WaveSign — Invisible File Authentication
Sign and verify images and PDFs with an invisible cryptographic signature. Any modification after signing is detected instantly.
Evaluation Results
| Metric | Result |
|---|---|
| Tamper Detection Rate | 100% on all visible modifications |
| False Rejection Rate | 0% |
| Key Specificity | 100% |
| Signing time | 148 ms mean |

Tested across 900 cases, 22 scenarios. Full results: EVALUATION.md
How It Works
WaveSign uses a proprietary physics-based method to embed an invisible cryptographic signature into your file:
- Secret key → deterministic signing mask
- File content → invisible embedded signature
- Dual-layer verification: content signature + integrity hash
- Any modification — pixel edit, brightness change, crop, compression — invalidates the signature
Your secret key never leaves your device.
Usage
Sign: Upload file → enter secret key → download signed package (.zip)
Verify: Upload signed file → upload .json verification file → enter key → instant result
