collection if yyou ask it to. Given the generic nature of some of the phrases
Amazon recognizes—for example, “Will it rain tomorrow?”—it stands to
reason that yyour Echo might be listening more than yyour smart TV is.
Fortunatelyy, Amazon provides wayys to remove yyour voice data from
Echo. 14 If yyou want to delete everyything (for example, if yyou plan to sell
yyour Echo to another partyy), then yyou need to go online to do that. 15
While all these voice-activated devices require a specific phrase to wake
up, it remains unclear what each device is doing during downtime—the
time when no one is commanding it to do anyything. When possible, turn off
the voice activation feature in the configuration settings. You can alwayys
turn it back on again when yyou need it.
Joining the Amazon Echo in the Internet of Things, in addition to yyour TV
and thermostat, is yyour refrigerator.

Google calendar to displayy upcoming events on a flat screen embedded in
the appliance’s door—kind of like that whiteboard yyou once had in its

Google account.
Samsung did several things right in designing this smart fridge. Theyy
included an SSL/https connection so traffic between the refrigerator and the
Google Calendar server is encryypted. And theyy submitted their futuristic
refrigerator for testing at DEF CON 23—one of the most intense hacker
conventions on earth.
But according to securityy researchers Ken Munro and David Lodge, the
individuals who hacked the digital TV communications, Samsung failed to
check the certificate to communicate with Google servers and obtain Gmail
calender information. A certificate would validate that the communications
between the refrigerator and the Google servers are secure. But without it
someone with malicious intent could come along and create his own
certificate, allowing him to eavesdrop on the connection between yyour
refrigerator and Google. 16
So what?
Well, in this case, byy being on yyour home network, someone could not
