System and method for preventing recorded voice access to an information handling system using a contextual engine

Abstract

A system and method to prevent passive voice access to the information handling system using a recorded voice includes a microphone to capture buffered acoustical background sounds in a sliding audio buffer and current passive voice access attempt including current acoustical background sounds. A hardware processor executing computer-readable program code of a context gathering module to capture operating conditions of the information handling system and environmental context where the information handling system is deployed, and provide, as input, the sensed operating conditions of the information handling system and environmental context of a contextual environment identification landscape to a contextual environment ML model to generate a context matching score. A voice contextual comparison module generates a voice background matching score and determines when the voice background matching score and the context matching score meet or exceed a threshold access authorization confidence score to determine if access should be granted to the information handling system.
