Data and AI are transforming the fight against scams — but only when paired with collaboration. This workshop will spotlight how cross-sector signal sharing is already being deployed in the Asia-Pacific region, featuring case studies from finance, telecommunications, and technology. Speakers will share practical lessons from regional partnerships, demonstrate the value of collaborative platforms such as the Global Signal Exchange, and discuss how these efforts can be scaled to disrupt scams more effectively. Designed as a hands-on session, it will give participants a clear picture of how data and AI can power collective defences.
