Part 6/9:
While detection is reactive—identifying fakes after they've been created—Amber's authentication approach is proactive, embedded during the recording process. This system runs directly on the recording device, be it a smartphone or professional camera, and generates a digital fingerprint—or hash—of the video as it is being captured. These fingerprints are then stored immutably on a blockchain—a transparent, tamper-proof ledger.
Using blockchain technology ensures that once a video’s hash is recorded, its integrity can be verified at any point. If someone tries to alter the footage later, the fingerprint will no longer match, revealing tampering.
