Method used in a mobile equipment with a trusted execution environment for authenticating a user based on his face

Abstract

A method used in a mobile equipment for authenticating or identifying a user based on his face includes acquiring at least one biometric face sample corresponding to at least one image frame of the user in a Trusted Execution Environment of the mobile equipment, transmitting the biometric face sample to a Rich Execution Environment of the mobile equipment, and classifying at least one portion of the biometric face sample using a classifier in the Rich Execution Environment, so as to generate a set of intermediary outputs and preferably a classification result. The method further includes sending at least some of the intermediary outputs to the Trusted Execution Environment, and verifying at least some of the intermediary outputs in the Trusted Execution Environment.
