Abstract:
A privacy preserving sensor apparatus is described herein. The privacy preserving sensor apparatus includes a microphone that is configured to output a signal that is indicative of audio in an environment. The privacy preserving sensor apparatus further includes feature extraction circuitry integrated in the apparatus with the microphone, the feature extraction circuitry configured to extract features from the signal output by the microphone that are usable to detect occurrence of an event in the environment, wherein the signal output by the microphone is unable to be reconstructed based solely upon the features.

Claim (Index 1):
A privacy preserving sensor apparatus, comprising:\n a microphone that is configured to output a signal that is representative of a spoken utterance of a user; and feature extraction circuitry that is electrically coupled to the microphone, wherein the feature extraction circuitry is configured to extract a set of features from the signal, the set of features are usable by a voice recognition system to recognize a first word when the first word is included in the spoken utterance, and the set of features are not usable by the voice recognition system to recognize a second word that is different from the first word when the second word is included in the spoken utterance, wherein the feature extraction circuitry is configured to discard the signal immediately responsive to extracting the set of features from the signal, and further wherein neither the signal nor any features other than the set of features are provided to the voice recognition system.
