Abstract: A harmonic radar system for detecting an electronic device includes a signal generator for generating one or more transmit radio frequency (RF) signals, a transmitting antenna for sending the transmit RF signals into an environment, a receiving antenna for receiving signals reflected or re-radiated by the electronic device in the environment in response to the transmit RF signals, and a spectrum analyzer for identifying a harmonic frequency of the transmit RF signals in the filtered signals.

Abstract: A method of providing user data privacy for smart devices in a user's home uses a network of smart home routers to route encrypted data packets from the smart devices instead of sending them directly to a cloud-based service. An onion routing network for protecting the privacy of smart devices uses a plurality of smart home routers and an allowlist of domains accessed by smart devices to decide which data packets are routed through the network.
