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

Abstract

The invention provides a face payment security method and platform based on a security unit and a trusted execution environment. Human face living body detection data and human face image data are collected through a human face recognition trusted application and a human face recognition camera; after the trusted execution environment calculates and obtains the living body percentage, the securityunit is called to obtain a percentage signature result and ciphertext data, the payment application judges whether the living body percentage is larger than a preset living body percentage thresholdvalue or not, and if yes, user identity authentication and remaining transaction are conducted in the rich execution environment in combination with the password keyboard. In the scheme, the securityunit provides a secure cryptographic algorithm service and a face recognition data protection key, the trusted execution environment ensures the secure execution of a face living body detection algorithm, and the integrity, authentication and confidentiality protection of each piece of data in the face payment process is ensured through direct connection with the face recognition camera.

Description

technical field [0001] The present invention relates to the field of face payment, in particular to a face payment security method and platform based on a security unit and a trusted execution environment. Background technique [0002] 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 applications, causing users' payment transactions to face severe security threats. Designing a face recognition secure payment application platform can effectively improve the defense capabilities of payment applications, and ensure the security and st...
