What does a LockProof submission record?
Every submission records a server-set time, set when the photo arrives, and a SHA-256 fingerprint. It also records the worker’s location when the worker shares it. The phone’s own time is kept as information, not as the time that counts.

What is in the record
- The photo, taken through the live camera with the gallery blocked.
- The server-set time, recorded on submission. Compliant or late is worked out from it against when the check went out.
- A photo can be marked invalid instead, for example when it arrives after the window or its own time is older than the on-time grace period.
- Location, when the worker shares it. The reading can be up to 60 seconds old.
- A SHA-256 fingerprint over the image and the server-set time, plus the coordinates when the worker shares location, so a later change to the record is detectable.
- The fingerprint shows the record has not changed since it was sealed. It does not show that the scene was genuine or that the work was done.
- No customer action deletes a record. Archiving a check in Activity hides it; it does not delete it.
Common questions
Is the time set by the phone?
No. The server sets the time when the photo arrives. The phone’s time is kept as information only.
Does every record have GPS?
No. GPS is recorded when the worker shares location. You can require location before a worker can submit.
