Photo and video authenticity infrastructure

Photos and videos you can actually trust

From listings to inspections to proof a job was done, Danaya seals every photo and video with verifiable proof at the moment of capture. Send a capture link to anyone, or plug it into your platform via API.

How the proof holds up

Anatomy of a seal

Every photo and video captured through Danaya is sealed with four cryptographic elements. Together they make the proof impossible to fake or alter after the fact.

SHA-256 hash

A unique fingerprint of every pixel and frame. Change one pixel and the hash no longer matches.

a1b2c3d4…e7f8

GPS location

The real coordinates, locked at the exact moment of capture. Not editable afterwards.

48.8566°N, 2.3522°E

Timestamp

The exact moment of capture, certified to the second. No backdating possible.

HMAC signature

A server signature over all of the above. It seals the seal itself, so nothing can be tampered with.

verified ✓

One seal · four elements · verifiable by anyone

A photo or video can only be sealed once, at the moment of capture. Re-saving or screenshotting breaks the seal, so only the original is authentic.

Live capture only

No file upload. Photos and videos are captured live, never imported.

You control storage

Keep the original media or don't. Storage is optional, your choice per seal.

Verifiable by QR

Anyone can check a seal by scanning a code. No account, no install.

Works in any browser

Capture from the phone browser. Nothing to download.

No code needed

Send a link. Get proof back.

Your agents, clients or field teams capture sealed photos and videos straight from their phone browser. No app to install, no account to create, no code to write.

On your side

Generate a capture link

From your dashboard, create a link tied to a case. Send it by SMS, WhatsApp or email.

They open the link, the camera opens, they capture. The seal lands in your dashboard, under the right case.

RECno account · no install · browser only

The person capturing never needs an account. You keep every proof, centralized.

Built for the work that needs proof

Listings & rentals

rental platforms · classifieds · real estate

Every listing carries photos proven real at the moment of capture. Stolen, recycled or AI generated images can't earn a valid seal, so they can't pass for the real thing.

Inspections

property management · agencies · surveyors

Document move-in and move-out condition with photos and videos that hold up in any deposit dispute.

Proof of work

field services · installers · contractors

Field teams prove a job was done, exactly where and when it was done, straight from their phone.

Marketplaces

resale · secondhand · peer to peer

Sellers photograph the real item, live. Buyers verify a photo is genuine before they pay, so what you order is what you get.

Public verification

Check a seal in one step

Open the verification link, drop in the photo or video, and Danaya tells you if it matches the seal. No account, no install, nothing to trust but the cryptography.

Step 1 · Verification link

Seal fbwx-p9cm is already loaded from the link. Nothing to type.

Step 2 · Upload the media to check

If the file had been edited, even by one pixel, the hash would not match and the result would read Not authentic.

Hash comparison

Danaya recomputes the file's hash and compares it to the seal.

Signature check

The HMAC signature confirms the seal itself was not altered.

Authentic or not, with the sealed location and time.

Free AI analysis

Detecting fakes is a losing race

Danaya can scan any photo, video or audio for signs of AI generation or manipulation, and it gives a confidence score. It's free, one check a day, no account needed. But detection only ever gives you a probability. Real certainty comes from proof at the source.

~78% likely authenticconfidence, not proof

Detection reads patterns and guesses. As generators improve, the guess gets harder, and a determined faker can slip through.

A sealed photo carries proof of when and where it was taken. No guessing, no probability, it either matches the seal or it doesn't.

Detection fights the symptom. Danaya ends it at the source.

Questions people ask about Danaya

What is Danaya?

Danaya is a photo and video authenticity platform. It seals a photo or video with cryptographic proof at the exact moment of capture, so anyone can later verify the media is genuine and unaltered. It also offers a free AI detector that scans a file for signs of AI generation.

How does Danaya prove a photo or video is real?

When you capture through Danaya, it seals the media with four locked elements: a SHA-256 hash of the file, the GPS location, a server timestamp, and an HMAC server signature. If the media changes afterwards, the hash no longer matches and the file reads as not authentic.

What is the difference between AI detection and Danaya's sealing?

Detection analyses a finished file and returns a probability that it is fake, which gets less reliable as AI generators improve. Danaya's sealing works at the source: the media carries proof of when and where it was captured, so verification is a definite cryptographic match, not a guess.

Can Danaya detect an AI-generated or deepfake image?

Yes. Danaya includes a free analyzer that scans any photo, video or audio for signs of AI generation or manipulation and returns a confidence score, with one free check a day and no account needed. For certainty rather than probability, Danaya's cryptographic seal proves authenticity at capture.

Does the person taking the photo need an account or an app?

No. With a Danaya capture link, you send a link by SMS, WhatsApp or email, the person opens it, the camera opens in their browser, and the sealed proof lands in your dashboard. They never install an app or create an account.

Can I upload an existing photo to seal it?

No, and that is the point. Danaya only seals media captured live through the camera, never imported files. This is what stops stolen, recycled or AI-generated images from earning a valid seal.

How does someone verify a Danaya seal?

They open the verification link or scan a QR code, drop in the photo or video, and Danaya recomputes the hash and checks the signature. It returns a clear verdict, authentic or not, with the sealed location and time. No account or install is needed to verify.

Who uses Danaya and for what?

Danaya is built for any situation that needs proof a media is real: listings and rentals, move-in and move-out inspections, proof that a field job was done, and secondhand marketplaces. It works standalone through capture links, or plugged into a platform via API.

Is Danaya free?

Danaya has a free plan, and the AI analyzer is free with one check a day and no account. Paid plans add capture links at volume and API access. Prices are shown in USD, converted to EUR at checkout for EU customers.

What makes a Danaya seal hard to fake?

The four elements seal each other: the HMAC signature covers the hash, GPS and timestamp together, so none can be altered without breaking the proof. A media can only be sealed once, at capture, and re-saving or screenshotting breaks the seal, so only the original stays authentic.
