<p>The present invention discloses a method for implementing a dynamic code in a cloud payment system, which enables a background server to generate and verify a dynamic code and storing/dynamically loading a verification algorithm for a client and a merchant terminal. Specifically, by means of dynamic loading of an algorithm, a client generates, by means of the algorithm, a dynamic code by performing a security factor integrated processing, and after a merchant terminal collects the dynamic code, the merchant terminal performs inverse operation and verifies the validity of the dynamic code or the client. The dynamic code can be used in multiple applications in payment verification, anti-counterfeiting verification, ATM recognition, vending machine recognition, merchant user/account verification or game account verification. The application of the dynamic code solution of the present invention: based on the implementation of a communications network and a background server or a cloud server, a generation algorithm and a verification algorithm of the dynamic code are separately stored in and dynamically loaded from a remote end, thereby improving the convenience and security of interaction of important information and providing an effective technical solution for interaction of all kinds of practical applications.</p> |
