Technical Field
The invention relates to the technical field of coupon deduction, in particular to an off-line electronic coupon deduction method based on a tamper-proof encryption algorithm.
Background
At present, the existing electronic discount coupons in China are mainly divided into three types, namely mobile phone short message searching downloading, internet searching downloading and terminal printing paper, and the short message searching downloading is most convenient. Meanwhile, the electronic coupon is simply and quickly transmitted and used by utilizing a micro-puff technology of a latest information transmission tool and a channel, wherein the micro-puff comprises two main functions of capturing network contents in real time and transmitting the contents to a mobile terminal in real time. Is a novel application mode. The electronic coupon is a special form of the coupon, and a merchant must pay attention to meeting the issuing rule of a general coupon when issuing the electronic coupon. Coupons (or sales promotion tickets) are divided into two categories according to the pricing form. (1) The discount coupon generally refers to that when consumption (or purchase) occurs, a consumer (or a purchaser) can discount and price the discount coupon according to the proportion specified by the discount coupon on the basis of the list price disclosed by a merchant according to the discount coupon. For example, a 2-fold discount is a 20% discount on the price of the listing. (2) The voucher generally refers to a sales promotion document with a certain face value. Such as a one hundred dollar voucher, refers to a voucher that is used during consumption (or purchase) and can be redeemed against 100 dollar cash. Whether electronic or not, coupons are intended to help merchants promote a consumer (or purchaser) in a concessional format for a short period of time. At present, when the electronic coupon is used, a customer directly downloads the electronic coupon from a website of a merchant, the merchant directly carries out discount according to the discount amount of the electronic coupon after watching the electronic coupon, when other people use the tampered fake coupon for use, the merchant does not easily distinguish true from false, so that the benefit of the merchant is influenced, when other people use the coupon for use, the benefit of an impersonated person is also influenced, the safety effect of discount is not good enough, and therefore an offline electronic coupon deduction method based on a tamper-proof encryption algorithm is urgently needed.
