Internet Security through Home Improvement: Anti-wi-fi Paint

By | October 13, 2009

There are many ways in which the home can be made more secure through home improvements, from reinforcing front doors and locks to installing security lights and cameras. However, whilst it is only natural that homeowners protect themselves, their families and their property from burglars and other such criminals, it is often the case that many fail to secure that which is most at risk. Indeed, although it is obviously important to concentrate on the areas of the home that are the most valuable (generally people and property), in this modern age of digital communications it is also necessary to secure the internet.

Of course, it is always important to ensure that firewall, anti-virus and anti-spyware software are installed on all computers and that each is kept up-to-date. Furthermore, computers ought to be password protected at the administrator level and wireless internet must always be encrypted. However, even when these basic steps are followed it is still possible for hackers to break in and do damage. In particular, wireless internet connections have been heavily targeted over the last few years by those who wish to use the web at someone else’s expense, which can be especially damaging when employed for illegal practices. In fact, even an encrypted wireless connection is not entirely safe.

However, online homeowners will no doubt be interested to learn that researchers at the University of Tokyo have developed a so-called anti-wi-fi paint. Comprising aluminium-iron oxide, which resonates at the same frequency as wi-fi, the paint is designed to absorb radio waves and other airborne communications and data. In theory, should the paint make it to the market as expected, it will provide homeowners with the chance to spruce up their walls whilst improving their internet security. Indeed, in theory at least, the paint should block all wi-fi signals from leaving the home.
