Embodiment Construction

[0079] The scheme of the present invention to realize the secure electronic transaction system uses the theory of public key cryptography in cryptography to propose an encrypted token card ("ETC card") to complete the cash payment on behalf of the customer, and produce commodities with barcodes ("BCC commodity") to complete the delivery of goods on behalf of the merchant. , Realize the authenticity of the transaction process between customers and merchants. The specific electronic transaction program flow is composed of customer transaction process and merchant transaction process.

[0080] The customer transaction process consists of the ETC card issuance stage, the electronic payment stage and the commodity authentication stage, as follows:

[0081] The first step: ETC card issuance stage

[0082] 1). The customer applies for an ETC card to the card-issuing bank, and the card-issuing bank decides whether to accept the customer's request or not according to whether the custom...

Abstract

The scheme for implementing safety electronic transaction system by utilizing public key cryptosystem adopts the following main measures: customer makes an application for issuing enciphered cash-transposing card (ETC card) to card-issuing bank, and the shop can make an application to logistics commodity issue organization (LCID) for issuing bar code commodity (BCC), so that ETC card can be substituted for cash, and the BCC commodity can be substituted for general commodity. Said invented electronic transaction scheme process is composed of customer's ETC card-issuing stage, electronic payment stage, commodity authentication stage, shop's BCC commodity issuing stage, logistics delivery stage and drawing authentication stage.

Description
