SIGILLUM — Human Chain Verifier

SIGILLUM is a system for creating, signing, registering and verifying technical evidence of provenance and integrity for photos, videos and text. Creator content is associated with an HCV-ID, signed certificates and an online Registry. When a Creator shares a photo or video, SIGILLUM first creates an official reference copy on its YouTube channel, normally unlisted, to support later technical verification and, for subscribers, visual or audio comparison with the official copy.
