# Truth-Check

> Truth-Check is a certified camera app and platform that creates tamper-proof digital evidence. It seals photos, videos, and documents with their metadata (date, GPS location, device model) at the moment of capture, making them cryptographically verifiable and legally admissible.

## Problem Solved

In an era of deepfakes, AI-generated images, and digital manipulation, Truth-Check provides a way to prove that a photo, video, or document is authentic and unaltered. Each certified file receives a unique verification code that anyone can check online — no app or account needed.

## How It Works

1. **Capture**: Take a photo or video directly in the Truth-Check app. No imports allowed — only direct capture guarantees authenticity.
2. **Seal**: A unique cryptographic hash (SHA-256) of the image and its metadata is instantly created and stored immutably.
3. **Certify**: A tamper-proof digital certificate is generated with a unique verification code (e.g., TC-E5A7B2C9D3).
4. **Verify**: Anyone can verify authenticity at www.truth-check.com/{code} — no app, account, or special software required.

- **Construction & real estate**: Certified before/after photos for property inspections, condition reports, and project milestones.
- **Journalism & anti-deepfake**: Prove that a photo or video was captured at a specific place and time. Essential weapon against AI-generated misinformation.
- **Intellectual property**: Establish proof of creation date for designs, inventions, artwork, or prototypes.
- **Education**: Certified diplomas, transcripts, and certificates via the API.
- **Healthcare**: Certified medical imagery for compliance and legal records.
