Smart electricity meters provide power companies with an accurate and streamlined method of monitoring, reading and controlling a home’s power usage. That convenience, however, comes at a steep price and could put homeowners’ safety in jeopardy.
Researchers examining the privacy implications of smart-meter technology found that one German provider’s devices contained vulnerabilities that allowed them to snoop on unencrypted data to determine whether or not the homeowners were home.
After signing up with the German smart-meter firm Discovergy, the researchers detected that the company’s devices transmitted unencrypted data from the home devices back to the company’s servers over an insecure link. The researchers, Dario Carluccio and Stephan Brinkhaus, intercepted the supposedly confidential and sensitive information, and, based on the fingerprint of power usage, were able to tell not only whether or not the homeowners were home, away or even sleeping, but also what movie they were watching on TV.
