Abstract: A privacy system having at least one sensor and a device. The sensor may be operational to generate sensor data in response to a user. The device may be in communication with the sensor, in communication with multiple distributed cloud processing nodes, and operational to decompose the sensor data into multiple data items, transmit the multiple data items to the multiple distributed cloud processing nodes, receive multiple processed items from the multiple distributed cloud processing nodes, and generate output data based on the multiple processed items. Wherein individual ones of the multiple distributed cloud processing nodes are operational to generate a corresponding one of the multiple processed items in response to the corresponding one of the multiple data items, a privacy aspect of the user is indeterminable from individual ones of the multiple data items, and the privacy aspect of the user is determinable from the output data.

Abstract: The present application relates to a system and method for receiving, via a microphone array, an incoming acoustic signal including a desired signal and an undesired signal, performing a first minimum variance distortionless response beamforming operation on the incoming acoustic signal to isolate the desired signal, performing a second minimum variance distortionless response beamforming operation, by the signal processor, on the incoming acoust signal to isolate the undesired signal, filtering the desired signal to generate a filtered desired signal, combining an inverse of the filtered desired signal with the undesired signal to generate a combined undesired signal, filtering the combined undesired signal to generate a filtered combined undesired signal, combining an inverse of the combined undesired signal and the desired signal to generate an output signal, and generating a data signal in response to the output signal for transmission via a wireless network.
