PROBLEM STATEMENT • THE REAL-WORLD B2C VULNERABILITY

The ৳1,000+ Crore Consumer Trust Deficit in Bangladesh

Every single day, students, young professionals, and families lose hard-earned money to predatory F-Commerce advance fee demands, task syndicates, and phishing scams without any proactive defense.

80%+

Informal Transactions

The Peer-to-Peer Blindspot

The majority of second-hand and social commerce transactions in Bangladesh occur over Facebook Messenger and unverified personal bKash/Nagad accounts with zero escrow protection.

            Target: University Youth & First-Time Buyers
          

৳500

Advance Delivery Extortion

The Disposable Page Trap

Rogue Facebook pages offer 70% discounts, collect ৳200–৳500 upfront for "courier delivery charge," block the consumer instantly, and clone a new disposable page the very next morning.

            Impact: High Volume, Low Individual Value (Never Reported)
          

100%

Reactive Regulatory Gap

Zero Pre-Transfer Defense

The Directorate of National Consumer Rights Protection (DNCRP / 16121) handles complaints only after money has been stolen. Citizens had zero software-level defense before sending money.

            Statutory Basis: Consumer Rights Protection Act 2009
          

        Domain: B2C AI Consumer Protection
        Bangladesh Target: 170M Citizens & University Youth

TECHNICAL ARCHITECTURE • MULTI-AGENT VERIFICATION PIPELINE

Calibrated Multi-Agent Intelligence Under the Hood

Architected from first principles: deterministic safety filters, multi-modal vision parsing, in-memory legal RAG, and high-speed LLM inference with zero paid cloud lock-in.

STAGE 01

Multi-Modal OCR

Accepts up to 5 screenshots simultaneously. Client-side canvas compression reduces payloads by 85% before OCR extracts bKash transaction IDs, courier slips, and contact numbers.

STAGE 02

Legal Vector RAG

Grounds incoming deals against statutory corpora: Supreme Court judgments (Evaly Writ Petition 8242/2021) and Consumer Rights Protection Act 2009 (Sections 37, 40, 50) without external database latency.

STAGE 03

Gemini AI + Fallback

Orchestrates Gemini Flash Lite for reasoning. If offline or network-degraded, a 100% deterministic heuristic algorithm executes locally, ensuring the safety shield never goes dark.

STAGE 04

Janata Scam Radar

Synchronizes with a real-time community fraud ledger. Crowdsourced upvoting ("Confirm Scam") maintains an authenticated database tracking over ৳13.5 Crore in documented consumer losses.
