Overview
- Digital watermarking services embed cryptographic markers for content authentication and provenance tracking. In October 2024, Digimarc released the first implementation of watermarking technology approved for C2PA 2.1 standard. Google’s SynthID applies imperceptible pixel-level changes surviving standard manipulation. California’s Provenance, Authenticity and Watermarking Standards Act requires AI-generated content watermarks starting February 2025.
