Digital Emblems-When markings are required, but you have no rattle-can
Bill Woodcock
DEF CON 32 Main Stage · Day 1 · Main Stage
In his DEF CON 32 talk, "Digital Emblems: When markings are required, but you have no rattle-can," Bill Woodcock introduced a novel concept designed to modernize and secure the myriad physical markings mandated by international law. Addressing a fundamental challenge in an increasingly digital world, Woodcock detailed an ongoing Internet Engineering Task Force (IETF) initiative to create "digital emblems." These emblems are intended to supplement, and potentially replace, traditional physical markings that identify protected assets, regulated goods, or authorized entities under various international conventions. The core problem this work seeks to solve is the inherent limitations of physical markings in terms of verifiability, machine readability, and applicability to non-physical assets like digital data or online services.

Bill Woodcock's talk on "Digital Emblems" introduces a critical IETF initiative to standardize and digitize the myriad physical markings required by international law. By leveraging established protocols like DNS, DNSSEC, and DANE, this framework aims to provide cryptographically verifiable, machine-readable emblems for everything from diplomatic pouches to digital data. It directly addresses the inefficiencies of proprietary scanners and the inability to mark digital assets, offering profound implications for international compliance, supply chain security, and legal accountability…
