China developed AI-powered security inspection equipment that can speed up body checks
10 May 2018
China has developed AI-powered security inspection equipment that can speed up body checks and alleviate long queues at security in airports. The equipment, developed by China Aerospace Science and Industry Corporation (CASIC), can identify 89 types of contraband in 0.7 sec with an accuracy of more than 95%. Individuals simply walk through the equipment and raise their hands. The device can identify both metallic and non-metallic items. Hazardous and contraband articles underneath a person’s clothes can be detected. In China, most body inspections are conducted with portable scanners, which is labour-intensive and time-consuming. X-ray scanners used in some places cause radiation concerns. The electromagnetic radiation emitted is only one thousandth of that of the mobile phone signal, according to chief designer, Hu Lin. The equipment uses ‘intelligent privacy protection technology’, pixelating people’s faces on image records. Through artificial intelligence, the equipment continuously learns new contraband products. According to Sun Hao from CASIC, the equipment is in full trial service in places such as Beijing Capital International Airport (PEK).
