by acquiring the photosensitive data. The present invention can realize that the seed data in a dynamic token is automatically updated by a user, and meanwhile, a dynamic token can be applied to multiple applications.
