Quickly find illegal Deepfake video clips….prevent digital sex crimes
A Student team of the Department of Cyber Security has developed an automatic detection system of Deepfake, which has recently emerged as a social problem.
Deepfake videos refer to manipulated videos, or other digital representations produced by sophisticated artificial intelligence, that yield fabricated images and sounds that appear to be real. Such videos are becoming increasingly sophisticated and accessible. Deepfakes, therefore, are raising a set of challenging policy, technology, and legal issues. A growing number of people are suffering from illegal deepfake videos such as pornography, but there has been no specific way to punish people who make those videos.
The team DEEP't, consisting of five students from the department (Mihyun Kang, Yunhee Kim, Hyunjung Baek, Yerin Yoo, Hyunsun Yoo) won the grand prize at the ‘2020 Startup Storytelling Competition’ hosted by the KITA(Korea International Trade Association) on December 14. Twenty teams who dream of becoming future young entrepreneurs participated in the competition, co-hosted by the KTA, Korea Sanhak Foundation, and UNITEF.
The team DEEP't felt that professional security services of deepfake detection were needed as the technology is advanced at a rapid speed. As a result, they have developed the detection system for about a year since November last year. Team members found that 98% of Deepfake videos are videos featuring women’s faces superimposed onto actresses in pornographic videos, which are emerging as a new social issue in the wake of the ‘Nth Room case’(a criminal case involving blackmail, cybersex trafficking, and the spread of sexually exploitative videos via the Telegram app between 2018 and 2020 in South Korea). Hyunsun Yoo, one of the team members, said, "I have learned to become a female engineer at school, and it was meaningful to develop a system that can prevent the crime in which most of the victims are women."
The students' detection system drew attention as it showed twice the detection speed and a higher accuracy than competing models. "Our model has learned the patterns of AI-based attacks on Deepfake video detection systems, which is recently increasing," said Yerin Yoo. The team is planning to develop its current model with biometric authentication and voice-based detection technology. The students have already been recognized at Ewha as they won the grand prize at the ‘SW Startup Competition’ co-hosted by the Ewha Center for Entrepreneurship and Software-Oriented University Project last November. The team has already finished their IR presentation and is now waiting to attract outside investment.
The team members are the first students to take up the major. The Department of Cyber Security is one of the state-of-the-art majors of the College of Engineering, the world's first women's engineering college. The department aims to foster professional security experts in line with the development of ICT applied to all sectors in society. Mihyun Kang, the team member, said, "The biggest advantage of this major is that students can develop practical skills because we learn latest ICT trends such as blockchain, AI, and big data, after finishing basic courses in computer engineering for the first two years." Professor BoHyung Lee of the department said, "We will help students work for renowned global companies in the future."
