Voice coil motor Arihei technology recognizes fake human faces. Xue Hui, head of Alibaba Security Turing Lab, introduced that Alibaba's “1:1 Face Detection” face verification product uses motion detection and data model deep learning to comprehensively determine risk.

     This technology product has been applied to all Ali system platforms. In the face of complex situations such as irregular user submissions and counterfeiting on the Internet, 98.31% of human faces can be certified through deep learning, and the false detection rate is lower than 100,000. One, and effectively identify PS, three-dimensional face change and other software.

     When the algorithm model encounters a difficult-to-determine certification situation, there will be manual intervention for verification to ensure accuracy. Up to now, the technology's identification ability still maintains a record of "zero mistakes."

     “Using photos and videos posing as images, there are differences in appearance from face to temperature, skin texture, micro-expressions, and micro gestures,” says Xue Hui. Alibaba Certified products can recognize mouth shape and face movement. Matching sensors, face appearance matching lighting, focal length recovery shape, face continuity detection, face video pulse detection technology, etc., produce dummy faces within milliseconds, allowing cheaters to nowhere.

     "It's like walking under a lamp, black and gray production is behind the shadow," Xue Hui said, every day Taobao metropolis nearly 4 million malicious attempts to log in, and the offensive and defensive production of black and gray production seems endless, each time the technology advances, The means of attack will also be updated later.

     “There is no absolute security in the world,” said Zheng Junfang, chief risk officer of Alibaba. In more than ten years, 3000 Ali security people have built a defense line that is much higher than the security level of the same industry, and prevented attacks that are happening all the time, but As the world's largest e-commerce platform, cyber security challenges never stop. "Only by making technology more advanced and making models more intelligent can we continue to provide more reliable services and protect more consumers."
