Online electronic coupon repeated deduction prevention method based on tamper-proof encryption algorithm

Abstract

The invention discloses an online electronic coupon repeated deduction prevention method based on a tamper-proof encryption algorithm, and the method comprises the following steps: a verification terminal carrying out the authentication of electronic coupon information; if the electronic coupon information is successfully authenticated, the verification terminal sending a use confirmation requestto the server and the mobile terminal; the server receiving the use confirmation information of the verification terminal; and if the electronic coupon information is successfully authenticated and the verification terminal sends a request to the server, bidirectional communication cannot be realized in case of a network fault, at the moment, operating the modification terminal, the modification terminal being wirelessly connected with the mobile terminal, and the modification terminal modifying the two-dimensional code information of the electronic coupon, so that the electronic coupon is prevented from being repeatedly deducted and used. The method is ingenious in design, reasonable in method, capable of effectively avoiding repeated deduction of the electronic coupons, capable of deduction of the electronic coupons under the condition that no network exists temporarily, capable of bringing great convenience to daily use of the electronic coupons for people and suitable for application and popularization.
