RELIABLE FRAUD DETECTION MODELS FOR BFSI

2. INTRODUCTION
DATA ANNOTATION IN THE CONTEXT OF BFSI FRAUD DETECTION
Fraud detection in the BFSI sector depends on the quality of data used to train
AI models. Data annotation helps transform raw financial data into structured
insights — enabling machine learning systems to detect anomalies, identify
fraudulent behavior, and safeguard customer trust.
TYPES OF ANNOTATIONS USED
HOW QUALITY ANNOTATION BUILDS RELIABLE MODELS
Data annotation in BFSI means labeling and categorizing transactional,
behavioral, and document data so fraud detection systems can learn and adapt
accurately.
1️⃣ Transaction Labeling – Marking legitimate vs. suspicious transactions
2️⃣ Entity Annotation – Tagging individuals, accounts, or organizations involved
3️⃣ Behavioral Pattern Annotation – Identifying spending habits and outliers
4️⃣ Document Verification Annotation – Labeling KYC and compliance data
Reduces false positives and negatives
Enables early detection of fraud patterns
Improves compliance accuracy
Enhances trust in automated systems
