Those days are gone when finance was limited to manual data entry on spreadsheets. Financial organizations generate more than 2.5 quintillion bytes of information everyday including transactions, assets, investments, and so on. Data Science has revolutionized how companies take smart decisions, detect frauds and manage risks. It is used to process large amounts of financial data and build models that identify the correlation between fraudulent activities and user behavior.

Key Areas Where Data Science in Transforming Finance

  1. Detecting fraud: Algorithms can identify and suspect false transactions faster than any person could do in the past.
  2. Personalized-services: Data science assists to provide certain features of banking based on the transaction habits of the user.
  3. Risk Management: Decrease risks and prevent financial fraud using predictive data science models.
  4. Credit allocation: Banks collect user data on a daily basis such as income, spending, and transactions. After seeing the user behavior, a detailed user profile is created and then data science is used to predict how likely someone will pay back a loan.
  5. Customer Segmentation: Banks target their campaigns more effectively with segmentation. Ever noticed how you suggested your favorite shows on Netflix or how a shopping app knows what you want when you log in? Well, that's customer segmentation. Banks use it to see customer behavior and then based on their history, offer them loans and investment options accordingly.
