Last-mile quality review
Most privacy misses happen in the final 10%: compressed previews, reflected details, or crop variants. Treat verification as part of the workflow, not an optional step.
- Run one final pass for secondary identifiers (badges, street numbers, documents).
- Open the final upload in full-screen and confirm identifiers are unreadable.
- Review reflective surfaces, including windows, paint, and mirrors.
