PackProof

**PackProof — Don't Just Scan It. Prove It. Anytime, Anywhere.** Counterfeit medicines, drinks, food and everyday products are a serious problem in Nigeria and beyond. A product can have convincing packaging, a working barcode and a matching online registration record—and still leave a buyer uncertain about the physical item in their hands. PackProof is an AI-powered product investigation and evidence-verification network designed to follow products from manufacturers through distributors, retailers and final consumers. Instead of relying on a barcode alone, PackProof connects product identities, packaging, authorized sellers, signed ownership transfers, inspection evidence, applicable notices and custody history into one verifiable record. **How it works:** **1. Investigate:** A buyer enters a product identifier. Our Meta Muse Spark-powered Investigator uses specialized tools to retrieve manufacturer records, product-packaging relationships, seller authorization, notices and custody history. An independent verification engine checks the evidence and determines which claims are supported, blocked or require further investigation. **2. Inspect:** Using an ordinary smartphone camera, buyers capture physical product evidence. Meta SAM 3.1 identifies relevant regions such as packaging labels, allowing the Investigator to examine visible markings. If an expiry date is unreadable or the evidence is insufficient, the agent requests another photograph instead of guessing. **3. Transfer with ChainProof:** Buyers and sellers complete a two-way cryptographically signed QR exchange. PackProof verifies the participants, device signatures, authorization, ownership version and consent before recording the transfer. Each handover contributes to an auditable product history. **4. Verify offline:** OfflineProof exports signed evidence packs that can be transferred between phones and independently checked without internet connectivity. Invalid signatures, expired trust and tampered evidence are rejected. The working prototype includes live Meta-powered investigations, physical inspection, seller authorization checks, two-device signed handovers and real offline evidence verification. Our broader architecture extends this foundation with DualProof dispatch-versus-receipt image comparison, developer APIs, MCP/WebMCP, telephone and radio access, and a compact offline AI assistant for Android/POS devices. PackProof is not another barcode scanner. It is a shared evidence network for humans and AI agents—designed to make product claims independently checkable, even in communities with unreliable connectivity. **Don't just scan it. Prove it. Anytime, anywhere.**
