Proof and Verification
DWERK does not rely on self-reported status. Every claim of work is backed by captured evidence at the moment it happens.
What proof means in DWERK
Every check-in captures three things:
- GPS coordinates at time of check-in
- Selfie photo of the worker
- Timestamp and device identity
Together these form a verifiable attendance record. Each element is stored with the event and cannot be modified after capture.
Evidence integrity
Every photo is hashed at capture time. The hash is stored alongside the record. Any modification — even one pixel — invalidates the hash. Evidence cannot be backdated or altered after the fact.
Why this is different
Existing methods produce claims, not evidence:
- WhatsApp screenshots — no chain of custody, no structured metadata
- Excel timesheets — created retrospectively, editable by anyone
- Supervisor sign-off — conflicted source, single point of trust
DWERK captures proof at the moment of work. Not after. Not on behalf. At the moment.
Task evidence
Workers can attach before and after photos to task completion records. Each photo is hashed and linked to the task event. The result is a closed evidence loop — the task was assigned, started, completed, and photographed, all with timestamps and location data.
