FutureWatch: Telephones That Spot Scams
Nagoya University and Fujitsu first announced a research partnership in November 2009 aimed at developing automated technology to identify situations where one party might overtrust the other.
In March of this year, the team announced the successful development of the world's first system capable of analyzing phone conversations and automatically highlighting suspect situations. The system looks for changes in a caller's voice pitch and level, together with keywords often used and repeated in phone scams. Subsequent verification simulation testing undertaken in collaboration with the National Police Agency of Japan and the Bank of Nagoya found the technology to be over 90 percent accurate in detecting situations of overtrust. Now the research team is about to enter field trials of the system. (more)
