B2C fraud includes insurance fraud, payment fraud, identity theft, etc. and reviewing claims is so time-consuming and difficult that many insurers do little more than a cursory review on small claims. Fraudsters know this and will file—and win—small claims for losses that didn’t really occur.
Machine Learning is fast and efficient (and cheap!) – When it comes to fraud decisions, you need results FAST! ML is like having several teams of analysts running hundreds of thousands of queries and comparing the outcomes to find the best result. But ML models do it all in real-time, in mere milliseconds.
As well as making real-time decisions, ML is assessing individual customer behavior as it happens. It’s constantly analyzing ‘normal’ customer activity, so when it spots an anomaly it can automatically block or flag it for analyst review.
Moreover, ML is more accurate than humans at uncovering non-intuitive patterns or subtle trends before they cause any damage.
For machine learning, as much data as possible should be included. Additionally, the data should be tagged as good (honest customers) and bad (risky customers who have made charge-backs).
Fraud signals can be divided into different categories, such as identity markers (the age of an account, how many devices were used to enter the account), incongruities between billing name and customer name, and more.
Businesses can work with law enforcement to share some information about the clients. Businesses not only look for red flags in terms of conflicts but they also look for connections to organised crime.
Machine learning models need a lot of data in order to work properly—without enough data points, the machine can draw incorrect inferences and flag honest customers or miss fraud cases.
