How Machine Learning Helps in Financial Fraud Detection?

#artificialintelligence

The financial services sector is undergoing digital transformation, and the driving force behind it is machine learning (ML). ML provides systems with the ability to automatically learn and improve from experience without being explicitly programmed. As the finance sector operates on tons of personal data and billions of critical transactions every second, it becomes especially vulnerable to fraudulent activities. Scammers are always seeking to crack the servers to get valuable data for blackmailing. According to PwC's Global Economic Crime and Fraud Survey 2020, respondents reported losses of a whopping $42 billion over the past 24 months due to fraudulent activities.

Cyber fraud costs organizations billions of dollars each year, and its financial impact continues to climb as criminals are getting smarter and their attacks more complex. While the increasing need for rapid and complex fraud risk detection is common in many sectors, it is perhaps most acute among financial institutions and online merchants. Competition is fierce in these highly digitized markets, and margins are razor-thin. Customers are extremely demanding, and constantly seek better, more user-friendly payment options and channels. Cross-channel fraud detection has been an area of focus for both business and security leaders for nearly a decade.

For years, fraud has been a major issue in sectors like banking, medical, insurance, and many others. Due to the increase in online transactions through different payment options, such as credit/debit cards, PhonePe, Gpay, Paytm, etc., fraudulent activities have also increased. Moreover, fraudsters or criminals have become very skilled in finding escapes so that they can loot more. Since no system is perfect and there is always a loophole them, it has become a challenging task to make a secure system for authentication and preventing customers from fraud. So, Fraud detection algorithms are very useful for preventing frauds.

Fraud is a billion-dollar business and expands rapidly year by year. Thousands of people fall victim to it. Fraud always includes a false statement, misinterpretation, or deceitful conduct. Common varieties of fraud offenses include identity theft, insurance fraud, credit/debit card fraud, and mail fraud. The PwC global economic crime survey of 2018 (PwC, 2018) found that about half of the 7,200 surveyed enterprises had already experienced fraud of some kind. This is an increase compared to the PwC survey conducted in 2016 (PwC, 2016), in which slightly more than a third of organizations surveyed had experienced economic crime.
