Looking at seven movies and two television shows on five different brands of TV sets, the researchers found that each program had a unique power signature based on how much electric current was needed to show the images on the screen. Among the programs used for the tests was &#8220;Star Trek.&#8221;<br \/>&nbsp;<br \/>&nbsp;Once the programs&#8217; signatures were identified, the researchers found they could then match that information with data coming out of a smart meter. That meant a power company or other entity could mine this data to determine what a household was watching. The test was comprehensive enough to show the technique is broadly applicable and that there is an urgent need for stronger protections for smart-meter data, the researchers said.<br \/>&nbsp;<br \/>&nbsp;As smart meters roll out around the world, the new technology has been met with anxiety and, at times, protests over security and privacy concerns. Last month, a protester was injured during an altercation with a water-utility employee at a demonstration in Ireland, and citizens&#8217; groups in Australia, the U.S. and Canada have mounted campaigns against the installation of smart meters.<\/p><\/blockquote>\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Jordan Robertson: The research, which was published in 2012, measured how much power it takes to display certain programs on a television screen.
