REFILL METHOD
Document Type and Number:
WIPO Patent Application WO/2017/166060
Kind Code:
A1
Abstract:
A refill method, related to the field of data processing, comprising: a terminal receives a third party refill operation of a user and transmits a refill request to a background server on the basis of the third party refill operation (501); the background server verifies the refill request (502), forwards same to a third party system when the verification is successful (503), and, when a refill successful response is received from the third party system, transmits a key acquisition request to a key server (504); the key server receives the key acquisition request and generates a key (505); the key server feeds the key back to the background server (506); the background server generates a request successful response carrying the key and transmits the request successful response to the terminal (507); the terminal extracts the key from the request successful response, performs a card writing operation with respect to a smart card on the basis of the key (508), and transmits to the background server a confirmation request packet carrying a verification code when the card writing operation is successful (509); the background server verifies the verification code in the confirmation request packet and transmits a confirmation successful packet to the terminal when the verification is successful (510); and the terminal receives the confirmation successful packet and records refill successful information (511). The method employs online processing irrespective of refill mode, the refill request and the confirmation request packet are verified by the background server and the card writing is performed by the terminal on the basis of the key issued by the key server, thus solving the problem of poor security with a current refill system, and achieving the effect of ensuring refill security by means of multistep verification in each refill process.
