Telecom and network scam is one of the most critical social issues today. On a daily basis, over 80 million scam calls are made globally, resulting in financial losses amounting to billions of dollars.
In Hong Kong, the number of
scam cases has significantly increased over the past few years, rising from approximately 15,000 cases in 2020
to nearly 40,000 cases in 2023. Correspondingly, financial losses have escalated from 3 billion to
9 billion HKD.
To tackle this global challenge, COM collaborates with China Unicom and other enterprises, government bodies, and research institutions through technological innovation and international cooperation. The award-winning project focuses on leveraging
big data and AI to build a comprehensive database on global scam cases, integrating multi-source data from police reports, media coverage, and social media. By employing large language models, the project performs an in-depth analysis of the characteristics of both scam perpetrators and victims to provide a detailed understanding of these cases. Furthermore, the model incorporates theories from
communication and psychology to examine the rhetorical strategies and behavioural patterns of scammers. The project also
created customized educational materials to inform the public through diverse channels.
Since the project’s inception, China Unicom has disseminated a total of 1.5 billion public welfare text messages, conducted nearly 4,000 anti-scam awareness activities, and issued 30 million targeted warnings, significantly enhancing public awareness and prevention capabilities regarding scams.
This award has attracted significant media coverage.
Prominent state media outlets such as People’s Daily,
Xinhua News Agency, and
Guangming Online have published comprehensive reports and analyses on the awarded cases. These publications underscore the project's innovation and practicality, while also highlighting its significant social impact.
