How Google Home's 'always on' will affect privacy

Google this week took the wraps off Google Home, its smart speaker and home entertainment hub, but questions remain about the impact the device will have on users' privacy. A direct rival to Amazon Echo, Google Home is the company's entry into the smart home market. Want Google Home to play your favorite song? Just say, "OK, Google" and ask for it to play the music. Want the device, which is equipped with its artificial-intelligence based Assistant, to play that funny cat video from YouTube on your TV? Google Home is always listening for the phrase, "OK, Google" so it can take its instructions.
