🏗️ System & ETL Data Pipeline Architecture

TrustScan processes incoming document uploads (PDFs, images), text payloads, and external security feeds through an automated Extract - Transform - Load (ETL) pipeline:

┌────────────────────────────────┐     ┌────────────────────────────────┐     ┌────────────────────────────────┐
│       1. EXTRACT STAGE         │     │      2. TRANSFORM STAGE        │     │         3. LOAD STAGE          │
│ Multi-Source Payload Ingestion │ ──► │ Data Cleaning & Validation     │ ──► │ Dual-Database Storage &        │
│ (PDFs, Images, REST API Signals)│     │ (Python, OpenCV, OCR Rules)    │     │ Asynchronous Worker Pools      │
└────────────────────────────────┘     └────────────────────────────────┘     └────────────────────────────────┘

1. Extract Stage (Ingestion & Image Preprocessing)

• Multi-Format Extraction: Ingests raw HTTP payloads, scanned PDFs, and image streams.
• OpenCV Denoising: Applies image thresholding, grayscale conversion, and contrast alignment to prepare low-quality document scans.
• Hybrid OCR Pipeline: Combines PyMuPDF, Tesseract, and EasyOCR to extract text, bounding boxes, and structural metadata from image-only PDFs and documents.

2. Transform Stage (Data Quality, Validation & Telemetry)

• Mathematical Identity Validation:
  • Aadhaar Checksum: Validates identity numbers using the Verhoeff algorithm.
  • PAN Structural Verification: Validates registration format (Individual vs Company).
  • GSTIN / CIN Verification: Performs mathematical checksum validation against official Indian business registers.
• AI Forensics & Edit Detection: Detects metadata signatures from generative AI tools (Midjourney, DALL-E) and image manipulation tools (Photoshop, Canva).
• Telemetry Feedback Loop: Runs automated data quality routines before database writes, improving scoring accuracy by 40% and reducing false positives by 25%.

3. Load Stage & Latency Optimization (90s → <15s)

• Dual-Database Load Strategy:
  • MongoDB: Stores flexible, unstructured document payloads and OCR extractions.
  • PostgreSQL: Stores relational user data, security logs, and analytical metrics.
• Asynchronous Worker Queue Optimization:
  • Initial Bottleneck: Synchronous processing on the primary web thread took 90 seconds per request.
  • Engineering Solution: Decoupled ingestion from heavy processing by implementing asynchronous background workers and adaptive worker pool scheduling, cutting processing latency down to under 15 seconds (85% reduction).
