Problems solved by technology

However, these methods are inseparable from the online payment method of the network. When the network, GPRS, 3G, 4G and other communications are interrupted, the payment cannot be carried out. Therefore, we hope to have a payment method that can realize offline transactions-offline payment , used to solve the problem that the payment cannot be completed when the network communication is interrupted

Abstract

The invention discloses an off-line payment method for bidirectional public key system authenticating of visible light and a bar code. An off-line consumption apparatus with bidirectional authenticating of visible light and a bar code is established and consists of an electronic wallet, a consumption machine and a server. The payment method is implemented by the consumption machine and the electronic wallet. The electronic wallet sends a visible light signal and scans a bar code displayed by the consumption machine during the payment process; the consumption machine receives the visible light signal and generates a display bar code that can be scanned by the electronic wallet. Verification is carried out by using identity information of the consumption machine with a public key password system and the electronic wallet as well as transaction data information of the two sides, so that security of the off-line payment method can be improved and the non-repudiation property of the two sides in transaction can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of optical payment, and in particular relates to an offline payment method authenticated by a visible light and barcode two-way public key system. Background technique [0002] Visible Light Communication (VLC) technology uses high-frequency flickering lights that cannot be perceived by the human eye as an information carrier, uses high-frequency flickering of LEDs to carry signals at the data sending end, and uses high-speed response photosensitive light at the receiving end The component collects the signal, so as to realize the method of wireless communication. [0003] "Scanning code" is a very popular way to obtain information nowadays, usually by using the camera of a smartphone to capture barcodes and identify information from them. [0004] "Scan code payment" is an online payment method developed on the basis of "scan code" technology and WeChat, Alipay and other technologies. The payment method o...
