A scientist at Northeastern University is working on technology that he says would be able to detect in real time bombs, guns and other potential threats under clothing and inside backpacks. The project has caught the eye of Homeland Security, which is partially funding the research.
The technology is similar to the electronic devices found at toll collection stop across the nation’s highways. The scientist envisions such a mechanism would be mobile, and could be moved around to sports stadiums, colleges and public spaces.
The technology has drawn the ire of civil liberty advocates, who claim that such surveillance is a breach of an individual’s 4th amendment rights. A prototype is expected in a few years.
