Signed at capture. Verified anywhere.
SignedShot creates cryptographic proof that your photos are authentic at the exact moment you take them. No detection algorithms. No guessing. Just verifiable evidence of where your photos came from.
How It Works
1. Take a photo with SignedShot
2. Your device signs the image using the Secure Enclave
3. A cryptographic sidecar is generated with proof of capture
4. Anyone can verify your photo hasn't been altered
Why It Matters
In an era of AI-generated images and deepfakes, proving a photo is real matters more than ever. SignedShot doesn't try to detect fakes; it proves authenticity at the source.
