Facial recognition tech convicts man in Chicago robbery case

Handed 22 year sentence after being spotted in surveillance footage


A Chicago man has received a 22-year prison sentence after becoming the first person to be convicted with evidence from the city's facial recognition technology.

Pierre Martin was sentenced Monday for a pair of armed robberies carried out on the Chicago Transit Authority train system. The incidents occurred in January and February of last year, just weeks before Martin would make headlines as the first criminal to be fingered using facial recognition software.

Using a system based on the NEC NeoFace recognition tool, police in Chicago compared surveillance footage from the trains with a database of 4.5 million police mug shots. When Martin's face was identified using a previous mug shot, police were able to make an arrest and later add witness statements.

The arrest was the first to be attributed to the NeoFace system since Chicago police began using the tool in early 2013.

Last month, the 35-year-old Martin was convicted of the February charge, following which he pleaded guilty to the earlier charge, for which he will not have to serve any additional time.

"This case is a great example that these high-tech tools are helping to enhance identification and lead us to defendants that might otherwise evade capture," state attorney Anita Alvarez told the Chicago Sun Times.

NEC pitches its NeoFace platform as a tool for government security and border control agencies. The company says that the suite is able to more reliably compare and analyze faces by breaking images down into smaller segments which are then compared and matched.

While the facial recognition tool won the approval of authorities in this case, activist groups remain wary of facial recognition and other biometric identification tools. Concerned over possible privacy concerns, civil rights groups have sought to closely examine proposed government biometric databases and identification tools for law enforcement. ®

  • World’s smallest remote-controlled robots are smaller than a flea
    So small, you can't feel it crawl

    Video Robot boffins have revealed they've created a half-millimeter wide remote-controlled walking robot that resembles a crab, and hope it will one day perform tasks in tiny crevices.

    In a paper published in the journal Science Robotics , the boffins said they had in mind applications like minimally invasive surgery or manipulation of cells or tissue in biological research.

    With a round tick-like body and 10 protruding legs, the smaller-than-a-flea robot crab can bend, twist, crawl, walk, turn and even jump. The machines can move at an average speed of half their body length per second - a huge challenge at such a small scale, said the boffins.

  • IBM-powered Mayflower robo-ship once again tries to cross Atlantic
    Whaddayaknow? It's made it more than halfway to America

    The autonomous Mayflower ship is making another attempt at a transatlantic journey from the UK to the US, after engineers hauled the vessel to port and fixed a technical glitch. 

    Built by ProMare, a non-profit organization focused on marine research, and IBM, the Mayflower set sail on April 28, beginning its over 3,000-mile voyage across the Atlantic Ocean. But after less than two weeks, the crewless ship broke down and was brought back to port in Horta in the Azores, 850 miles off the coast of Portugal, for engineers to inspect.

    With no humans onboard, the Mayflower Autonomous Ship (MAS) can only rely on its numerous cameras, sensors, equipment controllers, and various bits of hardware running machine-learning algorithms to survive. The computer-vision software helps it navigate through choppy waters and avoid objects that may be in its path.

  • Revealed: The semi-secret list of techs Beijing really really wishes it didn't have to import
    I think we can all agree that China is not alone in wishing it had an alternative to Microsoft Windows

    China has identified "chokepoints" that leave it dependent on foreign countries for key technologies, and the US-based Center for Security and Emerging Technology (CSET) claims to have translated and published key document that name the technologies about which Beijing is most worried.

    CSET considered 35 articles published in Science and Technology Daily from April until July 2018. Each story detailed a different “chokepoint” or tech import dependency that China faces. The pieces are complete with insights from Chinese academics, industry insiders and other experts.

    CSET said the items, which offer a rare admission of economic and technological vulnerability , have hitherto “largely unnoticed in the non-Chinese speaking world.”
