澳大學生於全球深偽技術比賽奪冠

澳門大學科技學院團隊在“2024 Inclusion·外灘大會”舉辦的全球Deepfake攻防挑戰賽中,與海內外20多個國家和地區的7,000多支隊伍、近萬名選手同台較量,包括麻省理工學院、斯坦福大學、北京大學、新加坡國立大學、微軟、谷歌、字節跳動、中國科學院自動化研究所、微軟亞洲研究院、新加坡科技研究局等,最後奪得冠軍,並獲獎金10萬元人民幣。

深度偽造技術(Deepfake)利用先進的深度學習算法,通過對大量的視頻和圖像數據的學習,便能夠偽造出高度逼真的面部動畫和語音合成效果,即是“AI換臉”技術。這項技術不僅增加了公眾識別視頻真偽的難度,也進一步助長了詐騙、色情等違法犯罪活動的風險。面對日益嚴峻的“AI換臉”詐騙事件,培養具備實戰技能的專業人才至關重要。比賽針對“AI換臉”攻防實戰演練,有助於促進產學研結合,激發人工智慧領域的人才發展,推動研發有效抵禦各類場景下的深偽攻擊,保障行業和社會。

獲得冠軍的隊伍由澳大科技學院學生陳逸鳴、李風朋、李科謀、黃嘉謙、李政、陳翔宇、宋彬彬、徐書凝、劉雋和澳大校友吳海威組成,導師為電腦及資訊科學系主任周建濤。他們的得獎方案不僅引入了數據類型感知的無監督聚類方法,以重新劃分數據集來模擬跨域測試場景,並研發了特徵級對抗訓練算法及類型增廣算法,增強了數據類型並引導檢測模型學習適應多類型、多場景的高泛化深度偽造技術特徵。此技術可協助識別深度偽造技術偽造內容,有效防止因該技術濫用而導致的詐騙行為,保護行業和社會免受由此帶來的負面影響。相關研究成果已共享於社區平台https://github.com/HighwayWu/DeepFakeDefenders

是次比賽由螞蟻科技集團股份有限公司主辦,螞蟻(廣西)數字科技有限公司承辦,中國科學技術大學網絡空間安全學院、中國圖像圖形學學會等作為學術合作與聯合協辦,並通過全球知名的數據科學競賽平台Kaggle進行。

UM students win championship at global deepfake detection competition

A team from the Faculty of Science and Technology (FST) of the University of Macau (UM) won the championship and a prize of RMB100,000 at the Global Multimedia Deepfake Detection Challenge held during the 2024 Inclusion Conference on the Bund, after competing with nearly 10,000 participants from over 7,000 teams from more than 20 countries and regions. These teams came from renowned institutions and companies, including the Massachusetts Institute of Technology, Stanford University, Peking University, the National University of Singapore, Microsoft, Google, ByteDance, the Institute of Automation of the Chinese Academy of Sciences, Microsoft Research Asia, and the Agency for Science, Technology and Research in Singapore.

Deepfake technology utilises advanced deep learning algorithms to create highly realistic facial animations and voice synthesis effects by learning from large amounts of video and image data, also known as ‘AI face-swapping’ technology. This technology not only makes it more difficult for the public to determine the authenticity of videos but also increases the risks of fraud, pornography, and other illegal activities. Given the growing threat of ‘AI face-swapping’ fraud, it is vital to cultivate professionals in this area. The competition focused on practical exercises in ‘AI face-swapping’, which helped foster industry-academia collaboration, talent development in artificial intelligence, and the development of solutions to effectively counter deepfake attacks in various scenarios, thereby safeguarding industries and society.

The winning team consisted of FST students Chen Yiming, Li Fengpeng, Li Kemou, Wong Ka Him, Li Zheng, Chen Xiangyu, Song Binbin, Xu Shuning, and Liu Jun; and UM alumnus Wu Haiwei. They trained for the competition under the guidance of Zhou Jiantao, head of the Department of Computer and Information Science. The team’s winning solution not only introduced a data type-aware unsupervised clustering method to reclassify datasets for simulating cross-domain testing scenarios, but also developed feature-level adversarial training algorithms and type augmentation algorithms. These innovations enhanced data types and guided detection models to learn high-generalisation deepfake features adaptable to multiple types and scenarios. This technology helps identify deepfake content, effectively prevent fraud caused by the misuse of deepfake technology, and protect industries and society from its negative impact.

The competition was organised by Ant Group and presented by Ant Group Digital Technologies, with academic collaboration from institutions including the School of Cyber Science and Technology at the University of Science and Technology of China, and the China Society of Image and Graphics. The competition was hosted on the renowned data science competition platform Kaggle.
