Fraud Analytics in Action: Data Science and Machine Learning Techniques for Detecting Fraud in the Digital Age (Palgrave Studies in Accounting and Finance Practice)

 

Fraud Analytics in Action – A Complete Guide to Data Science, Machine Learning, AI, and Financial Fraud Detection in the Digital Age

Introduction

As businesses continue to embrace digital transformation, the volume of online financial transactions has grown exponentially. Digital banking, e-commerce, mobile payments, cryptocurrencies, insurance claims, and online lending have made financial services more accessible than ever before. However, this digital revolution has also created new opportunities for fraudsters, resulting in billions of dollars in losses each year due to identity theft, payment fraud, money laundering, cybercrime, insider threats, and financial scams.

Traditional rule-based fraud detection systems often struggle to keep pace with increasingly sophisticated fraudulent activities. Today, organizations rely on Artificial Intelligence (AI), Machine Learning (ML), Data Science, and Advanced Analytics to identify suspicious patterns, detect anomalies, assess financial risk, and prevent fraud in real time. These intelligent systems continuously learn from historical data, improving their ability to recognize evolving fraud strategies.

Fraud Analytics in Action: Data Science and Machine Learning Techniques for Detecting Fraud in the Digital Age provides a practical roadmap for applying modern analytics to fraud prevention. The book explores how machine learning, statistical analysis, predictive modeling, anomaly detection, network analytics, and AI-driven decision systems can be used to identify fraudulent behavior across banking, insurance, healthcare, taxation, e-commerce, telecommunications, and financial services.

Whether you are a Data Scientist, Machine Learning Engineer, Financial Analyst, Auditor, Risk Manager, Cybersecurity Professional, or AI enthusiast, this book offers valuable insights into one of the fastest-growing applications of data science.
