Project Overview
With the rapid increase in digital transactions, online scams, and financial fraud, organizations need robust fraud detection mechanisms to protect individuals and businesses. Machine learning (ML) has become a key tool in detecting fraudulent activities, but different ML algorithms offer varying levels of accuracy, speed, and scalability.
This project by Key 2 Smart Security aims to conduct a comparative study of different machine learning algorithms used in fraud detection. The study will evaluate their efficiency, accuracy, and real-world applicability in preventing scams across industries such as finance, e-commerce, and cybersecurity.
