Face payment security method based on security unit and trusted execution environment

Abstract

The invention provides a face payment security method based on a security unit and a trusted execution environment, and the method comprises the steps: obtaining a living body percentage through the calculation of face living body detection data and face image data collected by a face recognition trusted application and a face recognition camera, and the trusted execution environment, and then calling the security unit to obtain a percentage signature result and ciphertext data; and enabling the payment application to judge whether the living body percentage is larger than a preset living body percentage threshold value or not, and if yes, carrying out user identity authentication and remaining transactions in combination with a password keyboard in the rich execution environment. In the scheme, the security unit provides a secure cryptographic algorithm service and a face recognition data protection key, the trusted execution environment ensures secure execution of a face living body detection algorithm, and through direct connection with the face recognition camera, protection of integrity, authentication and confidentiality of data in the face payment process is ensured.

Description

[0001] This application is a divisional application with an application date of August 30, 2019, application number: 2019108129583, and the title of the invention is a face payment security method and platform based on a security unit and a trusted execution environment. technical field [0002] The invention relates to the field of face payment, in particular to a face payment security method based on a security unit and a trusted execution environment. Background technique [0003] With the rapid development and evolution of artificial intelligence technology, face recognition technology has gradually been applied in the field of financial payment, and the emergence of face recognition payment applications has introduced potential security risks to the original payment system. In the absence of targeted security protection, face recognition related algorithms and face image data are vulnerable to external malicious attacks in the common operating system of existing payment ...
