# ProofLens

> ProofLens is a mobile app that verifies whether a photo was captured live from a real, physical object — not reposted, edited, screen-recorded, or AI-generated. Built by Quadible.

## What it does

ProofLens uses a guided live capture process that combines multiple real-world signals from the device to confirm physical presence. It filters out replays, screen recordings, static images, and AI-generated content. Only genuine live captures pass verification.

## Use cases

- Online buying and selling: verify that a seller actually has the item they're listing
- Peer-to-peer marketplaces: prove an item is real before committing to a transaction
- Trust and authenticity: replace "just a photo" with verifiable proof of live possession

## How it works

1. A user (or someone they're transacting with) opens ProofLens and starts a guided capture
2. The app collects real-world signals during the capture to confirm live presence
3. The capture is analyzed and verified — real objects pass, fakes fail
4. A shareable proof link is generated with the verification result

## Platform
