Seal what's yours—before fakes go viral.
Hardlock5 seals campaign images and video with an AI neural mark — invisible in the pixels — and anchors a certificate of origin on Klever Blockchain. Anyone can check a file in seconds — free, no login.
- AI neural watermark
- Free public verification
- Proof anchored on-chain
Certify
Issuers sign media with their key.
AI seal
Neural mark in the file; cert on-chain.
Verify
Anyone uploads and gets an honest verdict.
How it works
Three steps. Cryptographic proof.
Authenticity rests on the on-chain certificate — not pixels alone. The AI mark only carries the IDs needed to look the record up.
- 01
Issuers certify media
Upload campaign images or short video, add metadata, and sign with your issuer key.
- 02
AI seal + anchor
An AI neural watermark embeds a compact cert ID into the pixels. The full record is anchored on Klever Blockchain so it cannot be quietly rewritten.
- 03
Anyone verifies free
Drop the file in the public app. We extract the mark, fetch the on-chain cert, and compare the live fingerprint.
Why Hardlock5
Built for proof — not theater
One product: AI-mark the media, anchor the cert, return an honest verdict with limits disclosed.
AI neural watermark
Deep-learning models embed an invisible seal in the pixels — durable through compression and resizing, without changing how your media looks.
On-chain certificate of origin
Signed and timestamped on Klever Blockchain. No one — not even us — can forge or backdate the public record.
Free public verification
Open to everyone. Journalists, platforms, and voters check any file in seconds — no account.
Honest verdicts
Results show match strength, issuer, and limits. Offline we can only say a watermark is present — not that it is authentic.
Built for campaigns
Own the narrative when AI fakes go viral
In the age of generative AI, campaign media is a prime target for deepfakes and synthetic edits. Hardlock5 lets parties and press teams publish photos and videos anyone can verify — and prove a viral fake was never theirs.

What a verification looks like
Toggle real-world scenarios, then run a live check in the free app — no account required.
Real verification is free
This page explains the product. The app runs the check: upload a file, get a verdict, issuer context, and an on-chain link when available.
- No login for public verification
- Honest limitations on every result
- Issuers sign in only to certify new media

Frequently asked questions
What is media certification?
A verifiable proof of origin: who published a file and when. Certification attests to where media came from — it does not judge whether the depicted content is true.
Is Hardlock5 a deepfake detector?
No. We don't analyze whether a file is AI-generated or fake — we prove that a file is yours. A missing certificate doesn't mean media is fake; a present one means its origin is proven.
How does the AI watermark work?
AI neural networks embed an identifier directly into the pixels without changing how the media looks. It withstands common transformations such as compression and resizing. We use AI to seal and extract the mark — not to judge whether content is true.
Do you use artificial intelligence?
Yes. Hardlock5 uses AI neural watermarking to seal images and video at the pixel level. Authenticity still rests on the on-chain certificate: AI carries the lookup IDs; Klever Blockchain holds the signed, timestamped proof. We are not a deepfake classifier.
Which blockchain do you use?
Klever Blockchain, a public blockchain. The certificate is a public, timestamped record — your media itself is never published on the blockchain.
What happens if my media is edited?
Light edits (compression, resizing) normally preserve the watermark. Heavy edits can destroy it — in that case verification reports that origin could not be confirmed. Verification also compares a perceptual fingerprint to tell faithful copies from altered versions.
Is verification really free?
Yes. The public verification page is open to anyone, with no account and no cost.
Can a certificate be revoked?
Yes. The issuer can revoke a certificate at any time — from then on, verifying that media reports the certificate as revoked.
What can't Hardlock5 do?
We don't prove that media content is true, only its origin. Full verification requires blockchain access — offline, we can only indicate that a watermark is present. These limitations are disclosed on every verification result.
