2. Introduction
Financial fraud is a compounding worldwide problem with tremendous economic consequences.
Legacy fraud detection is slow and frequently reactive.
Big Data Analytics (BDA) provides robust tools to identify fraud patterns in real time.
The proposal discusses the way BDA enhances fraud detection systems within the finance industry.

3. Problem Statement
Although there have been developments in financial technologies, institutions continue to grapple with:
Late fraud detection.
Restricted use of real-time big data processing.
This study will explore how big data analytics can be utilized to make fraud detection systems more optimal and limit financial crime.

4. Research Objectives
To analyze how big data technology is being applied today in fraud detection.
To discuss important algorithms and models (e.g., machine learning) efficient for anomaly detection.
To assess the effect of BDA adoption on fraud detection accuracy and time.
To suggest a better framework for real-time fraud detection with big data.

5. Research Questions
How does big data analytics increase the efficiency of financial fraud detection?
What are the best data sources for identifying fraud?
What machine learning or AI methodologies are most appropriate for big data-driven fraud detection?
What are some of the challenges in deploying BDA in real-time financial systems?
