Why should we use Data Science in finance?

With the increase in digitization and online transactions, the risks of online fraud have increased rapidly. This is due to customer data leakage as there might be glitches in online transactions. As customer data is an invaluable resource in this digital era, we need to protect it from fraudsters. This is where Machine Learning and Data Science in finance help, preventing customers as well as organizations from financial losses. Let us understand the uses of Data Science in finance with the help of a use case.

Let us suppose that a customer has an account in Citibank. The bank collects customer’s data comprising transactions, loans, debits, credits, online shopping, and many more. The software used by the bank keeps track of each and every activity of the customer’s account.

After collecting the data, it analyzes the transaction history, transaction amounts, the frequency of transactions, and many other factors. Also, the security software used by the bank records the time and location of the transactions through Data Science techniques. The system flags a transaction if any unusual activity is found such as transactions made from two different locations at the same time.

Moreover, the bank evaluates its potential customers by their account balances. If a huge amount is credited or debited from an account, then the system marks the transaction as suspicious and checks for its validation. Further, on the basis of customer data analysis, the bank decides to give loans, offers, and other benefits to the customers. This helps in making cordial relations with potential customers. This also enhances its revenue generation.

All this is only possible with the involvement of Data Science in the finance industry. Now, we will go through some of the applications of Data Science in the finance industry.
