 ## 🎯 Overview
 
-Project S.A.T.A.R.K is an innovative fraud detection system designed specifically for UIDAI Aadhaar enrolment centers. Unlike traditional global threshold-based systems, Sentinel uses **context-aware machine learning** with district-level normalization to identify fraudulent patterns while accounting for India's demographic diversity.
+**Project S.A.T.A.R.K** (Statistical Anomaly Tracking & Aadhaar Risk Kit) is a revolutionary fraud detection system designed to solve the critical "Accuracy vs. Fairness" trade-off in Aadhaar vigilance.
 
-### The Problem We Solve
+### The Problem
+India's demographic diversity makes global rules ineffective:
+- ❌ **Strict Rules:** Flag legitimate activities in tribal belts (False Positives).
+- ❌ **Lenient Rules:** Miss sophisticated fraud in metropolitan areas (False Negatives).
 
-India's demographic diversity creates a unique challenge:
-- 📊 Activities normal in Mumbai may be suspicious in tribal villages (and vice versa)
-- ⚖️ Global thresholds either miss frauds or create false positives
-- 🎯 Need: Regional baselines that adapt to local patterns
-
-### Our Innovation
-
-**District Normalization**: Each enrolment center is compared to its local district baseline, not a national average.
-
-**Example**: In a tribal district with 40% adult enrolment average, a center with 90% adult ratio gets flagged for deviation—even if absolute numbers are lower than urban centers.
+### Our Innovation: District Normalization
+Instead of using a national average, S.A.T.A.R.K compares each enrolment center against its **local district baseline**.
+- **Example:** In a tribal district where late enrolment is common (Avg: 40%), a center doing 90% is flagged. But in a city where 90% is normal, it is marked safe.

-## 📈 Use Cases
-
-### 1. Ghost Identity Creation
-**Pattern**: Abnormally high adult enrolment ratio  
-**Detection**: High positive ratio_deviation  
-**Example**: District avg 40%, center reports 90% → FLAGGED
-
-### 2. Weekend/Holiday Fraud
-**Pattern**: Activity spikes when centers should be closed  
-**Detection**: High weekend_spike_score  
-**Example**: 5x normal activity on Sunday → FLAGGED
-
-### 3. Data Manipulation
-**Pattern**: Discrepancies between biometric and demographic updates  
-**Detection**: High mismatch_score  
-**Example**: 100 demo updates, 20 bio updates → FLAGGED
