SignedShot

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.

Key Features • Cryptographic signing using Apple's Secure Enclave • Device attestation via App Attest • Tamper-evident sidecar files • Open protocol (verify anywhere) • Privacy-first: no cloud uploads required

Open Source SignedShot is built on an open protocol. The code is public, the cryptography is standard, and anyone can verify the results.
