Trust that holds up under audit.
“Verified” is easy to say. Here is exactly what it means at HUMXN: nine layers of checks, records and signatures that travel with every item we deliver.
A record, not a badge.
The proof is built as each item moves through intake, review and delivery, and it can be checked independently.
Illustrative record. Every delivered item carries one.
01Identity
At intake every file gets an exact SHA-256 hash and perceptual fingerprints (crop-tolerant hashes for images, acoustic fingerprints for audio, frame hashes for video, text and shape fingerprints for documents and 3D), so copies are recognized even after editing or re-encoding.
02Uniqueness
Each upload is matched against everything already registered. A file matching someone else's earlier registration is flagged, both parties are told, and it stays out of any dataset until a reviewer resolves it.
03Human origin
Each work records how it was made: human-created, AI-assisted or AI-generated. Generator signatures in EXIF/XMP, IPTC digital-source-type fields and C2PA generation records are detected and override a human-created declaration.
04Consent & rights
The AI-training permission, licence terms and any model or property releases are bound to the work itself. Works showing people are only offered for training when consent is on file.
05Safety & privacy
Uploads are screened against hash block-lists and a safety classifier, and documents and tables are scanned for personal data, which is masked before delivery.
06Expert review
Labels written or checked by experts are marked as expert-reviewed, separately from creator statements and AI suggestions, so you always know who said what about an item.
07Signed provenance
Every work has an Ed25519-signed provenance record and a hash-chained, signed audit trail of every change. Where the format allows, a C2PA manifest is embedded in the file itself.
08Independent timestamp
Each original's SHA-256 is anchored in Bitcoin through OpenTimestamps, so when it existed can be proven without trusting us.
09Delivery marks & receipt
Licensed deliveries carry a forensic mark naming the delivery, and every order comes with a signed receipt listing each item by ID and hash.
What you can prove.
When a regulator, litigator or customer asks where your training data came from, this is the difference between an answer and a document.
Every work's AI-training answer is published in its metadata, response headers, robots rules and TDM reservation.
Records are signed with the registry key, so tampering is detectable.
Timestamps are anchored in a public blockchain, independent of us.
Registration is evidence, not a legal ruling, and we say so.
Data you can defend.
Tell us what your model needs. Every item we deliver comes with the proof above.
