Reality Check
on Photos &
Videos
Stop deepfakes and scams. CleenVerify uses hardware-backed cryptography to digitally sign photos and videos the moment a user captures them, proving they are real.
How It Works
Cryptography-backed trust in 3 steps or less.
1. Capture
Take a photo or video using the Cleen App. We sign it instantly with your device's unique hardware signature.
2. Sign
After the digital signature is placed on your photo or video, a unique verification link is generated for you to share with others.
3. Share
Paste the link on eBay, Marktplaats, Vinted, and social media to prove your photos — and you — are real.
Ask
Whenever you are suspicious of a deepfake or a scam, ask the user to send you a cleenverified photo or video to make sure they are real. They send you a link, and you check the authenticity of the photos and videos on a web page, No login or app required!
Live Capture Only
CleenVerify only verifies media captured live through the app. Users cannot upload media from other sources. This ensures every verification starts at the moment of capture = no fake photos or videos allowed.
Digital Fingerprint
Media captured with CleenVerify gets a unique digital fingerprint—like signing a photo to prove it's yours and authentic.
Hardware Security
Your phone's hardware creates this fingerprint at the moment you capture. This is "hardware-backed verification"—it's locked to your device and can't be faked.
What "Verified" Means
When someone views your link, we check if the digital fingerprint matches the original. If it does, the media is verified. They know your photo or video is real, and unaltered.
The Internet Has a Truth Problem.
We are flooded with more photos, videos, and posts every day than we can process. A growing portion of it is fabricated — and the real and the fake are becoming impossible to tell apart. AI-generated photos are used to scam buyers on platforms like Marktplaats. Deepfake profiles fool people on dating apps. Manipulative fake content triggers anger and panic on social media — and are spread by design. CleenVerify was built to help you prove the difference.
When you use CleenVerify, you're not just sharing a photo or video — you're making a statement: this is real, I am real, and I can prove it.
Selling online — Prove your listing photos are real. Close deals faster on Marktplaats, eBay and other platforms.
Dating & social — Prove you're a real person, not a bot or a deepfake. Likewise, ask the other person to prove the same.
Content & journalism — Prove your work is human-made in an age of AI-generated everything.
“Sus until Cleen.”
Unverified content is suspicious by default. CleenVerify makes the difference visible.
