Mobile wallet near-field communication payment method based on image encryption

Abstract

The invention relates to a mobile wallet near-field communication payment method based on image encryption. The method is used in a near-field communication payment system which is composed of an NFC mobile wallet, an NFC money collection terminal, a certifying mechanism, a bank account management platform and a third-party payment platform; the NFC mobile wallet and the NFC money collection terminal respectively send real identity identification numbers to the certifying mechanism, the certifying mechanism generates a shared secret key set in communication with the NFC mobile wallet and the NFC money collection terminal and an anonymous identity number set of the NFC mobile wallet and the NFC money collection terminal, the certifying mechanism stores authentication request time sent by the NFC mobile wallet and takes the authentication request sending time, and the shared secret key and shared secret key generating time as encryption information of payment transaction of the NFC mobile wallet; the NFC money collection terminal sends the encryption information sent by the NFC mobile wallet to the certifying mechanism to be authenticated, and safety of the payment transaction of the NFC money collection terminal and the NFC mobile wallet is guaranteed; and a payment password input by the NFC mobile wallet is encrypted through being embedded into an image, and safety of near-field communication payment is further enhanced.

Description

technical field [0001] The invention relates to the field of near-field communication payment, in particular to an image encryption-based mobile wallet near-field communication payment method. Background technique [0002] Near Field Communication (NFC for short) is a short-range high-frequency radio technology, which is evolved from the fusion of non-contact radio frequency identification technology and point-to-point communication technology. It works at a frequency of 13.56MHz within a distance of 0 to 20cm , There are three kinds of transmission speeds: 106Kbit / sec, 212Kbit / sec or 424Kbit / sec, and can switch automatically between different transmission speeds. [0003] NFC has three usage modes: card mode, peer-to-peer communication mode, and card reader / writer mode. Among them, the point-to-point communication mode is used to realize data interaction between different NFC terminals, so as to connect multiple devices with NFC function through communication, and realize ...
