Quantum-Resistant Photo Authenticity
HashID cryptographically proves when and where a photo was taken, anchoring that proof to Hedera's public ledger. Every photo is signed on-device with post-quantum algorithms before it ever leaves the phone.
Capture & Sign
Take a photo with the iOS app. It computes a SHA-3-512 hash and signs it with ML-DSA-44 — a quantum-resistant signature algorithm.
Anchor to Hedera
The dual hashes and metadata are packed into a compact binary message and submitted to Hedera Consensus Service — creating an immutable timestamp.
Verify Anywhere
Anyone can look up the transaction on Hedera's public mirror node to confirm a photo's authenticity. Try it now.
