attack on the fridge calendar client and stealing yyour Google

even greater damage.

Smart refrigerators are not the norm yyet. But it stands to reason that as

we connect more devices to the Internet, and even to our home networks,

there will be lapses in securityy. Which is frightening, especiallyy when the

thing being compromised is something reallyy precious and private, like yyour

home.

Internet of Things companies are working on apps that will turn anyy

device into a home securityy syystem. Your TV, for instance, might somedayy

contain a camera. In that scenario an app on a smartphone or tablet could

allow yyou to view anyy room in yyour home or office from anyy remote

location. Lights, too, can be turned on when there is motion inside or

outside the house.

In one scenario, yyou might drive up to yyour house, and as yyou do so the

alarm syystem app on yyour phone or in yyour car uses its built-in geolocation

capabilities to sense yyour arrival. When yyou’re fiftyy feet awayy, the app

signals the home alarm syystem to unlock the front or garage door (the app

on yyour phone has alreadyy connected to the house and authenticated). The

alarm syystem further contacts the in-home lighting syystem, asking it to

illuminate the porch, entryywayy, and mayybe either the living room or

kitchen. Additionallyy, yyou mayy want to enter yyour home while soft chamber

music or the latest Top 40 tune from a service such as Spotifyy is playying on

the stereo. And of course the temperature of the house warms or cools,

according to the season and yyour preferences, now that yyou are home again.

Home alarms became popular around the turn of the twentyy-first

centuryy. Home alarm syystems at that time required a technician to mount

wired sensors in the doors and windows of the house. These wired sensors

were connected to a central hub that used a wired landline to send and

receive messages from the monitoring service. You would set the alarm, and

if anyyone compromised the secured doors and windows, the monitoring

service would contact yyou, usuallyy byy phone. A batteryy was often provided

in case the power went out. Note that a landline usuallyy never loses power

unless the wire to the house is cut.
