Alexa eyes security

In the not-too-distant future, if you can't find your house keys, you'll know exactly where to look: In the Smithsonian. Thanks to Amazon, keys are on their way to becoming artifacts. Today, all you really need to lock and unlock your front door are vocal chords and a simple word: "Alexa." Amazon Smart Home, the company's home security program, has been around since 2014, but only recently has it started working with voice recognition. "Smart Home is something that's been around for a long time," said Daniel Rausch, vice president of Smart Home at Amazon, "but it turned out that customers had to fish in their pocket to control their home. Pull out the remote control, find the appropriate app, find the right page in the app and click a button just to do something as simple as turning on a light."
