IFAA fingerprint payment device, system and method, and mobile terminal

Abstract

An embodiment of the invention provides an IFAA fingerprint payment device, system and method, and a mobile terminal. The device includes a TEE module for operating a fingerprint application and an IFAA application under a secure operating system; and an REE module for operating an IFAA client under a general operating system, the IFAA client including a payment application client and or an application client having a payment link established with the payment application client. The IFAA application is configured with a TA bottom interface for access to an RPMB partition of an EMMC and further for connection with the fingerprint application to transmit data between the IFAA application and the fingerprint application. The REE module is configured with an IFAA system framework layer which is connected with the IFAA client. The IFAA application is further configured with a TA inlet connected with the IFAA system framework layer. The TA inlet and the IFAA system framework layer are for data transmission between the IFAA client and the IFAA application. According to the invention, the security and reliability of electronic payment can be well enhanced, the operation is simple and easy, and the user experience is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular, to an IFAA fingerprint payment device, system, method and mobile terminal. Background technique [0002] With the rapid development of network communication technology, electronic payment has become popular rapidly and has become one of people's daily payment methods. People usually install payment clients such as Alipay and bank clients on mobile terminals, and use this payment client Make electronic payments.

AI Technical Summary

Problems solved by technology

However, this password verification method cannot really confirm the user's identity information, because illegal users may also perform payment operations by stealing passwords, etc., and the payment security is poor

At the same time, this password verification method also requires the user to memorize the password or carry a dedicated password generator, which is inconvenient to use

[0004] For the above-mentioned password authentication method in electronic payment, there are problems of poor payment security and inconvenient use, and no effective solution has been proposed so far
