Why a normal work photo gets disputed
A photo on its own carries no independent proof. It can be reused from another job, taken weeks earlier, lightly edited, or simply shot somewhere else. Nothing in the file ties it to that site, that date and that intervention.
People often point to the file's metadata to fill the gap, but that data is editable in seconds and is frequently stripped on upload. So in regulated or insured work, where the photo is meant to protect you, it is the weakest link the moment it is questioned.
What makes proof-of-work actually hold
Evidence has to be created at capture and bound to the file so any later change shows. It also has to be checkable by a third party who was not there, without taking your word for it.
That means three things together: the exact moment, the place, and a fingerprint of the image that breaks if the file is touched. A caption or a spreadsheet entry added afterwards does none of this.
How Danaya seals a field intervention
You create a capture link and send it to the technician. They open it on their phone, with no app and no account, and photograph the work live. Import is off, so a picture from another job cannot be slipped in.
Each photo is sealed the instant it is taken: a SHA-256 fingerprint of the file, the GPS location and a server timestamp the sender cannot set by hand, all signed. The sealed proof lands in your dashboard, and your client or insurer can confirm it from a public verification link. It is a complement to your intervention report, not a certification and not a replacement for it.
