Abstract

The invention discloses an electronic coupon processing system and an electronic coupon processing method. The electronic coupon processing method includes the steps of encoding and recognizing user information by the audio encoding and decoding technology, digitally signing and encrypting an electronic coupon by a combined public key mechanism and producing and issuing information of the electronic coupon by a preset terminal. Due to the fact that a cheap terminal mike and a mobile phone handset are used for replacing the traditional expensive intelligent card and a card reader, cost of reducing recognition of a user is reduced. Dangers of revealing and distorting data of the electronic coupon are reducing by digital signature and encryption. Network consumption and internet dependence of issuing the electronic coupon are relieved due to the fact that off-line issuing of the electronic coupon is achieved by the preset terminal.
