For any firm processing online transactions, ensuring a strong shield against fraud is of top priority. And for platforms hosting fantasy sports and online gaming, ensuring a fair play from all users and real-time fraud detection is a first line of defence. Traditionally, rule based engines formed the crux of anomaly and fraud detection. But maintaining a rule engine and adapting to new patterns of abuse are tedious tasks. We’ll see how Machine learning can help us ensure fair play on the platform using user and system finger printing.
- Challenges at Dream11, India’s largest fantasy sports platform
- Referral and promotional events, user registration and game play.
- User data collection and preparing training data
- Regression and Gradient Boosted Models
- Scaling up for real-time decision making
- Business impact and key takeaways
