| titleOfInvention | Offline payment method and system based on TOTP algorithm |
| abstract | The invention discloses an offline payment method and system based on a TOTP algorithm, and belongs to the technical field of computers. The method comprises the following steps: the client generates a dynamic verification code as a current dynamic verification code according to a payment key stored in the client, a unique device identifier of the device where the client is located and first current time at intervals of preset time, generates an offline payment code according to the current dynamic verification code, a user identifier and a shared key and sends the offline payment code to a first server through a merchant; the first server deduces a user identifier according to the offline payment code and the shared key, acquires a corresponding payment key, a unique device identifier and an account identifier according to the user identifier, verifies whether the offline payment code is correct according to the second current time, the acquired payment key and the unique device identifier, completes payment through a payment platform according to the account identifier if the offline payment code is correct, returns payment success information to the client and the merchant, and ends; otherwise, returning the payment failure information to the client and the merchant, and ending. |
