We take security and privacy very seriously at edX. A quick overview of how your verification photos are managed:
All photos are encrypted and sent to our secure authorization service for review. We use the highest levels of security and ensure that the images are appropriately stored for processing.
Our authentication partner is private. The pictures are not stored in their system, but the user’s name and pass/fail and reason are stored.
This data is retained via Hostway and in the Amazon cloud.
