Verified Product Photos for Online Marketplaces
Eliminate fake product listings with verified photos. SHA-256 hashing proves items exist and match descriptions for eBay, Craigslist, Facebook Marketplace sellers.
Fake Product Photos Are Fueling Marketplace Fraud
Online marketplaces lose billions annually to listing fraud powered by stolen and AI-generated product photos. Scammers download images from legitimate sellers, use AI to generate photorealistic product shots, or repurpose old photos to sell items that don't exist or don't match the description.
For honest sellers, competing against fraudulent listings with professional-looking stolen photos is nearly impossible. Buyers who've been burned by fake listings become skeptical of all sellers, driving down response rates and forcing legitimate merchants to slash prices to overcome trust deficits.
Platform-level verification can't solve this at scale. What's needed is seller-level proof that the product in the photo actually exists, was photographed by the seller, and looks exactly as described — right now, today.
Proof of Physical Possession for Every Listing
Proof.show provides something no marketplace currently offers: cryptographic proof that a seller physically possesses the item they're listing. The live-only capture requirement means the photo must be taken in real-time through Proof.show — no uploading old images, no AI-generated product shots, no stolen photos from other listings.
The SHA-256 hash locks the image at the moment of capture, and the NTP atomic timestamp proves exactly when the product was photographed. Buyers can verify any listing photo instantly with the Proof Code, confirming the item exists and was genuinely photographed by the seller.

How It's Used
Frequently Asked Questions
Proof.show only accepts live camera captures — gallery uploads are blocked entirely. This means sellers must physically photograph the actual item in real-time. AI-generated images, stock photos, and stolen listing images cannot enter the verification pipeline.
Yes. Each verified photo generates an 8-character Proof Code. Include it in your listing and buyers can verify at proof.show/v that the photo is genuine, unedited, and was taken at the timestamp shown. It builds instant trust.
Proof.show is especially valuable for high-value items where fraud risk is highest. The atomic timestamp and SHA-256 hash prove the item was in the seller's possession at a specific time, and the photo hasn't been altered — critical for electronics, luxury goods, and collectibles.
