Anti-fraud systems [Explained]

A "Credit Card Fraud Detection Service" (CCFDs) has been added to all online stores that accept credit cards. Its task is to determine the percentage of the probability of fraud. It is considered a named Fraud Score (FS) based on the main factors of legality. For example, if the FS is higher than 2.5, then the manager is advised to hold the order or request a call.​

Factors of fraud:

1. Email Domain-they look like your email provider (if it's a free email provider, for example hotmail.com)​

2. Geographical source-IP The country to which the IP belongs and the country to which you enter the store must be the same.​

3. Anonymous proxy-if the client's IP is blacklisted.​

​

9. Spam-checking the IP address in the spam blacklist​

And this is the formula for counting FS:
FS =2.5 * isFreeEmail + 2.5 * countryDoesntMatch + 5 * highRiskCountry + 10 * min (distance, 5000) / maxEarthArc + 2 * binDoesntMatch + 5 * carderEmail + 2.5 * proxyScore +
spamScore/3 maxEarth = 20037.
