How to make credit card payments safer?
We are building a modular fraud detection system which uses geographical analysis and rule- based predictions based on historical actions.
We are using innovative, open source technology: Scala, Apache kafka (a message broker for rule-based processing of data feeds in real-time) and RS (risk shield) ING wants to go from connected to predictive. Therefore we need to improve their speed from 700 transactions per second to 2000 TPS and make their system more real time. The technology used, allows near real time computation.
Concretely – when entering your credit card, the goal is to know before you retrieve cash if it is a fraudulent transaction or not (and act upon it).
