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 16):
A privacy preserving sensor apparatus, comprising:\n a microphone; a processor; and memory that stores instructions that, when executed by the processor, cause the processor to perform acts comprising:\n extracting a set of features from a signal output by the microphone, wherein the signal is representative of a spoken utterance of a user, wherein 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 further wherein the set of features are unusable by the voice recognition to recognize a second word when the second word is included in the spoken utterance; and \n discarding the signal immediately responsive to extracting the set of features from the signal, wherein the voice recognition system is prevented from receiving the signal or any features other than those in the set of features, and further wherein the signal is unable to be reconstructed based solely upon the set of features.
