Abstract
Methods, systems, and computer program products for generating alerts by matching audio signatures from trusted smart devices are provided herein. A computer-implemented method includes converting one or more captured audio signals originating from a given area of a given environment to one or more audio signatures, wherein the one or more audio signatures correspond to one or more pre-defined user actions within the given environment; comparing the one or more audio signatures to one or more audio signatures associated with one or more user devices authorized to access the given area of the given environment; generating, based on said comparing, an alert upon a determination that the audio signatures do not exceed a threshold level of similarity with respect to the audio signatures associated with the one or more user devices authorized to access the given area; and outputting the alert to one or more of the user devices authorized to access the given area of the given environment.
