Princeton researchers: ISP or adversary can use metadata from IoT devices to spy on you via smart devices. Even if youve taken additional steps to protect your privacy, an ISP, or an adversary with capabilities similar to an ISP can still use your smart devices to snoop on you. Researchers found a fix; they used traffic shaping by independent link padding (ILP) to prevent successful smart home privacy attacks. ILP, which involves shaping traffic rates, prevents the amount of small amount of cover traffic from an ISP or several other adversary, as well as several traffic shaping implementations.”]
