Design And Implementation Of Mobile Payment System Based On Biometrics Identification

In recent years,with the upgrading of communication technology,the increasingly powerful function of mobile phone and the wide application of 4G technology,the application mode of mobile phone has also been greatly developed.Among them,mobile payment based on mobile phone is an important direction of development.With the increasing application of mobile phone payment,the traditional password and gesture verification can not meet the user's demand for ease of use and security.Biometrics has the advantages of unique,portable,unmemorable and easy to use.The application of Biometric Identification,such as Fingerprint Recognition and Iris Recognition to the security and secure online payments,has become an important development direction for mobile phone research and development.Fingerprint Recognition technology is already very mature,the price of fingerprint sensor is getting lower and lower,and the volume is getting smaller and smaller,so it is used more and more widely.Iris Recognition is a new technology,but it is developing very quickly.The 2 edition of IFAA standard issued by IFAA(Internet Finance Authentication Alliance),established in 2015,supports Fingerprint Recognition and Iris Recognition.It can be authenticated by Fingerprint Recognition and Iris Recognition.This paper introduces the design and implementation of mobile payment system based on Biometrics Identification.It introduces the overall design of the system and the design and implementation of fingerprint module,iris module and payment module respectively.This system adopts layered architecture,which is divided into application layer,application framework layer,hardware abstraction layer,Linux kernel layer and Trustzone layer.The software design of fingerprint module including: fingerprint initialization,set the active wake,fingerprint capture,fingerprint input,fingerprint recognition,fingerprint data storage module.The software design of the iris module includes iris entry and iris verification.The software design of the payment module includes the authentication ID acquisition of the fingerprint payment,the authentication fingerprint list,the payment key writing,the payment key reading and so on.Subject realizes the fingerprint module and iris module Andriod driver development;development process using Andriod multi threading technology to ensure the smooth operation of each module;the use of Trustzone technology to ensure the safety of fingerprint / iris input,unlock the data security of payment security has played a key role;using the SDK2.0 development package introduced by IFAA,the Fingerprint Recognition is applied to the mobile payment.Finally,the system is tested.Through the functional test of each module and the overall performance test of the system,it is proved that the system realizes fingerprint recognition,iris recognition and its application in payment.
