Enter a Hedera transaction ID to retrieve the anchored image hash and any public metadata through a worker-assisted Hedera mirror-node lookup. This portal confirms ledger anchoring and hash matches; it does not independently prove ML-DSA authorship or hardware origin.
Paste the transaction ID returned after submitting a photo.
Public verification is intentionally limited to safer checks while topic permissions and portable proof packaging are being tightened.
This page can currently prove:
1. a record exists on Hedera for the transaction ID you enter 2. the anchored hash matches a file you upload 3. whether public metadata was anchored in the record
This page does not currently prove:
ML-DSA authorship, Secure Enclave origin, genuine-app origin, or private-mode metadata decryption for third parties.
This record uses private mode. The signer's app stores the ML-KEM ciphertext needed to reopen the metadata locally, so the public web portal cannot decrypt it on its own.
Ask the signer for a dedicated proof package if you need shared private-metadata verification.
Upload the original photo to confirm its SHA-3-512 hash matches the anchored proof above. A matching hash confirms file integrity for this record; it does not, by itself, prove signer identity or hardware origin. For best results, use the "Export Original" button in the CRISP Cam app, because photos exported from your camera roll may be re-encoded by iOS and cause an exact hash mismatch.
