A Review on Security in Smart Home Development
[attachment=23140]
Introduction
Smart homes connect all the devices and appliances in your home so they can
communicate with each other and with you. Anything in your home that uses electricity can
be put on the home network and at your command. Whether you give that command by voice,
remote control or computer, the home reacts. Most applications relate to lighting, home
security, home theater and entertainment and thermostat regulation. Security has been an
important issue in the smart home applications. Conventional security systems keep
homeowners, and their property, safe from intruders. A smart home security system, however,
offers many more benefits. On the following chapters, we discuss smart home, smart home
security and related tools in smart home security.
Smart Home Systems
A smart home or building is a home or building, usually a new one that is equipped with
special structured wiring to enable occupants to remotely control or program an array of
automated home electronic devices by entering a single command. For example, a
homeowner on vacation can use a Touchtone phone to arm a home security system, control
temperature gauges, switch appliances on or off, control lighting, program a home theater or
entertainment system, and perform many other tasks. [1]
The field of home automation is expanding rapidly as electronic technologies converge.
The home network encompasses communications, entertainment, security, convenience, and
information systems. [1]
A technology known as Powerline Carrier Systems (PCS) is used to send coded signals
along a home's existing electric wiring to programmable switches, or outlets. These signals
convey commands that correspond to "addresses" or locations of specific devices, and that
control how and when those devices operate.
Smart Home Software and Technology
Smart home technology was developed in 1975, when a company in Scotland developed
X10. X10 allows compatible products to talk to each other over the already existing electrical
wires of a home. All the appliances and devices are receivers, and the means of controlling
the system, such as remote controls or keypads, are transmitters. If you want to turn off a
lamp in another room, the transmitter will issue a message in numerical code that includes the
following:
An alert to the system that it's issuing a command,
An identifying unit number for the device that should receive the command and
A code that contains the actual command, such as "turn off."
Setting Up a Smart Home
X10, Insteon, ZigBee and Z-Wave just provide the technology for smart home
communication. Manufacturers have made alliances with these systems to create the products
that use the technology. Here are some examples of smart home products and their functions.
Cameras will track your home's exterior even if it's pitch-black outside.
Plug your tabletop lamp into a dimmer instead of the wall socket, and you can
brighten and dim at the push of a button.
A video door phone provides more than a doorbell -- you get a picture of who's at the
door.
Motion sensors will send an alert when there's motion around your house, and they
can even tell the difference between pets and burglars.
Door handles can open with scanned fingerprints or a four-digit code, eliminating the
need to fumble for house keys.
Audio systems distribute the music from your stereo to any room with connected
speakers.
