Composition method of voiceprint authentication mobile phone payment system

Abstract

The invention belongs to a composition method of a voiceprint authentication mobile phone payment system in the image processing field. The composition method comprises the following steps: selecting a commodity which needs to be purchased, selecting a credit card on a mobile phone, automatically carrying out voiceprint authentication, and carrying out mobile phone payment. The composition method is characterized in that a theory of probability scale distance is imported into the system, voiceprint can be directly transformed into codes, and the codes can be directly used as a mobile phone payment password and can be quickly transmitted on the network. In addition, the codes transformed from the voiceprint can be directly used as the mobile phone payment password, an original system does not need to be changed too much on an aspect of system building, and input cost is reduced. In addition, the voiceprint payment codes are stable and also have a function of adaptive learning, and therefore, system performance is constantly improved. Voiceprint payment has a life body identification function, and lawbreakers can be prevented from defrauding payment via a tape. The consistency authentication of the credit card used for payment and a card holder can be realized, and the mobile phone payment system has high safety.

Description

【Technical field】 [0001] The invention belongs to the construction method of a voiceprint authentication mobile phone payment system in the field of image processing. 【Background technique】 [0002] Recently, the third-party payment for online shopping has knocked down the barriers in the financial field for many years, and the formation of a new network-centric financial system is imperative. Here, the core of fierce competition in all aspects of society is mobile payment technology. In China, the technology that was first applied to mobile payment was the publicized universal two-dimensional barcode. (Non-Patent Document 1) [0003] The release of iPhone 6 with NFC (Near Field Communication short-distance wireless communication technology) function has focused people's attention on the mobile electronic payment system of RFID technology. It is widely used in some convenience stores such as buying train tickets, magazines or snacks. A large number of patent documents we...

Problems solved by technology

[0009] The method described in the above-mentioned non-patent document 1 was once stopped by the national authoritative financial institution because the two-dimensional code was unsafe, and the solution for using the two-dimensional code for mobile payment was blocked

[0010] The mobile phone payment system described in the above-mentioned patent document 1 performs code exchange through wireless communication. Since the security problem has not been completely resolved, especially when the mobile phone is lost, the legal holder of the mobile phone will suffer a relatively large loss. Therefore, this This mobile payment method is only suitable for small payments
