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 12):
A method performed at a privacy preserving sensor apparatus, the method comprising:\n generating, by a microphone, a signal that is representative of a spoken utterance of a user; extracting first features from the signal, the first features are usable by a voice recognition system to recognize that the spoken utterance includes the first word, the first features are unusable by the voice recognition system to recognize that the spoken utterance includes a second word that is different from the first word; providing the first features to the voice recognition system responsive to extracting the first features from the signal, wherein the privacy preserving sensor apparatus refrains from providing the voice recognition system with either the signal or second features that are usable by the voice recognition system to recognize that the spoken utterance includes the second word; and discarding the signal immediately responsive to extracting the first features from the signal.
