Prove your video is real — cryptographically.
TrustCam signs photos and videos at the moment of capture with a key that never leaves your phone's secure hardware. Anyone can then verify who recorded a file, when, and that not a single byte changed since.
How it works
- Capture — the app records photo/video and computes its cryptographic hash on the fly.
- Sign — the hash is signed inside the phone's secure element (StrongBox/TEE). The private key is generated there and cannot be extracted.
- Register — the signed proof (not the file — your media stays yours) is registered with your account and your device's hardware attestation.
- Verify — anyone uploads the file here and sees the owner, device, capture time, and integrity verdict.
What it proves — and what it doesn't
A valid proof means: this exact file was signed by this specific device, registered to this account, at this time, and is unmodified since. It does not prove the scene itself was real: a camera pointed at a screen still signs what its sensor sees. We say what we can prove, nothing more — the technical details are in the paper.
