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 capture, live

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
Sealed · hash + GPS + timestamp

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

danaya.tech/verify?code=fbwx-p9cm

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

Step 2 · Upload the media to check

signature HMAC verified

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.

Clear verdict

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.

probability → proof
Danaya sealproof
Verified at capturecryptographic

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.
