Building Security Without the Pervy

Yuri Ivanov of the Mitsubishi Electric Research Laboratories has come up with a comprehensive building monitoring and tracking system that may actually be less invasive of peoples privacy then current CCTV systems. He and his college Christopher Wren outfitted their office with 215 detectors placed at 2 meter intervals. These detectors capture less information in terms of raw data, but they are actually able to generate much more data then a conventional CCTV system. To understand how this is possible one only needs to think of the way that these sensors work.. a motion sensor picks up and relays if and when a person goes by, by having the sensors spaced closely together they are able to track a persons movements through the office. A CCTV on the other hand captures images of the areas they surveil regardless of whether anyone is there or not. Wren explained the difference as such;

"It's not going to catch you picking your nose. You can only tell that some person went by," Wren explains, "maybe this is better than living under thousands of cameras."

The system basically knows that you are in the building but you could be walking around naked and it wouldn't be able to tell. In order to make sense of all the data that these motion sensors capture the pair developed a software package that we have only seen before in Harry Potter of all places, they developed their own version of the marauders map. People on the display show up as bright spots of light with a comet tail that fades away behind them. Giving viewers the ability to both see where they are and what their trajectories are. The program also allows them to compile this movement data over extended periods of time and look for anomalies and patters.

The implications for security and traffic data collection are exciting. The pair was able to analyse data from a fire drill to discover that two out of three of the fire exits went virtually unused. The congregation habits of people and how long they stay at work also have implications for making air conditioning and heating systems more efficient. The system seems like an excellent trade off for better security without compromising personal privacy.
