AI and ML will detect fraud in banking
Previously, we looked at the diversity of AI applications in banking and financial institutions as well as what kinds of obstacles banks will face when adopting Artificial Intelligence. For now, let’s dive into the role of AI in fraud detection and compliance for banks - a topic of interest to many CEOs and CIOs!
Join our Worldwide AI Webinar - Meet AI experts from global tech giants!

What are fraud activities in banks?

A common type of banking fraud is customer account takeover. This is when someone illegally gains access to a victim's bank account using bots. Other examples of fraud in banking include the use of malicious applications, the use of false identities, money laundering, credit card fraud, and mobile fraud.
Insurance fraud includes premium diversion fraud, which is the embezzlement of insurance premiums, or free churning, which is excessive trading by a stockbroker to maximize commissions. Other forms of insurance fraud include asset diversion, workers' compensation fraud, car accident fraud, stolen or damaged car fraud, and house fire fraud. The motive behind all insurance fraud is financial profits.

Let’s break down the most common types of bank account fraud in order of frequency.

Bank Account Takeover

Bank account takeover, or ATO as it is known, makes up 42% of all bank fraud according to the aforementioned Financial Crime Report. It happens when someone accesses a bank account without authorization. 
Consumers may refer to ATOs as account hacking, but the end results are the same: Someone gains access to the account and mines it for personal information, transfers money to their own account, or gradually drains it of its funds. 
Because bank transfers aren’t reversible, unlike card payments, it is extremely challenging to fix the damages caused by ATO fraudsters. 
As with all kinds of ATO attacks, bank account ATO happens due to:
Note that all of the above can be combined to improve the chances of success. Since many banks now add 2FA checks, fraudsters will also rely on SIM jacking to take control of someone’s phone number and receive passwords via SMS.

What is fraud detection?

Fraud detection is a set of activities undertaken to prevent money or property from being obtained through false pretenses.
Fraud detection is applied to many industries such as banking or insurance. In banking, fraud may include forging checks or using stolen credit cards. Other forms of fraud may involve exaggerating losses or causing an accident with the sole intent of the payout.
Fraud detection has been done by rules-based calculations which are regularly convoluted and not generally extremely difficult to evade. These strategies risk missing a lot of fraud activities or proceeding to have exorbitant measures of bogus up-sides, where client’s cards get declined because of misidentified and dubious ways of behaving. Customary models are likewise entirely unyielding which is an issue in an application where fraudulent are continually tracking down better approaches to sneak by the radar.

How AI aids in fraud detection

In fraud detection, machine learning is a collection of artificial intelligence (AI) algorithms trained with banks’ historical data to suggest risk rules. Bank can then implement the rules to block or allow certain user actions, such as suspicious logins, identity theft, or fraudulent transactions. 
When training the machine learning engine, banks must flag previous cases of fraud and non-fraud to avoid false positives and to improve banks’ risk rules’ precision. The longer the algorithms run, the more accurate the rule suggestions will be.
Techniques for fraud detection and prevention utilizing AI
Fraud data analytics methodologies can be categorized as either statistical data analysis techniques or AI.
Statistical data analysis techniques include:
