Fraud detection is indispensable for Yahoo! JAPAN , which operates large-scale e-commerce services. Fraudulent payments and sales, such as payments with stolen credit cards, account takeovers, and violations of terms of use, threaten the whole service user.
To make e-commerce more secure for everyone, Yahoo JAPAN has been developing a proprietary anti-fraud system that deals with the ever-changing fraud tricks.
In this session, Akihiro Daigo will trace the history of this anti-fraud system in Yahoo JAPAN, and introduce a mechanism for real-time fraud detection and flexible extensibility for services and developers who implement anti-fraud measures.
