Researchers: TV Habits Determinable with Smart Meters
PERSONAL PRIVACY—GERMANYSeptember 22, 2011
A Münster University of Applied Sciences study found that, by analyzing patterns in electricity consumption transmitted by a household smart meter, researchers could figure out what program was playing on a television, reports The H Security. Previously, it was thought that smart meter data could only be used to distinguish between appliances, but because of the frequency of the data transfers--every two seconds--this finer analysis is possible, the report states. According to the research team, the discovery means tighter regulations on this data are needed.
